Does MainStage work with the new M1 processor MacBook Air?

My issues definitely start with third-party applications both software-based instruments and software-based processors. There are also questions in regards to how the cores are divided up on this machine it’s drastically different than the internal machines. I do have a case open that will be addressed by Apple engineers

Yes, it definitely works on any M1 machine....it's an Apple application.

What kind of issues? I’ve read a lot of reports by people using MS on M1 machines and they’re extremely happy. Are your issues with MS or with third-party plugins?

I’m having lots of issues.
