MacPro build - i9 11900K Z590 Asus Maximus Hero XIII RX6900XT (XFX) build - Installing MacOS Ventura (13.2.1) on backup drive

[CJWKOREA]

I just did a successful install of MacOS Ventura 13.2.1  onto an external SSD and noticed several things - While I can load the OS, the setup quits parts way due to a lack of network options and goes back to the Opencore boot menu.  Is there a way of using the previous configuration from Monterey on Ventura? There seems to be no graphics acceleration now either...  I hear conflicting reports that the RX6900 are supported due to the 2019 Mac pro. 

  

I do believe my files are still on the website for  Maximus Hero XIII with RX6900XT.  

 

Anyone?

Got graphics somewhat working, but I cannot get past the setup as networking causes it KP and restart. 

Again, I can access MacOS Ventura, but the setup process KPs upon network settings and setup. I chose no network and the same thing occurs.

Start with this efi folder and save one ioreg with ioreg explorer

EFI.zip

-Delete old EFI folder and paste new. Don't use merge files
-Don't use Drag and Drop into EFI partition. Use Copy/Paste instead
-Reset NVRAM one time - with OpenCore use entry "Reset Nvram" / with Clover use F11 key on boot screen

Ok, so now I have gotten everything except WIFI and BT to function,  Graphics card is now NAVI21  I do have full Metal acceleration.  Seems like Intel WIFI/BT plugin not working.

This gpu need fake device id to work with full acceleration.

[CJWKOREA]

It is currently working with full acceleration. I can compress videos, and get full metal acceleration. It is the same card as on the MacPro 2019. It just recognizes as a Navi21, not as a GT6900XFX

Biggest issue is BT and WIFI.

is just cosmetic, but u can change it with simple patch if u like

[CJWKOREA]

Ok, which patch are you referring to?. I am wondering about the old profile from MacOS 12
