Enable Magic Mouse Free-Scrolling in Leopard

You might have noticed the ability to scroll through web pages with the trackpad on the Magic Mouse in a way that is similar to the iPhone, iPod Touch and iPad.

It seems that Apple has only made this feature visible in System Preferences in Snow Leopard, but they have not added it to the interface on Leopard.

You can enable this kind of scrolling manually by typing some basic commands.

Simply start Terminal, and type the following (without quotation marks):

"defaults write com.apple.driver.AppleBluetoothMultitouch.mouse MouseMomentumScroll -bool yes"

After doing this, you might have to check and uncheck the Scroll option in System Preferences, and now you should have free scrolling fully enabled.
