OK so firstly to take screenshots on a mac, hold command, shift, then 3. A screenshot of what appeared on your computer at that time will appear on your desktop. Also if you disable F9, F10, F11, and F12 to as hotkeys to open the dashboard (leopard and snow leopard OS only) or mission control (lion OS only) you are able to to take screenshots of the game by pressing F9 once you disable the hotkeys in system preferences. press F12 before that to remove all HUD elements such as your health bar from the screen.
