Administrators Hervé Posted February 25, 2022 Administrators Share Posted February 25, 2022 Your iGPU device id injection is not only unnecessary but incorrect. Intel i7-10750H CPU integrates 10th gen UHD graphics (i.e. UHD 620) with iGPU id 0x9BC4. When you want to fake an iGPU id, you need to inject the id in the correct endianness for macOS, i.e. lowest significant byte 1st. Eg: 0x9BC4 is specified "C49B0000 DATA".

djuby Posted February 25, 2022 Author Share Posted February 25, 2022 Device id 0x9BC4 is nativly supported in macOS as per WEG guide, so there is no need to inject device-id, correct? And for AAPL,ig-platform-id, should I use one for UHD 620 or UHD 630? Current SMBIOS is MacBook Pro 16,4. Should I use a different one? Does it help to know that Windows reports 128MB dedicated video memory for the UHD graphics? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 25, 2022 Administrators Share Posted February 25, 2022 It's indeed natively supported hence why I said it was unnecessary to inject it since it's the iGPU's native id... But I understand that you may nevertheless need to fake id 0x3E9B. Se here. For the rest, I invite you to read this: https://osxlatitude.com/forums/topic/8238-supportedunsupported-gpus-graphics-cards Link to comment Share on other sites More sharing options...
djuby Posted February 25, 2022 Author Share Posted February 25, 2022 Thank you for the referred posts. Really helpful to understand what is supported and what's not. For sure Intel doesn't make it easy. From the second reference looks like this configuration worked on a similar laptop as mine and should work for me as well. Unfortunately I get kernel panic.
