Unable to reset password in Recovery Mode Unfortunately, I am unable to log in to my Mac Mini OS X (10.8.5). I am trying to recover the password with Recovery Mode by pressing CMD + R. 

I executed the resetpassword command, but the window that appears doesn't list my volume and I can't select my user account.

recovery mode
I called apple support team for further help. They took required information from me and helped to reinstall OS. My data is erased as previously i did not kept any backup and after reinstallation it was like new MAC machine.
