Answer 1

Also you can remove Open Warning for entire directory Applications via the command in the terminal:

xattr -d -r com.apple.quarantine ~/Applications

Answer 2

If you don't want to wait forever, this might help:

xattr -d com.apple.quarantine '/Applications/Xcode.app'

Answer 3

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.

Answer 4

If you are not logged in to Xcode try logging in with any Apple account.

Answer 5

A lot of talk here about exempting Xcode-beta.app from Gatekeeper, but for me, I had to make the .xip file exempt.

I placed Xcode_8_beta_6.xip into /Applications, then in Terminal, changed directory to /Applications and ran:

xattr -d com.apple.quarantine Xcode_8_beta_6.xip

Then double clicked the .xip to get it to unpack.

Just wait for process to get over with.. sometimes it takes longer than the usual time but ends up showing the alert boxes for next process! sit back let it finish. :)
