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