Ok, I get it. There is no equivalent to the PC’s Ctrl+Alt+Del shortcut on a Mac® to force quit an application. So how do I quit that annoying program that’s not responding?

How to Close a File on a Mac. Apple's Mac OS X is similar to the Windows operating system in form and function, but with the release of 10.7.5 Lion, Mac OS began changing its computer operating system to act more like a mobile operating system. The other answers are correct, but — we’re talking about Macs here, not Windows boxes — there’s really no compelling reason to quit an app you won’t be using for a while.

Luckily, Apple® has you covered and gives you multiple options. The shortcut actually exists, and moreover, there are a few other extremely convenient ways to fight buggy apps. Today I’m going to list three easy ways to force-quit an application on a Mac, without harming the system.

Let’s dive in!

Is it Safe to Force Quit?

Forcing a frozen application to quit is the same as killing the symptoms when we get sick versus curing the virus. We need to see the bigger picture and understand what causes the problem and how to cure it while understanding how to avoid it from happening again.

The number one reason we have a problem with frozen applications in a Mac is insufficient RAM—or, in other words, a lack of computer memory to operate the system compared to the number of applications you usually open (including those numerous open tabs in a browser). So anytime your system utilizes all of its existing resourses to run the task, it becomes unresponsive. Think of RAM like a physical workbench. The more space (memory) you have to work, the more projects you can have out to work on. Less space? Less ability to work on multiple things at once.

Forcing Mac to quit the application does resolve the problem but may have downsides. When you close an application in the traditional manner, it will clean everything it runs in the background and alert you to save the work. When you force close on Mac, you may end up losing files and data, or mess things up on the drive. Although the effect will only be related to that one particular application that got stuck, sometimes it can hurt.

Using a smart app like Parallels Toolbox can help you to free up unused memory on the fly and prevent the applications from getting frozen over and over again. The package includes over 30+ useful apps for everyday needs that any Mac user will benefit from, including downloading videos and music from sites like YouTube, taking screenshot or record videos, optimize your Mac performance, free up extra space and so much more.

1. Force Quit Using the Apple Menu

The most conventional and effective way to close frozen programs is to go to the macOS® menu bar, located along the top of the screen in the Finder menu. Mac how to delete damaged incomplete apps.

To force quit an application, simply do the following:

1. Click on the black apple icon in the upper-left corner.
2. From the drop-down menu, select “Force Quit…”. You will be directed to the new window named “Force Quit Application” where all the magic happens.
3. Now all you have to do is select the application you want to close and choose “Force Quit.”

If you don’t know which application is stuck, pay attention to the ones that have the note “Not Responding.” This usually appears next to frozen applications.

2. Force Quit with Mac Shortcut

To do the same thing but faster, use Mac shortcut keys to close frozen applications.

How Do You Get Apps On Computer

1. On your keyboard, press and hold Command + Option + Esc. It will immediately bring up a “Force Quit Application” window.
2. Select the frozen application from the dialogue box and select “Force Quit.”

This could be your go-to method if the mouse or trackpad is lagging.

3. Close Application from Activity Monitor (Ctrl+Alt+Del Alternative)

Here’s the pinnacle of this article.

Very few Apple owners know that macOS provides an almost identical alternative to the traditional PC Control+Alt+Delete shortcut—and does it better. Yes, we all know that in Windows that keyboard shortcut is often used to open the Task Manager window. (To be honest, it’s needed too often, which is why we’re on a Mac.) From Task Manager, you can track applications, services, performance, and processes, and kill some of them when they’re unresponsive.

You can easily do all of that and more on the macOS native application called Activity Monitor.

To kill an application using Activity Monitor, do the following.

How To Force An App To Close On Mac

1. On your keyboard, press Command + Space, or click on Spotlight in the top-right corner of the screen.

2. In the “Spotlight Search” window, start typing “Activity Monitor.”

3. Once Activity Monitor is highlighted, hit Enter.

4. In the Activity Monitor processes list, select the application you want to quit and click “Force a process to quit” in the left corner.

What to Do If Force Quit Isn’t Working?

If all the applications stop responding and you can’t quit them using one of the methods described above, you can force your Mac to restart. To do so, press and hold the Control+Command+Power buttons.

