Mac OS X has a fantastic feature that enables you to play window effects in slow motion by holding down the Shift key while playing the animation (like minimize, maximize, Exposé, etc...)

As a matter of fact, I don't like it! :)

How can I disable it?

Cool - didn't know about that. And +1 for asking in a positive way. –  Andrew Grimm Feb 10 '11 at 11:44

1 Answer 1

Open up Terminal.app


defaults write com.apple.finder FXEnableSlowAnimation -bool false

If you want to go back, use:

defaults write com.apple.finder FXEnableSlowAnimation -bool true

You'll need to restart the Finder after running the command.
