Fix Notifications Not Working on Mac

If notifications have stopped appearing on your Mac, the fix is usually a combination of checking Focus modes, Notification settings, and restarting the notification center. Start by opening System Settings > Notifications, confirm that the specific app is allowed to send notifications, and then check if a Focus mode is silencing them.

Why Notifications Stop Appearing

macOS routes every notification through a central system called Notification Center. When that pipeline breaks, alerts can fail to show up even though the app itself is working. Common causes include:

• Focus mode is on – Do Not Disturb, Sleep, or a custom Focus can silently block all alerts.
• App-specific settings changed – The app may be set to deliver notifications to the Notification Center only, rather than as banners or alerts.
• Notification Center is full or crashed – A backlog of old notifications can prevent new ones from appearing.
• macOS bug after an update – Sometimes a system update resets notification permissions or introduces a temporary glitch.
• App is not running – Some apps only send notifications while they are open in the background.

Check Focus and Do Not Disturb First

Focus modes are the number one reason notifications suddenly stop. When you turn on a Focus, macOS hides all notifications except from people and apps you explicitly allow. To check:

1. Click the Control Center icon in the menu bar (the two toggle switches).
2. Look at the Focus section – if it shows a name like Do Not Disturb, Sleep, or Personal, click it to turn it off.
3. Alternatively, go to System Settings > Focus and review which Focuses are scheduled or active.

If a Focus is scheduled (for example, Do Not Disturb every night from 10 PM to 7 AM), notifications will be silenced during that window. You can also check if the Focus is set to allow notifications from certain apps only – that may be why one app’s alerts come through while another’s don’t.

Verify Notification Settings for the Specific App

Each app has its own notification style. Go to System Settings > Notifications, then find the app that isn’t sending alerts. You should see three delivery options:

• Alerts – appear on screen and stay until you dismiss them.
• Banners – appear briefly and disappear automatically.
• None – no on-screen display, but the notification still goes to Notification Center.

Make sure the app is set to Alerts or Banners, and that the toggle for Allow Notifications is on. Also check the Badge App Icon and Sound options – sometimes those get turned off accidentally, making it seem like notifications are broken when they’re actually just silent.

Restart Notification Center and the App

If settings look correct but notifications still don’t appear, the Notification Center process may be stuck. Restarting it is safe and often fixes the issue:

1. Open Activity Monitor (in Applications > Utilities).
2. Search for NotificationCenter in the search box.
3. Select the process and click the X button in the toolbar, then choose Force Quit.
4. macOS will automatically restart Notification Center within a few seconds.

Also quit and reopen the app that isn’t sending notifications. Some apps need to be fully restarted to re-establish their connection to Notification Center.

Clear Stale Notifications and Reset Permissions

A cluttered Notification Center can sometimes prevent new notifications from showing. To clear it, open Notification Center (click the date/time in the menu bar) and click the … button next to a group of notifications, then choose Clear All. If that doesn’t help, reset the notification permissions for the problematic app:

1. Go to System Settings > Notifications.
2. Select the app, then toggle Allow Notifications off and on.
3. If that fails, delete the app’s preferences file (usually in ~/Library/Preferences/ with a name like com.apple.notificationcenterui.plist) and restart your Mac – though this is a more advanced step, so back up first.

Update macOS and Check for Known Bugs

Apple periodically fixes notification bugs in macOS updates. If you’re on an older version, a known issue may be causing the problem. Go to System Settings > General > Software Update and install any available updates. After updating, restart your Mac and test notifications again. If the problem started right after a specific update, you can also check Apple’s support pages for that version – they often list known issues and workarounds.

When Notifications Still Don’t Work

If you’ve tried everything above, the issue may be with the app itself or with your Mac’s system state. Try these final steps:

• Restart your Mac – this clears many temporary glitches.
• Check if the app is set to “Do Not Disturbâ€� within its own settings – some apps have their own quiet hours.
• Test with a different app – if only one app fails, the problem is likely app-specific.
• Create a new user account – if notifications work there, your main account’s settings are corrupted.

If none of this works, you can reset the Notification Center database by deleting the notificationcenterui preferences and restarting, but that’s a last resort. For persistent issues, contacting Apple Support or the app developer is the most reliable path.

Frequently Asked Questions

Why are my Mac notifications not showing up even though they’re enabled?

This usually happens because a Focus mode is active, or the app is set to “None� for its alert style. Check both in System Settings – Focus and Notifications. Also make sure the app is allowed to send notifications in the Notifications pane.

How do I turn off Do Not Disturb on my Mac?

Click the Control Center icon in the menu bar, then click the Focus tile and select “Do Not Disturb� to turn it off. You can also go to System Settings > Focus and disable any scheduled Focuses.

Why do I get notifications on my iPhone but not on my Mac?

macOS and iOS have separate notification settings. Check System Settings > Notifications on your Mac to ensure the app is allowed there. Also, if you have “Allow notifications across devices� enabled in the app’s settings, it may be suppressing duplicate alerts – that’s normal behavior.

How do I reset all notification settings on my Mac?

There’s no one-click reset, but you can go to System Settings > Notifications and manually toggle each app off and on. For a deeper reset, delete the com.apple.notificationcenterui.plist file in ~/Library/Preferences/ and restart your Mac – this resets Notification Center’s database, but you’ll lose your notification history.

Why are my Mac notifications delayed?

Delays can happen if your Mac is in low power mode, if the app is not running, or if the system is under heavy load. Check that the app is allowed to run in the background and that your Mac isn’t in “Low Power Mode� (if you have a laptop). Also, some apps batch notifications – for example, email apps may only check every 15 minutes.
