How to Fix Mac Kernel Panic and Recover Lost Data?

The Kernel Panic error can get in the way of you seamlessly booting and using your Mac. It occurs when macOS encounters an unrecoverable system-level error, and cannot continue running, forcing the Mac to stop and restart.

A hardware issue, a failing storage drive, a troublesome logic board, and application errors or, incompatible peripherals, can cause a Kernel Panic. Luckily, there are ways to fix the Kernel Panic error. Read on to know more about this error.

What’s causing Kernel Panic on Mac?

Kernel panics are sometimes confused with application crashes or startup problems. But they are very different; with a kernel panic, your Mac will display the kernel panic message and restart automatically. Whereas an application crash affects that one app and leaves everything else running normally.

User reports that kernel panics occur for a myriad of reasons. Here are some of the frequent causes of Kernel Panic error on Mac:

• Damaged or incompatible hardware, including external devices attached to your Mac

• Faulty software

• Not enough RAM 

• Recently installed applications or system updates

• If Kernel extensions crash or have bugs, it causes a kernel panic

• Corrupted or conflicting system extensions

• Third-party security software

• A buggy or incompatible VPN driver 

• Antivirus software

Remember to back up the necessary files of your Mac before applying the below fixes.

How to fix Kernel Panic [Software Solutions]

1. Check Crash Reports

Once your system reboots after the kernel panic error, a crash report pops-up stating that the system restarted because of a problem. Click Show Details to know what triggered the panic. 

If you already dismissed the dialog box, check the crash reports from the Console app.

• From the Finder, open Console, go to Reports.

• Look under System Reports for the files starting with “Kernel.”

• You even manually check the crash report:/Library/Logs/DiagnosticReports/

• Kernel panic logs are named: Kernel_YYYY-MM-DD.

2. Update all your Mac software

Start by checking if your Mac is using the latest available macOS version. If not, update it now: 

• Apple menu > System Settings > General > Software Update.

• If new software is available, click Update Now to update the macOS as well as Apple’s built-in applications.

• Also, go to App Store > Updates to see if the latest updates are available for the third-party apps of your Mac.  If available, tap Update.

3. Boot in Safe Mode

Boot your Mac in safe mode to check which startup apps or corrupted applications is culprit behind the Kernal Panic. Safe Mode loads the essential components of macOS while disabling third-party extensions

Boot Mac with Apple Silicon in safe mode

• Press and hold the power button until “Loading startup options” appears.

• Select a hard drive, hold the Shift key, and click Continue in Safe Mode.

• The computer restarts automatically. When the login window appears, you can see “Safe Boot” in the menu bar.

Boot an Intel-based Mac in safe mode

• Restart your Mac, hold the Shift key until you see the login window.

• On the first or second login window, you should see “Safe Boot” in the menu bar.

Once in Safe Mode, remove corrupted applications you installed recently and disable third-party apps that launch on startup. 

To disable startup apps in Safe Mode in Mac:

• Click Apple menu > System Settings > General > Login items

• Choose an unwanted startup program to remove and click the minus button to clear it from the list.

Go ahead and restart normally. If no kernel panic occurs, add one of the startup items back, then restart. Repeat and test each startup item until you’ve found the culprit.

4. Check third-party extensions

Often, at times, some apps install kernel extensions for deeper interaction with the Mac. However, an outdated extension could cause instability and may trigger a kernel panic error. Disabling third-party extensions can help:

• Open System Settings > Privacy & Security > Extensions to see loaded system extensions.

• Or use Terminal: systemextensionsctl list to list active System Extensions.

• To remove a problematic extension, uninstall the app with which it is connected or go to System Settings > Privacy & Security > Extensions, locate the extension, and disable or remove it.

• You can even remove suspicious system extensions or trash related apps properly: Check System Settings > Privacy & Security > Extensions.

• After that, restart your Mac to see if kernel panic stops.

5. Turn off peripheral devices

Plug off the printer, the network adapter, USB hubs, external SSDs, Thunderbolt docks and other external hard devices connected to your Mac, restart the system, and connect one device at a time to identify which external device is causing kernel panic. 

6. Run Apple Diagnostics

Use Apple Diagnostics to verify if hardware issues are causing kernel panic. 

For Intel-based Macs:

• Choose Apple menu > Restart, press and hold the D key until Mac restarts.

For Macs with Apple Silicon: 

• Restart your Mac, hold the power button until the startup options appears.

• Choose Options

• Press Command + D on the keyboard.

Run Apple Diagnostics Test and View Its Result

• Apple Diagnostics would launch automatically and test your hardware for issues. 

• See the Apple Diagnostics reference codes to interpret the diagnostic results, and if any problem is detected, visit an authorized Apple Genius Bar and have your Mac repaired.

7. Reset SMC and PRAM/NVRAM

NVRAM/PRAM (Non-Volatile Random Access Memory/Parameter RAM) is responsible for speaker volume, screen resolution, startup disk selection, and time zone information. SMC (System Management Controller) controls power-related settings of the Mac. Kernel panic often arises from conflicts in these areas, so try resetting them to resolve Kernel Panic error.

Intel Mac:

Reset NVRAM/PRAM:

• Shut down your Mac, turn it on, and press and hold Command + Option + P + R keys for 20 seconds.  

• Release the keys and allow your Mac to boot.

Reset SMC:

• Shut down your Mac.

• Press the power button while holding the Shift + Control + Option keys for 10 seconds, release them, and then turn on your Mac.

For Apple silicon Macs (M1/M2/M3/M4):

• SMC no longer exists. NVRAM resets automatically. Simply shut down the Mac for 30 seconds and restart. Boot the Mac again to see if kernel panic is there or not.

8. Run First Aid in Disk Utility

Run First Aid in Disk Utility to detect and solve any disk error on the Mac that can be causing Kernel Panic.

• Open Finder > Applications > Utilities> Disk Utility , choose the disk to repair, and click First Aid.

• Click Run when a prompt appears asking if you want to run First Aid on your disk. 

9. Reinstall macOS

If all the approaches fail, reinstall macOS using a macOS feature called Reinstall macOS. This will install a fresh copy of macOS. Reinstalling macOS is the most decisive answer to all your OS problems.

Practical habits that can prevent future Kernel Panics

• Prevent minor bugs and connectivity glitches by regularly updating macOS.

• Avoid installing software from untrusted sources and keep all software updated.

• Monitor your system performance regularly using Disk Utility. 

• Declutter and optimize your storage regularly.

• Use genuine peripheral products to avoid compatibility issues.
