Find the program you want to close. Underneath the column titled “COMMAND”, find the name of the app you want to disable.
- The COMMAND list can use the shortened name of the program. Look for a name that looks similar to the program you want to close.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/61/Force-Quit-an-Application-in-Mac-OS-X-Step-16-Version-3.jpg/ v4-728px-Force-Quit-an-Application-in-Mac-OS-X-Step-16-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/ 6/61/Force-Quit-an-Application-in-Mac-OS-X-Step-16-Version-3.jpg/v4-728px-Force-Quit-an-Application-in-Mac-OS-X- Step-16-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output “></div>”}
Find the PID number (Process ID – the code identifying the process you want to stop). Once you find the program name, look at the number just to the left of the program, below the PID column. Then write down this code.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e8/Force-Quit-an-Application-in-Mac-OS-X-Step-17-Version-3.jpg/ v4-728px-Force-Quit-an-Application-in-Mac-OS-X-Step-17-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/ e/e8/Force-Quit-an-Application-in-Mac-OS-X-Step-17-Version-3.jpg/v4-728px-Force-Quit-an-Application-in-Mac-OS-X- Step-17-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output “></div>”}
Type “q”. This command will exit the list of applications and return you to the command line.

Type “kill ###”. Replace the “###” signs with the number you just specified from the PID column. For example, if you want to close iTunes and the program has a PID number of 3703, you would type “kill 3703”.
- If the program does not respond to the “kill” command, type “sudo kill -9 ###”, replace the ### sign with the PID number. [1] X Research Source

Exit Terminal. The application will close and restart by itself.
Advice
- You cannot force the Finder application to shut down. If you select Finder, the “Force Quit” button will respond with “Relaunch”.
- Before clicking “Force Quit”, check again if the application still crashes. Sometimes the application will return to normal when you open the “Force Quit” window.
Warning
- Forcing a running program to shut down can cause you to lose unsaved changes to that program.
