How do I find out the Disk Space, Video Card and other specs about my Mac?Is there an app for it?

Single click on the blue apple in the upper left-hand corner of your screen. Select "About this MAC" from the dropdown menu. When the box appears in the center of your screen, click on "More Info..." and your MAC will give you all the info you want! Cool, huh?|||There is an app for it. It's called Belarc Advisor and its at either pcworld.com or cnet download.com
