I rely on a PowerColor Red Dragon RX 580 8GB as my preferred GPU for my Mac Pro, yet I’m unable to access the boot picker even after installing OpenCore and removing my GT 120, which used to display it. My main guess is that because this GPU is a dual BIOS unit, I’ve placed it in the second slot while the first one runs the mining BIOS (which is why I can’t see the boot picker). Should I instead install a Reggio BIOS on the first slot to enable access, or is my assumption incorrect? Any guidance would be greatly appreciated.
