    I have an iMac that I have had for about 2 years. It has alot of stuff on it, and everything that I need I have put on an external hard drive. I was wanted to completely erase everything off of the imac now. I have the install discs it came with. But I never set up my time machine. I have googled to find how to do this and all I see is through time machine but I never set it up. So how do I completely restore it so it is fresh with nothing on it besides the OS?

    Boot from the install disc and open Disk Utility from Utilities on the menu bar. Then select your hard drive and erase it. Simple install OS X after that and you will have a clean install with nothing except the OS X in the drive. Then copy your files back from the ext HD

    I would also upgrade to Snow Leopard
