Today I was helping to set up an older G4 15" MBP that my brother gave to my dad and I went to use both fingers to scroll just like I do all the time on my intel 15" MBP and was shocked to see that the feature didn't exist in the mouse/keyboard settings. I just assumed that feature was always there with the MBP line for some reason. I did a google search and noticed there was some hack to allow for it, but the file to download was no longer available. Does anybody know anything more about this? Just trying to make my dad's first apple experience as pleasant as possible.
