I bought a MM when I bought my MBP in 2012. I actually have been using the MM with my work Mac since the setup is just better for using that kind of pointing device. Recently, the mouse keeps disconnecting randomly, or never connecting to begin with. I've tried turning the mouse off and on, turning BT on the Mac off and on and even re-pairing but it still happens. Is this a sign of the thing dying? I turn the mouse off every night, and on in the morning.
