Setting up magic mouse
I have a new 'magic' mouse and although it works via Bluetooth to my mid-2011 27" iMac with OS X Yosemite I cannot customize it.
When I select Advanced in Mouse System Prefs the mouse is not recognized. Spinning icon only.
Any way I can customise this new mouse?
Thanks.
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
