Magic mouse erratic mayhem!
My magic mouse is posssesed! it seems to be playing back a sped up record of mouse moves or has a virus. I searched and tried: restart, Pram reset, remove the com.apple.driver.AppleBluetoothMultitouch.mouse then restart. Tried a USB mouse same erratic result!. replaced batteries.
Restart with all USB unplugged and magic mouse turned off and bluetooth off, and tried the USB cord mouse. Seems to be working on USB cord mouse, retried the bluetooth magic mouse and get same erratic result, no control at all, but USB cable mouse works fine.
Cannot restore the magic mouse so I have it off and using a corded mouse.
