How to disable slow motion effect in Mac OS X (shift key)?

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?

Open up Terminal.app

Type:

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.

At least for me, in Yosemite 10.10.3, the following answer from our friends at Ask Different worked: https://apple.stackexchange.com/a/115698

You can disable the hotkeys for slow motion effects by following these instructions:

1. Open Terminal

2. Go to ~/Library/Preferences by typing cd ~/Library/Preferences.

3. Write open com.apple.symbolichotkeys.plist and press Enter.

4. A window similar to this will open:

5. For items 34, 35, and 37, set enabled to NO.

6. Restart your system.

7. Enjoy.
