I believe it has happened to you - force quit is not working on your Mac in any way, whether clicking Force quit or using the Command-Option-Escape shortcut. It has happened to many commonly-used apps, such as, Safari or iTunes won't force quit. This passage is going to offer you three ways to fix force quit not working problem on Mac. You can force quit Safari, iTunes, Photos, Mail or other apps that won't quit.
- Way 1: Kill Mac Process

If you cannot quit an app with force quit or Command-Option-Escape, you can turn to Activity Monitor, which allows you to force quit any frozen apps.
Step 1 Open Activity Monitor in Application > Utilities.
Step 2 Find the app that won't quit in the process list and select it.
Step 3 Click the X button in the upper-left corner.
Step 4 Click Quit first. If the app still won't quit. CLick Force Quit.
If force quit in Activity Monitor is still not working, you can force quit the frozen app with a command line method, which means you can quit an unresponsive app through Terminal. Here are the steps:
Step 1 Open and run the Terminal.
Step 2 Type the command: killall [application name]. For instance, if iTunes isn't responding, type killall iTunes.
Step 3 When you are ready, click Enter. As soon as you click it, your application will be shut down in time.
You can also force quit an app on Terminal using the app's Process ID (PID)
Open a new Terminal window and enter the command: top -o cpu. Then a list of all running applications and processes will appear in Terminal with the app's process ID. Take down the PID of the app that cannot quit.
Then open a new Terminal session, type: kill [PID]. FOr example, if iTunes won't quit and its PID is 1234, type: kill 1234 to force quit.
Note: The PID of an app will will change each time the app is launched.
