The Mac Observers' Mac Geekab Episode 679 from Monday, October 16th, 2017. And welcome to the Mac Observers' Mac Geekab, the show where you send in your tips, questions and cool stuff found. We share them all. We try to answer questions as they come in with the goal being that every single one of us learns at least four new things every single time we get together. Questions for this episode include Otherworld Computing at MacSales.com and their new USB-C dock. We'll talk more about that a little bit later.  All this great stuff. We'll talk more about that in a moment, too. Here in Durham, New Hampshire, I'm Dave Hamilton. And here, in what I believe is rather chilly for this time of year, Fairfield, Connecticut, this is John F. Brown. And... Here in another part of Durham with Dave Hamilton as Pilot Pete. Thanks for having me back, guys. Thanks for coming back. I got a question. Yeah? Well, how's the weather in your part of Durham? No. All right. You said we have to learn four new things. Is there going to be a test at the end? Yeah. There will be this one. The test of life. That's right. The test of life. Yeah. We'll learn new things here so that when stuff happens out there, you know, we're ready. That's sort of the... That's the goal. Yeah. But, Pete, we moved our schedule for you. I appreciate it more than you guys do. We honestly did. I got to tell you that. Dave and I were talking. It's like, well, what if we... I absolutely love coming here to do this. And, man, Sunday's were just eating me alive between the kids, church, family. And your fans are going wild, man. The fans went wild. Seriously. Both of them. I saw at least one post saying... All both. More Pete. My wife and my daughter. That's a mandate. Right there. More Pete. There you go. Hey, we got some quick tips to run through. I'm curious to see how quickly we run through them. The first one I wanted to point out, though, was that in the camera now in iOS 11, so no matter what phone you have, I believe this works as long as it runs iOS 11. If you aim the camera at a QR code and tap that code, you will get a little notification down at the top with the contents of that code. And if it's a URL, you can tap that and link to it. And otherwise, it'll put it on your clipboard if you want it to, which I thought was pretty handy. Finally, we get baked in easy-to-access QR code support. So, there you go. Did you know that, John? I did because in the past, you would have to search far and wide for a barcode scanning app. And there's almost too many of them. And I guess QR code is... Do you know if there are any other symbologies? QR code is probably the most popular that... That's the only one that I know of. Most of the C, which has the three square anchors, it's a 2D black and white thing. It's amazing the amount of information. Yeah. And then a few black dots. Yeah. It's pretty cool. It is cool. Well, I haven't done some barcode stuff, Pete. What amazes me is that a lot of these designs where you see all the dots and stuff is that they're redundant and that if part of it is damaged, it will still scan because that's part of the strategy for designing them. So... Kiwi Graham in the chat room asks at macgeekup.com.stream, of course. Does it do barcode lookup? Near as I can tell, no. I have not had it do that. But I could... Barcode lookup in what? Identifying the type of barcode? Well, no. Just translating the contents of the barcode. Like if you scan, for example, a barcode on a FedEx package, it will translate to the tracking number of that FedEx package, right? So, and there's an app that you can use for that. I use an app called deliveries from junecloud.com. Awesome, awesome app. Tracks my deliveries, syncs between all my devices. I can even access it from my Mac. Oh, okay. So, yeah. I mean, the native apps, for the most part. So USPS, FedEx, and UPS, all of their apps, last I checked, will scan their own barcodes and then save it in their database Right, but I don't want to run UPS's app and FedEx's app and USPS. Yeah, so you can find one app. I want one. Yeah, I get it. And then, as long as you're talking apps, there's another one that's really cool called Crafter, spelled with a Q-Q-R-A-F-T-E-R. Okay. And you use that to craft or make your own QR code. So you can set up your QR code on your business card that, you know, has either your email address or your phone number, or in fact, all of your contact information if you like. Nice. I still have. Sadly, it's gone now. But did you guys ever use something called Red Laser? I did. I haven't seen that in a while. I guess. Well, the thing is, I think it got acquired and pulled. But if you still have it in your database, but the thing is it did, it was pretty comprehensive in that if it saw barcode, even if it didn't, it couldn't decode it, it's like, oh yeah, this is a code 128, which is used for this sort of application. I was like, wow, that's useful. Kind of like what you're suggesting. Cool. I don't know if there's yet a universal barcode scanning app, but it's nice to have it in the camera. Bill brings us to the next quick tip. Bill says, by accident today, while searching my MacBook Air for a document named Free, I came across something cool. If you search in Spotlight for Free, it will open system information to its storage window. One that I didn't know existed. He says, the window shows how you are using your storage in several categories and gives you options for iCloud storage and such to optimize by removing viewed shows from iTunes and a view of documents and initially shows large files. So yeah, so this is actually pretty interesting. I believe this is only high Sierra. I'm going to make sure of that because I'm on a non-high Sierra machine right now because I don't tend to like it. Mind showing it, non-non-unhigh Sierra. You're not. All right, so there you go. So yeah, yeah, yeah. Okay, that's right. It's there in Sierra too. So this, you can get there by going to Apple menu about this Mac and then click Storage, Manage, at least that's how I'm doing it on Sierra, but high Sierra might be a different path. But it will show you, like Bill says, it'll show you some recommendations and then it also shows you what's using all your storage. It's kind of like using OmniDisk Sweeper or one of those apps to scan your disk and find all the large files, kind of like that. It doesn't scan everything, so don't rely solely on this, but it's certainly a place to find some large things, like in your apps folder or your documents folder. And it's pretty handy to find all this stuff and manage it. If you are running CleanMyMac, it hacks into this and adds some options called, like there's one called System Junk, I think that will appear here, which threw me off a couple of weeks ago when I looked in here and saw, like, what is System Junk? Apple wouldn't call something System Junk, and it actually would take a really long time for this window to come up because CleanMyMac was doing all this extra stuff in the background. Yep, but it then showed you more information. So, you know. That's cool. Yeah, yeah, yeah. So, very cool. And I had to search for free space, I think, on my Mac, because the word free wasn't unique enough to surface that, but free space did it for me. So, you may ask yourself, where have I seen that window before, Dave? And I'll tell you where you've seen that window before. If you go to about this Mac, storage, manage, that's the same window that comes up. That's what we just said. That's what we just said. We just told them that. Yeah, I was just following that path while you were babbling. So, sorry, but just to confirm that, but it's cool how they anticipate, oh, well, if you're searching for the word free. Yeah, maybe you're concerned about the free space on your puny little hard drive, and it brings you right to it, which is great. Yeah, or maybe large hard drive, but, you know, then of course, this feature helps you when you're asked and it's like, well, yeah, where am I wasting all my space? Right. Yeah, there you go. Yeah, exactly. Cool. All right. Thank you, Bill. Jeff has a quick tip for us. I had no idea. He says, while snapping pictures using the camera app on my Apple watch, I found I could zoom in and out by turning the digital crown and observe the results of such action right there on the watch. Pretty awesome. That is cool. Ah, yeah. And a lot of people don't even know that maybe what you're talking about. I only found out probably three months ago, so you can use the camera app on your watch to take selfies from across the room that look like a selfie. You know, family portraits, that kind of stuff. That's right. Yeah. Yeah, good point. That's right. Yep. Yeah, it's pretty cool. We're going to talk about some high Sierra stuff in this episode, but one request or question that we've gotten so much recently is I need to reinstall Sierra. Where do I download the installer? And the answer is nowhere official right now. And that's what? That's pretty common. So if you go to the app store and you search for Sierra, it's not there. Nope. It sure ain't. It might come back. You can go find El Capitan if you've got it in your purchased list. But Sierra, you cannot. There's