request sapphire rx580 8gb gop uefi need help

Yes, as I mentioned that area of BIOS is usually hidden, due to not being able to detect all card info etc.
I only updated EFI GOP, so what I sent you will only be used if you boot UEFI and disable CSM

Hi guys!

I have a card like this in my Mac Pro and I like to upgrade to latest OS. So I need to prepare the card and update it GOP to be able to see boot screens as I was told. The card is the pc version, but it’s supported in MacOS mojave I use, with no boot screens.

The problem is, I’m totally new to this. Is there somewhere a guide for newbies? Some topics found here are quite advanced and my English are not helping me a lot.

Thanks you for any help in advance.

Im also a Mac pro user… but you need to read a little more on the subject, you can update the GOP driver UEFI PC to the latest version but its not used in macOS boot as it uses a different kind of EFI, so it doesn’t matter.
There is such version but not around as free download, only from 3rd party sellers that do private modifications.

Ah, thank you very much. So, I 'll have to live without boot screens…
