Hey!
So I've been using this EFI for a while but I'd soon need to update to get support for my HDR monitor & the new Final Cut Pro, so I'd need to install Big Sur, is there a way for you to update this EFI you had provided me? (What I'm replying to) Or just explain to me what it is you did, I've been trying to do it myself with the latest EFIs (even tried the OpenCore one, but shouldn't have because I did a reset nvram and then lost my UEFI boot menu, p.s. was able to get it back).
I'll explain once again my setup / what I'm doing. I have 2 graphics card, one is an RTX 2070 for Windows only, one is an RX580 for macOS. When I startup my computer for Mac, I use the integrated graphics to boot, then, once I'm in macOS, plug the HDMI in the RX580 instead of the motherboard, and it uses those graphics instead. It's been pretty great as of now, everything works, but I'm starting to have the need to update. I'd be willing to try OpenCore too, if ever that's easier.
Thanks again for your amazing support.
