I might be doing this wrong, but I first copy/paste the new EFI folder to currently installed MacOS Monterey. After I did the NVRAM reset it now says this on boot up and stays there: Unsupported PCH
I'm now trying to run the whole installation process with your new EFI, but now it says:
"KextLog: Loading FileSetKC(s)
KextLog: Laoding Pageable KC from file /System/Library/KernelCollections/BaseSystemKernelExtensions.kc
KextLog: Collection UUID matches with loaded KCs.
deferred rematching count 1
IOG flags 0x3 (0x51)"
It doesn't want to continue after that.
