(sorry I clicked post too fast

)
I just purchased a Kin 2 phone. In order to download pictures and videos I have to install something called "Zune" I hesitated to download it because it didn't specify that it's Mac compatible. I called their support and it said I can if I have OS X5 and above. I have 10.5.8. She said do I have Windows something or rather installed. (I couldn't quite understand her...foreign language)
Does anyone know if I have this Windows something or rather on my Macbook Pro? How do I check?
