Hi , Is the Mac set to auto login ?
Is there more than one user on the Mac?
Can you login to any account ?
Hello I have two users on this computer Myself as the root and my wife as guest. When I started my computer I don't get the normal login page. It looks different. It doesn't have our accounts listed. Just a grey box that says Name and password
Are you there
A safe boot can also help ,Turn off the Mac .Power on the Mac .Hold shift on the keyboard using a USB keyboard , while powering on the Mac and booting , boot to safe mode.Once booted to safe mode , restart and boot as normal .Full details here :-http://support.apple.com/kb/ht1455
