I came from a Linux background prior to getting into macOS so I'm not really a stranger to having to fix things myself, report bugs, or how to recover from crashes or other weirdness the public betas bring. I'm also intensely impatient about new features and exploring things, so while I've upgraded my production devices to beta software, that doesn't really make me worry about anything. As long as Safari and Pages still works I can get my writing done. Everything else is just nice-to-haves.
Presently running Sonoma on my M2 Air, iPadOS 17 on my iPad 8, iOS 17 on my iPhone 12, tvOS 17 on my ATV, and WatchOS 10 on my Watch SE. I dove right in there in other words. There is obviously some polish missing from certain elements of the OSes, the heartbeat monitor is flaky on WatchOS, setting up widgets on the iPadOS lock screen is very glitchy, and a couple other trivial things I've noticed are happening, but overall? Sonoma is a much more stable experience than most Linux machines I've used as daily drivers (except maybe Debian-Stable). I haven't experienced any runaway memory issues, battery drain, or thermal issues on any of the equipment I'm using.
Does Apple hire testers anymore? Think anyone could put a good word in with Tim? 🤣
