macOS 12.3 Update Causes Problems for 5700/6800/6900 Graphics Cards

[ExpEndUser]

IT WORKED! Same GPU, but different Root:

<key>Add</key>
<dict>
    <key>PciRoot(0x0)/Pci(0x3,0x1)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)</key>
    <dict>
        <key>@0,name</key>
        <string>ATY,Python</string>
        <key>@1,name</key>
        <string>ATY,Python</string>
        <key>@2,name</key>
        <string>ATY,Python</string>
        <key>@3,name</key>
        <string>ATY,Python</string>
        <key>ATY,EFIVersion</key>
        <string>01.01.231</string>
        <key>device_type</key>
        <string>ATY,PythonParent</string>
    </dict>
</dict>

Tested on my second drive. I too confirm that the patch posted above by @zhkong for RX5500XT is working. Thank you guys.

Updated: tested on main system, works fine.

Just to check: You checked, and modified as needed, the ACPI path in the SSDT, didn't you?

Yeah... no. I didn't think about that. And, don't know how to do it. So, I guess I'm stuck until I do more reading.

After use this patch, my PC cannot bootup with 5500xt graphics card

The currect patch is blow, paste from github, link: https://github.com/huijiewei/ASRock-Z390m-ITX-ac-Opencore

Thank you for this! I tried it out on a test drive with 12.3 and did not see any of the issues that I had when I had first tried 12.3 without the changes to my graphics. Upgraded my main Monterey system and it's running fine, too.

Are there any issues with the 6600xt?

@YBuyAMac
As far as I know, it seems to be free of the 12.3 issue.
This already has been told in this thread.

Open Hackintool and look for "display" in the PCIe tab.
If injecting properties through config.plist, copy "Device Path" as shown here:

Asus Z690 ProArt Creator WiFi (Thunderbolt 4) + i7-12700K + AMD RX 6800 XT

@Kalypso478 Known thread, which is already the merger of two previous threads. I've just caught up with the last 7 pages… It's growing fast! That, or someone with a good understanding of GPU properties opens up a new thread so (s)he can own post #1 and edit as required with the latest guide and...

www.tonymacx86.com

If injecting properties with a SSDT, look at "IOReg" and trim it down to the actual ACPI path: Keep only the items with '@' but '@' and anything after). For instance

IOService:/AppleACPIPlatformExpert/PC00@0/AppleACPIPCI/PEG1@1/IOPP/PEGP@0/IOPP/BRG0@0/IOPP/GFX0@0

becomes ACPI path PC00.PEG1.PEGP.BRG0.GFX0, still to be prefixed by the base _SB. Then edit the SSDT in MaciASL:

DefinitionBlock ("", "SSDT", 2, "ETRX", "NAVI21", 0x00006800)
{
    External (_SB_.PC00.PEG1.PEGP.BRG0.GFX0, DeviceObj) // Adapt ACPI path here!

    Scope (_SB.PC00.PEG1.PEGP.BRG0.GFX0) // and here!

Carswell patch confirmed working well with my XFX RX 6900XT MERC319 Gaming Black Limited on MacOS 12.3, happy with the Geekbench score!

Finally it works! in 6900xt
my problem is that I was putting the pciRoot number of the gpu ( ATI ) but we have to put the( VGA controller).

<key>DeviceProperties</key>
<dict>
<key>Add</key>
<dict>
<key>PciRoot(0x2)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)/Pci(0x0,0x0)</key>
<dict>
<key>@0,name</key>
<string>ATY,Carswell</string>
<key>@1,name</key>
<string>ATY,Carswell</string>
<key>@2,name</key>
<string>ATY,Carswell</string>
<key>@3,name</key>
<string>ATY,Carswell</string>
</dict>

Where can I find the property ATY,EFIVersion that I see some of you are including in config.plist? I can't find it neither in macOS nor in Windows. Thanks.
