From the article: "It's important for professionals to be able to choose when and how they upgrade their software tools. With macOS, this is getting more and more difficult to do, and this is the main reason I want to leave the Mac ecosystem."
Of course, this is even more true of Windows 10, where Microsoft have decided they want to force updates on users on their chosen schedule - and of course just like with macOS, newer hardware can't run older versions of Windows. Have we reached the point where no major OS is suitable for actual, productive creative use?
OS X is still marginally better than the alternatives, but it's becoming increasingly flaky, and Apple's hardware support is a year or two short of a mass exodus to other platforms.
Win 10 is abhorrent in so many it's impossible to list them all. But it's increasingly usable and mostly stable. Some pro users can live with the horror. Others can't.
Linux is still a hobbyist, experimenter, and IT infrastructure OS. It's good at all the above, and it's being used for some creative pro applications. But it's not a straightforward option for anyone who just wants to get on with paid professional creative work.
It would be interesting if one of the main audio sequencers appeared on Linux. Bitwig is already there. But if (say) Ableton Live switched, it would start a mass stampede away from macOS.
Unfortunately Linux fragmentation makes that unlikely.
So - no, we do not currently have a rock solid no-nonsense OS for professional use, and it's looking less and likely that we'll have one any time soon.
