These are instructions on how install and setup gesture based Multitouch on your MacBook Pro.
You can pinch, swipe, or rotate to zoom in on text, advance through a photo album, or adjust an image. The gesture-based input so successful on iPhone and iPod touch is now available on the MacBook.
Select System Preferences from the Apple Menu at the top left of the screen.
Select Keyboard & Mouse from the System Preferences window.
Select the Trackpad tab from the Keyboard & Mouse window.
Select the multitouch gestures you would like to enable from the list along the left side. I have selected them all for this tutorial.
