I've had my new iMac for about a month (first mac) and everything is pretty much working perfectly. The whole time, though, I have experienced my wireless Mighty Mouse disconnecting spontaneously. It just completely stops functioning and won't respond even if I turn if off, take out the batteries and put them back in, etc. I have since found out that I can get it to work again by going to the Bluetooth-menu in the menu bar via keyboard, disconnecting the mighty mouse (OS X still sees it as connected) and connecting it again. This has happened about 10 times or so within the month I have had the Mac, sometimes several times in a week, sometimes not at all for long periods of time. It still shows full battery, so that's not the cause, but what else could it be? Is this a known problem and if so, it is my mouse or my mac that's outta wack? Thanks in advance for your help!
