I was recently experiencing some heavy crashing on an OS X 10.7.4 Mac. For some reason, any time I would try to use Quick Look, the Finder would crash. Most apps would crash on launch - it was incredibly frustrating! I first did an NVRAM reset and then repaired permissions but the problem still persisted.

As Mac OS X users, we have something to be happy about when it comes to app crashes and freezes: rarity. Typically you can work on your Mac for hours at a time without a single issue. However, a crashing app certainly can happen, leading to lost productivity, time and, worst of all, lost work. Fortunately, there are several steps you can take to recover from a crashed app, as well as prevent the issue in the first place.

How to fix a crashing app after the macOS upgrade

App crashes after the the macOS update is more than a common problem. Some apps freeze or malfunction, some won’t launch, some show no signs of life whatsoever. Why it happens? The most probable reason is that the app is simply not ready for the latest macOS Catalina. Something in its depth turned out to be incompatible with the new macOS.

Now, what can you do to fix an app crashing? Three things.

1. First, see if you have the latest version of the app by clicking on its name it the top menu and choosing Check for updates.
2. Second, visit developer’s website (or App Store page) and see if they’ve issued a statement about Catalina compatibility.
3. Finally, some crashed apps on macOS Catalina can be fixed by running maintenance scripts. Download CleanMyMac X, launch it, find Maintenance tab and run the scripts.

What happens when an app craches: under the hood

Now let's go deeper into the nature of crashed apps, but first, let’s identify the difference between a crashed macOS app and a frozen one. While these terms are often used interchangeably, there is a notable difference.

Crash

A crash happens when a piece of software stops working altogether, and then closes on its own. In other words, the app quits when you did not tell it to. When this happens, you'll typically see a message noting that the application has 'unexpectedly quit” just as its windows disappears. It’s pretty frustrating — especially if you end up losing all your work.

Freeze

A freeze is when software stops functioning, but continues to run. You can still see its windows, and its Dock icon still indicates that it’s running. However, no amount of clicking or tabbing around will do anything. A frozen app doesn’t quit like a crashed app does, it simply becomes unresponsive. Often no error messages accompany the freeze. Again, it’s a frustrating experience (if you want to know how to deal with it, check out this post on how to fix frozen apps).

When software freezes, you force it to quit, so that you can re-launch and hopefully get on with your work. With crashes, meanwhile, the problem is the app quitting on its own. In this article, I’ll discuss recovering from app crashes, as well as steps that help prevent them in the first place. Let’s get started.

What to do when a Mac OS X app crashes

The good news here is that a crashed app rarely brings down your entire Mac, as the trouble is restricted to that particular piece of software. That means we have a chance to recover. Let’s start with the simplest solutions.

First, just relaunch the app. When an app crashes, you’ll typically see a dialog box that says the software “unexpectedly quit” and you’ll have several options to deal with it, including “Relaunch”. Give that a click and cross your fingers that the crash doesn’t happen again. Oftentimes, you’re good from there. If not…

Try restarting your Mac. “Turn if off and back on again” is almost a punchline at this point, but it usually works. Shut down, restart and try again. Very often this simple task will set things right. If not, it’s time to try something just a little more involved.

Reinstall the app. Deleting the misbehaving app and grabbing a new copy gives you a fresh version to work with. That is, if you delete all of the app’s related files.

See, when you drag an app to the Trash, you aren’t deleting everything. Some leftover parts remain, and if the troublemaker is among them, your problem could persist. It’s a waste of time to delete an app via drag-and-drop, reinstall and then have it crash again. To make things right, you need to get rid of the app’s bits and pieces before you reinstall it, and this is where software like CleanMyMac X comes in handy.

An app that’s simply dragged to the Trash leaves behind a pile of associated files that you don’t see, like caches, preferences (often the culprit in crash-y apps), saved states, and more. You might not even know they’re there, but CleanMyMac X does. It’s smart enough to find the whole lot, safely remove them, and ensure that a newly installed app is just that: a complete fresh start.

In fact, you don’t even have to launch CleanMyMac X to thoroughly and safely delete an app. Simply right-click (or Control-click) the app’s icon and select “Uninstall with CleanMyMac” from Services in the resulting contextual menu. Easy!

Another wise move is to make sure there are no conflicts between the app and the Mac OS. When Apple pushes an update of its operating system to your Mac, that might interfere with your app’s performance, if the app or its add-ons are incompatible with this particular OS X version.

CleanMyMac can help you out here, too. Download it for free, go to its Uninstaller module and find the misbehaving app in the list. If you see a note that this app is incompatible with your system, it means you need to update the app, because your current version doesn’t work on the latest OS X.

How can you stay on top of aging apps? Apple makes it easy with software purchased through the Mac App Store. Simply launch the App Store app, go to the Updates tab, and you’ll see all available app updates. Find the one you need in the list, click the Update button, and you’ll get the latest version to your Mac. It’s a bit different with software acquired outside the App Store: you’ll have to visit the vendor’s website to see if there’s a new version available.

If nothing indicates that the troublemaker app is incompatible with your system, the problem could be with its add-ons or preferences. What you can do in this case is reset the app to its initial state. Again, go to the Uninstaller module in CleanMyMac X, select your app, and click Application Reset. CleanMyMac will make that app just the way it was when you first installed it.

