I’m specifically peeved about this. My personal 2016 mbp has nearly identical specs to my work 2017 mbp but my personal one is being left behind. Maybe there’s some minuscule hardware issue they couldn’t be bothered to work out but 5-6 years of OS updates is upsettingly short. I’d expect that for an android phone but not a high end laptop…

There does seem to be a dev working on porting over the OS if anyone has an earlier mac and really wants the new OS.
