My Mid 2014 MBP decided to install 11.2 Big Sur update yesterday evening. After rebooting, it stuck in the boot screen. Left it there overnight but nothing changed.

Then I force-powered off it and booted it in Safe Boot. It completed the update and Software Update shows I have 11.2. However, if I reboot to normal mode, it gets stuck in boot screen again.

Took a look to the logs but didn't see anything definitive.

Any help is appreciated.

Some updates:

  • SMC clearing did not work.
  • PRAM clearing did not work.
  • OS Reinstall did not work.
  • Moving 3rd party extensions out of /Library/Extensions didn't work.
    • Invalidating kext cache didn't work either.
  • There's a /System/Volumes/Update folder with success logs.

I still don't know what the problem is.

Make sure you have at least 35GB of storage free.

  • I have 835GB of free space on the primary drive.

Seems like there's no easy solution to problem other than wiping the whole disk and re-installing.

So, I wiped and reinstalled the system.
