Can't figure out how to install ARTv1 4.15.0 to Maya 2018

Hi there!

I downloaded the ARTv1 plug-ins from the Epic Luncher and installed it for Unreal Engine 4.21.1

On the help page, it says there should be a userSetup.py in the folder c:/Programs/Epic Games/UE_4.21/Engine/Extras/Maya_AnimationRiggingTools/MayaTools but it isn’t there… I only have a P4Python.tps in the ./Maya_AnimationRiggingTools…

Plus I can’t find the folder for Maya where I should copy it anyway.
I’m a Mac User that just moved to PC and I don’t quite understand how to find the ~/Library/Preferences/Autodesk/maya/ folder.

Can anyone help?
Thanks!

After looking a little bit more I finally found the solution there:

Sorry for posting for nothing, hopefully this could help someone else.
