Is there a guru who can help me? please. I don't know what else to try.

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 ????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

Update ..... I tried to change RAM and use OpenCore 0.6.0, but the result doesn't change.

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 ?

I have tried many combinations of booter quirks but none make me bypass exitbs

Hi @MaLd0n, with the new efi it works all fn keys for brightness and volume, trackpad with multigesture, battery etc. But after a while the system reboots. This is the same thing that happened with my old configuration but I repeat before updating the bios from 9ycn39ww to new 9ycn43wwI had a 100% working system.

My kext folder is the same as the one you sent me with this file https://filebin.net/peckeu6twnk3j089/EFI.zip?t=f436pqbt . If I don't remove it, the file exceeds 3 MB. The only file that I added is datahub in the driver folder, otherwise black screen and does not start, the rest is unchanged.

Send me MacBook-Pro-2 2.zip

No boot, loop on acpi error. image.zip

Hi @MaLd0n, this is the new file. I removed the kext folder otherwise the size exceeds 3mb.
