Kinect doesn't work on the virtual machine or Mac.

I have "Kinect v2 Examples with MS-SDK" package and host OS for Win7 and Mac OSX. I created guest OS of Win 8.1 on the virtual machine on my both host OS, installed "Kinect for Windows SDK", and opened a demo scene in "Kinect v2 Examples with MS-SDK" package. Errors in console log in Unity didn't come out but my Kinect sensor doesn't work. I don't know why available is false.

It's like the following: (host OS: Win7, guest OS: Win8.1)

I've also tried libfreenect2 and "Kinect v2 Examples with MS-SDK" to be installed in my Mac OSX but my Kinect sensor doesn't work, either. It it possible to have it run on Mac OSX?

If it is the problem of the virtual machine and cannot run on Mac OSX, I may consider having Win8 installed in my Mac for another system.
