Your Mac may sometimes throw kernel panic errors when shutting down. Other users reported they encountered the same issue when waking their computers from sleep. This problem has been around for a long time and fixing it is not an easy task. Let’s take a closer look at the root causes of this problem.
Kernel panic errors are actually important safety measures. Your operating system decides to shut everything down after detecting fatal errors that could potentially lead to major data loss.
Software conflicts and incompatible hardware are two of the most common triggers for kernel panic errors on Mac. Outdated app and OS versions may also cause unexpected system glitches and trigger kernel panic errors.
Other reasons include not enough RAM, not enough free space on your hard drive, outdated driver versions, and conflicting system settings. Let’s explore how you can fix kernel panic errors on Mac.
A number of users solved this problem by moving data to an external drive (ideally, use an external SSD). It appears that during the shutdown, the process that should reset the watchdog closes while other background processes actually delay the shutdown long enough to trigger the watchdog errors. Or maybe one of the internal drives fails to shut down properly.
So, free up more space on your Mac by moving files to an external drive. Make sure that you have at least 50GB of free space on your machine.
Boot up your Mac in Recovery Mode and check if the error persists.
If you own an M1 Mac computer, the process is a bit different.
Unplug or disconnect all the devices connected to your MacBook. Then restart your computer and check if the issue persists. If it doesn’t, this indicates one of the devices connected to your Mac may be the culprit.
Many Mac users complained that Photoshop, Adobe Premier, and Lightroom often cause kernel panic errors. Close your Adobe apps or uninstall them completely and check if this action solves the kernel panic problem.
Other users identified AdGuard as the culprit. If this problem occurred shortly after you installed new apps and programs on your Mac, uninstall them, restart your machine and check if the issue persists.
Make sure you’re running the latest macOS version on your machine. Go to System Preferences, select System Update, and check for updates.
Then launch the App Store app and hit the Update button to check if there are any updates available for your apps. Make sure to regularly update macOS and all the other apps installed on your machine.
A number of users confirmed they fixed the kernel panic issue by disabling the FileVault settings. The main role of the FileVault is to prevent unauthorized access to your startup disk. Test this method and check if it works for you as well.
Other users also disabled SIP (System Integrity Protection) and Gatekeeper. Go to Utilities, select Terminal and run the following commands: csrutil disable and sudo spctl –master-disable.
Keep in mind that SIP and Gatekeeper are two important security features that prevent unauthorized access to your Mac. Disable them at your own risk.
Additionally, run the sudo kextcache -i / command to rebuild the kext cache. Restart your computer and check if the kernel panic errors are gone.
To reset your NVRAM, you need to first shut down your MacBook.
To reset the System Management Controller (SMC), turn off your Mac.
Kernel panic errors occur due to unexpected hardware and software problems. Avoid connecting third-party peripherals to your Mac. If possible, use an external SSD to store your multimedia files. If the problem persists, try resetting your NVRAM and SMC.
