Matt, Thank-you so very much for your work with this. I thank my lucky stars that there are decent people like you who go to this kind of trouble to help others with things like this. Do you have a way I can gift you a coffee or something?

I'm thinking of doing the same. Either that or buying another computer (windows?) specifically for the purpose of being able to continue to use my expensive hardware. Very frustrating, and tone-deaf on Apple's behalf. So far, no one has come back to me on many different forums to explain why this had to happen. What the reason was to remove something that worked fine in previous versions of the OS, but now have been deliberately removed.
