Everything About Your Mac
If you need to find something out about your Mac, you may be wondering where to go. You’ve probably heard of System Profiler, About this Mac, or a number of other tools. Here are the two that we recommend to find out everything you need to know about your Mac.
System Profiler

System Profiler can report your Mac’s current profile including installed RAM, drives, power information, expansion cards, video memory, and more. You can launch System Profiler from your Utilities folder or by choosing “About this Mac” from the Apple Menu and clicking the “More Info…” button.
While System Profiler can tell you about how your Mac is currently configured, there are some important things it can’t tell you.
MacTracker

Mactracker is a freeware program that keeps a database of every piece of Apple hardware ever released. Where System Profiler can tell you about your specific Mac by looking at the hardware, Mactracker can tell you about your model. Download Mactracker and launch it. You’ll see “This Mac” item in the left side of the Mactracker window.
Open the listing for your Mac that comes up in the right side of the window and click the “Memory/Graphics” tab. You’ll see the second item on the tab labelled “Maximum RAM.” Compare this to your current Memory in System Profiler to see if you can upgrade your RAM to be more productive. Explore the other tabs to discover the other useful information packed into Mactracker.
MacTracker is updated several times a year with new model information and has not yet been updated with the glut of new models Apple has already announced in 2009. Check out the other cool features like the Time Line that displays all the models released in a given year, and support Mactracker by donating on their website if you find it useful.
