Replace ACPI folder and Config with the attached.

Remove /EFI/Clover/Kexts/Other/IntelBacklight.kext and

Install AppleBacklightInjector.kext to /Library/Extensions

 

Repair permission and rebuild cache

That seems to have broken my wifi, now macos reports no hardware installed for wifi/bluetooth. (using a DW1560 chip)

 

i got the following error message when i did the permission repair and rebuild of the kextcache 

File at path /System/Library/PrelinkedKernels/prelinkedkernel changed, cannot be used.

error 107 rebuillding /System/Library/PrelinkedKernels/prelinkedkernel

 

Then i rebooted the os's and there was no more wifi avalible (no hardware installed) it said.

 

So i restored the ACPI folder with a backup i had from before i alterered it with the new files i got from you.

And wifi now enabled again, but the discrete is not disable still ofc.

Replace FakePCIID_Broadcom_WiFi & FakePCIID in /Library/Extensions

Put the new files back

Run permission fix and rebuild cache again

If you encounter error, run commands again

That worked perfectly. 
Now it only reports the 1 card we want.
thanks a bunch.
