Thanks but I cannot boot into Recovery Mode with this restore method (It appears the black screen and returns the Opencore bootloader screen. I have no idea why. I can boot into macOS easily.

Quick question: Could you help me to make "mount disk" work. I just got this:

I have one more issue that when I shutdown my laptop, the screen is off but fans still spin, usb ports are still powered. I’ve tried using FixShutdown-USB-SSDT method but nothing’s changed. Please take a look at the previous attachment. FIXED!

Btw, thank you for your help

Many thanks. I’ve put them into EFI but Wifi still remains unchanged. If you have time, please let me know if I could send you some files to fix that.

Here you go. Thanks https://drive.google.com/file/d/1v6boxC_m6OlGoV0flpNIuUG5gIkRnVRG/view?usp=sharing

I’m a novice. I’m sorry to bother you but could you instruct me to inject this. I’m still skeptical of it.

Could you tell me how to manage to make Wifi work? Or I’d better wait for an update of AirportBrcmFixup.kext Wifi card is bcm94352z. (Bluetooth works well)
