Hi Razor7, did u manage to get your rig running? In case you did, could you pls share your EFI?

Im running crazy.. I’ve managed to get to the BIg Sur installation process but I get each time "An error occurred loading the update" with 12 minutes remaining. I have followed Dortania’s opencore guide and have revisited it a thousand times trying to identify the error in my config.plist file but everything seems to be OK. Have as well remade the bootable USB several times with different original copies of Big Sur and opencore, downloaded the latest kext/driver versions and even compiled my own ACPI files (usd dortani’as as well) but I keep getting the same error.
