If you're setting up a Mac for someone new to OS X and seems to screw up every Windows computer they get their hands on, how would you configure it for them? I'm tired of fixing my brother's Windows problems and thinking about giving him an old Mac Mini I have. His main uses are MS Word, light photo editing, e-mail, and web browsing. My thought was to set him up as a non-admin user so he can't screw around where he shouldn't. Any other things I should consider?
