Can I upgrade my iMac version 10.4.11 with 2.16 GHz Intel Core 2 Duo and 1GB 667 MHz DDR2 SDRAM with Macintosh startup disk to Snow Leopard?

It says in the About this Mac that it's a Mac OS X with the above specs, also Model Identifier as iMac5, 1 and SMC Version 1.9f4... if any of that matters?

    Yes you can!

    You can use any retail version of Snow Leopard, but the $29 DVD may require some manual steps. I upgraded direct from OS10,4,11 to Snow Leopard using the $29 DVD on the same iMac as you have (but I also increased my memory to 3GB, but Snow Leopard will work with 1GB). 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.

  • Yes. You can upgrade to Snow Leopard without any problems.

    It will be even better if you give it 2+GB of RAM though.
