So, I got a Magic Mouse for Christmas. Which would be awesome, except that my MacBook won't recognize that it's a Magic Mouse. I installed the Wireless Mouse Update 1.0 from Apple and restarted my system (Snow Leopard 10.6.2, by the way). I then followed the instructions in the Quick Start guide for switching from a USB mouse to a Magic Mouse, which are as follows: 1) Slide the On/Off switch on the bottom of your Apple Magic Mouse to turn it on. No problems so far. 2) Choose Apple () > System Preferences, and then click Mouse. Still going fine. 3) Click "Set Up Bluetooth Mouse..." in the lower-right corner. Easy peasy. 4) Select your mouse, and then follow the onscreen instructions to pair it with your Mac. This is where the problems start. It shows up as "Apple Wireless Mouse," so I click the "Continue" button, but no onscreen instructions appear. It just kicks me back to the Mouse preference pane, with the same options as before. Aren't I supposed to get a pane with Magic-Mouse-specific options? Also, MagicPrefs doesn't recognize that there is a Magic Mouse connected. The mouse works, I can click and move the cursor and everything, but the system doesn't seem to recognize that it's a Magic Mouse. Any help is greatly appreciated. EDIT: Problem solved. I just had to uninstall USB Overdrive and everything worked perfectly.
