Alright, so I experienced with Visage Login (bad idea). Visage login is a program that lets you customize Leopard's login screen. It noted, however, that it would always save the defaults. When I tried to restore it to its defaults, it didn't work. So, I lost my original Applelogo.tif. If someone could upload their original Applelogo.tif, that would be great. You can get to this file by opening finder, pressing command+shift+G, and copying this: "/System/Library/CoreServices/SecurityAgent.app/Contents/Resources/" exactly into it (without the quotes of course). thank you so much in advance. i really would appreciate this.
