Hi, I'm upgrading my system and I've found a buyer for my 2003 G3 iBook (14"). Before sending it out to him, I'd like to clean all of my files off the hard drive and generally have it all in good order for him to use. I've tried to delete my files manually but there are just too many. There could also be stuff on there like credit card details that I don't want to give out and don't know how to delete. Can somebody give me a very detailed step by step guide to basically wipe all of my information off so that the buyer has a 'new' machine? Is it possible to return the machine to the point just after I booted the machine up (I remember using 2 CDs) for the first time when I bought it to give the new owner a fresh start? Thanks, Andrew EDIT: I have the last upgrade before Panther.
