Now my big problem: how do i get this beauty working? what programs do i need? i don´t have any idea..

please help me out, i need it for an study exam at the end of this week :c

The first line it that source says python. You have that scripting language on your Mac already.

That source doesn't say anything about Kinect, but mentions MIDI. It looks to be a routine that you would include in some other code.
