Mac Account/Login Disappeared...
Hi. After a short break during a days work on my iMac I returned to the usual login screen where my profile name and image appears - however when entering my password it was denied... just repeating the "shake" animation on the password field after each attempt. I restarted the computer and now my user account does not appear at all and instead a blank profile image with the text "Other..." below it is seen, and when clicked, a "Name" field and "Enter Password" field appears. Entering my account name and password here is rejected every time... and I am unable to log in at all. Has anyone experienced this problem before? Any advice on how I can log back in, access my files and return using my iMac normally would be greatly appreciated! Thanks in advance.
iMac, macOS Sierra (10.12.6)
