Adding Multi-Touch to older Mac Laptops

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.
