- The last time there was this much upheaval in terms of non-compatible apps was when Apple stopped shipping Rosetta in Mac OS X 10.7 Lion. Rosetta was Apple’s tool for translating apps to run on.
- The new Find My app combines Find My iPhone and Find My Friends into a single, easy-to-use app that’s now available on the Mac. Use it to locate your friends and family, share your location, and find missing devices—even if they’re offline.
New User Interface
macOS 11 introduces a redesigned user interface that enhances usability and approachability, and provides greater consistency with iPadOS. Most existing macOS apps that use system-provided controls automatically adopt the new appearance. If your app has a custom appearance, visit the macOS Human Interface Guidelines to learn how to update your app so it continues looking great for users.
AppKit introduces a variety of changes to interface elements, including alerts, browsers, buttons, menus, search fields, segmented controls, and toolbars. For details, see AppKit Release Notes.
App Store Privacy Information
Privacy is at the core of the entire macOS experience, and new privacy information in the Mac App Store gives users even more transparency and control over their personal information. Later this year, the Mac App Store will help users understand apps’ privacy practices, and you’ll need to enter your privacy practice details into App Store Connect for display on your Mac App Store product page.
Widgets
Widgets give users quick access to timely, at-a-glance information from your app in the macOS Notification Center. macOS 11 offers a redesigned widget experience. Your app can present widgets in multiple sizes, allow user customization, include interactive features, and update content at appropriate times. To learn about designing widgets, see the Human Interface Guidelines. To learn how to support widgets in your app, see the WidgetKit framework.
Mac Catalyst
Apps built with Mac Catalyst automatically adopt the new look of macOS 11 and make full use of the native screen resolution of Mac. macOS 11 has new and improved APIs for keyboards, menus, toolbars, color panels, and more, giving you greater control over the look and behavior of your app. To learn how to get full control of every pixel of the interface and Mac-specific controls, such as pull-down menus and checkboxes, see Choosing a User Interface Idiom for Your Mac App. To learn more about building Mac versions of your iPad apps, see the Mac Catalyst documentation.
Machine Learning
Your machine learning apps gain new functionality, flexibility, and security with the updates in macOS 11.Core ML adds model deployment with a dashboard for hosting and deploying models using CloudKit, so you can easily make updates to your models without updating your app or hosting the models yourself. Core ML model encryption adds another layer of security for your models, handling the encryption process and key management for you. The Core ML converter supports direct conversion of PyTorch models to Core ML.
The Create ML app’s new Style Transfer template stylizes photos and videos in real time, and the new Action Classification template classifies a single person’s actions in a video clip. The Object Detection and Word Tagger templates have new transfer learning options to approve model accuracy when training data is limited. Training control helps you explore models and interact with them during model training. And ML Compute takes advantage of GPUs to accelerate training on the Mac. For more information, see the Core ML,Create ML, and ML Compute developer documentation.
Vision
With macOS 11, the Vision framework has added APIs for trajectory detection in video, hand and body pose estimation for images and video, contour detection to trace the edges of objects and features in image and video, and optical flow to define the pattern of motion between consecutive video frames. To learn more about these features, see the Vision framework documentation. In particular, read Building a Feature-Rich App for Sports Analysis to find out how these features come together in a sample app.
Natural Language
The Natural Language framework has new API to provide sentence embedding that creates a vector representation of any string; word tagging to train models that classify natural language, customized for your specific domain; and confidence scores that rank the framework’s predictions. For more information, see the Natural Language framework documentation.
SwiftUI
SwiftUI provides a selection of new built-in views, including a progress indicator and a text editor. It also supports new view layouts, like grids and outlines. Grids and the new lazy version of stacks load items only as needed.
Starting in Xcode 12, you can now use SwiftUI to define the structure and behavior of an entire app. Compose your app from scenes containing the view hierarchies that define an app's user interface. Add menu commands, handle life-cycle events, invoke system actions, and manage storage across all of your apps. By incorporating WidgetKit into your app, you can also create widgets that provide quick access to important content right on the iOS Home screen or the macOS Notification Center. For more information, see App Structure and Behavior.
Safari Web Extensions
Users can customize Safari with new functionality and features by adding your extensions. You can now leverage Safari Web Extensions inside Safari and access migration tools that make it easy to convert popular extensions for other browsers to Safari. Safari extensions also give users privacy control — they can decide which sites an extension can work with and give it access just once, all day, or all the time. The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts.
Family Sharing for In-App Purchases
Family Sharing is a simple way for users to share subscriptions, purchases, and more with everyone in their household. And with macOS 11, you can choose to offer Family Sharing for your users’ in-app purchases and subscriptions so their whole family can enjoy the added benefits. See the SKProduct and SKPaymentTransactionObserver for the new APIs.
Uniform Type Identifiers
Use the new Uniform Type Identifiers framework to describe file formats and in-memory data for transfer, such as the pasteboard; and to identify resources, such as directories, volumes, and packages.
Accessibility
A new Accessibility framework lets your app dynamically deliver a subset of accessible content to a user based on context.
File Compression
Use the new Apple Archive framework to perform fast, multithreaded, lossless compression of directories, files, and data in macOS.
