Bought a used Apple G4 Tower w/CD burner, with all programs uninstalled. CD Burner shows up in Extensions file. When I try to burn a CD, I get the message: "The burn operation could not be completed because the formatting application could not be found." What is it that I need? Roxio Toast? CD formatter? I'm a tyro to the max. Duh. Can you help?
