Enabling Java Web Start Applications for the Mac
Depending on the set-up of your computer, there are several things that must
be done in order to run the modules from this site.
Basically, Java needs to be installed, and then there a few clicks you
have to go through to run each module.
These instructions work when using the Safari browser version 11.1.2,
using the MacOS High Sierra (v. 10.13.6) operating system.
