Haven't yet tried the toast 11 side of the application, but just to notify and please correct me if I'm wrong, but the cd spin doctor will crash mountain lion. I was told by Roxio tech support that it is incompatible with mountain lion and their developers have no plans as yet for an update. Moreover, apple states that if your machine came preloaded with mountain lion, you cannot downgrade to lion or leopard due to a software, firmware, hardware conflict. Mountain Lion has been out for ~6 months, time for Roxio to get their thumbs out and produce an update or even just a new version of toast/cdspindoctor. I buy an updated version if it is available.
