It is a uncommon event that I discover a MacOS app goes awry, nevertheless it does occur. When an app stops responding on the MacOS desktop, there is a user-friendly GUI instrument that may assist you to. Go to the Apple menu, click on Power Stop, discover the app in query, and Power Stop.
Nevertheless, that trick would not at all times work. On a number of events, I’ve found the Power Stop app refuses to do the job. When that occurs, most individuals would most likely flip to the restart possibility.

However do not do this — there’s a greater means. As a result of MacOS may be very a lot grounded in Linux, you may have the facility of the command line at your fingertips. That energy offers you the last word management over these apps, such that you could ship them packing with impunity.
There’s two instructions that I will present you how one can use. Upon getting the hold of those two instructions, you will by no means run into an app that you simply can’t shut — regardless of how cussed it’s.
Let’s get to it.
Finding the app identify
What you will want: The one factor you will want for this job is a laptop computer or desktop working MacOS. It would not matter which, nor does it matter which model of the OS you might be utilizing. I might, nevertheless, advocate you replace MacOS to the newest model supported by your {hardware} and maintain it updated always.

With that public service announcement out of the way in which, let’s get to the app-closing trick.
The very first thing to do is click on the Launchpad icon in your dock, find the icon for the Terminal app, and click on it.

Additionally: How to quickly fix Apple Mail when it’s not working
Understand that Linux instructions are case-sensitive, so we’re not on the lookout for mail, we’re on the lookout for Mail. What we will do is use two Linux instructions, ps and grep, to record all cases of working apps that embrace the phrase Mail. The command for this job is:
For many who wish to know, this is the breakdown of the command:

From that itemizing, we now know the app is, actually, working below the identify Mail. We will use that identify to kill the appliance. The rationale why we wish to confirm this identify is to not solely guarantee we have now the proper identify, however to ensure we do not unintentionally kill an app we want working that may have an identical identify.
We’re now going to kill the Apple Mail utility with the killall command, which is finished with:
It’s best to now discover that Apple Mail has been pressured closed, even when the Power Stop app didn’t work.
A phrase of warning
Solely use this course of if you find yourself sure the Power Stop app is not going to work and when the identify of the app you wish to kill. Do not go randomly utilizing the killall command on something that is working since you might trigger issues along with your OS or lose information. Use killall properly and it’ll function a serving to hand earlier than it’s a must to flip to rebooting.
