Problems with Maya

I am having trouble installing Maya Rigging Tools. I am fairly new in Unreal Engine and am trying to find my way around using the tutorials.
I tried to install Maya using the instructions on the website except the only thing the “Maya_AnimationsRiggingTools” folder contains is a “P4Python.tps”. I don’t know what I should do.
If someone can help me out that would be great.
I am using Mac OS Sierra, and I am using the Unreal Engine 4.15.0.

Try looking for “ARTv1” in the marketplace. I think this replaced the thing they rolled out with the engine.
