    The only thing to do is upgrade your operating system version to 10.5 or higher, as your computer permits.


    Start with getting more information about your computer. Go to the Apple in the upper left corner of any window, then "About This Mac", then "More Info..."  Copy and paste the information here, but omit the serial number and Hardware UUID (if present).  Compare it to the requirements for each system version below, and we can also provide guidance once we know what computer you have.

    I have exactly the same problem.


    My computer seems to match the Leopard 10.5 system requirements as follows:


    Hardware Overview:

      Machine Model:        PowerMac8,2

      CPU Type:                  PowerPC G5  (3.0)
