Has anyone had any luck with a Radeon VII on Mojave using Clover on an AMD system? I'm at a loss why my poor Radeon VII will not load the driver, even though it's showing up in the system totally normal. I just went back from Catalina to Mojave to see if that would help since other people have issues with Catalina and so far it's behaving identically.

I'm running 10.14.6, Ryzen 3950X, X570 chipset, Radeon VII (works fine in windows) Using the AMD Mac OS Vanilla build, It's spoofing a iMac Pro 1,1 and I'm using the same ol' base kexts. My EFI folder is: https://www.dropbox.com/s/jbb8wf4gm4i2x ... 9.zip?dl=0

I am having the same issue that you are with my Radeon VII and would love a resolution. I have been troubleshooting for ~3 weeks with no luck. I have tried 14.5, 14.6 & 15.1, all with the same issue. I have also tried a handful of SMBIOS configs with no luck, depending on attempted fixes I have researched. Starting to wonder if it is an x570 & RVII issue, I am using the Crosshair VIII.

Hi

I got exactly the same problem as you guys, first tried Mojave 14.6 and last night pumped Catalina 15.2 in but no luck getting hardware acceleration on with Radeon VII.

Okay, solved problem, updated to newest BIOS for motherboard, then there was option to set PCIexpress to GEN 3 mode, this option was not there before, now hardware acceleration works. :)
