Mac

Hello, my Mac was running Sequoia with OpenCore Legacy Patcher. Recently OpenCore downloaded some updates for firmware/macOS in the background (I didn’t install anything).

I also deleted Windows a few days ago, and the partition went back to the main drive.

After restarting, my Mac gets stuck on the Apple logo. Safe Mode won’t work.

I can boot the Ventura installer, but selecting my main internal volume gives: Com.apple.BuildInfo.preflight.error error 21.

Is there anything I can do without formatting the hard drive?

Any help will be appreciated.
