This is also posted on the Apple site. I'm getting the "You are unable to log in to the user account xxx" message. I click OK, then the Apple icon appears, and that's as far as I can get. I'm new to the Mac, and have had it running for a month. Set it up initially as "Host Name for local network." Here is where I got into trouble. I changed it now to the 3rd item, "Host name for Internet." I entered a domain name I have, "ve3zt.ca" and I recall at the time that the computer name changed to VE3ZT from local.mini, or something similar. I rebooted and am in this position. Obviously, I made a major boo boo. As I said, I now can't get past the Apple logo. Pressing any keys on the keyboard results in a "beep" from the Mini. That's it! Any help would be appreciated. Thank You. Paul.
