MacBook Pro Won't Boot After Big Sur Update, Any Fix?

My late 2013 Macbook Pro won't boot after downloading the latest Big Sur update 11.6.5. It gets stuck at the Apple logo with a progress bar at about 30 to 40% all the time. I've tried resetting NVRAM and SMC, but no use; running First Aid in Disk Utility in macOS Recovery, no errors; and reinstalling macOS twice, same failure to boot into OS. And I even can't enter Safe Mode. Any tips?

It seems that your Mac has serious software issues as almost all the possible ways to fix a MacBook Pro that won't start after a Big Sur update are useless. Since your Mac can boot into macOS Recovery Mode now, try to rescue files on it ASAP.

To get files off an unbootable Mac, you have no other way but to use a professional data recovery tool. Here, you can use iBoysoft Mac Recovery Mode. This special mode can help you recover data from your unbootable Mac without creating a bootable USB flash drive.

After restoring your data, you can factory reset your Mac. That is erasing your Mac first (This can exclude software errors on your Mac) and then reinstalling macOS in Mac Recovery Mode.
