Hi,

I get a cp error when trying to patch using the micropatcher. Any insights? image

Please check your USB installer and re create it.

As @Ausdauersportler mentioned above, you must create the installation medium (again) if you didn't do so. If you don't have a copy to do so, please use this link, and try this command:

sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/volname

Then try ./micropatcher.sh and ./install-setvars.sh again. Please let me know if it doesn't do so neither.

Thanks a lot @Ausdauersportler and @seyoon20087 . It seems that the MacOS Big Sur Installation kit that I was working with was flawed (downloaded from some torrent). I have re-created the installation medium using another MBP with Big Sur installed (a newer, supported MBP). I patched it using ./micropatcher.sh and ./install-setvars.sh and it worked like a charm. Thanks again!
