Set up Maya rigging tool on Mac

Hello,
I’m trying to get the Mac Maya Rigging tools for Ureal engine to show up in the menus, but I cant figure out were the location should be for userSetup.pyo and the MayaTool folder
This is Maya 2013 on OSX10.8.5

I found mine in Applications/Autodesk/maya2013
and that worked when I put it there, but I had to rename the folder mayatools to MayaTools in order for Maya to recognize it.
