Sure, plenty of people use Windows for installations, even long-term/permanent ones! (myself included)
If you wanted to still develop/deploy on Mac, you could look at getting a basic PC to do the skeleton tracking and send out skeleton data over the network. There are some existing tools for this. If you went this route, make sure your PC still meets the minimum Kinect 2 requirements.
+ probably others
As a more experimental alternative, it looks like there is an open pull request for an OpenNI2 driver for libfreenect2, which ofxKinectV2 is based on. I would say it's possible to use OpenNI/NiTE for skeleton tracking, but it certainly is not an out-of-the-box solution and would require lots of hacking. But maybe you're into that sort of thing