a page for it that does not link to anything at the moment. So I believe this happened last time around, too, so it might come back. But as of right now, you can't go download the Sierra installer from Apple. So you either have to find some nefarious source online that might have posted it and then your mileage may vary or find a friend that has it, you know, because really the thing and the quick tip here is save your Mac OS installers. Any time I download an OS for the first time from the app store, what it does and this happened and will happen for those of you that are doing it with high Sierra, it downloads install Mac OS to your to your applications folder and then it immediately launches that and then you go through the install process. And once you're done with the install process, it usually sometimes it doesn't. But usually it deletes the installer app from your applications folder. So once you it's installed, it's gone because it's, you know, like four gigs or five gigs. You don't need it. You don't need it, right? There's a freeze of all that space. Before I click through to let it reboot for that install, I go to my applications folder and I either save that app off to an external drive or to my NAS or something like that. And and then it and then it lives there. And that way when, you know, I need to reinstall something down the road, I just run it. Now, that means I'm left with the, you know, point zero version of the installer, not the up to date one. If I think about it before a new OS is released, I might go to the store and redownload and get like the latest version of the installer, the last version of the installer, but but at least you have something that way. So just go go get it. Go get high Sierra right now so that you have it. I suppose I was going to say there's no Mac that can only run Sierra, but not high Sierra, right? High Sierra runs on every Mac that Sierra runs on. Which is probably why the company line, which is probably was there.  That's probably why Sierra is not downloadable, because there's no Mac that needs it because it can't go to high Sierra. But right, everything is yes, compatible. At least that's the company line, as Mr. Braun said, what's is there something that doesn't run high Sierra that should? Oh, no. Oh, OK. No, I'm just conspiracy theory. Oh, OK. Yeah, 10.5 got it. What I will say, though, is that there have been people that I've been working with and we have, you know, a few more high Sierra questions here. But one thing you may want to note to see if things have changed. Is when you get the installer, do it get info and you're going to see a version. And I've noticed, so for example, the the install Mac OS Sierra Mac install Mac OS high Sierra that got it out. It says version 13.0.66. And I'm like, that's cool. The thing is, that's not the version of the original one that I installed a while ago. And if you recall, they've released a couple of or at least one official update. But keep your eye on that version number. And because they did advertise in the most recent update, Dave, that they worded it nicely. It was like addresses installer issues, which basically mean that we tried to fix problems that people had installing high Sierra. Right, right, right. Right. And the update may do it. But keep in mind that when you download the installer and that this kind of irked me because when I looked on the App Store screen, the version that they showed was not the version that you see in the finder. I don't know why they're different. I don't think they should be, but they are at least a casual inspection that I did. But very good advice. Yeah, I have I back to Lyon. I have installers. Oh, say I've got it. Yeah, I've got them at least that I got Lyon. Yosemite, Mountain Lion, El Capitaum, Mavericks here. And and another thing to add to that, Dave, is if you want to be a developer or you just want to access to all operating systems going back to the beginning of time on the Mac, be a developer, ninety nine bucks. And then you get you can find the Sierra. Does the developer last I checked developer site has and it differs. Sometimes it'll make it a purchase in your App Store. Sometimes they give you a key code or an activation code and you just download a generic thing. But that's another thing keep in mind. I mean, for me, Dave, the value of the one of the values for me as a budding developer is that you have access to almost all tools and everything that they've made ever, ever. I think you can even get the first version of Mac OS 10. Huh. If you're a developer and you have a developer account. I do. Oh, yeah, we have to, because we have the Mac KeyCab app, which you should all go get. Now, I don't know if downloading that and using it for non development purposes is necessarily within the. Just I'm not a lawyer. We know plenty and I will refer you if you need them. But I'm happily. I don't know if that's necessarily a encouraged use of the developer program. But nobody's been knocking on my door. Yeah, yeah, yeah. Huh. All right. I'm looking to see if the same with Microsoft. When I when I did Microsoft Development, the Microsoft Developer Network, you could get back to Windows 3.1 or even prior because you may need it. I don't know that I'm seeing Sierra here. I see what Sierra was. They change their menu structure. It gets wacky sometimes. Or you may have to re agree to a developer agreement to see everything. It's a probably not something to do right now. No, I'm I'm looking in there. I don't see Sierra. I mean, I yeah, I could be missing it. I mean, I am doing a podcast at the moment. So that's possible. But but I don't see it there. I will put a link in the show notes for anyone that wants to download El Capitan, because you can do that if you get in through the knowledge base article link. So there you go. All right. And then I think we'll call this one last quick tip, although I bet we've got some other quick tips that are going to come up in the show. Todd, based on last week's show, we talked a lot about AirPods. And Todd said in iOS 11, Apple introduced a new option for AirPods that you guys didn't mention. You can customize the left and right tap controls inside the Bluetooth setting. So you go to Bluetooth, you find your AirPods and hit the little I next to it for info. And then in there, you get the normal disconnect and forget this device things. But then you can name your AirPods and you can control what happens when you double tap on the left or the right one. And you can have different things assigned to both. So you can have play pause on one Siri on another next song, those kinds of things. So it's worth going and messing around in there. You can also set which microphone it uses or any of that stuff. It looks like they need to be connected in order to do that, though, not just I just went into iOS and Bluetooth. Yeah. And I saw I tapped on the I next to my AirPods. The only option was forget the device, but I don't have them connected right now, which brings me to a question to see there. If you know, probably you don't, John, if you don't have any, could you loan your AirPods to somebody? Because I tried to the other day to my sister and it didn't want to pair up with her phone. Is there something you have to do to back them out?  We've talked about that at home because I, as I mentioned last week, I tend to lose mine occasionally. And Lisa has a pair and she said, do you know, do you want to borrow mine? I'm like, no. And the reason I always say no is because it seems like no, no, no, no. I mean, you do have to worry about Sarah Menon and all that stuff. But if Sarah Menon is earwax kids, but the probably not worried about that with your wife, right? Well, if she's got an ear infection or I do, I mean, and that's a problem. Yeah. But yeah, I don't know what, like how I would go about pairing them to my phone without, like, I'm worried that I would get them paired to my devices and then it would, you know, unpair them from all of hers. Right. Right. Because with with Apple, you can pair them. You can hit the little blue the button on the case and that puts them into like normal standard Bluetooth pairing mode. Yeah, because otherwise, Android folks would have no way of being able to pair to AirPods. So maybe if you did it that way, they would pair as sort of dumb devices and not just sink throughout iCloud, because that's what they do, right?  