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
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
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.
Later this year, the Mac App Store will help users 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 beta and these resources to build apps for macOS Big Sur.
AdBlock for Safari is a fast and powerful ad blocking Mac app that speeds up web browsing by removing ads and reducing loading times of web pages. AdBlock starts blocking annoying ads on millions of websites from the moment you install it.
Interacting with the AdBlock for Safari Mac app
- AdBlock menu icon - located on the top menu bar - which has app information (version information & debug data), the ability to manage filter lists and quick access to allowlisted sites in AdBlock’s Settings window. This only displays when the AdBlock app is open.
- AdBlock browser icon - located on the Safari toolbar - where AdBlock can be paused, sites or pages can be allowlisted (i.e. “Allow ads”), quick access to the AdBlock Settings window and a link to AdBlock Help. This will appear even if the AdBlock app is closed.
- The AdBlock app icon - located in the Applications folder and/or on the Dock - this opens the AdBlock Settings window where AdBlock can be upgraded, filter lists can be managed and allowlisted sites (sites where ads are allowed to appear) can be added or removed.
Filter lists in the AdBlock for Safari Mac app
The Mac app uses Apple's Safari content blocking to block ads. In this respect, it's the same as our iOS app. Apple's content blocking mechanism doesn't understand the standard syntax that is used in standard filter lists. Instead, it uses a special content blocking syntax. Before a filter list can be used with the AdBlock app, it needs to be converted to the content blocking format. EasyList, Acceptable Ads, and Anti-Circumvention have all been converted.
You may find that AdBlock for Safari blocks fewer ads than AdBlock on Chrome, Firefox or Edge. This is because Apple imposes a 50,000 rule limit on the number of filter rules a content blocker can use at one time. While 50,000 sounds like a large number, in reality, it’s easy to run up against that limit with just a few filter lists. EasyList, for example, has more than 40,000 rules by itself. We could add more content blockers to the app, each with its own 50,000-rule limit but that adds significantly more complexity. Moreover, content blockers don't work well with each other, particularly when allowlisting rules are also being used.
There are three options for filter lists in the Mac app:
- Advanced ad blocking (i.e. Anti-circumvention filter list) -- available with the Gold upgrade
- Block annoying ads, pop-ups (i.e. EasyList filter list)
- Allow some non-intrusive ads (i.e. Acceptable Ads filter list)
To learn more about each filter list and how to subscribe to each, please see this article: Introduction to Filter Lists.
Manually updating AdBlock's filter lists
AdBlock's filter lists update themselves automatically when the app is open. Websites change their ads often, however, and it can be a day or so before the filter lists catch up.
