    Hi, thanks for posting this — I have got as far as step 3 fine — the EFI is working, I get the boot screen. Going to System Preferences/Software Update I only get the option to upgrade to Monterey. What is the procedure to upgrade to Catalina form this point? I have tried downloading the full installer and that doesn’t work (I get the message “This version of macOS 10.15 cannot be installed on this computer”.

    Thanks for your help, Chris

    Hi Chris,

    Can you try with Big Sur just to check? The message that you receive points to compatibility with the machine which would indicate Open Core not working.
