UPDATE
I did it.
I had to change HideAuxiliary to NO in the config file and then add the NVMeFix kext to make it detect the two NVMe SSDs.
The only thing in MacOS startup (login screen) the resolution seems to be minimized, everything is very clear and bright. Once logged in, the resolution changes automatically, even passing to 240hz.
But I think it depends on a setting of MacOS and not of the config file.
For the rest, everything would seem to really work.
Great job scope666. Thanks again.
Can you attach a screenshot of where the boot process fails?
Have you already tried resetting nvram?
He’s right, that’s usually needed between updates.No, didn't try that, I hosed Big Sur once with that so I try to avoid using it.
