Yes it does. It is an excellent product.
I haven't tried this with a MAC but I can't see why it wouldn't. Also if you look on the Kensington website it says they do, check the attached link. http://www.kensington.com/kensington/en/gb/p/3243/33374EU/wireless-presenter-with-red-laser.aspx#.Uu69nbT8LKc

Sorry not sure Works on my laptop and my Desktop both have office 13 operating system on windows 7
have a friend and I am at a meeting with him on Wednesday so will try it on his mac air
The box says Mac compatible, but I'm not sure about a Mac air.
Hope this is helpful.
I can only say that it works on three laptops I have used, unfortunatly none are the Mac-air type.
