This little hack outlined on TUAW allows slightly older Mac laptops to use multi-touch gestures, including the beautiful four-finger swipe:
- MacBook Air (all models)
- Early 2008 MacBook Pro
- Late 2008 17" MacBook Pro
- Unibody MacBook (all models)
- Unibody MacBook Pro (all models)
I have an early 2008 MacBook Pro -- a refurbished 2.5ghz -- and this procedure worked without a hitch. I am now slightly less jealous of the awesome trackpad on the new MBPs... but only slightly.
