Previously working configuration: OpenCore 0.7.6, Monterey 12.1, BIOS not sure but applied an update once after buying the Lenovo in late 2019.
The randomly showing "Volume Hash Mismatch" alert was getting annoying, so I thought updating BIOS, OC, Monterey, and everything might fix that.
The BIOS update applied that broke macOS boot was 6SCN54WW, released July 19, 2021.
I'm thinking I can spend a week rebuilding a bootable USB from scratch. I probably need a new EFI, because I don't think the BIOS update made the laptop incompatible with macOS. But has anyone already encountered this issue and fixed it (aside from creating a new EFI from scratch)?
I'm not sure if a BIOS version rollback is possible or if it's what I want to do as a permanent solution.
