I haven’t tried the new OSX’s myself so I relied on info from the intetnet, sorry if I got it wrong. What sucks is that Apple keep on introducing new technologies only to immediately abandon them. They also always make sure that things aren’t backward compatible. I’ve been through Firewire 400, Firewire 800, thunderbolt 1, 2, and 3 and have ridiculous chains of adaptors and dongles to make my expensive peripherals (barely) function. Apple are IMHO needlessly waisting money and time for customers and for companies who develope peripheral equipment. They are also contributing to significant amounts of industrial waste despite of their environmental policies.
