I want to purchase a mashine jam with my mashine + will I have any issues and what’s the best iOS to run on the new Mac book pro?
iOS is for iPhones. MacOS is for Macs.
On the new M1 MacBook Pro the best OS would be the latest, Monterey, it comes pre-installed. (Or Big Sur).
Everything should work fine via Rosseta2.
