I just installed Xcode beta, and when trying to open it, it stays on "Verifying Xcode.app" and does not proceed. Why is that? I have the latest OS X mavericks.

  • You may try to get rid of extended attributes with: xattr -cr /path/to/Xcode.app – Mateusz Szlosek Oct 8 '14 at 8:45

Open terminal and run below commands

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

This will bypass Gatekeeper in OS X and launch Xcode quickly.

  • This doesn't work for me as I don't have Xcode.app to begin with. I get: xattr: No such file: Xcode.app – micahblu Aug 24 '16 at 23:50

You said you are stuck with Xcode beta. Then the command will be

xattr -d com.apple.quarantine /Applications/Xcode\ Beta.app

0

It seems there's a global switch for the verifying in com.apple.LaunchService.

❯ defaults read com.apple.LaunchServices{
    LSQuarantine = 1;
}

❯ defaults write com.apple.LaunchServices LSQuarantine -bool NO

❯ defaults read com.apple.LaunchServices
{
    LSQuarantine = 0;
}

It should take effect after a rebooting.
