Applications
without unnecessary details
Full-height sidebars, updated toolbars. In the new laconic design of applications, nothing distracts from the main thing - from the content.
Updated Dock
A sleek new Dock design makes accessing your favorite apps even more convenient. Application icons are stylistically consonant with the icons of other devices, but at the same time retain their individuality.
Mac Control Center
Instant access to the controls you use most, such as Wi-Fi and Bluetooth, and new controls for listening to music and turning on Dark Mode. Designed specifically for the Mac, Control Center lets you add new controls and drag and drop commonly used controls to the menu bar to customize it to your liking.
Notification Center
Notifications and widgets can now be viewed in one window. Notifications are grouped by application. Many notifications have become interactive and let you, for example, turn on a podcast or find out more about invitations in Calendar. The updated widgets are presented in three sizes, and you can choose the one that suits you best.
