    If you are using a PowerMac as indicated in your signature, that is correct.

    If you are indeed using a old PowerMac, then you can't upgrade to any newer, modern OS X version as these need newer, Intel CPUs.

    PowerMacs use older technology IBM PowerPC CPUs and are incompatible with new OS X systems.

    You need to give us more info to make sure, you, in fact, have an old (pre-2006 ) PowerMac or newer (post 2006) Mac with an Intel CPU.

    The maximum OS X version for a PowerMac is OS X 10.5.8 Leopard and that is it!

     

    To find out info about your system,

    Click on the Apple symbol in the upper left of the OS X main menu bar. A drop down menu appears.

    Click About this Mac. A smaller popup window appears. This gives you basic info like what version of OS X your iMac is running, the speed of your iMac's CPU and how much RAM is installed.

    Click on the button that says More Info. A larger window appears giving you a complete overview of your iMac's hardware specs.

    Highlight all of this info and copy/paste all of this into another reply to this post, editing out your iMac's serial number before actually posting the reply.

    This will tell us everything about your iMac so we may begin to help with your iMac issues.

     

    If you have a Mac with an Intel CPU, then your Mac must meet ALL of these requirements to install OS X 10.9 Mavericks.

     

    To install Mavericks, you need one of these Macs:

    • iMac (Mid-2007 or later)
    • MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
    • MacBook Pro (13-inch, Mid-2009 or later),
    • MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
    • MacBook Air (Late 2008 or later)
    • Mac mini (Early 2009 or later)
    • Mac Pro (Early 2008 or later)
    • Xserve (Early 2009)

    Your Mac also needs:

    • OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
    • 2 GB or more of memory ( strongly advise, at least 4 GBs of RAM or more)
    • 8 GB or more of available space
