my iMac 27' late 2013 doesn't recognize my magic mouse, as magic mouse.
the mouse working and connecting by bluetooth, but his feature (fingers stuff) dosen't work.
something weird change since it's happend, while the icon of the mouse shows on the screen when it's connect change to the usb mouse shape and not like the magic mouse.
from my impresstion, it's seems the imac recognzie that there is mouse connected, but not the type of the mouse.
check out the attchtment pic.
i tried already to PRAM RESET
and SMC RESET
both didn't effect.
im lost.
