If you look on the content DVD yu will find a folder of tutorials.
Click on the html inside to start.
I realize that these are PC screen shots but LightWave is the same on both.
The only difference is install and configs.
For those visit http://www.newtek.com/3dact/downloads.php
Here you will find the most current configs and a doc for install on the Mac.
I hope this helps.
I am working on some Mac specific docs for the future.
