The Dock is one of the most used tools on your Macintosh. It holds all of your most used programs. By default this is on the bottom of your desktop. But did you know that you can move the Dock to the left hand and right hand side of the display. Many people prefer this to the default position. Try moving your Dock and see where you like to position it.
