Troubleshooting the 'Kernel Panic' Issue on Mac
Mac systems are known for their stability. However, users may still encounter an issue known as 'Kernel Panic.' What this means is that the Mac has encountered a critical issue it can't resolve. The screen will go black and then a warning message stating that the computer needs to be restarted will be displayed. This message is the factor the separates a 'Kernel Panic' problem from a usual Mac restart or an application crash. The closest analog on a Windows system is the 'Blue Screen of Death.'
The causes of a 'Kernel Panic' are myriad but they can be split broadly into hardware and software issues. Fixing hardware issues in your home can be nigh impossible and is best left to technical specialists. However, Dealing with the software side of things is a different matter, and there are several quick and easy solutions that might be able to help.
- Check for software updates
Open the App Store application via either Spotlight or the Apple menu. Then go to the App Store and click on 'Updates.' The latest updates available for your Mac should appear. Install them to fix any potential compatibility issues with older tools.
- Remove corrupted applications
If you have noticed that the 'Kernel Panic' problem appears when a specific application is launched, then it must be the cause. Remove the application, if possible, and check whether the Mac will experience the problem again. You also can uninstall it completely, reinstall the application, and then fix any files that might have gotten corrupted.
- Running low on free space
At least 20% of the space on your hard drive should remain free, Apple recommends. If that threshold is passed then the system could begin to experience general instability and various issues may arise. To check how much free space you have on the system, go to the Apple menu and select 'About This Mac.' Now, switch to the 'Storage' tab. If the main volume of the system is close to full capacity, you may need to free up some space by deleting unnecessary applications, movies, photos, backups, etc. Users can also take advantage of the built-in Apple tools designed to help with this particular task by clicking on 'Manage.'
- Try the Launch Disk Utility
'Kernel Panic' also can be caused by corrupted files or problems associated with external devices. If that is the case then the Disk Utility and more specifically its First Aid tool, that comes with the macOS could be helpful. It is designed to find and resolve potential disk errors.
To start the process you will have to restart the Mac system. While the machine is booting, press and hold the Command+R buttons on your keyboard. This should open Disk Utility. From the available options choose First Aid and follow the on-screen instructions.
