MacOS Big Sur

macOS Big Sur Features


Experience Features of macOS Big Sur

  • Updated menu bar: The menu bar is now taller and more translucent, allowing your desktop picture to extend from edge to edge. Words lighten or darken based on the color of your desktop picture. And pull-down menus are larger, with more space between the lines to make everything easier to read.
  • Floating Dock: The redesigned Dock is lifted from the bottom of your display and is more translucent, allowing your desktop wallpaper to shine through. And app icons are all-new and even easier to recognize.
  • New icons for apps: App icons have been redesigned to feel both familiar and fresh. Icons have a uniform shape but retain the stylistic touches and details that give Mac its character.
  • Lighter window appearance: Windows has a lighter, more spacious appearance that makes them cleaner and easier to work with. Additional translucency and rounded edges designed to match the radii of Mac create a cohesive look and feel throughout macOS Big Sur.
  • Redesigned sheets: Sheets in apps have been completely redesigned, removing borders and bezels to put the focus on your content. They automatically dim the background and scale into the center of the app.
  • New and updated sounds: System sounds are all-new and even more pleasing to the ear. The new system alerts were created using snippets of the originals, so they sound familiar.
  • Full-height sidebars: A new look for app sidebars make it easier to find what you want and gives you more space to get things done. Easily track your Mail inbox, access Finder folders, and organize Photos, Notes, Stocks, and more.
  • New symbols throughout macOS: New symbols in toolbars, sidebars, and controls bring clarity and consistency across apps, helping you immediately recognize where to click. When apps share common tasks — like viewing the inbox in Mail or Calendar — they share the same symbol. There are also localized versions of symbols with numbers, letters, and dates to match your system language.

Control Centre

Control Centre feature

  • Control Centre: Designed just for Mac, the new Control Centre consolidates your favorite menu bar items into a single place to give you instant access to the controls you use most. Just click the Control Centre icon in the menu bar and adjust Wi-Fi, Bluetooth, AirDrop, and other settings — without opening System Preferences.
  • Customize Control Centre: Add controls for the apps and features you use most, like Accessibility or Battery.
  • Click for more options: Click to expand the menu. For example, click Display to see options for Dark Mode, Night Shift, True Tone, and AirPlay.
  • Pin to menu bar: Drag and pin your favorite menu items to the top of your menu bar for easy one-click access.

Notification Centre

Notification Centre feature

  • Updated Notification Centre: A redesigned Notification Centre puts all your notifications and widgets into a single, dedicated column. Notifications are automatically sorted by most recent, and redesigned Today widgets deliver information at a glance.
  • Interactive notifications: Do more with your notifications on Mac for Apple Podcasts, Mail, Calendar, and more. Simply click and hold the notification to take action or get more information. Reply to an email, listen to the latest podcast, and even expand a Calendar invitation to see where the event falls in your day.
  • Grouped notifications: Notifications are grouped by thread or app. Expand each group to see earlier notifications. You can also disable grouped notifications if you prefer to see them individually.
  • Redesigned widgets: Experience brand-new widgets and beautifully redesigned widgets for Calendar, Stocks, Weather, Reminders, Notes, and Podcasts. Widgets also come in different sizes, so you can pick the one that works best for you.
  • Customize widgets: Easily add new widgets to the Notification Centre by clicking Edit Widgets. Then customize the size to show the amount of information you want to see and drag it into your widget list.
  • Discover more third-party widgets: Discover new third-party widgets for Notification Centre on the App Store.


safari feature of macOS Big Sur

  • Customizable start page: Customise the new start page to make it your own. You can set a background image and select new sections to display on the start page — including Favourites, Siri Suggestions, Reading List, iCloud Tabs, and even a Privacy Report.
  • Improved performance: Safari was already the fastest desktop browser — and now it’s even faster. Safari loads frequently visited sites 50% faster on average than Chrome.
  • Improved power efficiency: Safari is optimized specifically for Mac, so it’s more efficient than other browsers on macOS. Stream video for up to one and a half hours long and browse the web for up to one hour longer on a Mac notebook compared with Chrome or Firefox.
  • Favicons in tabs: Default tab favicons help you easily identify open tabs at a glance.
  • See more tabs at once: The new tab bar design displays more tabs onscreen at once so you can quickly move between them.
  • Website previews: When you just want a peek at what’s on a tab, hold the pointer over it to get a quick preview of the page.
  • Translation: Translate entire web pages in Safari. When you encounter a compatible page, just click the translation icon in the address field to translate into English, Spanish, Chinese, French, German, Russian, or Brazilian Portuguese.
  • Safari extensions on the App Store: An all-new extensions category on the App Store showcases Safari extensions with editorial spotlights and top charts, making it easier to discover great extensions from developers. All extensions are reviewed, signed, and hosted by Apple for your security.
  • WebExtensions API support: New support for the WebExtensions API and migration tools allows developers to bring Chrome extensions to Safari — letting you personalize your browsing experience with new Safari extensions from your favorite developers.
  • Grant extensions website access: Keep the websites you visit and tabs you use even more private. Safari asks you which websites a Safari extension can work with — and you can grant access for one day, or all the time.
  • Privacy Report: Safari uses Intelligent Tracking Prevention to identify trackers and help prevent them from profiling or following you around the web. A new Privacy Report shows how Safari protects your browsing across every website you visit. Go to the Privacy Report from your Safari menu and you’ll get an in-depth overview of every cross-site tracker blocked over the last 30 days.
  • Privacy Report for each website: See the privacy practices for every website you visit. Just click the Privacy Report button in your Safari toolbar for a summary of all cross-site trackers being blocked by Intelligent Tracking Prevention.
  • Start page Privacy Report: Add a Privacy Report to your start page — so every time you open a new window or tab, you can see how Safari protects your privacy.
  • Import passwords and settings from Chrome: Easily import history, bookmarks, and saved passwords from Chrome into Safari.
  • Password monitoring: Safari securely monitors your passwords, automatically keeping an eye out for any saved passwords that may have been involved in a data breach. If a breach is discovered, Safari helps you upgrade existing passwords and even generates secure passwords automatically. Safari keeps your data private and doesn’t reveal your password information to anyone — even Apple.


