Cannot log-in to 2017 macbook
I have updated Catalina and migrated data from my 2013 macbook air to a secondhand 2017 12 inch macbook this afternoon. There were a few issues with my apple ID needing to be re-entered several times, but I am now looking at the log-in screen and it won't accept the Name or Password. When I look on the MB Air, I can see that this computer is logged into apple ID, but cannot access anything. Any suggestions ? Do I need to reboot the whole disk ? Help please.
MacBook, macOS 10.15
