Apple - Can't disable "Press the Option key five times to turn Mouse Keys on and off"

Change the value of useMouseKeysShortcutKeys to NO in 'com.apple.universalaccess.plist'. I believe you will find the files in ~/Library/Preferences/. When you're done, don't forget to reboot ;)

Also, you can do this via Terminal by typing defaults write com.apple.universalaccess useMouseKeysShortcutKeys NO and pressing enter. You may need admin rights to do this.


There's indeed an option to disable that permanently
