How to disable that annoying startup sound on your Mac.  Does
anyone know why every operating system needs an annoying startup
sound? My guess is it is included to scare the crap out of the
cat. I could be wrong. Anyways here is how you get rid of it on
your Mac.    1. Goto Arcana Research and download
StartupSound.prefPane.   2. After you download it, install it.
3. Go to Preferences > Startup Sound and check the Mute check
box.   4. Make sure “Turn on start up volume control” is checked
as well.   That’s it. For me, it took a couple of reboots before
it took effect.  As for the cat.. It’s doing much better.
