In Lion there is an animation when switching to and from full screen applications. Full screen apps are great, especially on a 11" screen, but this animation is getting very annoying. Is there a way to turn off these animations?

    Can we reopen the question now that it's officially out? – daaku Jul 20 '11 at 21:29
  • We are not re-opening Lion questions that were asked before the official release. – Philip Regan Jul 20 '11 at 22:40
  • Apparently there is re-post prevention logic and it's smart enough to not allow another question with only minor differences. Can you reopen this? – daaku Jul 22 '11 at 0:16

    Done. Good luck! – Philip Regan Jul 22 '11 at 0:53

There is, at least, a way to speed them up with a SIMBL bundle: http://www.yllier.net/SUFSA.html


No..for now there is no way to turn it off. I also want to turn to the annoying animations when a new window appears.


You can disable the system-wide animation for opening new windows in Lion.


Turn off zooming windows

Open Terminal and type the following:

defaults write NSGlobalDomain NSAutomaticWindowAnimationsEnabled -bool NO

    This doesn't impact the animations when an app is in full screen mode. – daaku Aug 14 '11 at 5:01

    This will not affect the animation the Dakku is asking about. It only disables a very subtle animation that occurs when a new window is opened. It also does not require a reboot to take effect. Simply run the command like this: defaults write NSGlobalDomain NSAutomaticWindowAnimationsEnabled -bool NO; killall Dock – Samuel Mikel Bowles Sep 30 '11 at 18:57
