We have a late 2012 imac, which has been running fine since we bought it in Jan 2013.
Last night, my Dad (the admin on the computer) tried to login in, and it kept rejecting his password. Caps lock wasn't on, and he tried several times with no luck. Logs into my Mum's account fine. For info, the dots appear when he types a letter so it's picking up the keystrokes.
After sending him details on how to do the 'resetpassword' via terminal, he restarted it and it accepted his password without the need to do the resetpassword process. Thought it was just a blip.
But...this morning, same thing happened, and he was unable to log in. Repaired disk permissions via Mum's account but still no joy. Left it, went to work, came back and logged in fine. Went for dinner, came back, locked out again.
Does anyone know what would cause this and how to solve it? It's completetely out of the blue and has been running with no issues since Jan 2013!
