Haven't found any real answers to this yet. For the past 2 (3?) years, annual 'named' MacOS updates have broken Rocksmith 2014 compatibility - followed by an increasingly long delay from Ubisoft to produce any kind of small patch to correct the problem.
With Sonoma having officially been released, I'm wondering if anyone in the community has made the upgrade and can confirm whether or not it breaks RS again? Been holding off for the moment, as it seems like Ubisoft may not bother to dedicate any resources to patching this year.
