Toast = Digital media suite for Mac
Creator family = Digital media suite for PC (windows based system)
Do you currently own Toast 10?
Also if you have read the tutorial referring to Lightscribe, you would have noticed, you would require LSS (lightscribe system software) before you can use any application to use lightscribe abilities.
Toast 10 includes 3rd party labelling application that supports lightscribing if that is what you are asking.
