Hello,

I have a stable build with a Gigabyte z370 gaming 7, 9900k and a RX580. I just updated to 10.14.5 to get compatibility with the Radeon VII which is supposed to work flawlessly. But when I put it in, I can't pass the clover bootloader, the screen stays black. I tried to add -v to see the issue but the screen stays black. It's just strange as people seem to have no issue with this card on the forum.

I tried various smbios - iMac 18,1 / iMacPro1,1 - no difference. Should I add something in clover ?

Thanks

Works fine here. Do you have CSM disabled?

Do you have Windows installed? Try downloading and launching GPU-Z (free utility) to check the date of your GPU's firmware. It's possible that your card is running the original launch firmware which didn't have UEFI support.
