I run HighSierra on both the Air 11" (mid 2012) and a Mini (2014 with 16GB RAM and i7 CPU), it feels fine, dunno what am I missing from not upgrading, the Air is an all purpose for web browsing, on the fly photo editing and email, the Mini is the machine hosting my photo archive and back in time the discussion was about if latest OSx version would fully support Adobe and other photo editors, since then I never really got interested into all of this but just wondering what am I missing from staying where I am.
Grazie
