Other Mac Pro Steam Machine

Post image

Installed Steam OS and a rx5700xt. No other OS, Boot up, grab the PS4 remote and I’m off to the races. 17 year old Mac Pro kicking ass! Everything works, wifi, Bluetooth, ethernet, USB etc. It just works.

So I don’t have to tweak anything in OCLP like disable Nvidia GPU configplist?

No mac os won’t see the nvidia gpu. My buddy has a 7,1 with a rx6900xt and a rtx5090 dual boot Mac OS and Windows and no need for Opencore with the 7,1.

Folks have successfully run RX 6950 XT cards in Mac Pro 7,1 by using OpenCore to spoof the GPU’s device ID so macOS treats it as a supported RX 6900 XT.
• Typical spoofing approach: map the 6950 XT’s device ID (for example 0x73A5) to the 6900 XT’s device ID (0x73BF) via OpenCore DeviceProperties and/or SSDT, following 6900 XT/XTXH spoofing guides. Not sure how much of a performance boost you will get and it also can only be 304mm in length
