Hi, i just installed bigsur at my laptop recently. but i got several problems, which are :
- Wifi not working
I was following the instruction to add some kext files to EFI folders and change the config. However, it doesnt work until now. I tried to reset nVRAM but still doesnt work.
- Speaker and Touchpad not working
I still doesnt have any idea how to solve this problem.
Could you help me please?
