Magic Mouse not scrolling or swiping even with OSX 10.6.3 ? I have an intel iMac with OSX 10.6.3 installed and when I replaced my mighty mouse with a new magic mouse, I only got basic functionality. When I tried to install the Wireless Software Update, the system told me I had a newer version already installed. I since learned that the software update was for previous OSX versions and that my version had the necessary software update included. So why does my Magic Mouse not scroll or swipe and why does my preference window not show the added functionality that I bought this mouse for?
