Big Sur and AppleThunderboltNHI.kext

[admiralali]

Installed the latest Big Sur update 11.7.3 on my MacBook Pro (2014 model) a few minutes just before posting this, and still worked for me. sorry for my typo in my previous post. My OS volume is "MACOS" so make sure you change that in the steps below:

Reboot in rescue mode (CMD + R)

Open TERMINAL app, and type the following (in exact order):

-----------------------------------------------------------------------------------------------------------
$ csrutil disable

$ csrutil authenticated-root disable

$ mount -uw /Volumes/MACOS

$ cd /Volumes/MACOS//System/Library/Extensions

$ rm -rf AppleThunderboltNHI.kext

$ rm -rf /System/Library/Caches/*

$ cd /Volumes/MACOS/System/Library/Extensions

$ kmutil install -u --force --volume-root /Volumes/MACOS

$ kmutil clear-staging

$ kextcache -i /

$ bless --folder /Volumes/MACOS/System/Library/CoreServices --bootefi --create-snapshot
-----------------------------------------------------------------------------------------------------------

Then just restart the device and you're good to go.

Thank you, man! This worked perfectly for the latest Big Sur 11.7.9. And no need to remove IOThunderboltFamily, btw.
