MACOS 10.16 Big Sur + Installation

Big Sur is a step in Apple's efforts to cohere its user experience across devices. Many of its "new" features will be familiar to owners of iPhones and iPads; it's playing catch-up to iOS. Big Sur, through a series of minor tweaks and refinements absolutely achieves the goal of making macOS look and feel more similar to iOS than it ever has before.
The headline feature is the redesign. The whole OS has a new look, which Apple says is its biggest design update to its desktop operating system since the debut of OS X. The company has made a number of tweaks that will sound small on paper but add up to an aesthetic that's friendlier, more modern, and much closer to iOS.
