MayaStar 7.11 for Maya 2014 thru 2020 MAC

For Mac download and unzip file. Copy all files except the PyMEL folder or file inside it to your
Library/Preferences/Autodesk/maya/(YEAR of your Maya)/scripts.

Keep in mind that the Library folder is by default hidden from user. You have to either access the path directly in Finder from the menu or make the folder permanently visible (view options in user home directory if memory serves).

If you had Maya open when copying files close Maya and restart it.
