Your 15" MacBook Pro is almost perfect...but unlike its bigger sibling, the 17" MacBook Pro, the 15" variant does not have the fancy two-finger right click, which is a standar feature of the 17" type. Well those days are so over.

Apple Newton, an Apple Geek, recently made up a package installer that will replace your 15" MacBook Pro Trackpad driver with the current one that is shipping with MacBooks and 17" MacBook Pro models. According to him, once you run the installer and restart, you must go to your trackpad Preference Pane (within Keyboard and Mouse) and enable the right-click option to use it. (It is unchecked by default).

Also included in the package is an installer to restore the default 10.4.6 files in the event Apple requires them for future updates.
