Fixing Backlight

So what this SSDT does is create a PNLF device for macOS to play with, specifically one with a hardware ID of APP0002. WhateverGreen will handle the rest of the work

No configuration required for most, just drop the prebuilt file into your EFI:

Note: there are some rare cases where the iGPU is called GPU0 or VIDin the DSDT, you can double check by searching for PCI0.GFX0, PCI0.VID and PCI0.GPU0. Whichever shows up is your device

If Windows has been installed on the device, you can also do the following:

Device Manager -> Display Adapters -> Properties -> Details > BIOS device name
  • Note some GPUs may be hiding under "BIOS device name"
