How to connect Kinect to unity 3D on Mac?

I am trying to use Zigfu to connect my Kinect to Unity on Mac. However, even after solving all the compiler errors, and running a sample scene the Kinect does not connect and I have an error that says:

MissingMethodException: bool UnityEngine.Application.get_isWebPlayer() UnityEngine.GameObject:AddComponent() ZigInput:get_Instance() Zig:Awake() (at Assets/ZigFu/Scripts/Zig.cs:32)

Help please :) Also, is there any other way I could connect Kinect to Unity on Mac? I am not able to download the Microsoft SDK so I can't use any of the available plugins on asset store! Thank you so much!
