To the extent that it’s possible to do without final hardware in-hand, we’ll cover the new macOS features that will be native to Apple Silicon Macs and outline how the software side of the transition will go.

We’ll cover the operating system’s new look and new features-the things that any Big Sur Mac will be able to do, regardless of whether it’s running on an Intel or an Apple Silicon Mac.

We won’t be making any major changes to how we approach this review, either. This ought to be a smooth transition, most of the time. It may even be a bit less disruptive than Catalina was. 12 GB spare is barely enough for the OS to create and utilize swap space. Linux (/ l i n k s / LEE-nuuks or / l n k s / LIN-uuks) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Almost everything will still work the same way-or, at least, Big Sur doesn’t break most software any more than older macOS 10 updates did. Early betas were even labeled as macOS 10.16, and Big Sur can still identify itself as version 10.16 to some older software in order to preserve compatibility. Further Reading macOS 10.15 Catalina: The Ars Technica reviewīut unlike the jump from Mac OS 9 to Mac OS X, where Apple swept away almost every aspect of its previous operating system and built a new one from the foundation up, macOS 11 is still fundamentally macOS 10.
