I just opened and set up my new 20 Inch iMac less than an hour ago. The keyboard is strange, the mouse is stranger, so far I have managed to convince it I live in Tokyo and not Cupertino. That’s all I can report at this time.
Hey, Ronin.
Click on the black Apple logo in the upper left corner and select System Preferences. in the second row, select Keyboard and Mouse. Select the Mouse tab and check out the settings. If you are not getting a Right Button, you can turn it on here. You also might want to tweak the tracking, scrolling, and double click speeds while your there.
