I have reviewed the forum and havent found much to answer my question: I am selling y 2008 IMac8.1 and I want to erase all my personal info. I considered going to disk utility but I want to keep all the software that is installed (Microsoft office and Adobe CS4). If I still had the discs for these programs and the install code I would just do a full erase and reinstall, but I no longer have the discs or the codes are used up. I read that I could create a new user, make it the adminstrator and then delete my other user... however I also read that this doesnt completely delete my personal info and that it is on the Harddrive "hidden." What is my best course of action? Is there something I can personally do or would a certified Mac repair guy be the way to go, even if it costs me a little money upfront?
