CANNOT UPGRADE TO MONTEREY

[Edwin]

Hi guys, somehow I cannot upgrade to Monterey. When I do this, the system freezes. Who can help me out?
Thanks in advance!

Try using this OC 0.8.0 EFI, which is set for a 6-Core AMD system.

I have reused the PlatformInfo data from your EFI.
I have cleaned up the OC sub-folders, removing unnecessary/duplicate SSDT's and kexts etc.

See if this allows you to boot Monterey on your system.
