What is Apple macOS Big Sur And What are The New Features Included macOS Big Sur

New features coming with macOS Big Sur.

macOS Big Sur brings a refined new design, powerful controls, and intuitive customization options to the most advanced desktop operating system in the world.

Key Features and Enhancements

Experience

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 have 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.

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 makes 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.