Look at that. There's a button on the case, Dave. See that? That's a bonus tip. There's one of your four. There you go. Um, yeah, and the button, yeah. John in the chat room is saying they'll still sink and do all that stuff. So yeah, there's a button. Well, I think I just turned on the White House Christmas tree lights with that button. But good. Well, that's good. They need them. No, I do what that button does. I got to go research it. No, that's that turns on Bluetooth pair. That's cool. That's what it does. Yeah. Good stuff. Yeah, that's right. That's why we do this show. Hey, you know why else we do this show, John? Because we have stellar, stellar listeners. And I want to take this moment to thank all of our premium subscribers that contributed throughout the week. And and while we're doing it, I also want to thank every one of you that has migrated your account over for those of you that needed to do that. We're like it. Most of you have done this already. And I'm I'm frankly blown away that that you are all like happy and willing to to deal with this for us. So thank you so much. This week in the monthly ten dollar plan, James C. Joe S. R. E. L. Paul M. J. C. Gary B. Jeffrey P. And John V. Have all contributed and thank you very much. And then in the twenty five dollars every six months plan, we've got Rob W. Andy D. William Willie M. That is not William, although it might be William M. Could be either way, whatever you like. Gary B. George C. Jed E. Steve R. And Patrick C. Thank you so much to all of you. You rock it really. I know I say it every week and I mean it. It means a lot. So that's why we do this, John. That's that's really the big reason why we do this. And if you didn't do this, our beloved listeners, we couldn't do this. It's so it's totally true. Or make it much less likely. Far less likely. Yeah, yeah, that's right. It's not like our arms are being twisted, John. We do enjoy this. So but but the fact that we're able to spend the time and do this every week is is a privilege and we thank you for that privilege. I want to talk, John, now about crack. And and I mean, whoa, whoa, when did we get into like public policy? Yeah, I'm not a crack geek. Hey, man, you know, a problem up in New Hampshire. Oh, no, that's no it's heroin. That's a problem here. It's actually not talking about crack. The the addictive with a K substance crack with a K and all capital letters. K R A C K. My what could this be? I have never. Yes, I've heard of it. Yeah, so lead us, please. So it's. Crack is a it came out today or it was announced today. It's actually been known since May and the versions of the white paper haven't changed all that much, although they became public today. Crack is describes a vulnerability in WPA to Wi-Fi encryption. Now, just to be clear, WPA to is the Wi-Fi encryption that every modern router and device use. Better use. Right. That's what and that's the that's the part that's awful about this is, you know, we've been saying for so long, just make sure you're on WPA to and then all your Wi-Fi traffic is encrypted. And well, no, that's what we've been saying. Oh, I think it's keep going. I read up on what this involves and I can equate it to a prior Mac based exploit. But but it is a concern because continuing that I'll add my commentary. OK, so your commentary was about something I'm about to say, not what I did say. That I just wanted to because we have we've been telling everybody use WPA to everything secure if you have a choice, it's not the worst thing. To do it. It's actually the best thing to do. Otherwise, your your traffic is absolutely unencrypted and in the clear and people will steal it and do bad things to you. Right. Well, potentially, yeah. So what happens with with crack and what happens with WPA to in a very sort of quick top level explanation is there is an exchange, a key exchange, and it's actually a four way exchange. Where your router or the router, the access point and the client device, i.e. your Mac or your iPhone do this exchange to sync up the encryption key. So for that connection, everything is is unique and all good. Step three of that four step process has a hole in it where someone can fairly easily and trivially inject a new key into the process that will then be used by both sides. And when someone injects a key, it's safe to assume they might be able to then decrypt what is sent across that line, because that's what the key is used for. So when you've got a third party with that key because they created it and injected it into this stream that goes back and forth during the negotiation, then your Wi-Fi is encrypted, but someone can read it. So the where this becomes and it has only been proven in the lab, but it's proven very trivially. The good news is not only does this white paper describe the problem, it describes a solution. The bad news is that every single Wi-Fi access point out there will need to be updated in order for this solution to be implemented. At this point, and we're doing this on Monday, the 16th in the evening, I believe Aruba and Ubiquiti are the only companies that have released patches for their routers slash access points to protect against this. My guess, because the fix is so clear and already documented and described, my guess is that within the next month, we will see most vendors release updates for most of their hardware. To do this. So it hasn't been seen in the wild yet, but it's pretty easy to do. All right. And so it's something to take. You give me a minute, let me get to the end and then you can have it. Yeah, it's pretty easy for people to implement this hack. Thankfully, it's also pretty easy for vendors to implement the patch for it. And so we should see this out there. Pay attention to updates for your router and make sure you apply them, especially if the release notes say that it fixes this. Where you really need to be careful is not at your home, because if someone is in your home or close enough to your home to inject a packet in there, you might have other problems. But at coffee shops and things like that, you know, our advice has always been use a VPN there, which encrypts all of your traffic tunneled through so that even the person who owns the coffee shop can't see it, even if they plug something in, you know, ethernet into the router. That you still want to do that. So that hasn't changed. Yes, Mr. Braun, the floor is yours. OK, first, your comment, I just want to qualify your comment so we don't freak people out. But you made a statement that this has been done in the lab and I think you made a statement suggesting that it's relatively easy to do what I call a man in the middle attack. That's that's a good quick description of this, sure. OK, all right, have you personally executed such an attack with with the tools available to do so? No, I have no no desire to do that. All right, all right, no, I'm just saying, I don't want to freak people out, but I don't want people to be unconcerned. So right, right, you should be concerned about this. And and but again, if you're on a public Wi-Fi network and you don't know who controls it, you have to assume that all of your traffic is being, you know, sniffed and recorded anyway. Because even with even with this patched, you're like, it's only good between it over the air once it gets to the other end, i.e. the router or the access point. People, whoever runs that could sniff that traffic. Now, this HTTPS is all still encrypted. This is this is something different. Correct. If it's HTTPS or iMessage, which is end to end encrypted as well, you don't have a problem. Right. Right. So this is very low level. Well, this is, I don't know, transport later. Transport later. Yeah, we'll call it. It's at a very low level and it's happening on the Wi-Fi's. But as you point out correctly, Pete, if you have other encryption like HTTPS or a VPN, right? Right. I think you mentioned, Dave. Yep. Then you're OK. So if you have another layer of encryption, this is not a big concern. What this reminds me of, Dave, do you remember back in the heady days of 2014 when they had something called Go To Fail? Yes, of course. I'm old enough to remember that. And when you told me about this bug or I read up on it very quickly, I heard mutterings of it, but it's the same almost the same sort of thing is that it's a unreported failure, coding failure and protocol failure in the encryption software.  Yep. That's right. And that's what's happening. I think in this case, too, is that there's a part of the SSL or I'm sorry, the WPA2 code that I'm almost certain suffered from the same thing is somebody just skipped a step saying, whoa, whoa, this isn't right. And it just marches merely along saying, yeah, this is good. We're fine. Yeah. That's right. And the user doesn't know. And that's, you know, a fish shake at the developers for not having an error saying something's not right here. They just continue on because the code proceeding said, everything is great. Go ahead. Right. Yeah. Yeah. Yeah. So I don't want to put people in a panic, but I guess if anything, I guess the recommendation would be use an additional layer of encryption if you can at all do that. And that's right. It'll be good. Yeah. And if you're having to do something highly sensitive, I assume, like, you know, transfer all your money to a friend in the Congo or something along those lines, you can always use your telephone data if you're out in public. I would say that's true. Yes. Yes. Now you're off everybody's network, so to speak. Well, you're only on your provider's network, so to speak. Yeah. Yeah. Two things, number one, Pete pointed out in our back channel here that VPNs are only as secure as far as trust, as you trust the provider of the VPN.  