Macs are known to have fast and stable systems. However, speed and stability aren’t a guarantee that Macs won’t misbehave from time to time. Sooner or later, Mac systems will slow down, hardware will retire, and apps will crash, all caused by everyday wear and tear and age.
Now, when Macs experience problems, it is likely that a huge number of Mac users won’t know what to do, as they are already accustomed to using their machines without any problems. If you are among these Mac users, fret not because we’re here to help.
Common Mac problems, especially those that have something to do with speed, can be quickly fixed by simply restarting the system. But issues that involve error codes like the CryptoSwift.AES.Error.invalidData and SystemExtr may require more than just rebooting the system.
What Are CryptoSwift.AES.Error.invalidData and SystemExtr Errors?
The CryptoSwift.AES.Error.invalidData and SystemExtr errors surface when there are problems with the system files or the hardware, causing apps to crash or the system to reboot itself.
Here are some possible causes of the errors. Perhaps you have unintentionally downloaded and installed a program, which comes with malicious files and malware. As a result, some of your system files get corrupted and messed up. Maybe your newly downloaded program is also incompatible with your software or drivers, hence causing your system to quit unexpectedly.
Regardless of what’s causing the CryptoSwift.AES.Error.invalidData and SystemExtr errors to occur, we’ve got your back. We’ll teach you how to fix the SystemExtr error that causes apps to crash or quit unexpectedly on Macs.
1. Force-Quit the App.
While in the middle of work, an app you’re using might hang or freeze. A few seconds later, the dreaded spinning beach ball appears, which indicates that the app is no longer responding.
In these instances, all other active apps will continue to function, because the spinning beach ball only shows on the window of the unresponsive app. To solve the problem, you have to quit other unnecessary apps to free up your RAM and give way for more valuable tasks. Here’s how:
- Bring an app to the foreground.
- Open the menu and select Quit. You can also use the CMD + Q shortcut key.
- If the app is stuck and the traditional Quit command does not work, navigate to the Apple menu and select Force Quit.
- Choose the stuck app and hit the Force Quit button.
2. Reboot Your Mac.
Rebooting your Mac can quickly resolve problems related to apps. To reboot your Mac, follow these steps:
- Go to the Apple menu.
- Click Restart.
- Your macOS should now quit all active and background apps, freeing up your CPU and RAM.
- If you can’t access the Apple menu because your system is frozen, press the CTRL + CMD keys while holding the Power button. This should initiate a force restart.
3. Install Software Updates.
If an app is not working properly, you may need to download and install any available updates. To do this, follow these steps:
- Open the App Store.
- Go to Updates.
- Click the Update button next to the unresponsive app.
4. Check Any Compatibility Problems.
Another way to fix your problem is to check if your apps are compatible with your current macOS version. Although it sounds like a technical solution, it quite isn’t. Simply follow the instructions below and you should be on the right track:
- Open the Apple menu.
- Select About This Mac. Check the current macOS version you are using.
- Now, check the system requirements of the app. Visit the official website of the developer of the problematic app and search for its system requirements. Compare it with your system requirements and see if there is any mismatch.
5. Run a System Scan.
Sometimes, junk files created by apps and browsers interfere with your system, resulting in errors appearing. That means getting rid of such files may prevent errors from surfacing and apps from crashing.
To run a system scan, you can use reliable system scanning tools for Mac to pinpoint junk files and delete them.
6. Clear the Cache.
All Mac apps have cache files. These files store frequently used information that helps the apps run smoothly and more efficiently. But if a cache files becomes corrupted, then an app crash may occur. Your macOS can remove the corrupt cache, but since it is hidden, your system might not be able to locate it.
In most cases, the cache files are located in the Library > Cache folder. It is conventionally named based on an app’s name, so you should be able to identify it immediately.
To clear any corrupted cache file, do the following:
- Quit the problematic app first.
- Look for its cache file in the location specified above.
- Once you have found it, drag it to the trash bin. When you open the app again, a new cache file will be generated automatically.
Take note, though, you must not clear out caches if you are uncertain, because these files are responsible for keeping your Mac’s performance smooth. Deleting them indiscriminately will cause your computer to rebuild them, which will take time and may potentially trigger more errors.
One of the solutions above should fix your CryptoSwift.AES.Error.invalidData and SystemExtr-related problems. But if none of them worked, it is best that you contact Apple’s support team, or take your Mac to the nearest Apple store and have it checked.
