Make Mission Control Feel Snappier [OS X Tips]



Yet another new feature in Mac OS X Lion, Mission Control transitions with an animated shrinking and growing of the current Space, showing all the other Spaces and open app windows for easy control over all the display options. If you feel like this transition could use a bit of a speed boost, try this easy tip.

To speed things up, simply open Terminal, and type or copy/paste the following:

defaults write expose-animation-duration -float 0.15

Then use the by now familiar restart Dock command:

killall Dock

Launch Mission Control from the Dock for with a three fingered swipe (enabled in System Preferences) to see the difference. If you want a shorter animation speed, use a smaller number after the -float flag, like 0.1 or so. You could potentially slow it down with a number bigger than the default (probably .2 or .3), but why would you want to? You’re all about productivity, baby!

Want to disable the transition altogether? Well, it’s your choice, so go ahead and use 0 for your -float flag, like so:

defaults write expose-animation-duration -float 0

Remember to restart the Dock and the transition will be gone, making for one oddly disturbing insta-Mission Control. Want to put it all back? Use this handy-dandy all-in-one Terminal command:

defaults delete expose-animation-duration; killall Dock

The end! A big thanks to the fine folks at OSXDaily for this one.

    I think one would have to be extremely OCD to do this. I mean, it takes what, .5 seconds for the animation? It’s not like one is stuck on a loading screen and waiting for mission control. Cool tip, but somewhat useless.

    great tip!

    Please, does anybody know how to speed up or switch off the animation of going to (back from) the full-screen mode? The default 1s is killing me.

    Please, does anyone know a shorter way of commenting on a web site.  The default (2 seconds) is *killing* me.  I just won’t SURVIVE if I can’t shave point 5 seconds off of my posting time.  The Horror!
