Pressing these three keys simultaneously will bring up the “Force Quit Applications” window on Mac OS X and allow the user to choose the specific application to force quite.
Often times, if an application is not responding, it will say so in parenthesis next to the application’s name in the “Force Quit Applications” window.
If a user wants to stop specific process on Mac OS X, they can using a built in OS X utility called “Activity Monitor”. This application is available inside of the Applications folder and the Utilities folder on all computers running OS X.
As shown in the video, using this application, users can select specific process to kill on their computer instead of force quitting entire applications.
