I need to bring my TiBook to the apple store to have them look at an issue with the display. If I need to leave it with them or they need to send it out, I am a little concerned about personal info on the machine. This is mostly email accounts, contacts, ical info and the like (no work or banking info) and I have backed up all of my files, but has anyone had a problem or suggestion how to best prep a system before turning over to Apple for repair? If I enable to login screen at start up, this could help prevent access to info in my user account? Maybe at the end of the day they could have total control over the system if they wanted, and I don't really have anything of importance to anyone else (they can copy my itunes library), but this just got me thinking about how much is on it and what I would do if I used if for banking or a business.
