I recently read that Adobe has released an M1 native version of Audition. When I download the trial and try install, it asks me to install Rosetta. I thought M1 native meant that you don't need Rosetta.
It could be that there is some sort of helper app that is not yet optimised. Adobe installs millions of little things one of which could potentially require Rosetta. When it’s install check to see if it native version in system profiler
