Hi, I bought the newest 5k iMac which comes with the new Magic Mouse 2. It worked fine for the first 2 weeks or so, and then one day it started losing connection randomly, but would quickly reconnect. This was fine until a few days later when it would only connect if the mouse was directly under the screen, and I could only scroll up or down, very slowly. I followed the trouble shooting on the website, unplugged all of the USB devices, unplugged the system for a bit, reconnected, same problem. Tried restarted several times, removing the mouse from the bluetooth devices, re-synced it, same problem. So I called Apple, they sent me a replacement which I got today, worked great for 15 minutes, and now I'm having the same problem. What makes it really strange, is that the apple keyboard that came with my system has no problems, and even stranger, my previous magic mouse 1 works perfectly fine. The only bluetooth devices to have problems were the 2 new Magic Mouse 2's. Does anyone else have this problem? Could I have been unlucky enough to get 2 defective mice?
