After updating my laptop today, after 20 hours of updating it then took multiple attempts to turn it back on. I walked away in frustration, then came back to it started, so logged in as usual with a set up for the new program. It shut after 5 mins of inactivity, now back to the home screen I’m locked out as it doesn’t recognise my password or any old passwords I have used on this Mac Pro?
Not shure what to do?
MacBook Pro, iOS 11.2.1
