EFI configuration that successfully boots Mojave 10.14.6 on the X220!
If you're interested in this, you may be interested in Catalina on the X220!
After upgrade, it might not boot, this isn't a Clover issue, it's rather a patch issue.
Re-run dosdude1's patches from a 10.14.6 installer.
For my install, I replace the AppleHDA_20672.kext with the two in the zip file.
This doesn't seem to work on the installer, so don't replace it there.
On instructions, replace it in your EFI, replace it somewhere in /System or /Library, I don't remember anymore, and use Kext Utility.
Why would you want to do this? Personally audio levels get buggy for me when switching from headphones to speakers and vice versa, and these ones are more stable.
