There are two Magic Mouses in the house, and for the last few months they've both been choppy, and constantly disconnecting. I have to lift the mouse and click to reconnect about every two minutes. Is this a known issue with a solution? Or should I start shopping for another mouse? I really love the track pad aspect to the Magic Mouse and don't want to go back to a click wheel. It worked great for me for years. Is this a Yosemite thing?
