Hello everyone. I just registered on this forum. My problem is this
I have a Dell precision t3610. I was able to make a second hand gpu sapphire nitro rx 580 4GB work by changing from uefi to legacy, but that causes problems because i want to install macosx and one of the premises on the loader i need to use is that i has to have uefi support, so if i change from legacy to uefi again I get no video signal. Computer boots from uefi if i use the Nvidia quadro that came from the system, but that card is useless for what i´m looking for. I need to make this rx 580 work on uefi.

Graphics card works perfect right now but like i said i would like to be able to boot in uefi so i can install macos on another hard drive i have.
I attached the rom i have on my graphics card that i just extracted.

Maybe someone can help me with that.

I would appreciate it greatly

Thanks a lot in advance

U need to check if its a "Miner card..."
Did u check for it UEFI module present in vbios?
Upgrade to the latest UEFI GOP with: AMD and Nvidia GOP update (No requests, DIY)
Make backups and identify correctly ur card/bios...before any flash
