Reply to Random Shutdown in Big Sur (ThunderboltNHI) driver problem
So these steps used to work until the latest update. (11.6.1 (20G224)) Before this version these steps would stop the Thunderbolt from starting. But with the latest update it not working for me anymore. I am still getting the reboots. Has anyone managed to use the steps listed to work on this version? kextstat | grep NHI Executing: /usr/bin/kmutil showloaded No variant specified, falling back to release    74    0 0xffffff8001a27000 0x30000    0x30000    com.apple.driver.AppleThunderboltNHI (7.2.8) 7032BF7B-7F15-3533-A27B-06F4BBFB99E0 <73 14 13 7 6 5 3 1>
