If your Mac is frozen, slow, or otherwise won't allow you to restart when you want it to (and nothing else works), then you can force shut it down and restart it. When you restart, you will lose any data that was not manually or automatically saved.
Note! If a program is frozen and not responding, you can use the keyboard shortcut Command+Q and close the application (so as not to restart/turn off the computer).
It is better to wait a little before closing a frozen application. It may be that this application is trying to process your last request. The cursor in this case looks like this.
Important! If your Mac does not respond to anything and is frozen because nothing helps, not even hotkeys, then you will have to resort to a hard restart or emergency shutdown.
To do this, hold down the Power button for 5 seconds until your Mac turns off.
Press the power button to turn your computer back on.

A pop-up window will appear in which you can select the frozen application and confirm closing it with the “End” button.
