    I have an iMac with Leopard version 10.5 and am trying to upgrade to Snow Leopard V6.3 but a prompt comes up saying Mac OS X 10.6 cannot be installed on this computer...
    Anyone have a reason why?
    I have enough memory ie. 2 gb and more than enough memory on my hard drive.

    Thanks and regards

    Which iMac?

    Are you trying to use a gray install disc?

    And what exact DVD do you use? Is it a grey Restore DVD, which will only work with the specific model it came with?

    What disc are you using to install Snow Leopard? A retail disc, or a grey install disc from another Mac? The grey install discs that come with Macs are model-specific and will not work on other models. Also, 10.5 is your version of Mac OS X, not the iMac version.

    The message "cannot be installed on this Mac" often means you have a restore disk for a different model. You need the retail disk, as GJ says.

    If memory served 10.6 dropped all PPC support, so if you have a non-Intel iMac that would be why.
