7.5 is in beta. If you are in beta, you should have been invited by Symantec. You can contact the Symantec beta representative for assistance. They'll grant you access to the beta site where there are beta videos and beta content on Mac imaging. In fact, there are quite a view videos on Mac imaging.
Due to the beta NDA I can't offer those here. You'll need to request them from the Beta Coordinator.
Does this answer your question?
