Hello Apple Support Communities I have used a Magic Mouse for some time, maybe now an year. But I started having this problem today. When the Magic Mouse did not connect with my MBP, I removed the mouse from the Bluetooth and tried to put it back. But the Bluetooth Setup Assistant is saying that the pairing did not work, and asked for a passcode or a different pairing method. Here's a screenshot: Also, I tried using the System Prefrences and click on mouse to set up my Magic Mouse, but it said the same thing; pairing failed. Here's a screenshot: Is there any solutions to this problem? I hope that you can get me an answer fast, as I use Magic Mouse a lot with my MBP. Screenshots will also be attached.
