I have this VTC training CD and it will not work on my G4 Mac, I can get it to work sometimes on my old G3 powerbook. I had to have instructions from their tech support people to get it to work, the instructions are a bit convoluted, but I have them, if you need them to get it to work on a Mac.
It is OK, but not great. I forgot how much I paid for it, but as I remember it was a bit expensive for what you got. It does have good basic PSE instructions though.
I haven't used it in a long time.