So run your own VPN about one where a guy got arrested because the VPN people provided their key to authorities. Sure. Oh, yeah, because they can because they can if they if they want. Right. So run your own VPN or, you know, use one that you trust. And that thank you for the reminder on that, Pete. Yeah. Yeah. And then in the chat room, Brian Monroe notes that MicroTik has also released a patch for this on their also. So everybody that's released patches so far, Ruba, Ubiquiti and MicroTik are all basically enterprise level stuff. I know Ubiquiti has some consumer level stuff. The Amplify mesh system is theirs. I don't I don't think there's an update for the Amplify yet. I think the updates are for their their their enterprise grade stuff. But it wouldn't. I mean, it's all going to be coming very quickly. Yeah. I mean, I guess the good news, Dave, is that it sounds like anyone who's anyone that implemented WPA2 did so from a now recognized flawed common code base. Yes. Well, yes, that's right. WPA2 is that everybody took the official WPA2 code or you would hope that they did. So hopefully the fix should be deployed. Well, it's the standard. They followed the I don't I don't know that I don't think they would all have used exactly the same code base, but they followed the same just the same definition of the protocol and that by the it's the protocol itself. No, I don't know. It sounds to me like a coding error.  It's actually an error in the standard that needs to be patched. It allows this so the standard did not dictate a certain correct a certain level of taken to assure security of the key exchange. Correct. Correct. That's the problem. That's why everything is affected. It's not just like, well, people that used, you know, Timmy version two code are affected and that's, you know, links this and so on. So you would think these things would be subject to peer review and they are you this week and we've for years, we've thought WPA two was safe. But I'm still all these years. Yeah, it still is as far as you know. As far as I know, it's safe. I mean, I know that it's not because I've I've read up on this. If you can choose to say whatever you want, but it's there is a hole in it. Yes. Oh, yeah. Well, everything is the other interesting thing in this article that I'm reading about it says that not just your router, but all your devices need to be updated with the security patches because it's it's the two way issue. It's a two way issue. Yes. Updating the routers, it solves starts a huge, a huge amount of it. But there is still a the possibility of of an attack. And it's a it's a fun question because, you know, in the ecosphere of devices that have software on them. How many even bother to let you update the firmware?  Yeah, scares right now. And people are like, well, how do I update the firmware on my, you know, brand X, you know, light switch? It's like, well, you know, most of the new people give IoT devices a bad rap for this. And, and I think the landscape is is varied in that you got good people on Nest and, you know, well, maybe they're not good. But but they're you got major vendors deploying IoT and then you have these, you know, kind of, I wouldn't worry about any IoT device that you bought in the last three years. Okay. Well, because it's new. And so it like it's they are they're built to be updated. It very few of these things are just, you know, hardwired. They all are using the very standard chip sets and things. So updating the firmware on those things, I wouldn't I wouldn't see as a problem. I mean, you need to pay attention and go go get it when it comes out because you might not be alerted to it. And you need to stop and think about what devices do I have that use Wi-Fi and all of that. Where I would really worry is your, you know, five to 10 year old printer that supports WPA two because I guarantee those aren't going to be updated. I mean, like that that's where these holes are big time for me is is those kinds of things where it's like, yeah, I keep this device around forever because who cares might it's just a printer. What's the worst case threat of someone being able to inject something through your printer, though?   Yeah, really what it is is they can they can see the traffic going between at the very least between your router and that that one device. Right. And then depending on how secure your router is, your router may let all the other traffic be seen that way or it might not. But but yeah, they're just seeing traffic. It's not like by doing this, they can hack into your max file sharing unless you send your file sharing credentials, you know, in an unsecured unencrypted rather email to someone and you're sending that email in the clear and not over a TLS connection or something like that, which for most of us isn't going to happen. You're probably not encrypting your email unless you know that you are. But even then your emails being sent over a link that's also encrypted separately from your Wi-Fi link. So it's you're right.  But it's like, yeah, this needs to be fixed to work hard. If you have the convoluted nature of it, what's encrypted, what's not anymore. Right. Right. So I think that the closing message here is that if you have a vendor that makes Wi-Fi stuff, go to the website and see if they have a firmware update. Maybe they'll tell you. I mean, a lot about the equipment I have says, hey, there's an update because there's something wrong. All right. You may have searched for it on your own. And actually that can be quite painful. Dave, I found with certain vendors finding firmware updates if they do if they even exist. So well, join our our Mac Keycap group on Facebook. Go to MacKeycap.com Facebook. And if you're having trouble finding the firmware for a device, post there, we've got a lot of very, very good and very, very smart people that follow along in that group and we're all happy to help each other. So it's good stuff. I want to, we have some cool stuff found to go through John, but the first thing that I want to do is, or the next thing I should say that I want to do is I want to talk about our sponsors. Does that work for you? Outstanding. All right. Our first sponsor today is Stamps.com. I'm going to tell you right out of the gate.  Click on the radio microphone at the top of the home page and type in MGG. That gets you up to 110 bucks worth of supplies, postage and a digital scale and a four week trial of Stamps.com's awesome service. In the old days, like yesterday, if you aren't using Stamps.com already, businesses would use a postage meter, right? The problem with a postage meter is expensive ink. It's archaic technology. You're in a long-term contract. No. Stamps.com, fraction of the cost, way more functionality and no long-term contract. You get discounts on your postage there. I needed to send out even just like a letter that was priority mail. I got a discount on that for using Stamps.com. Here's the best part. I did it all right here at my desk. I went online to Stamps.com. I chose that I wanted to send it that way because I actually wanted to send it priority, but you can send anything you can do at the post office.  Whatever you want to do, whatever you can do at the post office, you can do on Stamps.com. So I chose that. I have the scale, right? It's USB into my computer. I put the thing on there to make sure it wasn't more, even though that's flat rate. I did it anyway because it's cool to have the scale and use it. Sure enough, it said, yep, that's great. Here's the price. I paid it and I printed the label and I put it on there and I gave it to the mailman. It's amazing how well it works. You got to check it out. It's so good, so easy. You can totally do this at home and then you get to avoid the lines at the post office or you can bring it to the post office if you like the lines, but at least you printed your postage and gotten your discount at home, right? Check it out. As I said, Stamps.com, first things first. You click on the radio microphone, you put in MGG. That's Stamps.com, enter MGG, never go to the post office again, get some discounts, get a four-week trial or thanks to Stamps.com for sponsoring this episode. Our second sponsor for today is otherworldcomputing at macsales.com. They've got their new USB-C travel doc. They just launched this product a few weeks ago and they've had a huge response to it. What it is, is the perfect little thing for any USB-C MacBook, much more compact and portable than the Thunderbolt 3 doc and also very affordable at $49.99. It's a cool little kind of puck-sized thing. Two USB 3.1 Gen 1 ports, USB-C auxiliary power up to 60 watts, an SD card reader, an HDMI 2 port, supports up to 4K resolution, up to 4,096 by 2160. It's available in four colors, $49.99. Very cool. You need RAM. OWC's got RAM. You need SSDs. OWC's got SSDs. Whatever you need to expand your computer, OWC is the first place I go. You've got to check it out. Visit macsales.com. Make sure you let them know Mackie Keb sent you. That way they know that you're listening and we appreciate that. They appreciate it. It's good for all of us. Our thanks to OWC for sponsoring this episode. All right, now it's time for some cool stuff found. Are we ready for cool stuff found, John? I'm never ready but hit me. All right, the first one comes from Tannel, who says, some time ago a listener wrote and asked about note taking software that would sync but not over the cloud as his employer did not