Hi izuchukwu225,
Thanks for coming to Apple Support Communities for help today with your MacBook Pro update. It sounds like it's stuck on a progress bar.
It may be resolved at this point, but if not try restarting in safe mode: How to use safe mode on your Mac.
If the Mac starts up all the way, check for third-party start up items that may be interfering.
Let us know how it goes.
Have a fantastic day!
