Hi All After 6 years my macbook battery is really past it’s use-by. The keyboard has become a sea of won’t-push-this-week-and-hard-to-get-a-keypush so I decided to get a new laptop, but of course it comes with catalena. I’ve been using high sierra and all my ports are good. Is catalena now stable enough to ‘just work’ or need I consider installing (say) high sierra. James
