Xcode won't start, stuck on 'Verifying “Xcode”…'

Question

I\'ve installed Xcode on a mac and when I try to start it I get a little window open saying \'Verifying Xcode\' with a status bar scrolling across, anyone got a fix rather t

Answer 1

I had the same issue (Macbook Pro, Mid 2015, OS X 10.11.15) and was able to fix it without using the terminal to bypass Gatekeeper:

1. Trash all previously downloaded versions of the file and empty the trash. (If you haven't emptied your trash in forever this may take a long time. You can selectively delete the offending .xip files manually to save time.) I found multiple instances that would not delete because they were currently in use.

2. Restart your computer. Now you should be able to delete any .xip files in the trash without issue.

3. Download the Xcode8 beta again (don't stream media while doing this to save on time and packet loss.) and open it.

4. If this doesn't do the trick, open up terminal and follow one of the answers above.
