Can't open app exported from Xcode
<p>I exported my Mac app from the Organizer a few days ago without problems. I chose "Export > Export as Mac Application"</p>

<p>Today I did a new build with exactly the same steps. The exported app works on my machine, but when I distributed it internally to other devs, they get a <strong>"App is damaged and can't be opened. You should move it to the Trash"</strong> error message.</p>

<p>It's apparently a Gatekeeper issue, but it doesn't even work if Gatekeeper is set to allow all apps.</p>

<p>Any clues?</p>

<p>PS: SIP is disabled on my machine</p>
