Recommended Posts

Hi there,


I have a dell latitude E7280, 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 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.

You're now off-topic but 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:






You need to address that...





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