Administrators Bronxteck Posted November 18, 2021 Administrators Share Posted November 18, 2021 try one of the older versions first maybe it is too far of a bios jump to do in one shot. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 18, 2021 Moderators Share Posted November 18, 2021 System is pretty old, not sure it's worth getting it fix. You mentioned system keep getting stuck on Dell Logo, it could be ram or system board issue. If you're stuck on A07 and no other issue, then you could extract the DSDT/SSDT from that and I'll get that patch instead. You can do it from windows using the SSDTTime script from Dortania's site Link to comment Share on other sites More sharing options...
mohammadyolo Posted November 18, 2021 Author Share Posted November 18, 2021 hi Jake yep several days ago it kept on dell logo which i gave it to the repairman to have it fixed. now i wanted to update the bios since the efi you already sent me is needed a bios of a24. if there’s a workround to have catalina installed on it, i would appreciate it FYI, im a newbie on installing mac on laptop, if there’s any link or guidance on how to do DSDT/SSDT extraction, it would be cool then.
