Cannot login to my user profile on Macbook Pro after laptop froze
Does anyone know how to solve this problem - I went away from my desktop for about ten minutes and when I came back the screen had completely frozen. I turned the laptop off and restarted but now it only comes up with an old - no longer in use - admin profile or guest, not the admin profile I have been using for the past four years or so. Previously when this has happened on occasion I am able to log in to the guest, then log out and my profile shows up. But not this time. No matter what I have tried I cannot get into the laptop on my current profile.
I then tried going to disk utility and first aid, but this message comes up:
First Aid could not unmount the volume for repair
I am at a total loss.
MacBook Pro 13″, macOS 10.13
