Hello. I need to disable my cards in Windows 11 and macOS Monterey.

I have two gpus: RX 7900 XTX for Windows and RX 550 for macOS.

I need this scenario. Windows uses RX 7900 and can not see RX 550 and other wise, macOS uses RX 550 and can not see RX 7900.

What i tried to do so far:

- in Windows i disable RX 550 in device manager

- in macOS i tried two methods:

1 I used this code in my config


this method works for now.

2 I tried this method found on Dortania site. This method uses SSDT. But, when I use this SSDT my hack boots a few times normally and at the end I got black screen.




When hack boots I have AMD Radeon Polaris 4Gb. When hack boots using first method I have AMD Radeon RX 550 4 Gb. But when I use device property method I have in graphics two cards: RX 550 and unknown card.

Can any one help me with this?
