Catalina 10.15.7 bluetooth not available Thinkpad T480s

Hi,

I am total beginner with hackintosh, but I couldn`t find the solution anywhere.

My machine is Thinkpad T480S, i7 8550U version.

For my EFI, I am using edited verstion (to make intel wifi work) of this file from GitHub : https://github.com/mohamedspicer/hackintosh-T480s

My EFI: https://drive.google.com/file/d/1wKDT7To7WYcAaTPjQYdKG5bMq_IZumeF/view?usp=sharing

​

I know that it`s a i5 version, but I am honestly glad that it just works.

​

My problem: When I try to launch "bluetooth", I get this message : " You can’t open the “Bluetooth” preferences pane because it is not available to you at this time."

Bluetooth seems to be disabled somewhere in ACPI level, but I dont have enough knowledge to edit them.

I have bluetooth enabled in bios, so the problem is not there.

​

Thank you very much for your responses!
