How do I know what version of the System software I have?
Click once on your desktop. Then click in the Apple menu at the top-left corner of your screen. The first item will say About this Mac. Choose that item and release your mouse. In the resulting window will be the version of your System: 9.2 or 10.2.1 or 10.5.6 or something like that. This window also tells you how much memory is installed in your computer.
