What is striking about macOS 11.0 is the degree to which is feels more like a son of iOS than the sibling that Mac OS X was:

macOS 11.0 runs on ARM, just like iOS; in fact the Developer Transition Kit that Apple is making available to developers has the same A12Z chip as the iPad Pro.
macOS 11.0 has a user interface overhaul that not only appears to be heavily inspired by iOS, but also seems geared for touch.
macOS 11.0 attempts to acquire developers not primarily by being open and good, but by being easy and good enough.

It's a good look back at where macOS has come from - including the cringey funeral for Classic Mac OS - and where it's headed.
