    I have an iMac Power PC G4 with a 1.25 GHz processor and 256 MB of Memory currently running on OS X 10.2.8 which was pre-installed when I purchased the machine from new in 2003. I have 59 GB remaining of hard drive ( capacity 74 GB ).
    I want to update my operating system - ideally to Leopard 10.5.
    Can this be installed and run on my system as it currently stands ?
    If not what do I need to do to enable it to do so ? http://images.macrumors.com/vb/images/smilies/confused.gif

    You'd need more RAM for Leopard, but Tiger (10.4) should do ok.

    Thanks for this rjs.
    Reading past forum contributions it would appear that to run Leopard I would require a minimum of 1 Gb of RAM. It doesn't look likely that I can achieve this as I don't want to tackle replacing the RAM in the factory slot myself and I live in the sticks - this leaves only the user slot to fill which can only take up to 512 Mb RAM.
    This is the one recommended by Crucial :

    512MB, 200-pin SODIMM, DDR PC2700 memory module
    CT650014
    Module Size: 512MB
    Package: 200-pin SODIMM
    Feature: DDR PC2700
    Specs: DDR PC2700 • CL=2.5 • Unbuffered • NON-ECC • DDR333 • 2.5V •

    My question here ( if the above is all correct ? ) is can I fit and use more RAM in the user slot than is fitted in the factory slot ?
    Assuming that I can this would give me a total of 768 Mb of RAM - what is the most up to date version of OSX ( which would run smoothly ) that I could install ?
