I finally made the time and got it working with your Monterey EFI thread - thank you!

I have been testing on 2 different hard drives. One with Monterey test drive and a working Big Sur.

In the Monterey, my airpods and blue tooth are working but when I'm in Big Sur, bluetooth isn't in the system preferences or menu bar, here is my EFI

Is there something I missed somewhere or is this a known issue with big sur of some kind?

if you're using the same efi for both OS, you will not have bluetooth in 1 OS if you don't switch to Bluetoolfixup or bluetooth injector. one works for BigSur and another works for Monterey
