How to Force Quit a running App on Mac

For the most part, the Mac is a very stable computer system. But sometimes, an app does lock up and you cannot quit it normally by using [COMMAND]+[Q] key combinations.

Fortunately, Apple has made it easy to quit an offending application. Here’s how:

  1. Click  > Force Quit. 
  2. A window will open showing all of the currently running programs.
  3. Click on the app that’s locked.
  4. Click the Force Quit button on the lower-right of the window.
  5. That’s it.
