Yes, I did read "Instructions for macOS". (Apparently the link in your initial answer here points to the answer for Windows.)
The method does work just fine.
Still puzzling why no paclet is on the github repository yet the docs on the project's page (and its readme file) describe the use of such!
Using paclets is a much handier means of installing things because one can subsequently use PacletUpdate
(or even PacletUninstall
) from PacletManager
.