allow it. I don't remember this app, but there is DevinThink. It allows a number of ways for syncing and can also do direct over Wi-Fi syncing between the Mac and your iPhone and iPad. DevinThink's been around for at least as long as Evernote, possibly even longer if my memory serves me well. He says, I have been back and forth between DevinThink and Evernote for a long time and since DevinThink did not have cloud syncing until recently, I kind of used both apps together. Now that DevinThink has cloud syncing via Dropbox or an arbitrary web dab server, I am now exclusively on DevinThink. He talked a little bit more about how he migrated over. It'll import your Evernote stuff, and it is pretty cool to be able to control your own sync engine so that you're not syncing with someone else's cloud because Evernote data is actually stored unencrypted at rest. It's transmitted encrypted for the last discussion we had about crack, but it's stored unencrypted so that they can do searching and things like that. So there you go, that's DevinThink. One question I had for Tanel about DevinThink and I don't know that we've heard back yet is whether or not you can share a specific notebook with someone else. Like I know I can sync my notebooks amongst all my devices, but for like what we do, John, we have a Mac eCab notebook that has all of the questions for the week in it and those sorts of things that we share. I would, if we were going to move to something like DevinThink, I'd want to be able to preserve that functionality. So that was my question for Tanel or anyone else that knows. I couldn't easily tell on their on their website, so. Would that be a good replacement for notebook? For notebook? From Circus Ponies, which doesn't exist. It might be. For Circus Pony died. Yeah. I guess when Ringling Brothers went out in business or something. Yeah. Yeah, because I'm still using it, but I know it's going to be end of life before too much longer and all my notes. Right. Right, for sure. Yeah, I keep meeting minutes and all that for my chat. Oh, yeah, yeah. Yeah. I'll look at it. And I'll toss in the ring here. Go ahead. Devin also, so you know, I've never quite, I guess, groked their tools. I've used them in the past, but the only thing I'll mention is that they do have a number of free applications. And yeah, as pointed out, they've been in business like forever. Right. But they do have some things that I've come across in research and questions for listeners. And they do have a freebie called Easy Find, which is, looks to be, so they have very powerful back-end software that, while it finds things. Right. Because that's what they do. So they got one called Easy Find. They got one called Photo Sticky, Thumbs Up, X Menu, like four of them. And we'll link to them because we want to do that for you. But I'm, yeah, a great member of the community. But I've, they haven't, they haven't got to mention from us in a while. No, it's true. It's good that we do because it's just, again, what they do is not on our radar. I guess they're into like big data. Well, it is now. Right. There you go. Back on the radar. I like it. So we've talked about devices in the past that can sit on your network and monitor for when either you have an attack coming in or having an attack, have an attack going out. And we've talked about how some routers will do this now. You can buy an ERO plus subscription if I have that terminology. Yeah, they keep reminding me of that when I run the app. Yeah, right. You can buy the subscription for that. The TP Link Deco router has, or mesh has that built into it, but it's also a router. And there's various ways of doing it. But if you're running a router that doesn't have that functionality or you want something more or more controllable, there are companies coming out with standalone devices. And one that I've been looking at lately is called Kujo. Get Kujo.com. Nice. Yeah, that's right. They call it a smart firewall. It's a device that sits on your network and monitors everything that's going on there. The way it works best is if you let it set itself up as your gateway. So what would happen, and we talked about this when you talked about that bit defender box. Do you mean your router or you get it? All right, so similar to what I looked at. So it wants to have primary control of your network. It wants to have all of your network traffic flowing through it. It wants to be the router. It wants to have all your network traffic flowing through it. It is not your router. Your router remains your router. So you could do some, go on. I'm intrigued now because that's a different approach. Right, it's a slightly different approach. Although it can be used the way the bit defender box was, where it's truly in between your router and whatever lives upstream of that. The way it's built to work is you just plug it in with one ethernet port to your router, much like you would say your Apple TV or any other device that would just be ethernetted into your router or switch on your network. And then it wants to essentially have your router turn off its DHCP server so that the Kujo can hand out addresses for everything on your network. And the reason it does that is to then route traffic through it. So it can see everything that's happening. So would you call it then active? Very active. Rather than being something that you hang off of your network, which I believe we've heard of such devices that will then maybe at some point in the future say, hey, I saw something bad. This is in real time like the things we looked at. Looking at your traffic and if something bad happens then okay. That's correct. Yeah. Just wanted to know. No, that's right. And it's got gigabit ethernet in it. I was able to pass traffic through this thing at over 500 megabits a second. So I don't think it's going to slow you down. It, you know, it runs well. Don't gloat. I'm sorry. What's that? What am I gloating about? Oh, my internet speeds. Well, I needed to have fast internet speeds.  Yeah, I know. I know. I had to do it. So at the risk of asking you how to build a wristwatch, how does it, how does it work for the wired items on your net? So everything, it is not a wireless device. So every, it is only wired in. Okay, so it's a wired firewall. So the ports on it are as follows. Hardware firewall, essentially.  It, it does its level best to, to make sure that's happening for you. It's, it's basically built. Is it like what I worked with? Yes. You know, except for the speeds. All right. So it's power and two ethernet ports in and out. Is that? No, yes. So it has two ethernet ports. Most people will only use one of them. It just hangs off your network like a printer or an Apple TV. And, and everything goes through that ethernet cable twice. And data goes into it and comes out. Now you can use the other ethernet port to go downstream to something else. And, and I've tested it that way too. And it, it works fine. It, it's two hundred and, two hundred and forty nine bucks, I think is the, is the price. I want to make sure I have that right because I think I had it. Yeah. It's two hundred and forty nine bucks, no subscription fees. And it just sits on your network. I've been, it's hard for me to, this is why I left this in cool stuff found and not, you know, a more formal review or anything. Because I can't, I already know my network. I already have everything in place to protect myself. It's hard for me to test a device like this and be wowed by it because it's not going to do anything that I want done that's not already being done on my network, if that makes sense. By perhaps another tool. Yeah, you've got a little bit of technical expertise. That's what I'm saying. Probably set these things up anyway. Correct. I've, I've already done all the heavy lifting. The nice part about this is you pay two hundred and fifty bucks. You plug this device in it, for the most part, will reconfigure your network for you. And I will say this, their support is proactive. I, I plugged this thing in. It saw what I had on my network and said, you have to go through a manual support process because it saw that I already had things doing this job. And it said, you need to call Kujo. Now, I did this yesterday on a Sunday. You have to call Kujo to set it up. And I thought, okay, first of all, it's Sunday. And secondly, I was going to do this while I was watching the Patriots game.  And it's perfect for me because I can sort of, you know, half watch football game or whatever and, you know, and then focus on this stuff. I thought, all right, well, I'll call them later. 