Mac App Day O

macOS Big Sur takes the most advanced operating system in the world to a whole new level of power and beauty, making your apps look better than ever on an all-new interface. New widget features and the new widget gallery help you deliver more value to your users. Adding intelligence to your apps with machine learning is even simpler and more extensive with new tools, models, training capabilities, and APIs. You can create more powerful Mac versions of your iPad apps with Mac Catalyst. And you can now easily bring your extensions to Safari — and to the App Store.

All-new Interface

Drafts is a launching-off point for text – use the actions to copy it, share it, or deep link into other apps and services. Compose a tweet or message, create a file in Dropbox, send a task off to Reminders – there are hooks into tons of your favorite apps.

  1. Explore the world of Mac. Check out MacBook Pro, iMac Pro, MacBook Air, iMac, and more. Visit the Apple site to learn, buy, and get support.
  2. Install any app with ease. The Mac App Store revolutionises the way apps are installed on a computer — it happens in one step. Enter the same iTunes password you use to buy apps and music on your iPhone, iPad, Mac or iPod touch.

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.

Widgets

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.

Safari Extensions

With support for the popular WebExtension API, it’s even easier to bring powerful extensions to Safari. Xcode 12 even includes a porting tool to streamline the process.

The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts to help users discover and download great extensions from the developer community.

Machine Learning

With macOS Big Sur, creating apps that leverage the power of machine learning is even easier and more extensive with additional tools in Core ML for model deployment, new models and training capabilities in Create ML, more APIs for vision and natural language, and improved resources for training on Mac and converting models to Core ML format.

Mac Catalyst

Day

Create even more powerful Mac versions of your iPad apps. Apps built with Mac Catalyst now take on the new look of macOS Big Sur and help you better define the look and behavior of your apps. You can choose to turn off automatic scaling of iPad controls and layout, allowing you to precisely place every pixel on the screen. Provide full control of your app using just the keyboard, take advantage of the updated Photos picker, access more iOS frameworks, and more.

User privacy on the App Store.
