Hi Andrew,
Unfortunately Mac hasn't been very consistent in their support of Java.
There are a few options:
1. If you have a Parallels partition you could just download the windows
version. I know Bob also has older versions that will work on windows.
2. You could try getting the new version to work via SoyLatte

3. You could also retool the Excel sheet from

Additionally, I have also coded parts of what the applet offers into
Matlab if that interests you.
Happy to help if I can.
Best,
Robert
