pchitech Posted July 2, 2020 Author Share Posted July 2, 2020 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 😉 1 Quote Link to comment Share on other sites More sharing options...

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 😭😭😭😭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. opencore-2020-07-04-182439.7z Quote Link to comment Share on other sites More sharing options...
