How to use it ?

⚠️ Dont forget to recreate the plateforminfo section and change SMBIOS data (using GenSMBIOS or any other tool) ⚠️

Open /EFI/OC/ACPI/SSDT-GPU-SPOOF.aml with MaciASL.

Edit :

External (_SB_.PCI0, DeviceObj) & External (_SB_.PCI0.PEG0.PEGP, DeviceObj)

For example :

ACPI(_SB_)#ACPI(PC02)#ACPI(BR2A)#ACPI(PEGP)#PCI(0000)#PCI(0000)

Now converting this to an ACPI path is quite simple, remove the #ACPI and #PCI(0000):

\_SB_.PC02.BR2A.PEGP

Dont forget to compile it back.
