[GUIDE] AMD 6600 on macOS: custom Zero RPM with softPowerPlayTable on SSDT

No notices of a method to inject SoftPowerPlayTable or SSDT into macOS in a real Mac without OpenCore. Sonoma is very high protected to inject modified kexts without OpenCore. Of course, you can try to add OCLP to the EFI and boot from here. I don't think that you'll harm anything but, just in case, you must have a way to reach the EFI and delete OCLP files if it is not working. Best way is to ask this in MacRumors, there are really expert people on real Macs.

Managed to set a curve using the DeviceProperties method in the config.plist. I find that it took way less time than faffing with SSDT's and it worked for me as long as the PCI device path was right.

75C under load now no problem.

Updated this guide to add scripts that make it easier than before. Thanks to Anton Sychev (klich3).
