Big Sur is a big deal. The OS picks up where Catalina left off, further rationalizing Apple’s product lineup through design, new ways to bring apps to the Mac, and updates to existing system apps. The approach realigns functionality across Apple’s platforms after years of divergence from their common foundation: Mac OS X. The result is an OS that walks a perilous line between breaking with the past and honoring it, acknowledging the ways computing has changed while aiming for a bold future.
Big Sur also clarifies Apple’s Mac strategy, the contours of which began to emerge with Catalina. It’s a vision of a continuum of computing devices that offer a consistent, familiar environment no matter which you choose while remaining true to what makes them unique. In practical terms, that means a carefully coordinated design language and a greater emphasis on feature parity across OSes. Conceptually, it’s also an opportunity for macOS to shed the perception that it’s a legacy OS overshadowed by iOS and reclaim a meaningful place in Apple’s lineup for years to come.
