chummdoggin Posted August 22, 2022 Share Posted August 22, 2022 (edited) Trying to Boot with 7,1 Does not seem to work. 6,1, at least gets some working DRM. With 7,1 this is what happens. Firmware freeze. Maybe just stick with 6,1 if everything's working? From what I have read, performance is a little better not using IGPU.

Why aren't you using iMac18,1? Do you have a discreet GPU? If you want to use MacPro SMBIOS try this EFI.

I have heard there is kind of better performance not using the IGPU as far as DRM? You have a lot of machines so you probably have an idea!

Slice Posted August 22, 2022 Share Posted August 22, 2022 Clean NVRAM and may be do hardware ClearCMOS. This helps me after using OpenCore. Link to comment Share on other sites More sharing options...
