Cannot install artv1 maya 2017 mac (student edition)

from the documentation for mac install:

If you are using Maya 2017, the Maya scripts directory would typically be located in ~/Library/Preferences/Autodesk/maya/2017/scripts.

This folder doesnt exist. If i create the folder structure correctly and add the userSetup.py maya does not run the maya tools install dialog box.

i have also tried in:
users/shared/autodesk/maya/2017/scripts

If I browse to the file within the plugin manager i get error message:
// Error: file: /Applications/Autodesk/maya2017/Maya.app/Contents/scripts/others/pluginWin.mel line 767: (userSetup)

i also tried putting in either of the plugins folders:
users/shared/autodesk/maya/2017/plugins
users/shared/autodesk/maya/plugins

when I did this it show up in the plugin manager but when i click the loaded button i get error
// Error: line 1: (userSetup)

any advice would be really appriciated as the documentation doesnt seem to be up to date. thanks

I have found the answer now,

users/username/library/Preferences/autodesk/maya/scripts is the right location however is hidden. pres shift+cmd+full stop to unhide.

this is confusing as there is another path to a scripts folder on the drive that is not hidden as mentioned in the documentation at

Library/Preferences/Autodesk/maya/2017/scripts.

it really would be helpful to update the installation instructions to make it more clear as the paths are almost identical but refer to different locations. why maya needs so many scripts folders is confusing as well! thanks

I was able to find the hidden location. I still get following Error in Maya when running the script.

Error: line 0: IndexError: file line 21: string index out of range

Can you please help me with that? Also, I am using Maya 2018.

EDIT: Solution is restart of Maya

Alright… For everyone reading this, after you did what @dedbeat_ wrote, just restart Maya et voila, it’s working. When you change the menu to “Rigging” you’ll see A.R.T.1.0.
Thanks