30 seconds later, my phone rang. And it was a support rep from Kujo saying, hey, I'm here to help you set it up. And it was like, at first I was a little annoyed because I was like, I actually didn't want to do this right now. I had already made that decision. But he was very nice. And he explained it to me. I told him, I said, I don't have a lot of time. I had plenty of time, but I didn't want to spend a lot of time on the phone. That was the rep from Kujo with a K and you gave him all your passwords. Not to worry though. That was right. That was interesting. It was like, you know, is this the Microsoft tech support rep calling. But I said, look, you know, I know a lot about networks. Can you give me the, you know, the distilled version? And he's like, yeah, it's reading your art table. It's seeing this. It's doing that. If you want to use it the way you want to test it, he's like, use both ethernet ports, run it as a path through, pass through on one of your other wireless networks. And that way you can control it without it completely, you know, taking over your network. I'm like, all right. Thanks, man. We were asked that I understood what you said to me in GeekSpeak. I want to give these guys like three thumbs up. Yeah. And there's support. Yeah. Well, you got the, you got a tech support person. So a lot of times you have to wrestle with tech support to get to level one or two or three or whatever. Correct. You explain to him, you know what you're doing and immediately all the barriers came down because what you said is what I'd want to hear from a very good experienced tech support person. And that, look, I understand steps one through 10. I need 11 because yep, that's all I need is I all I need is 11 and 12. I've done one through 10.  I know what they are. Don't waste my time. I don't want to waste your time. And he's like, okay, we'll bring you to 11, which is what he really did. Yeah, no, he really did. Yeah, he was great. He was great. So. Outstanding. So you got a revised configuration. I did. Correct. Yeah. And it really is like if you don't already have something on your network that's doing this, it will look at all the traffic that's there. Like I said, I can't sit here and tell you it's going to find all the vulnerabilities that they say it's going to find because I don't have any of those on my network at the moment. So, you know, it's hard. It's hard for me to to review it other than to say set up with great. Like when I test another product, Dave, I tried. I intentionally have a bookmark to a site that has a unsecure form submission. Right. On a web page. And I'm like, let me see if this product identifies it. And it didn't. And I'm like, well, you said you detected insecure, blah, blah. And they're like, oh, well, but not that. And I'm like, well, okay. So I said we were going to do this as a cool stuff. Found another review, which means going quickly and in my own mind, spending less than 10 minutes on it. And so we're at nine. So we're going to move on, but I'm happy to answer questions about it. And I'll of course leave a link in the show notes. Another similar device, but but actually quite a bit different is this device called the eBlocker. And the eBlocker similarly sits on your network and only protects your browsing traffic.  Okay. So is it not a box? Like it's a box. It's a box. Oh, it is a box, but a specific box. It's a specific box only for browsing. And honestly, you know, I don't consider this cool stuff found. I consider it like it's priced very similarly to the Kujo. It's $219 for one, essentially one configuration that everybody in your house shares or $240, sorry, did I say $119? $219 for one shared user that everybody or one configuration that everybody shares. And then $249, $30 more for 10 profiles that you can assign to different devices. But it only protects browsing. And I, like, I'd had some people asking about it, which is why I wanted to include it in this discussion. If you're going to do something like this, it seems to me like the Kujo or things like that are much that protect your entire network and all of your traffic as opposed to just your browsing. The eBlocker wouldn't do SSL sites out of the box. You have to install its certificate on your Mac because otherwise it can't see what's inside there. So, yeah, like, I don't know. Well, I'll play devil's advocate to say that most data that is disclosed is probably done while people are browsing with the browser with phishing attempts, right? Right, but it's not going to tell you if your webcam just joined a botnet attack, which the Kujo, in theory, could... Okay, well, because it's network-wide and not specific, but... Correct. But again, the point is... Here's the cool thing. There is a cool part to eBlocker. So, I get the focus of it. So, if you're only concerned about browsing security, cool. Right. But here's the cool part about... Network-wide is what we want. Are you... Oh, yes, I think there is something cool. I'm eager to talk about it. You can set up eBlocker OS on your own Raspberry Pi. So, you can download it for free, and then you'd pay a license to use it just like you would if you bought an eBlocker. So, if you have a Raspberry Pi and you want to run this thing, you can download eBlocker OS and install it on that and off you go, and there's a link in the show notes for that, too. So, which is pretty cool. I like that, you know, right? No. Did I lose Mr. Braun? No, we're here. Oh, okay, all right, cool. I'm letting you talk. Got it. All right, there you go. Thank you. I want to talk over you, too. I deserve it. And I do have a Raspberry Pi. I know. So, I'll put it around here. Somewhere around here, and I may actually find out what it does or reprogram it. So, yeah, embedded development is... Yeah. Is the B... Yeah, and what it's blocking for... Somebody in the chat room asked, wouldn't Open DNS do the same thing? No, this does more than that. It looks at the content and the resources loaded by the website. So, it will block trackers. It will block ads and things like that. And it will let you do it on all your devices as opposed to just those where you install some software to do it. But yeah, a lot of this could be done with software. But I think the difference is that Open DNS looks at where you're going. Right. That's it. And this looks at what you're doing. Correct. So, they're almost complementary. Well, no, you... Yeah, they make a hole. Right? Yeah. We want to get this in here. That's right. But the thing is, you can focus your attempts or you can open it up, but it doesn't hurt as we talked about in the past. They have multiple... Right. That's right. Secure yourself, whether it be VPN or intrusion detection. I don't talk about watch bands a lot on this show. And that's because, by and large, there's one watch band for the Apple Watch that impresses me and that I use most of the time. And that's the one from Hello Nomad. They've got... I think they just call it the band. I always confuse this when I go in there. Apple Watch Strap, they call it, I think. Yeah, it's the Strap. And they've got a couple of them, actually, now. The Leather one is the one that I really love from those guys. It's just awesome. However, I got one this week that I thought was going to be just a kind of a joke. And it's not at all a joke. And it's the Xdoria Action Band. It's a rubber band for the watch. It's two pieces, but the way it locks in, if it started to come off, it wouldn't come off. It's very well engineered. Oh, look at that latch. I can just see on their web page, they're like, hey, look at this innovative angled thing. It's like, oh, I get why they do that. It's got this latch that really buttons in. But even if that were to come out, it still wouldn't unlock because the way that it all fits together, you have to really work to...  And it's lightweight. They've got it in a couple of different colors. And it's sporty. And I really liked it, 25 bucks. So I'll put a link to that. What's the material over there? Rubber. No? All right. So it shouldn't annoy most people. No, no, exactly. Yeah, yeah, yeah. And the colors... I have to... One thing I have to say, the one that I got... That looks psychedelic. Well, they look psychedelic on the website. What you'll see is you'll see a different color on the inside of the band versus the outside, which is very obvious when they're showing you these bands on the web because they're not on someone's wrist. Once it goes on your wrist, the colors become much more subdued because you're not seeing the color on the inside all that much. It's aiming at your wrist. So it's actually... It works out. I like them. So yeah, there you go. So that's my watch band thing. I got a couple more. Good? Yeah? Yeah, I'm willing to listen. All right. I got nothing right now, so go. The... You know, I'm a fan of listening to music wherever I am, but it needs to sound good. And then all the cool stuff comes after that. And JBL with their Pulse 3 speaker, which is no surprise the third one in there in this line, delivers awesome sound. And they really finally got the concept with the first pulse and the second pulse. And of course, with the third one, the goal was to give you this sort of lava lamp-esque view that moves in sync with your music. And with the first two, they sort of got there. I mean, it gives you that feeling, but there was a screen around it on the first ones, and the lights weren't as bright as they could have been. And they... Okay. Now, is this a wired or wireless? Wireless Bluetooth speaker. Only wireless, no wired? You could wire into it if you wanted. You could line in or mic in. Yeah. It's got a line in. Okay. But the primary goal is Bluetooth. Bluetooth. Yep. It's wireless. It's waterproof. It could fall in your pool and you'd be fine, which is...  