I use version 0.7.6 of EFI config everything works except Bluetooth. Although in the mentioned whats working section it is listed as working. I installed 12.6.1 macOS. Is there any fix available.

@559911 In the version 0.7.6 EFI config there is already present IntelBluetoothFirmware.kext

Do i need to change it?

Thanks in advance.

if someone still uses bluetooth with Monterey and having that volume hash mismatch issue (which is not a "big" deal, because bluetooth is still working, but unstable from then and need a several restarts, or even full reboot)
seems like https://www.reddit.com/r/hackintosh/comments/tdfgyt/comment/icj9ud1/?utm_source=share&utm_medium=web2x&context=3 - is a some kind of the workaround for this

basically, since I started purging disk cache when noticing my bt mouse starting to stutter - I just opening term and doing

blueutil -p 0
sudo purge
blueutil -p 1

and stable bluetooth lasts for a few hours

@duszmox
idk who is maintaining this rn)

for about hour no issues with bluetooth since reboot with that option enabled
UEFI -> ProtocolOverrides -> HashServices -> true

I found a fix for L460, it has similar specs as T460(s), so maybe it'll help?

I basically set the BT_DEVICE_ADDRESS environment variable to my Bluetooth Controller MAC Address as soon as macOS boot (via /etc/zshenv), and somehow that fix it
