Fix Multi-Touch Trackpad Gestures on Mac Snow Leopard

It’s amazing how much I had come to rely on the motion to go forward and backward in web pages (swiping three fingers). Going back to having to “click” on the buttons suddenly seemed to be a major chore!

My MacBook’s multi-touch trackpad quit responding to the gestures after upgrading from Mac OS X 10.6.1 to 10.6.2. (At least I think it did; the functionality was broken for at least the last week or so…)

This blog post helped me to fix 3- and 4- finger gestures on my Mac’s multi-touch trackpad.