Why would you need that? It can be rained on and you would be fine. What kind of life do you live? Oh, you want to bring a speaker to the beach? This is it. That's... No, it's great. Oh, we don't live near a beach, okay. I know. Yeah. I never thought to bring a speaker, because, I mean, the beach, I mean... I throw one of these into my suitcase when I travel. It's great to have in the hotel room, because it does this lava lamp-like thing, and so it lights up the room nicely. But because it's waterproof, I can bring it into the shower with me and listen to music while I'm in the shower. It's great. So, 200 bucks. I want you to... So, there you go. What's that? We won't discuss shower protocol. Okay. There you go. There you go. Just going to step away from that. Pilot Pete, last week we talked about custom fitted earphones. We did, indeed.  I did. I went out and bought something right away. I went right out to Amazon. I put a link on there to the one I used to come. And I got some radians. They're essentially ear plugs, custom molded. They come like an epoxy in two different little jars. And you mix them. You cut each of those in half, so you don't mix them all at once, unless you want to do both ears at the same time. I did not. Then you mix them together. You got a couple minutes where you get it until it's all a uniform color. Then you start... Follow the instructions that come with it, how to stick it into your ear and fold it in more and smooth it out and all that sort of thing. So I did that. But the other thing that I did, and I don't know where I found it, I found some instructions on the web that I kind of followed and then modified myself. What I did with money, these I think are skull candy headphones. Okay. But any kind of... Be it cheap or expensive, sorry, any kind of cheap or expensive earbuds will work in ear earbuds.  Take a little rubber piece off, get that all folded and molded into your ear, stuff it in good and far, and then take the earphone and stuff it into the molded ear piece and then sit there for the 10 minutes or so that it takes. It says 10 minutes to let it cure. Sure. And you want to do it...   No, you're totally right about that. And I meant to bring this up last week when you're going to an audiologist to get molds the same thing. They should tell you to keep your mouth open. In fact, a lot of them will put what they call bite blocks in your mouth to keep it open. Some of them will tell you to keep moving it during the process, but if they don't tell you and they let you just keep it closed the whole time, you are at the wrong audiologist. But how does that make... You're not going to get a good seal.  Okay, I'm just...  So why would you take a mold? Okay. I'm sorry, John. I had to jump in on that one. But no, I'm just thinking the physics of this. No, I value your input. What you don't want and I've been through this is... So is it better that it's larger because your mouth is open? Okay, correct. So you're creating a better seal when your mouth is closed. And also you're providing some delta there. And you don't want it to unseal just because you happen to open your mouth. Wow. Guys, I've learned like... See? Four things right there. Oh, like 12. Okay, so Pete, I mean, these things are... So I did it. And these are sold and advertised as custom molded ear plugs with a 26 decibel reduction, I think, is the average rating on them. Yeah. And then there are some tan ones there that I wish I'd have seen when I was ordering mine last week because mine are blue, but tan ones are even more inconspicuous. Right, right.  There's not a hole all the way passing through the custom molded ear plug so that your... Yeah, because it shouldn't have a hole in it. ...headphones can get in there, right. Yeah, so you're going to need that if you want to listen to your headphones. You're going to have to take these out. And I've tried it two different ways. The most effective way is take the molded ear plug, take the headphone out, place it in the freezer. Sit in the freezer for half an hour or so. So that it's brittle. That it's brittle. And then I just took a drill and I want to say it was... I think it was a 316 drill bit and drilled right through, straight in the direction that my headphone mold made it in there. And then drilled right through, I got a nice, brittle, straight, clean cut canal. If it's soft, it's going to mold and fold around it and all that. So if it's frozen, it does a better job of cutting a nice hole out there. And then I was able to... You can take the headphones in and out of the ear plugs after that, particularly. Yeah, I've been seeing you using them here. I mean, you're using them just like I would use custom fit ear plugs. And let me tell you. And these are 10 bucks or 11 bucks. 10 or 11 bucks and they're probably even cheaper on some other sites I was looking around. Dude, you've crossed the divide between chemical engineering and mechanical engineering, just being this in this exchange here. It's like... A little executive noise, the drill. Plus, I know better. So I'm going to... No, I'd like that you've defeated the original design. Well, and here's the other cool thing that I've done. And I did it, wound up with it just today for years. And because I've been around jet airplanes for 30 years now. What? Am I here? Yeah, exactly. My hearing is very, very, very frustrating. When I'm in a crowded room and my kids are talking to me or anybody's talking to me for that matter, I find it very difficult to hear. All right. I can't hear the TV if there's conversation in the background, that sort of thing. So I'm starting to get that level of hearing loss drives me nuts. And part of it's been for years, I know, riding around on the lawnmower and listening to music with earbuds in without properly attenuating the sound. Yep. Today I was on the lawnmower. I had the music on with these in and my volume was at about one quarter. Yeah. On the whole thing. So... This is why I've been obsessed like this since I was 15. No, seriously. There's... The last time I had my hearing checked, which was... I'm 46 now. I think I was 41 or 42. It's been a little while, but they told me I had the hearing of an 18-year-old. Now, I'm sure it's worse now than it was then, but, you know, to be over 40 and have a doctor say that... Oh, to have that frequency. So that was judging you on your sensitivity and the two various frequencies. Correct. So it was a standard test. Yes. Okay. Yeah. You can hear at this.  I think it was 30K and it was like, huh? You're not going to hear 30K. But the good news is you never heard 30K. Or even 20K. And we've had this discussion with music is like the range of human audible music and what you think you hear and what you want to hear. It's technically, I mean, the accepted range for humans in general is from 20 hertz to 20 kilohertz. 20K. Okay. So that's the high end on any human. Most people, even kids, don't hit 20. It's usually somewhere between 16 and 18, which is where things top out. And most adults aren't going to get much above 12, to be perfectly honest. Yeah. In fact, that's probably shouldn't mention this, but a lot of the kids are using what they call mosquito ringtones. Yes. You know, so those teachers don't hear. Yeah. Parents and teachers don't hear it. They're in class texting each other. My kids ask me, about 10 years ago, I wouldn't, you know, or whatever it was that the kids got, like iPhones or whatever they're like, hey, dad, can you hear this? I'm like, yeah, of course. They're like, oh, dang it.  You should be deaf. I'm like, yeah, but I'm a drummer that at 14 read an article about another drummer who was deaf. And since then, I've worn earplugs.  I want to enjoy playing music. All right. I'm getting back to the Mac stuff. In high Sierra, Bonjour is no longer a menu option in Safari, which means if you had a printer or your network storage device or anything else that you would configure with a web interface, you used to just go to the bungeor drop down or the bungeor thing in the bookmarks menu. And you'd see it listed there because that's what bungeor does. It allows things to advertise themselves. And the Apple took it away. Right. It ain't there. I have two things that can solve this problem for you. One is an app for 99 cents in the Mac App Store called Local Sites. And that will that will do this. And then another one called which you might have. It's called iNet Network Scanner. And that's also available in the Mac App Store. I don't know. It's $14.99. There you go. Okay. When I looked at it on my other device, I bought this years ago, so I couldn't tell how much it was, but it's $14.99. And that, among other things, will show you your bungeor devices. So if you want more functionality than this, the iNet Network Scanner from Banana Glue is a great piece of software. But if all you want is to see your bungeor stuff for 99 cents, that little local networks thing will put a thing in your menu bar and it'll show you stuff. And you choose it and then it opens it in Safari. So there you go. I get a closing thought. Yeah. Our friend Flame. Yeah. Yeah.  