Mac and glass surface
Does the magic mouse work on glass surface
iMac
Question marked as
The Magic Mouse and other optical mice depend on a reflective surface to track movement. Glass will not work well if at all. however most desktop surfaces work fine. I prefer using a mouse pad for my purposes because I like the feel better.
