Sorry old thread but maybe interesting. I am running a system with Apple silicon, my computer has the M1 Max and I would be happy to beta test. I use Ableton Live 11 and I can report that all my AU plugins automatically run through Rosetta and work as expected. I use Nimble Kick as an AU and it works well for me. If I want to run the VST version of the plugin I need to put Live in Rosetta mode, but there's no need to do that unless you specifically prefer to run the VST version.
