I recently replaced the worn-out mouse I use on my Mac with an Apple Magic Mouse. This is by far the best mouse I have ever used – so naturally, I wanted to get one for my Windows 7 machine. Apple does not officially provide Windows 7 drivers for it, but I found a solution that works perfectly.
First, I bought a Rocketfish Micro Bluetooth Adapter since my Windows 7 PC did not have BlueTooth built in.
Next, I downloaded the Magic Mouse driver installer from AnimGraph. This installer downloads Bootcamp 3.3, extracts the Magic Mouse Driver from the package, and installs the just the driver on a Windows machine. There is no need to install Bootcamp.
