Many thanks for that - it is the same problem in Windows as well, so deleted the post I made earlier as it's been answered here.
Like many others have said, this is going to be an issue for enterprise deployment, as including the Creative Cloud desktop app will make it want to launch when users log in (unless on Windows you remove certain registry keys).
I'd much rather go down the option of not having to add the Creative Cloud desktop app, so any further updates will be hugely appreciated.
