Is there a way to upgrade from OS X 10.4.11 to OS X 10.6 using the upgrade package?

    You can use any retail disk of Snow Leopard to upgrade from OS 10.4.11 to Snow Leopard. Provided of course you have an Intel-based Mac.

    I upgraded using the $29 Snow Leopard disk. Here are the steps I used:

    1) First, keep (or clone to an external bootable drive) your old bootable partition with the old OS on it. This allows you to have a backup and still be able to start up with OS 10.4.11, if you wish to, after Snow Leopard is installed.

    2) Start doing a clean install of Snow Leopard to a fresh partition. In order to do a clean install with the $29 DVD, you will have two options when you start up from the DVD... "Utilities" or "Continue". Select "Utilities" and when the Mac restarts, select "Disk Utilities" from the "Utilities" menu. Do a format of your "fresh" partition and then QUIT "Disk Utilities".

    3) Now Snow Leopard will begin installing. During the install, it will search your Mac for all other partitions with an older OS and then ask you if you want to import your OS Settings, Applications and Files from one of those other partitions. Do this for a very smooth upgrade transition to the new OS. (If you decide to not import, then you will end up with a clean install of Snow Leopard instead.)

    4) After restarting with the newly installed Snow Leopard, go to the Apple Menu and do Software Updates to bring your system up to OS 10.6.8.

    5) All my Apps from OS 10.4.11 continue to work in Snow Leopard, but some of my printer drivers and scanner utility did not. Until I found those upgrades, I was still able to start up from the OS 10.4.11 partition to use my printers and scanner. To change the Start Up partition, either use the Start Up Disk in System Preferences... or press and hold "option" while your Mac starts up.

  • You will likely need the Mac Box set and also be running on an Intel Based Mac to upgrade to 10.6

  • No. Not if your Mac has a PPC processor. You need to have a Mac with an Intel Processor.
