I'm not sure if you can say Macs just work anymore, and obviously this is the realm of people who like to tinker or make things work for the sake of the process. If only there was a word for it... Oh wait I think it's up up next to that Y up there :) The old hardware is pretty well supported in the Mac Pro because of how modular it remains. The majority of the incompatibility comes from not having a GPU that works with Metal. Those patch notes are mostly for devices with soldered components, like the GPU.
