thanks for the continued help. Much appreciated!
I’ve just attempted a clean install of everything and the current error I’m getting is: Error: Could not find or load main class sim.app.antsforage.AntsForage or Error:
Could not find or load main class sim.app.heatbugs.HeatBugs
I’m guessing this is a problem with the CLASSPATH or some missing libraries. I have all the suggested jars in the Build Path in Eclipse as suggested but guess I’m missing something.
Thanks again for the help,
Hi again Kurtis,
Could you please detail what "no luck" exactly means. It is hard to
help if it is not clear what is going wrong.

thank you for your help. Much appreciated.
I have followed your instructions, but I’m still unable to get any of the
samples (AntsForage, HeatBugs etc. [via right-click>run as>Java
application]) to work.
1. I have Java SDK 8 for Mac installed from here
2. I have Eclipse IDE for Java EE Developers, installed from here
3. I downloaded the MASON jar files (mason.18.jar) and the libraries
(libraries.zip) from the MASON website.
4. I created a new Java project in Eclipse and added the MASON jar to the
build path as well as the libraries jar files
I have all the recommended jar files in place and still no luck.
I have followed these instructions
(https://cs.gmu.edu/~eclab/projects/mason/docs/) and these instructions
for installing Java3D and still it does not work.
Does anyone have a link to a version of Java3D that does work with Mac OS X?
Can anyone provide a detailed guide to getting MASON up and running on Mac?
Can we work on a detailed installation guide here so others (I know there
are others who can’t get it set up and just give up) don’t have the same
problems as I am?
All the available instructions have you jumping back and forth from one link
to the next and have outdated, contradictory or confusing instructions (do
this, if that doesn’t work go here and see if that works, it may not so go
somewhere else and try this, it’s outdated but just do this to get it to

Our experience in my course this year was interesting. I am a PC user, but
many of the students had Mac laptops. We spent an enormous amount of time
trying various website tricks to get Java 3D to work. A couple of Macs got
it right just from the jars. Others did not. What worked for some did not
work for others, even with the same latest OS. I finally had to omit 3D from
the course. The online blogs also indicate variable results. I hope it is
easier next Spring. Perhaps some of the experiences of the Mason user-group

One of my colleagues recently installed MASON on a Mac to test some of

Like this you won't have 3D support but you'll be good to go for
Building 3D support for the Mac is a matter of grabbing a bunch of jar files
from the jogamp website, and dumping them in as well (see the MASON web page
for rough instructions).