And hey, you got an IP address. So there you go from huska.org. Right. Then you could just visit it. Oh, yeah, yeah, yeah. I like it. I like it. I've used it numerous times, Dave, especially when I'm on Guest. Oh, sure. That works. You want to see who's there? Yep. You're on Flame. So bungeor is good because it exposes your device to the network. And then you could do things with it. It's bad if you're on a public network because then people can stalk you and make your life difficult. There you go. And lastly, also for the Mac, is a piece of software called Fenetri. I don't know. I'm sure I'm mispronouncing that. F-E-N-E-T-R-E at G-E-T, F-E-N-E-T dot R-E. It allows you to put anything in a picture-in-picture window on your Mac. So if you're on one of those, you know, conference calls and it's got the thing that wants to take over your screen, you can put that in there. But you can also put, you know, a browser window with Netflix in it or whatever you want. Doesn't matter. It's yours. You get to do it. Right. So Fenetri's the French word for window. So. Ha! See, there you go. See, I asked you pre-show if you spoke other languages and you said you didn't. See, I gotta get around. I said I gotta get around. We acknowledge that. That's right. In a good way. Bonjour. Yeah. So there you go. So that's the cool stuff found I have. I said we had some High Sierra stuff to talk about. Really, the only thing we have time to talk about is some High Sierra apps and one tip. So we will go through a couple of these apps and then there's actually going to be two tips in there because it's just how we work. So Pixelmator, which is for most of us far more than we'd ever need in terms of an image editing and manipulation app. And for not only for my money, it's of course way cheaper than Photoshop, but it's way easier to use than Photoshop. It's 30 bucks in the Mac App Store. And of course, they've kept it up to date with version 3.7. Added High Sierra support. You can launch Pixelmator now from the Photos app and save your edits back to the original image so it can work like a plug-in that way. It supports the HEAF or HEIF images. You know, these folks stay on top of it. And of course, it does iCloud stuff, which is always done. And you can sync images with your iPhone and the Pixelmator app there. Just wanted to give a shout-out to that. I use that app every day and love it. And it's weird. We probably have never... Maybe we've talked about it on the show, but it's been a while. So Pixelmator literally couldn't live without it. Well, if you're going to give them a shout-out, then I've got to give Graphic Converter 10. Which I threw down some coin for these guys. Yep. Because they've been around since the beginning of the Mac. I don't know. No, I've looked back. I actually have paper invoices. I was looking through old papers. I'm like, should I shred this or should I keep it for posterity? And it's like, I got a Graphic Converter invoice from like 19... So did they add some stuff for High Sierra? I don't have information on that. So right now I have Graphic Converter 10. That's their latest. Okay. Okay. All right, cool. I will have to look, but I mean, dude, in the grand scheme of things, they... I mean, Graphic Converter, it's like... No, I was just trying to get some things in for High Sierra. But... No, I get it. Yeah, yeah, yeah. So the next one that I had on our list, which I think we both use is iStatMenus. Version 6 came out for along with and for High Sierra. And in addition to having support for High Sierra, they've added in quite a few cool new things. They added weather. So iStatMenus is the thing that John and I keep at the tops of our screens in our menu bar.  It replaces the lights on our modems that we can't see. It's just, it's stellar, right? You can see how much disk space you have. Don't you remember that? We had modems with lights on them, John? So it is that. And it always has been that. Version 6 adds a weather widget. So you can not only see the temperature, but you can actually have it notify you with the forecast every morning at a certain time. They've added a ton of notification center support. You can get notifications when your CPU has been, say, above 50% for more than 30 seconds, which is super handy if you've got some runaway process, right? And you're not necessarily paying attention. Oh my gosh, I hadn't even seen that.  It's like, dude, what's wrong? There's a notification center. Go to sleep. Go to sleep. There's a notification center widget now, which will show you sort of an encapsulated view of everything that's going on with your stuff. You can, and then for people that have been using iStep menus for a while, you can reorder things in your drop-down menus now, and they've given you more colors and things like that. So I'm really enjoying this. And now, I don't think it supported this before. I certainly didn't have this turned on. It can show you the clock speed of your CPU, which might not always be what the maximum is. Like your max CPU's speed changes depending on how loaded it is. And of course, that keeps... Right, hyperthreading and... Well, yeah, hyperthreading, yes, but just the actual speed, the clock speed of your CPU, is variable. It has a maximum, and that's what they tell you when you buy it. But if you don't need that, it actually scales back so that you're not using any more juice than you need to. You have to install this thing called the Intel Power Gadget, which they will link you to. You got me. We will link you to, too, but there you go. Actually, I think iStep menus at some point said, hey, I got to do this, and can I install this Intel Power Tool? There you go. Power Gadget. I'm like, okay. I'll get back to you on that. When I was like, well, I can't do this thing you ask, and I'm like, well, I said you could. Yeah, you need to install the Power Gadget, and what I found was you got to reboot after you do that, and then iStep menus is happy. One last thing, cool stuff found in macOS High Sierra. They have something. If you go into system preferences into the sharing tab, there's something called content caching that you can turn on. What this lets you do once you turn it on is it will turn your mac into something that previously was only available if you had macOS server running. It will cache things like software updates, apps, and depending on what options you choose, other content on your computer. What that means is, when let's say on your iPhone, you go and update the Mac Geek app. That update will be saved to a Mac that you have turned content caching on with, and when the next person goes to update, they won't download it from the App Store. They'll download it from your content cache locally, speeding that up, saving you bandwidth. So even if you're just one person and you've got multiple iOS devices, having this type of content caching is great. If you've got multiple Macs, now your High Sierra updates will be cached, all of that stuff. You can then turn on iCloud content so that your photos and your documents and all of that stuff is also cached and is now basically syncing locally unless something needs to be sent to or from the cloud. You can, in there, it's a system preference pane. It's the sharing pane. You've seen it before. If you hit the options button, you can choose where to store your content cache so that you don't have to store it on your boot drive. You can store it on an external disk, which is actually what I've done. And you get to see how much space is used. And that's all. You don't get to see what's in the cache. You can wipe the cache out, which is good if you're having some sort of a problem. But you don't really get any granular view into what's in the cache. It's in, if you go to whatever drive it's on, it's in the library. I think it's the application support folder in there. But when you dig in there, you won't see anything that is recognizable. Everything's just got ID names or numbers associated with it. I've turned it on. I've got 10 gigs of stuff cached and I feel better about it. But I haven't been able to prove that an iOS update is coming from my computer versus over the cloud yet. It's because you've got high speed internet, Dave. I know. I've been trying it anyway, though. But you know. But one of the important things you stated in there, very early in that tip was that that's high Sierra. Because I followed you all the way through and then didn't find it anywhere. I'm going, oh yeah. It is available in Sierra, but you have to install macOS server to get that preference. Right. Sure. Right. Right. It's on her. I don't see. My conclusion is no, sir. I don't like it. Why don't you like it? Well, harking back to the days of Ren and Stimpy with the horse saying, no, sir, I don't like it. I'm uncomfortable with multiple locations having a cache data storage device. That's all we're going to say. All right. This is one location. Well, but then you indicated that it could be shared with other people. So then we're, we're. No, no, no. Other other people on the network will use this cache. I still don't like it. And if you don't like it, get off my lawn. I guess.  And also if you're listening and you don't like it, or if you do like it, or if you have a question or chip or comment, you could send an email. To feedback at mackeygab.com.
