Change Notifications preferences on Mac
On your Mac, use Notifications System Preferences to specify when you don’t want to be disturbed by notifications, and to control how notifications are shown in Notification Centre.
To change these preferences, choose Apple menu > System Preferences, click Notifications & Focus , then click Notifications. Select an app or website on the left, then view or change settings on the right. The options vary by app.
List of apps and websites
Customise notifications for an app or website.
To learn how to remove a website from the list, see Customise website notifications in Safari.
Turn notifications on or off. When you turn notifications off, the alert style and other notification options are dimmed.
Select a notification style:
Allow critical alerts
Let apps send critical notifications. For example, when you select this option for the Home app, notifications for accessories such as smoke detectors or door locks are always shown, even when a Focus is on.
Allow time sensitive alerts
Let apps send time-sensitive notifications. For example, when you select this option for the Calendar app, notifications for events that require your immediate attention are shown. To show these notifications when a Focus is on, you must also set the option for the Focus in Focus preferences. See Choose which notifications to allow.
Show notifications on lock screen
When you wake your Mac from sleep, show notifications you received while it was in sleep mode in the login window. See Put your Mac to sleep or wake it.
Show in Notification Centre
List recent notifications in Notification Centre. Notifications older than 7 days aren’t shown.
Badge app icon
Let the app show the number of notifications on its icon in the Dock. For example, Calendar shows a badge on its icon when you receive invitations.
Play sound for notifications
Let the app play notification sounds.
Show a preview in notifications for the app or website. For example, if you receive an email, a preview of the email is shown in the Mail notification.
Note: If you choose a setting from the “Show previews” pop-up menu at the bottom of the preference pane, it’s applied to all apps.
Choose whether and how notifications for the app or website are grouped in Notification Centre:
