Sierra is its own OS →

Dan Moren, on the next version of macOS:

No longer burdened by its increasingly dated X-laden moniker, the rebranded macOS got a major addition in the form of Siri, as well as some more minor improvements sprinkled throughout the OS.

But to me, the big message to take away from Monday’s presentation is that Apple is all too happy for the Mac to share features and technologies where it makes sense, but to still let it stand on its own two legs and be the best version of itself.
