The operating system is named after the coastal region of Big Sur in the Central Coast of California, continuing the naming trend of California locations that began with OS X Mavericks. To mark the transition, the operating system's major version number was incremented, for the first time since 2001, from 10 to 11. It is also the first macOS version to support Macs with ARM-based processors. Most notably, macOS Big Sur features a user interface redesign that features new blurs to establish a visual hierarchy and also includes a revamp of the Time Machine backup mechanism, among other changes. īig Sur is the successor to macOS Catalina, and was succeeded by macOS Monterey, which was released on October 25, 2021. It was announced at Apple's Worldwide Developers Conference (WWDC) on June 22, 2020, and was released to the public on November 12, 2020. 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.MacOS Big Sur (version 11) is the seventeenth major release of macOS, Apple Inc.'s operating system for Macintosh computers. 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.

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.