Messages feature

  • Pin conversations: Pin your favorite conversations to the top of your list. New messages, Tapbacks, and typing indicators animate right above the pin. And when there are unread messages in a group conversation, you’ll see the most recent participants circle around the pinned conversation.
  • Multiple pinned conversations: You can have up to nine pinned conversations that sync across Messages in iOS, iPadOS, and macOS.
  • Search: It’s easier than ever to search all your past messages for links, photos, and phrases. A new search experience for Messages organizes your results into links and photos and highlights matching terms. It also works great with keyboard shortcuts — just press Command-F to open.

  • Group photos: Set an image for your group conversations using a photo, Memoji, or emoji. Group photos are automatically shared with all members of the group.
  • Mentions: Direct a message to an individual in a group conversation by typing the person’s name or using the @ sign. And choose to receive notifications only when you’re mentioned.
  • Inline replies: Messages allows you to reply directly to a specific message in a group conversation. See all related messages in their own view to easily keep track of a thread.
  • Message effects: Celebrate special moments with balloons, confetti, lasers, and more. Or send a message loudly or gently, or even slam it. Send a personal message with invisible ink that remains blurred until you swipe over it with your cursor.
  • #images: Find trending images and GIFs, and quickly add them to any message. Discover popular memes when you open #image or search by keyword to find images relevant to your conversation.
  • Memoji editor: Easily create and edit a Memoji that reflects you. Choose from a wide range of hairstyles, headwear, facial structures, and other features to create one of over a trillion possible combinations.

  • Enhanced photo picker: Use the updated photo picker to quickly access and share your recent photos and albums.

  • Create your own guides: Create guides for all your favorite places, like “best pizzerias in Chicago”, or soon-to-be-favorites, like “sites to see in Paris”. Then share them with friends and family.
  • Look Around: Explore selected cities with an interactive 3D experience that lets you pan 360 degrees and move smoothly through streets.
  • Indoor maps: Browse detailed indoor maps of major airports and shopping centers around the world. Find out which restaurants are past security at the airport, where the nearest restroom is, or where your favorite store is at the mall.
  • Live updates for shared ETA: When friends send you a shared ETA, you can get live progress updates on the map so you’ll know when they’re expected to arrive.
  • New maps available in more countries: Detailed new maps are coming to more countries later this year, including Canada, Ireland, and the UK. See detailed roads, buildings, parks, marinas, beaches, airports, and more.
  • Congestion zones: Major cities like London and Paris have congestion zones to help reduce traffic in dense areas. Maps lets you see congestion zone tolls and even helps route you around them.
  • License plate restrictions: For cities in China that limit driving through dense urban areas, you can see if you have access based on your vehicle’s eligibility. Enter your license plate number to find out whether you can go through the city or need to reroute. License plate information is stored securely in Maps and never leaves your device.



  • Privacy information on the App Store: A new section on each app’s page on the App Store will help you understand the privacy practices of the app before you download it. It’s similar to the way nutrition labels help you understand what’s in the food before you buy it.
  • Self-reported privacy practices: Developers self-report their app privacy practices on the App Store. See the types of data their app might collect — like usage data, contact information, or location — and whether that data is shared with third parties.
  • Displayed in a simple format: Just as nutrition labels are convenient and easy to read, an app’s privacy information on the App Store is displayed in a consistent, simple format. This lets you quickly and easily understand the app’s privacy practices.

Software Updates

  • Faster updates: Once macOS Big Sur is installed, software updates begin in the background and complete faster than before — so it’s easier than ever to keep your Mac up to date and secure.
  • Signed system volume: macOS Big Sur introduces a cryptographically signed system volume that protects against malicious tampering. It also means that your Mac knows the exact layout of your system volume, allowing it to begin software updates in the background while you work.

In contrast to its predecessor, macOS Big Sur does introduce major innovations, which also work out well. The new design may be somewhat iOS-like, but it looks very sleek and, above all, tidy. This makes macOS ready for the future and that is also due to the other smart adjustments that make macOS better. All in all, Big Sur is definitely worth it and in our opinion an update that you should install immediately.
