I must admit I don't use a mac (since I have no money to buy one, and linux works fine for me), but don't bash macs they are very good computers and OSX is a great operating system. What exaclty did you do to mess it up in the first place? sorry I can't seem to help you out more. But if you go to http://www.scopetech.net and post your problem in the Macs forum your sure to get a resoponse and maybe some help.
