Administrators Hervé Posted July 30, 2022 Administrators Share Posted July 30, 2022 Seeing what you currently inject for iGPU properties, did you try the settings recommended in the Whatevergreen User Manual instead? Probably a good starting point as an alternative to this which clearly is incorrect: And experiment with other framebuffers such as 0x3EA50009 to begin with.

Administrators Hervé Posted July 31, 2022 Administrators Share Posted July 31, 2022 You should also remove these kexts found in the original pack you got from Github: IOGraphicsFamily -> can't imagine what this would do; a patched version used to be required many years ago to fix the garbled Apple logo at boot time but it's long been deprecated CPUFriend + CPUFriendDataProvider -> the data kext would be specific to the OP's i5-8265U and should therefore be re-generated for your own CPU. Then, of course, update all other kexts to latest version. Link to comment Share on other sites More sharing options...
