How to Force Quit an App in Mac OS X

Force quit apps that aren't responding

Sometimes your Mac can get overloaded and applications will freeze up and stop working, but they stay running. When this happens, you can use the Force Quit function to turn these applications off. To Force Quit an app:

1. Hold down Command-Option-Escape at the same time. This opens the Force Quit window and you can choose the app to quit. This is a good key combination to memorize, in case your mouse locks up along with the app.
