Gatekeeper quarantine issue with certificate
<p>Our app has been code signed. Our Apple certificate is up to date. Previous versions of our app have run just fine.</p>

<p>However, when the DMG is downloaded by the users, on some Macs the application is quarantined, but for the majority of users, it's not. So some users can open the app and others get the "X.app can’t be opened because the identity of the developer cannot be confirmed."</p>

<p>Luckily I have 2 Macs here that have the quarantine problem, but we can't find a difference between these Macs and the others. Has anyone else run into this problem?</p>
