it seems like i have a very similar problem. So i just append to this thread.
I have a MacBook Pro Retina 15''- late 2103
MacOS Sierra - 10.12.5
NI Mate v.2.14 && NI Mate 2.13 osx_alpha
Kinect V2 for Windows (aka Kinect ONE, K4WV2..)
Asus Xtion Pro Live
I first installed v2.14 and was not able to run any camera at all.
It recognises the Kinect V2 but as status it keeps "Error, restarting in ..."
The log says:
12:10:43: Starting input 1: Kinect for Windows 2
12:10:43: Input 1: Creating QApplication

12:10:44: Input 1 crashed (view crash report)
12:10:44: Input 1 quit normally.
But there is no Crashlog.
It recognises the Xtion (OpenNI 2) but will stay "pending (Unknown error)" forever.
Also, the application will crash after a certain period - when Kinect V2 is connected to the Mac.
2.13 - osx_alpha recognizes and runs the Xtion without Problems (OpenNI 2) but fails when it comes to the Kinect V2.
(Won't recognise and "Install support for:..." fails, because no valid download link)