Alternatively, you can force Mac to shut down by pressing and holding the power button, or use one of the many other shortcuts.

What’s the Solution?

Since your Mac doesn’t have enough space to run all those applications you need, the most obvious step would be to increase the RAM. If you own an iMac® or the older generation of MacBook Pro®, you can simply buy memory and upgrade your existing computer. With the new Mac generation, you don’t have that option anymore because the RAM is glued and soldered to the motherboard. You either buy a new computer or struggle.

Alternatively, you can clean your memory to free up space using Parallels® Toolbox. Parallels designed a tool set for macOS and PC users to efficiently manage their computer with just a few clicks—without any professional knowledge needed. Within the application (which is available to try for free), you can easily free up unused computer memory, clean your drive, and help your Mac run at max speed with a dozen other useful utilities.

If you’re interested in learning how easily one click can save precious disk space, check out how much space I took back with the Parallels Toolbox tool Clean Drive:

In one click (and about 10 seconds), I successfully removed 4 GB of clutter and reclaimed space on my hard drive.

So there you have it. Take care of your Mac with those quick tips, and remember to always save your work!

Imagine this: you’re working happily on your Mac when the dreaded beach ball of death appears. A program stops responding or worse, the macOS (or OS X) itself refuses to do anything but stare at you, blankly. You have a frozen Mac app or an OS X freeze. Mac OS not responding can lead to lost productivity or even lost work. Let's go over why it happens, what to do when your Mac freezes or when an Mac OS app stops responding, as well as some tips for preventative maintenance.

We’ll go over frozen apps first, so if your whole Mac freezes, you can jump to the part about fixing a frozen Mac.

Fixing a frozen app: Why Mac OS apps freeze

There can be a few reasons why apps freeze on Mac. First, sometimes an app freezes on its own, and sometimes it takes down the whole Mac with it. Here's what could be happening:

1. Apps freeze in the background.
   This could mean there are some apps running that you didn't open, they opened themselves. Probably, they're featured in your startup items, so they automatically launch when you start your Mac. If this happens repeatedly, you need to check what apps are running in the background and launch with the startup.
2. Processes freeze in the background.
   This one is different from apps. One app may be running multiple processes, also system processes can be running on their own.
3. Too many apps and processes running.
   Same logic as with the previous issue. But the question here is how many is too many? There is no definite answer to this, it very much depends on the hardware capacity of your Mac. You can read how to check it and fix it below.
4. Mac system is too cluttered with junk to run even simple tasks.
   This is fixable, you can get a Mac optimizing app like CleanMyMac X for the job. Run a scan to find and remove the stuff you don't need, and there's a high change your apps will stop freezing after that.

What to do if an app freezes on your Mac

A frozen app becomes unresponsive and brings your work to a halt. In the worst case scenario, it can lead to lost work or a corrupted file. Fortunately, there are several options to try, and most are quite simple. Here’s what you can do when a program freezes on your Mac. First, you need to quit it. Then, if the app keeps freezing when you launch it, try the next options.

How to quit a frozen or unresponsive program

Quitting and then re-starting an app is a good way for Mac OS to handle a crash. You can do this from the OS X Dock or from the Force Quit window. To force-quit an app from the OS Dock, follow these simple steps:

1. Click anywhere outside of the program
2. Right-click (or Control-click) on the frozen app’s icon in the Dock. A menu appears.
3. Hold down the Option key on your keyboard so that Quit in that menu changes to Force Quit.
4. Select Force Quit.

That’s it. The app is instantly closed. Re-launch it and try again. If you prefer to work with the Dock hidden — or if the Dock itself is unresponsive — you can simply bring up the Force Quit dialog box to perform the same task.
Here’s how:

1. On your Mac’s keyboard, hit the Option, Command and Escape keys simultaneously (alt + ? + esc).
2. The Force Quit dialog box appears with a list of running programs.
3. Select the frozen app and then click Force Quit.
4. The software will stop running and you’re free to re-launch it at this point.

If you’re using a maintenance utility like CleanMyMac X, it has freezes covered. When CleanMyMac spots an unresponsive app, a notification window with a Quit button pops up, so you could force-quit the app without rummaging around in its menu.

