    As you can see this is my 1st post with the forum, the 1st of many I hope.

    Now for the question:

    I have one of the new Imac's that came with Tiger and then I put Leopard on it when Leopard was launched.
    I am now selling the 20" imac so I can get a 24" imac.

    How Can I put the imac back to new so the new owner cant see what i did with the imac. ( does that make sense, hehe )

    Do I just reload Leopard???
    Or do I have to do something else to erase all information!

    Like i said guys i am a newbie, so if this is stupidly simple, forgive me!!

    Put either the Tiger or Leopard install disk in and in Options, choose Erase & Install :)

    It will have none of your data and the operating system you put in...

    In R4, more or less
    I would recommend doing the following:

    1) back up everything you need off the old machine.
    2) boot your old machine from the system restore disc
    3) go to one of the menus that will have a disk utility program in it
    4) format the hard drive using the security option for zero-out (7 pass probably not necessary, unless you happen to have my SSN on it)
    5) and reinstall the original OS that shipped with the machine. Unless you want to buy the new owner a Leopard license.
