But what can I use for Mac OS? I "Googled" ™ and found many free and paid programs to do screen recording. All of the free ones seem to only capture video and not allow audio. The ones that did both all seemed to cost money. I continue to search and then the answer arrived. You can do screen recording with QuickTime X, which comes with Snow Leopard. Here is how:
First, open up QuickTime X.

From the QuickTime File menu choose:

This brings up the Record button and options:
(Choose your audio source and where you want to save the file)

Then click on the record button.
This window pops up.

It tells you how to stop recording, by selecting Command-Shift-Escape. You will also see a Stop Recording button in the tool bar up top. See picture.

Once you stop recording, it will then bring the video into QuickTime Player where you can see the results of your handy work. Notice the VCR style buttons at the bottom of the video screen.

That's it.
