It appears the software update also enables the gestures on MacBook Pros? Can someone confirm?
It may. But it just might allow the Magic Trackpad to work and support the gestures, and not the old trackpads (the one with a separate button)
Does this mean we can get inertial scrolling now in the mid-2009 MBP's?
I'm not sure. But if you have a Mid 2009 MacBook Pro, does it show up in Software Update? If it does, download it, and let us know.
