It's quite sad that frustration is seen as grumpiness. If it came over that was I will apologise, however, this was meant to be a ‘discussion’ in a bugs report thread. The thread was started back in December following another thread about any known issues in Sierra.
Richard, it's taken until now for a response (albeit a sarcastic one). I'm not blaming you for anything, I was simply trying to get a response so I could try and move forward. I have been trying to work out if it's an issue with my set-ups or if it's a common issue, or even possibly if it's an issue that would be looked into by yourself - this all came about as I went into purchasing new Mac book pros for touring overseas at the beginning of the new year. I'm kind of locked into the OS.

On the positive side , once Catalyst is up and running it's solid, it's just getting it there and it's only the mix mapping prefs thats an issue.