CleanMyMac keeps an eye on other performance issues, too, so if you'd like to get alerts like this one when anything goes wrong, download CleanMyMac X for free and give it a try.

First, check what apps are running in the background and launch with the startup.
To do it go to Settings > Users and Groups > Login items.
Uncheck anything you think might be causing trouble. In fact, just to be sure, uncheck every app and restart your Mac.

Now, find out which process or program is causing the problem. How to see what programs are running on Mac in general? You need launch Activity monitor.
How to find Activity Monitor on Mac: You can do it via the Spotlight Search or just open Launchpad and type it in.
How to open Activity Monitor in Finder: launch it from Applications > Utilities folder > Activity Monitor.

When it opens, you'll probably see hundreds of processes in each tab, but the ones you need now are CPU and Memory tabs. Click on the % CPU sign to sort processes by their influence on your Mac's work. The heaviest ones will show up on the top. They could be your main issue, but don’t rush to deal with them. Some, like kernel, are important system processes and you shouldn’t mess with them.

How to kill a process on Mac OS

However, sometimes your problem does lie within a specific process, you can force quit it (Apple doesn't call it 'to kill a process on Mac', they make it sound fancy). But we're not at Apple HQ, so here's how to kill a Mac OS process:

1. Open Activity Monitor.
2. You see a list of processes. You can sort them by clicking on %CPU or % Memory in relevant tabs.
3. Find the process you want to kill and choose it.
4. Click on the octagon with an X sign.
5. Done.

Occasionally the problem isn’t with the Mac app, but with the Mac OS itself. If you’re experiencing troubles regularly, it’s time to ask why your Mac keeps freezing. There are several possible reasons, so let’s start with the simplest potential solution.

First, the file you were working with at the time of the freeze may be the issue. To help determine if this is true, try opening a different file with that app and work with it for a while. If it behaves normally, quit and then go back to the file you were working with at the time of the crash. If the errant behavior persists, you may have found your problem. Salvage what you can into a new file.

Make sure that your software and OS X are up-to-date. This is easy to do with software purchased from the Mac App Store. The same goes for OS X. Launch the Mac App Store on your Mac, and you’ll see the list of pending updates, including any for the OS X itself. For third-party software purchased outside of the App Store, visit the manufacturer’s website.

What to do if Mac OS X freezes

If you cannot force-quit a program, or if the Mac OS is completely unresponsive, it’s time for the most obvious action — a reboot.
You can bring up the Restart/Sleep/Shutdown dialog box instantly by hitting Control plus the Power button. Option four, Shut Down, is selected by default.
Alternatively, you can press and hold the Power button for 1.5-2 seconds to bring up the same dialog box. If things aren’t hopelessly messed up, you’ll get a chance to save your work before your Mac shuts down. If that still doesn’t work, a more drastic option is available.

How to force reboot a frozen Mac

Press Command ?, Control and Power (on earlier MacBook models, use the Media Eject key instead of the Power button) to restart your Mac immediately. Note that you won’t have the option of saving anything in this scenario, but it will definitely reboot your icy Mac.

Once your Mac has restarted, you might find that the hard restart has corrupted the file you were working on. Salvage what you can from it and create a new file.

How to fix a frozen Mac

After the reboot, ensure that your Mac has enough free hard drive space for the OS X, and enough free RAM to do what you want. CleanMyMac X can help you here, too. It removes all the useless files that take up space on your hard drive: app leftovers, mail attachments, cache files, and so on. That way, you can free up additional disk space for the OS X without deleting any of your own files. Plus, CleanMyMac X keeps tabs on how much RAM you’re using and lets you free some up with a tap.

Finally, if system cleanup also fails to fix the problem, you can try to run a clean install of your Mac OS. Just follow the instructions: How to clean install macOS Sierra 10.12

Note: If you don’t know which system your Mac runs, click the apple icon in the top left corner and choose About this Mac. You’ll see the name on the popup window.

How To Close Apps On Computer

That’s it, we hope this guide has helped you fix a frozen Mac. Remember, with day-to-day maintenance, your Mac can offer years of reliable work. On the rare occasion of a frozen program or even frozen OS X, these tips will help get you working and productive again. And software like CleanMyMac X can do some of the monitoring and maintenance for you, so you can focus on what needs to be done.
