Bluetooth mouse not working after upgrade to Yosemite
I have an early 2014 Mac Pro. I'm using an Apple Magic Mouse with it, purchased around the time the Mac shipped at the beginning of May. I have another Mac and mouse combination nearby, but no other Bluetooth devices in the area.
Two days ago, I upgraded the OS from 10.9.9 to 10.10.2. Before the upgrade, I never had a problem with the mouse's connection dropping.
After the upgrade, the mouse started dropping its connection regularly. At first, it would restore right away. Each time, it took a bit longer to reconnect. Now, it won't reconnect at all.
What do I have to do to get these Apple products to work nicely with each other? At this point, I'll need to run out and get a wired mouse. If I don't Apple's own software upgrade will have bricked my very expensive machine...
