Unfortunately I was on Monterey and downloaded a security update two days after Sonoma was introduced.My Mac Pro M1 silicon died and had to get it revived.As a result there was only one choice given by Apple and it was to install Sonoma only. My native keyboard doesn’t work and instruments won’t upload.Only positive is already recorded native instrument show and play back. what a pain it is.Apple technicians advised that you can’t go back as it wipes the computer of everything and you have to start again.Ok going forward.
