Hello there, I just installed my rx6900xt in my MacPro 2019, everything is fine. But does anybody know how I can use them at the same time? Like I use internal radeon pro Vega 2 to render while I'm using 6900xt modeling?Thank you. You can see the rx6900 light is red, I don't know why and how to switch it as the main card.View attachment 525956
Is it a XTXH model? Post a device ID.

Are the 6700 and 6700xt supported?
Maybe but still not likely, the 6600's cards are Navi23 based, the 6800's and 6900's are Navi21. The 6700's are Navi22 so specific Apple drivers would seem to be needed.

The only problem I have is the size of the mouse cursor when using HiDPI modes other than 2:1. It's way too big, but besides that, everything works flawlessly. Also, I just discovered a refreshingly new use case: WoW in 8K. I strongly believe and can not think otherwise, that's what Apple had in mind when they provided the drivers for Big Navi. :lol:
Did you find a fix for this? I got a 6800 XT Red Dragon today and I have the same issue. I also noticed like you that if I use Ctrl to zoom the desktop the pointer goes back to regular size.

You will soon find out :)
Indeed. If Apple supports the 6800 XT and the 6900 XT on the external enclosures I dont see why not?

PS. Just got it, plug and play!

Can you try it on your Z97 build ? I have similar build.

I think 6800 XT should be fine, but for 6900 XT there's a note there says:

7. Only Radeon RX 6900 XT models made or sold by AMD are supported (Device ID 0x73BF).

Not sure if that means only the official edition directly from AMD?

Can confirm, this works like a charm!
No further need for FakePCIID shenanigans.
Do U provide me DeviceProperties fix, SSDT-BRG0 table?
I just begin install BS 11.4 same as Mobo and 6800XT.


thanks,

I have a Sapphire Nitro+ 6900 XT OC and it works out of the box with no spoofing needed. Just an FYI. No SSDT-BRG0 table needed. Only a few of the newer cards need this. Some of the 6900 XT do report the proper Device ID...
