Everything after Snow Leopard has been downhill in my opinion :3 macOS still my favourite unix but it started feeling is no longer my unix anymore, I'm just a glorified tennant.

My favorite was Mojave. Ran it way too long and I was 3-4 releases behind. Second fave was Panther, the good ol' days.

Never did much System 8 etc but we had it in school on one of the Mac labs.
