How to fix Mac OSX stuck/hanging on progress bar after login
Last night after I rebooted my 2013 Macbook Pro, I was completely unable to login to any user accounts, and even though the passwords were accepted and the login started, it would just sit (hang) at 100% progress, and wouldn’t go any further. After trying a few recovery options, including the feature when you’re “unable to enter password at login screen”, that only resulted in the bootup hanging at the initial Apple logo progress bar at 100%. I ended up spending almost 4 hours trying to figure out the problem, and here’s how I debugged it and was eventually able to resolve the issue.
