    OS 10.5 will be very difficult to find for purchase and will cost at least $130.
    Your Mac will run OS 10.6 (Snow Leopard). And Snow Leopard currently costs $20. Make sure your Mac has at least 1GB of memory.

    To upgrade, as I do with any major system upgrade, I would recommend installing Snow Leopard on a fresh partition. You can create a partition using Disk Utility that is on the Snow Leopard DVD. Create the partition on your internal drive (if you have room), or on an external drive. During the installation, the installer will search your mac for other partitions and ask if you want to import OS settings, apps and files from the "old" partition. If you import, you will end up with a Mac that will boot with either OS (hold down the Option button during start up). The partition with Snow Leopard will have a copy of all your apps and files ready to use. Printer and scanner drivers may need to be updated manually though.

    I upgraded directly from OS 10.4.11 to Snow Leopard using the above method.

    More info about installing Snow Leopard can be found by doing internet search for "How to Perform a Clean Install of Snow Leopard OS X 10.6 by Tom Nelson".

  • You should be able to run Leopard 10.5.8 on your 2006 iMac. The tricky part will be finding a copy to purchase.
