Problem with getting into my account
I downloaded a update on my MacBook and it asked me if I wanted it to restart so I answered with yes so I waited for it to restart and it didn’t I restarted it myself and when I turned on and I put my password to get into my account it was loading up but it just filled the loading bar and it stayed like that.
Plz help I need this computer to do my school work thanks for reading
MacBook Air 13", macOS 10.14
