I have a Macbook Pro running Mavericks. I was using it just fine, stepped away and it had gone into powersave mode. Upon my return I turned it back on, no response, so I held the power down for a short while and then rebooted. Now my user account is missing. I can see Administrator or Guest.
This is a company supplied Macbook so I don't have the administrator password.
Any ideas as to what has happened? I can see my user folder is still there is I login as Guest.
