As I recall, you need the Maxi-controller to set the primary address of the switch, then you can do everything else by computer. I'm referring to PCS, I don't know what Smarthome's computer program requires.

I use the PCS software which is a free download.

Click on "SceneMaster Setup Tool"

I don't know what's available for Mac, that's another world that I haven't even visited.

Programming any of the "scene capable" switches is a tedious job without a computer. It's worth getting set up for. My guess is that once you get your primary switch working, you'll start expanding to other areas. It's a bit addictive. The PCS switches work so well, they quickly become the "norm" for your house. My experience with Smarthome is that they are a bit less reliable. One product that Smarthome makes that is absolutely great and has no equal is the new BoosterLinc.
