Use VoiceOver to navigate notifications on Mac
Notifications appear in the upper-right corner of the screen. Depending on how options are set in Notifications preferences, you receive notification banners and alerts.
Banners are visible on the screen only briefly. When you receive one, VoiceOver says the name of the app (such as Mail) and a brief description (such as your name and the subject line of the email), but the VoiceOver cursor doesn’t move to the notification.
Alerts remain on the screen until you take an action. When you receive one, VoiceOver says Notification Alert while the VoiceOver cursor automatically moves to the notification; the cursor remains there until you take an action or navigate elsewhere.
Note: VO represents the VoiceOver modifier. See Use the VoiceOver modifier.
