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.
All-new Interface
Mac Os 13 Beta
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
Separately, Apple also released macOS 11.3 beta 3 for Mac beta testers. IOS 14.5 and iPadOS 14.5 betas include some new features, like the ability to unlock an iPhone using an Apple Watch, dual SIM support for 5G, support for PS5 and Xbox X game controllers, additional privacy centric features, and a variety of new Emoji icons including a coughing emoji, a dazed face, a heart on fire, a woman.

Follow the instructions below to get started with the macOS Big Sur beta. If you've been waiting for macOS Big Sur to start testing with macOS, now's the time to start downloading.
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
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
The Mac App Store helps users better understand apps’ privacy practices. You’ll need to enter your privacy practice details into App Store Connect for display on your product page.
Tools and resources
Use Xcode 12 and these resources to build apps for macOS Big Sur.
Apple has made the third public betas of macOS Big Sur 11.3, iOS 14.5, and iPadOS 14.5 available for download.
Those who wish to participate can download the latest betas and configuration profiles from the Apple Beta Software Program. Subsequent changes for existing participants are available as over-the-air updates on enrolled devices.
The third developer betas of iOS 14.5 and iPadOS 14.5 contained a new tab in the Find My app for 'items.' This tab will be used for third-party tracking devices that use Apple's system and eventually will be populated by 'AirTags.'
Code strings discovered in the third developer beta of macOS 11.3 suggest that Rosetta 2 may be removed in some regions. It is not clear if this is a requirement by law or other issue.
AppleInsider, and Apple itself, strongly advise users don't install betas on highly-important or primary devices, due to the potential for data loss or other issues. Instead, it is recommended to install betas onto secondary or non-essential devices and to ensure there are sufficient backups of important data beforehand.
Find any changes in the new betas? Reach out to us on Twitter at @AppleInsider or @Andrew_OSU, or send Andrew an email at [email protected].
Update: Apple has also released a third version of the tvOS 14.5 beta to public testers.
