Hi, I have recently updated my MacBook to MacOS Big Sur and have been experiencing random shutdowns. I had similar experience since last 2 MACOS but I was able to fix it by either removing or disabling the below 2 files- AppleThunderboltNHI.kext IOThunderboltFamily.kext I was able to make changes to the OS files on MacOS High Sierra and Catalina but I am not able to make the same changes in the new OS. Where it is mentioned to follow the below steps- Reboot in recovery mode (CMD+R) Utilities -> Terminal csrutil disable csrutil authenticated-root disable mount - uw /Volumes/Macos (Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos) cd /Volumes/Macos (Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos)/System/Library/Extensions rm -rf AppleThunderboltNHI.kext rm -rf /System/Library/Caches/* Kmutil install -u --force --volume-root /Volumes/Macos (Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos)/System/Library/Extensions bless -folder /Volumes/Macos(Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos)/System/Library/CoreServices —bootefi --create-snapshot FORGET THE PROBLEM :-D You’ll need to perform these steps every time you update Big sur with their security updates n all. No need to enable SIP But even after following the above process I still fave the random shutdown. Moreover when I go to the /System/Library/Extensions and look for the the above mentioned 2 files. They are not changed which wasn’t the case into the earlier OS. I am sure I am not the only one facing this issue. Hence requesting to share the solution to this issue so it can help other users too.

Were you able to solve the issue?
