Windows like Ctrl + Alt + Delete on MacOS App To Kill Tasks

last updated in Categories ,

On Windows, I can hit Ctrl + Alt + Delete and kill apps or do other stuff. Sometimes Firefox browser hangs on macOS. Is there an equivalent of Ctrl + Alt + Delete keyboard shortcut to kill frozen apps on Apple macOS Sierra?

There is no all in one equivalent on macOS. Yes, if your app on Mac computer stops working and you cannot quit the app such as Firefox generally, use Force Quit to close that app.

  1. cmd + alt (option) + [ESC] does the trick and lets you force quit applications or you can use Right Click (Ctrl + mouse click) the running application in the Dock and hold the Option (alt) key which also enables you to force quit an application.
