I was given a new iMac at work to replace my aging MBP so I went through the migration process bringing over all of my documents and apps. Both machines are running 10.7.2. After it finished up I quickly noticed the new Magic Mouse doesn't perform any gestures. It's recognized in the bluetooth bar, points and clicks but that's about it. There are no options in system preferences to watch the gesture videos nor turn them on. Any ideas how to fix this issue?
