The Mac OSx port of jit.openni is ready for a wider set of testing. You now have a native Max external that does not need any separately running applications or syphon to get your sensor (e.g. Kinect) data into Max. Now, the sensor data is directly in Max with rich functionality. You can write cross-platform patches!
Full doc and setup instructions are referenced in the README file and the wiki at https://github.com/diablodale/jit.openni/wiki
This is the same stable code as in the original Windows port; we made only slight changes to make it compile on OSx and included them back into the now cross-platform code for both platforms to benefit. If you find issues, please report them at https://github.com/diablodale/jit.openni/issues
Thanks to Stuart White of http://www.controlfreak.tv/ for jumpstarting the OSx port and helping isolate and test the needed changes. :-)
