Searching for system information on a Mac running Mac OS X 10.6 Snow Leopard can be confusing to the uninitiated. For example, if you're trying to figure out what RAM chips are installed in what slot on your device, you need to pop open About This Mac, click the More Info button, and then scroll down through the list of hardware, network and software items until you find the proper info. Even then, if you're looking for details on how to upgrade your system RAM, you'll need to do a web search for instructions.
Mac OS X 10.7 Lion will have a new features that should make it easier for everyone to quickly find the system data they need. A new app, System Information (see above), is available from About This Mac, but provides Mac owners with information displayed in a much more graphical and understandable way.
When launched, System Information initially shows two overview panes, one with data about the operating system and available software updates, and another displaying high-level info about the computer hardware. From the software pane, users can launch Software Update, while the old System Profiler can be launched by clicking the System Report button on the hardware pane.