Screen Time
macOS 11 includes Screen Time APIs for sharing and managing web-usage data and observing changes a parent or guardian makes. For more details, see the Screen Time framework documentation.
macOS is the operating system that powers every Mac. It lets you do things you simply can’t with other computers. That’s because it’s designed specifically for the hardware it runs on — and vice versa. macOS comes with an entire suite of beautifully designed apps. It works hand in hand with iCloud to keep photos, documents, and other stuff up to date on all your devices. It makes your Mac work like magic with your iPhone and other Apple devices. And it’s been built from the ground up with privacy and security in mind.
Featuring all-new, dedicated apps for music, TV, and podcasts. Smart new features in the apps you use every day. And Sidecar, which lets you use iPad as a second Mac display.
Easy to Use When it’s simple to
do
everything, you can do anything.
On a Mac, everything is designed to work just the way you expect it to — from operating it with simple, intuitive gestures to asking Siri to find a file to having your apps automatically update themselves. Whatever you set out to do on a Mac, there’s much less to learn and that much more to accomplish.
The Finder lets you easily browse and organize the files on your Mac — and those stored in iCloud Drive. View files by icons, in a list, or with Gallery View, which helps you quickly locate a file by how it looks. Drag and drop files into folders in the sidebar. And use the Preview pane to see all of your files’ metadata, quickly create .zip files, and share using the handy Share menu.
Dark Mode adds a dramatic look to your desktop and apps that puts the focus on your content. Dynamic Desktop makes your Mac even more beautiful with time-shifting desktop pictures that match the time of day wherever you are. And Stacks keeps your desktop free of clutter by automatically organizing your files, images, documents, PDFs, and more into tidy groups.
Spotlight helps you quickly and effortlessly find what you want, like documents on your Mac, movie showtimes, and flight departure and arrival times. Just type a few keystrokes in the Spotlight search field and autocomplete immediately shows you relevant results.1
A simple two-finger swipe from the right edge of your trackpad brings up Notification Center — the same one you use on iPhone — where you can see all the alerts that have come in recently. It’s also where you’ll find your Today view, which you can customize with helpful widgets or handy information pinned from Siri searches.

Siri helps you get things done just by using your voice. It also helps you get more things done at the same time. So you can finish your document while asking Siri to tell your coworker that it’s on the way. Looking for the presentation you worked on last week? Just ask Siri.2 And with Apple Music, Siri can be your personal DJ and recommend music based on your tastes, and tell you more about songs, albums, and artists.3
Continuity All your devices.
One seamless experience.
Your Mac works with your other Apple devices in ways no other computer can. If you get a call on your iPhone, you can take it on your Mac. And when friends text you — regardless of the phone they have — you can respond from your Mac, iPad, or iPhone, whichever is closest. When you copy text or an image from one device, you can paste it into another with standard copy and paste commands. And with Sidecar, you can extend your workspace by using your iPad as a second Mac display. You can even unlock your Mac with your Apple Watch. No password typing required.
Privacy and Security We believe your data belongs to you. Period.
Everything you do with your Mac is protected by strong privacy and security features. That’s because we build data security into everything we make, right from the start.
Privacy. You trust our products with your most personal information, and we believe that you should be in complete control of it. We respect your privacy by enacting strict policies that govern how all data is handled. And when you browse the web, Safari helps prevent data companies from tracking the sites you visit.
Security. We design Mac hardware and software with advanced technologies that work together to help you run apps safely, protect your data, and keep you safe on the web. The new Find My app helps you locate a missing Mac that’s lost or stolen — even if it’s offline or sleeping. And Gatekeeper makes it safer to download and install apps from the Mac App Store and the internet.
Built in Apps Apps as powerful and elegant as your Mac. Because they’re designed for it.
With every Mac, you get a collection of powerful apps. They’re the same apps you use on your iPhone or iPad, so they’ll feel instantly familiar. They all work with iCloud, so your schedule, contacts, and notes are always up to date everywhere. And because they’re native apps — not web apps in a browser — they take full advantage of the power of your Mac to deliver the fastest possible performance and more robust features.
Media. Experience music, TV, and podcasts in three all-new Mac apps. Get all the news that matters from sources you trust, all in one place.4 Track the market and customize your watchlist.

iCloud All your stuff on your Mac.
And everywhere else you want it.
Every Apple app uses iCloud — it’s the magic behind the seamless experience you have with all your Apple devices. So you always have your photos, videos, documents, email, notes, contacts, calendars, and more on whatever device you’re using. And any file you store in iCloud Drive can be shared with friends, family, and colleagues just by sending them a link. iCloud Drive also lets you access files from your Mac on your iPhone or iPad. It’s all done automatically. Just like that.5
Accessibility We make sure that everyone is able to use a Mac.
macOS comes standard with a wide range of assistive technologies that help people with disabilities experience what the Mac has to offer, providing many features you won’t find in other operating systems. Voice Control lets users control their Mac, iPad, and iPhone entirely with their voice. And features such as VoiceOver, Accessibility Keyboard, FaceTime,6 and Text to Speech help everyone get more out of Mac.
Technology Advanced to the core.
macOS features powerful core technologies engineered for the most important functions of your Mac. Thanks to Mac Catalyst, you can now enjoy your favorite iPad apps on your Mac. With SwiftUI, developers have a simple way to build better apps across all Apple platforms with less code. Create ML gives developers a faster and easier way to build machine learning into apps. And support for virtual and augmented reality lets developers create immersive worlds for you to step into.