What to do when an app crashes at launch

So far I’ve addressed what to do when an app crashes as you’re using it. But what about the frustrating scenario of an app going down as soon as you launch it? No warning, no dialog box, just a bounce or two in the Dock and that’s it. In this case, it’s time to repair disk permissions.

What’s does fixing permissions actually mean? Think of your Mac’s hard drive as a tree with many branches. The top level of your drive is the tree’s trunk, and the branches represent information about files and folders. These branches, or “nodes,” store information like the location of data and permission rules, among other things. Normal computer use changes this information, and can lead to a conflict or other issue that generates crashes and the inability to use your system. This is what a permission fix addresses.

How To Stop Apps From Crashing

To repair disk permissions (for OS X prior to El Captian), go to the Utilities in your Mac’s Applications folder and launch Disk Utility. Next, click First Aid. It’ll ask for confirmation and get to work, comparing existing permission files with defaults to find any conflicts.

Or, if you want a slightly simpler way, you can fix the permissions with CleanMyMac X Maintenance Scripts. Just open the Maintenance tab, hit Choose Tasks and then Repair Disk Permissions. This helps resolve improper app behavior like crashing and keeps all of your disk’s files and folders in proper order. And that’s just one of the maintenance tasks available in CleanMyMac X, just try it.

A crashing app is no fun. Fortunately, a little understanding and proactive behavior can keep them to a minimum. CleanMyMac X makes it easy to do just that. Happy computing, and may your apps never crash again!

Why Does My Photos App Keep Closing

Does your Mac keep freezing and stop responding, randomly and unexpectedly? There can be a number of reasons that can cause your Mac to become unresponsive to any user input from the keyboard or mouse or to freeze altogether. By freezing, it is meant that nothing happens. Sometimes you may start having this problem after updating to the latest version of the macOS software.

This article explains what you can do when your Mac freezes and stops responding, meaning how you can unfreeze your Mac. This can be a big issue if this occurs frequently. If you are having this problem, then you can troubleshoot using the steps listed below. So what causes freezing? You should know this so that you can fix it.

If your computer is crashing, you may use Crash Reports to figure out why.

Unfreeze your Mac

Before you do anything, give your Mac a few minutes to finish what it is doing. Your Mac may unfreeze itself if you wait a few minutes.

If your Mac freezes, an unresponsive app may cause your Mac freeze. You may have to force quit apps that are not responding to unfreeze your Mac. Here is how:

• On your Mac press the Option, Command, and Esc (Escape) keys together
• This will open the Force Quit window
• Select the unresponsive app and then click Force Quit
• Did your computer unfreeze?

If the force quit option does not work, try to restart your Mac by going to the Apple menu > Restart.

If this option does not work, you can force your Mac to restart by pressing and hold the power button until your Mac shuts off (note that you may lose any works that are not saved).

If your Mac freezes frequently, you should figure out why your Mac is freezing. Here are the most common mac slow and freeze reasons and fixes:

Software-related problems

Update your Mac. Make sure that your Mac is completely updated, this includes the third-party apps. Update macOS and all apps:

• Go to the Apple menu > System Preferences > Software Update. If there is an update available, update your Mac.
• Open the Mac App Store app > then click Updates (left menu) and click Update All

Furthermore, restart your Mac in safe mode for Symptoms.

• Turn off your Mac
• Turn on your Mac and immediately press and hold the Shift key
• Keep holding the keys until you see the login screen, and then release the keys
• Log in using your username and password, you may have to log in more than once.
• Now your computer is in safe mode.

If the symptoms exist in safe mode, please continue the steps below.

Too many open apps

Another common cause is running out of free memory if you are running multiple apps at the same time. Furthermore, quit apps when you are done with them. To quit an app, click the App name and then click Quit App, for example, if you want to quit Safari:

• Click safari
• Click Quit Safari

You may also want to use Activity Monitor (Applications / Utilities) to find the apps and processes that are using a lot of resources. And then you may choose to quit them in Activity Monitor.

Not enough space

Your Mac can freeze if there isn’t enough open space. To check your Mac’s free hard drive space, go to the Apple menu > About This Mac > and click the Storage tab. Click the Manage button to optimize your storage. You may also consider emptying your Trash can. You may also use iCloud.

There are many tips that you can try to free up space on your Mac.

Overheating

One common reason is that it’s overheating, especially if you are having this problem with a MacBook. Check air vents. Blocked air vents can cause not only performance issues but also system freezing problems. Check the vents on your Mac to see if they are blocked with dust or dirt. Make sure that vents are allowing heat and air to pass through so that your Mac does not overheat.

We previously wrote an article about the overheating problem. Please read this article.

Malware

Check for malware. Malware or malicious software (viruses, spyware, etc.) can cause your Mac to freeze or appear to hang. We previously wrote about these topics:

Cluttered desktop

A cluttered desktop can slow down and/or freeze your Mac. Organize your desktop. Delete files or folders that you do not need. macOS offers a feature for this called Stacks. Turn on Stacks on your Mac (if your Mac is running macOS Mojave or later). Here is how you can enable Stacks on your Mac:

• Go to Finder
• Click View (top menu bar)
• And select Use Stacks
