macOS Big Sur takes the most advanced operating system in the world to a whole new level of power and beauty, and makes your apps look better than ever. Widgets and the widget gallery help you deliver more value to your users. Adding intelligence to your apps with machine learning is simple with extensive tools, models, training capabilities, and APIs. You can create more powerful Mac versions of your iPad apps with Mac Catalyst. And you can easily bring your extensions to Safari — and to the App Store.
macOS Big Sur brings a new design that’s been finely tuned for the powerful features that make a Mac a Mac. Core features, such as the menu bar and Dock, take advantage of the large Mac display, with translucent backings and spacious pull-down menus. The new Control Center, designed just for Mac, provides quick access to controls while keeping the menu bar clutter-free. Notification Center puts recent notifications and powerful new widgets together in a single view for at-a-glance information as you work. And a streamlined new design for apps features full-height sidebars and integrated toolbar buttons.
Easily build widgets using the WidgetKit framework and the new widget API for SwiftUI. Widgets now come in multiple sizes, and users can visit the new widget gallery to search, preview sizes, and add them to Notification Center to access important details at a glance.
