    Here's a screenshoot of VideoProc on my system. It shows support for both HEVC and H.264. I am not using WhatEverGreen and don't have the iGPU enabled.

    First issue will definitely get fixed. For the second issue, do you get any error messages? If you go with the iMacPro1,1 route, WhatEverGreen is not needed and also shikigva=1 flag. You can just back up your current CLOVER folder and try the new SMBIOS. If anything stops working, you cna...

    Any idea why this command is no longer working in 10.14.5: com.apple.driver.AppleGraphicsDevicePolicy Find: BA050000 00 Replace: BA000000 00 I have to use WhateverGreen to get past the black screen at Desktop on boot.

    I am using iMacPro1,1. Unfortunately I have not had any success with other SMBIOS profiles.

    Since updating to the latest beta, my system has experienced random lag/freeze twice now while Safari is open. Never had this issue with beta 3 and below.

    Yes PM is working as far as I can tell. Looking at the Intel Power Gadget, I see the CPU hovering around 0.8 MHZ on idle.

    What’s the new values for graphics device policy? I have upgraded to b2 and my system is booting to black screen.
