The latest MacOS is the fastest operating system yet to be enrolled by Apple. But as with previous MacOS, High Sierra works well just until you open too many apps simultaneously, which can lead to an app failure. Most of us have encountered similar instances when the app doesn’t respond to any commands. Also, many of us know how desperate it is to be in a situation like this because there’s not much we can do to fix it.

Sometimes the app becomes completely unresponsive, and even the mouse cursor refuses to hit the quit button. That’s when everything seems to be a total disaster. But we’ve discovered some ways that can get you out of this mess. Read below!

Use keyboard to quit an app on High Sierra

Does your mouse cursor also fail you? Well, least of all should you worry. In case the mouse pointer gets frozen on the screen with your unresponsive application, the keyboard is the key to successful unlocking. If you need an application tab to disappear, just press and hold Command-Option-Escape.

After, you’ll see a window pop up on the screen with all applications currently running. So, to quit an app, you should select it from the list and then click the “force quit” button. This is the most comfortable option to force quit your app if something goes wrong. Just remember a simple combination above.

Force quit from the dock

It’s common for the upper menu bar on Macs to stop responding along with the application, leaving no options to click the quit button. And since just a minority of us really has time and patience to wait until the app becomes responsive, there should be a quick way out for the rest.

Fortunately, the dock on the lower screen can help you exit the app, reopen it and get back to work just in a matter of seconds. Simply find your app in the dock bar, then press the Option key and right-click, after, snap the Quit button at the bottom. That’s it. You’re good to use it!

Try the activity monitor

To use this hack, you should open the Activity Monitor first. To do this just click the Spotlight icon at the top right of your screen. When the search tool appears, type in “Activity Monitor,” and wait until the task manager is opened to sort out the app.

Ultimately, the task manager knows everything about your Mac and has access to all files and apps stored on the computer. Once you have it opened, click the “Force a Process to Quit” button on the top left side and then press “Force Quit” or “Quit.”

Force quit using the terminal

First of all, launch the Terminal by opening the Applications folder, and then “Utilities” just down below. It can take some time to process, but after a while, your username and a tilde mark will appear in the text box. There, type “ps -ax” and press the Return key to see all running applications. After, you’ll need to find a “PID number.”

Now you can command Mac to shut down a running app. Just enter the words “kill PID number, ” and your troublesome application will close immediately. However, this command will also force other apps to shut down so it might be reasonable to do this only if you are not worried about losing the data. Use this method only if it’s necessary since forced quit of an app is usually unsafe on Mac.
