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. How to read all on mac email app. First, sometimes an app freezes on its own, and sometimes it takes down the whole Mac with it. Here's what could be happening:
- 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. - 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. - 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. - 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:
- Click anywhere outside of the program
- Right-click (or Control-click) on the frozen app’s icon in the Dock. A menu appears.
- Hold down the Option key on your keyboard so that Quit in that menu changes to Force Quit.
- 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:

- On your Mac’s keyboard, hit the Option, Command and Escape keys simultaneously (alt + ? + esc).
- The Force Quit dialog box appears with a list of running programs.
- Select the frozen app and then click Force Quit.
- 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.

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.
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.

There’s never been a better time to turn your iPad app into a powerful Mac app.
Designed for macOS Big Sur.
How To Demo App On Mac
When an app built with Mac Catalyst runs on macOS Big Sur, it automatically adopts the new design. The new Maps and Messages apps were built with the latest version of Mac Catalyst.
Get a head start on your native Mac app.
Your iPad app can be made into an excellent Mac app. Now’s the perfect time to bring your app to life on Mac. The latest version of Xcode 12 is all you need. Begin by selecting the “Mac” checkbox in the project settings of your existing iPad app to create a native Mac app that you can enhance further. Your Mac and iPad apps share the same project and source code, making it easy to make changes in one place.
Optimize your interface for Mac.
Your newly created Mac app runs natively, utilizing the same frameworks, resources, and runtime environment as apps built just for Mac. Fundamental Mac desktop and windowing features are added, and touch controls are adapted to the keyboard and mouse. By default, your app will scale to match the iPad’s resolution. On macOS Big Sur, you can choose “Optimize interface for Mac” to use the Mac idiom, running your app using the native resolution on Mac. This gives you full control of every pixel on the screen and allows your app to adopt more controls specific to Mac, such as pull-down menus and checkboxes.
Even more powerful.
The new APIs and behaviors in macOS Big Sur let you create even more powerful Mac apps. Apps can now be fully controlled using just the keyboard. You can create out-of-window and detachable popovers, control window tabbing using new window APIs, and make it easier for users to select photos in your app by using the updated Photos picker. iOS Photos editing extensions can now be built to run on Mac. And your app is even easier to manage when it’s running in the background with improved app lifecycle APIs.
New and updated frameworks.
Mac Catalyst adds support for new and updated frameworks to extend what your apps can do on Mac. HomeKit support means home automation apps can run alongside the Home app on Mac. The addition of the ClassKit framework lets Mac apps track assignments and share progress with teachers and students. Plus, there are updates to many existing frameworks, including Accounts, Contacts, Core Audio, GameKit, MediaPlayer, PassKit, and StoreKit.
