    Hi guys i'm new to mac and have purchased an old G5 model Imac to get used to it before i make the leap.
    Only down side the Imac never came with any install discs. I have managed to get hold of a leopard .dmg install file. Is there way i can put this onto a hidden partition so i could later on install it without the need of the cd?

    Hope this all makes sense.

    Some thoughts...

    Burn the Leopard .dmg file to a DVD (using Disk Utility). If done the right way, you end up with a bootable DVD.

    Also, you can just keep the .dmg file around (I created a separate partition to be a catch-all for seldom-used files that I just might need someday).

    The best "protection" against drive/OS failure is to maintain a "bootable clone" of the internal drive on an external volume. CarbonCopyCloner is the app you need for this. You can still download and use version 3.4.7 free of charge from here:

    In order to burn it i shall need a dual layer dvd?? The file is about 7.?? gb

    I mainly wanted to have it on a separate partition on the hard drive so i could just re-install from the hard drive without any messing! This old G5 maybe on its last legs superdrive wise and this one doesn't like to boot from the usb ports :(
