How to force quit applications on your Mac when app not responding
Mac has been a wonderful operating system as you get to work on many things on it. Working on a stable Mac device is really unique but unfortunately not all Mac app is stable and you get stuck on them and cannot do anything. Like clicking an open window doesn’t do anything, no matter what you try. Sometimes the Dock indicates an application is open, but you can’t seem to find or open any windows.
So if you get to know that Mac app is not working then there are ways to force quit them
Use the Force Quit Menu
First go under the Apple logo in the menu bar to open the force quit window or open this window by pressing Command+Option+Esc.
The Force Quit menu is a simple window, floating above all of your windows, with a list of currently running applications.
To force any application to close, click it in the list, then click the “Force Quit” button. In almost all cases, the application in question will close immediately. Applications that are totally crashed will sometimes have the word “Not Responding” in red next to the name.
This means macOS is aware the application is having problems. Now, you can force quit such applications just as easily as any other: just select it, then click Force Quit.
When an application is not responding, you can also force quit it using the Dock. Just right-click the icon and you’ll see that “Force Quit” has replaced “Quit.” This is occasionally useful, but for the most part it’s easier to just launch the Force Quit tool.
Use the Activity Monitor
The Force Quit tool is simple, but you can also forcibly shut applications down using the Activity Monitor. Unlike the Force Quit tool, you’ll see every process running on your Mac. You’ll also see how much CPU, memory, and energy they’re using up. This is useful if you suspect an application is bogging down your machine, but you’re not sure which one.
To force quit an application using the Activity Monitor, first select it in the list. Next, click the “X” button at top-left.
You’ll be asked if you’re sure you want to force quit the application.
Click “Force Quit” and the application should close instantly. The “Quit” option, which is the default, probably won’t work to close an application you’re having trouble with: it triggers the same close command you see when you left-click a desktop icon, or use the Command+Q keyboard shortcut.
Now follow the above ways and see how your apps on Mac that have been stopped working quits and goes away.
