Can someone confirm if RX 6700 and 6750 XT are compatible? Thanks in advance.

Thanks, I had seen the list before. But I wanted to confirm if by any chance someone had made it work. I know a person to which, the installation is dropped or cut with 12 minutes remaining.

then you know it is not supported

Even with unsupported GPUs, macOS/OS X can be installed but it will lack acceleration.

Hi, thanks for the clarification.

Legacy Dell 530 booting via OC 0.8.5. This system used to have an Nvidia GT730 and multi boots Snow Leopard, High-Sierra, Catalina, Big Sur and Windows 10.
Wanted to try Monterey but that does not run with GT730 so recently bought a used Sapphire HD7770 GHz Edition GPU (Cape Verde XT chip with DEV ID 683D) very cheap to try out.

The HD7770 works OK with Monterey (no need for OCLP patches), Big Sur, Catalina and Snow Leopard (though not accelerated as SN does not have drivers for HD7770). Windows 10 shows the GPU as R7 250X in Device Manager.

However, with High Sierra (10.13.6), it boots but blank screen on all ports (2x Mini-DP, HDMI & DVI). HDD LED is flashing but Screen Sharing from remote MacBook Pro does not work not does SSH.

During 1st stage loading the Apple log and loading bar is shown, then during 2nd stage, the screen clears and there's a white flash and the bottom third of the screen and no login screen.

boot-args has radpg=15. -radvi does not help (for the DVI ports). agdpmod=piker does not help nor does agdpmod=vit9696.
Tried booting via Clover 5149 but made no difference.

So just reporting here that HD7770 does not work with High Sierra.

Thanks for reporting!

Seems like it requires data injection using SSDT or DeviceProperties.

Is it possible for you to check the status on Mojave? And also check the Device ID support in High Sierra's kext?

I have tried that. I have an SSDT (attached version has most settings commented out) through which I tried different Framebuffers, Connector Patches, connector-priority, etc, etc nothing works.

The issue seems to be initialisation of the GPU.

I even tried changing the SMBIOS from iMac14,2 to MacPro3,1 (which closely matches my Hack 2) but that made no difference.

I do not have Mojave though I could try to install it...just need to get another SSD as I am running out.

It's strange that even Snow Leopard displays correctly even though the GUI is not accelerated.

Can you update the profile correctly? The profile should contain the current hardware specs which you're seeking support for.

Also, for the display, what connection are you using?
