Hi there,

 

I have a dell latitude E7280 7280, i got to install Monterey 12.3 but Bluetooth and

 Airdrop are not working.

Specs: Core i5 7300U, Intel 620 graphics.

 

Any help please? here is my EFI.

 

Also i`ve noticed that the CPU is running pretty hot, and system preferences is laggy.

 

thanks!

What's the model of your Wifi / BT combo?

You have both Intel and Broadcom kexts for Wifi, but only Broadcom BT kexts.

If you have Intel combo, then remove all the Broadcom kexts and add the Intel BT kext: IntelBluetoothFirmware.kext

Post IOReg file

Thanks for replying,

 

I have intel wifi/BT combo, I erased Broadcom kexts from OC/Kexts and config.plist and added IntelBluetoothFirmware.kext and bluetoolfixup.kext, now Bluetooth is working, but I can't get Airdrop to work.

Do try and disable that SSDT-ALC256 patched tab of yours. I don't think you need it, especially given that you do not appear to use CodecCommander kext.

 

Then, there appears to be a discrepancy between your OC config and the info shown in IOReg:

ALC_layout_in_IOReg.jpg

 

You need to address that...

'pretty sure ALC256 layout id 11 (0x0B) should work perfectly.
