For all of us struggling to get Toast Titanium 18 Pro and MyDVD Pro to work with the latest version of Catalina - this is what I have had from the chat line!
Sorry to inform. This is actually an ongoing issue and we currently do not have a fix for it yet. However, our Engineering team is already aware of it and are investigating. I am still waiting to hear back from them. I have no time frame as to when the issue will be resolved, but I will surely let you know as soon as I get word
