Hello Everyone,

 

Most function are working fine with my hacintosh laptop but not bluetooth.

It was worked once but disappeared after rebooting system and never show up again. 

I tried to install brcmBluetoothInjector, brcmPatchRAM3 and brcmFirmwareData with version 2.5.3 in Clover/kext/others and it's not worked.

I also tried to move them on L/E, it's still not worked.

(I've mapped USB by using Hackintool.)

 

This problem keep bothering me for couple weeks. I tried to search resolution by myself but nothing worked. kinda frustrated.

Wish someone can help me solve the problem.

debug doc is attached.

 

Thank you

I guess something wrong on my bcm94352z card.

I tried to used an old Intel combo card. Bluetooth could be detected.(not function tho)

Then, I plugged-in Broadcom card. It worked again and still be functional now.

kinda weird.  Is it possible that only bluetooth part broken but not wifi part in one card? 

Anyway I will keep monitoring.

Thank you Jake!
