It seems to be a fairly common problem on some Lenovo notebooks from the comet lake series. In particular it seems that nobody who has a lenovo from the thinkpad X1 or X2 series with the comet lake processor has managed to overcome this Exitbs, maybe my thinkbook 13s-IML is part of the same family boh?

 

Anyway I don't give up, but a hand is always welcome ūüėČ

Obviously I tried but I don't know which combination to try anymore.

I came to a bitter conclusion no one was able to install catalina on a lenovo x1 carbon with comet lake the 20r1 series. My thinkbook derives from this notebook the project is identified as 20rr and we all have the same problem ūüė≠ūüė≠ūüė≠ūüė≠EB # LOG: Exitbs: Start https://github.com/bomdurup/x1c7_2020_hacintosh

The bios, however, is locked for writing, therefore the various methods of modifying the cfg lock do not work.

At this point I believe that only opencore developers can do something.

Attached you will find the log of opencore if someone wants to help me thank you in advance.
