[SUCCESS] Ventura on i9-10850K Z490M Gaming X

I really liked your approach to doing the bios mod and injecting the PowerPlay string via opencore, I went down that road. It worked great right up until I needed to reload and patch the bios with the RedBios editor

Just a note here. You don’t actually patch the graphics card BIOS in my guide. Instead all you are doing is getting the correct settings to pass to MacOS to change the behaviour of the card as injected at boot time using the PP_PhmSoftPowerPlayTable string.

Of course you can patch the actual graphics card BIOS, however I would not recommend this approach even if you have a dual BIOS setup on your card.

I am moving to a Sapphire 6900XT and will see if I can update this guide with a PP_PhmSoftPowerPlayTable string that disables ZeroRPM for that card.

DRM
I struggled to get DRM (specifically Apple TV+) working. Executing the following command was the final part of the puzzle.

defaults write com.apple.AppleGVA gvaForceAMDKE -boolean yes

UPDATE:

• For some reason this breaks FaceTime by not allowing remote video to stream and resulting in a "poor connection" message with audio but a grey screen if defaults write com.apple.AppleGVA gvaForceAMDKE -boolean true has been set and shikigva boot arguments are present.
• Executing the following and removing shikigva boot arguments enables FaceTime to work correctly again defaults write com.apple.AppleGVA gvaForceAMDKE -boolean false
• Executing defaults write com.apple.AppleGVA gvaForceAMDKE -boolean yes only seems to be required to start playing a video. After a video is started defaults write com.apple.AppleGVA gvaForceAMDKE -boolean false can be executed if you want use SharePlay in MacOS Monterey 12.1.

Thank you! This fixed DRM for iTunes movies and Apple TV+ for me (although Netflix and Prime still don't work). I don't use FaceTime on my hack, so I don't know if it's broken for me.

Unfortunately the Red BIOS Editor does not support the 6000XT series cards and is limited to the 5000XT and lower series cards only.

For reference, see the following forum post on igorslab.de (makes of the Red BIOS editor) - https://www.igorslab.de/community/t...-overclocking-navi-unlimited.2416/post-162751

I have now posted my full EFI folder in the updated description for MacOS Ventura.

Please note that you must set your own values as per the Dortania guides to use this in the config.plist file and as per the warning in the description.

Guide has been updated for MacOS Ventura.

@mods - would it be possible to move this guide to the MacOS Ventura Desktop Guides section ?
