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
I had same issue. Quick fix is to open terminal from application or type terminal in spotlight and enter below command.
cd /Applications - This will move to applications directory where Xcode is present
xattr -d com.apple.quarantine Xcode.app - This will bypass Gatekeeper in OS X and will launch Xcode quickly
Note: If you have changed name of Xcode (say Xcode7-1) then you should enter ... Xcode7-1.app command. Refer screenshot
