I have the exact same specs as
@BayCityRoller and he successfully used this guide to install Big Sur using Robbish's EFI folder including Robbish's USB mapping and even Robbish's SSDT-PM (see
this thread). It's possible he altered the config.plist slightly but no way to know which is why I am hoping he will see this and share his final working EFI folder with me. We have the same MB, CPU, and GPU and we have both set our BIOS settings exactly as this guide says to. I've never seen anywhere in any Hackintosh install ever (been making hackintosh's since Snow Leopard) where the hard drive brand matters.
