If one of your Mac apps freezes, the first thing you should do is just give it a minute. This way you give your computer a chance to come to its senses, and you don’t risk losing unsaved data.
If waiting doesn’t help, this is how you can force quit your Mac app:
- Shortcut: Option + Cmd + Esc to hit up the Force Quit Applications window. Now click on the frozen app icon, and hit the blue Force Quit button.
- Manual: go to your top left menu, click on the Apple icon > choose Force Quit > select the frozen app, and hit the blue Force Quit button.
If the above doesn’t do the trick, I published a more extensive tutorial on how to force quit Mac apps.
