To reduce interruptions on a Mac, start by quieting notifications from apps that rarely need an immediate response, then use a Focus to filter alerts during work periods. Keep only essential people, apps, and time-sensitive notices available. macOS also lets you change whether alerts appear on the desktop, make a sound, show a badge, or reveal a preview—so you can tune the kind of interruption instead of turning everything off.

1. Turn down notifications from low-priority apps

Open Apple menu > System Settings > Notifications and review the list under Application Notifications. Select an app and switch off Allow notifications if its alerts are not useful to receive as they arrive. That setting disables the app’s notification alerts; it does not remove the app or its messages. If you want to check those updates later, open the app directly or look in Notification Centre, where recent notifications may be available.

For apps you still want to hear from, adjust the alert style and sound instead of disabling alerts. Depending on the app, macOS can show alerts on the desktop, in Notification Centre, or on the Lock Screen. Temporary alerts disappear after a while; Persistent alerts stay until dismissed. Turn off Play sound for notification if the sound is the main distraction, or Badge application icon if numbered Dock badges keep drawing your attention. Options vary by app. Apple’s Notifications settings guide describes these controls and their differences.

A useful first pass is to keep alerts that need prompt attention, quiet apps that can wait, and disable notifications that do not help you act. For instance, you might retain calendar alerts but turn off promotional or social app notifications. That is a personal sorting rule of thumb, not a macOS category or automatic classification.

2. Use Focus to filter notifications during a work period

Changing individual app settings is useful when you want an app to be quieter all the time. For a temporary boundary—such as writing, presenting, or concentrating—set up a Focus. Open System Settings > Focus, choose an existing Focus such as Do Not Disturb or Work, or select Add Focus to create a custom one. A Focus can silence all notifications or allow selected people and apps through. Apple’s guide to setting up a Focus on Mac documents these options.

Select the Focus you want to customize. Under Allowed People, choose whether to allow notifications from selected contacts or silence specific people. Under Allowed Apps, choose Allow Some Apps to let through only a short list, or Silence Some Apps to block selected apps while the Focus is active. The labels and available controls may vary with macOS version. Choose a small set based on what genuinely needs to reach you during that activity; allowing every app defeats the filter.

Decide whether time-sensitive alerts should pass through

Some notifications, including certain Calendar alerts, can be marked time-sensitive. To allow them during a Focus, enable Time Sensitive Notifications in that Focus and make sure the relevant app is allowed to send time-sensitive alerts in Notifications settings. Both controls matter: allowing time-sensitive notifications in a Focus does not override an app-level setting that blocks them. If a particular reminder must reach you, check both places. Apple explains this two-part setup.

Apple also documents critical alerts as a separate app-level option. For example, Home can use them for some accessory alerts, and they can appear even when a Focus is on. Do not assume that a Focus silences every possible alert; review the individual app’s settings if a particular alert needs different handling. Apple’s Notifications settings guide describes critical and time-sensitive alerts.

3. Set Focus to turn on when it fits your routine

In the selected Focus, find Set a Schedule and choose Add Schedule. Apple documents time-based schedules, which use selected start and end times and days, and app-based schedules, which activate when you open a selected app. An app-based Focus turns off when you close that app or switch to another app. A location-based schedule is also available, but requires Location Services. Pick the trigger that matches the boundary you intend to create; a schedule applies the Focus automatically, but it does not decide which alerts deserve an exception. Apple’s Focus setup instructions.

For an immediate quiet period, turn on Do Not Disturb or another Focus from Control Centre in the menu bar. Choose the Focus there to turn it on or off. This is handy when you need to silence notifications now without creating a recurring schedule. Apple describes the Control Centre route in its Notification Centre overview.

4. Control previews, alerts while presenting, and catch-up

In System Settings > Notifications, use Show previews to choose whether notification content is visible Always, When Unlocked, or Never. This changes how much message content appears, which can help keep the desktop less revealing in shared spaces. It does not stop the notification itself. macOS also offers separate controls for showing notifications when the display is sleeping, when the screen is locked, and when mirroring or sharing the display. For a presentation, set the sharing option to Notifications Off if you do not want alerts appearing on the shared display; Apple documents this specific control in its Notifications settings guide.

Notification Centre is the place to review alerts you did not act on as they arrived. Open it by clicking the date or time at the top-right of the menu bar, or by swiping left from the right edge of the trackpad with two fingers. Notifications are listed there, and available actions vary by app. Some alerts can be cleared or handled from the notification itself. Apple’s Notification Centre overview explains how to open it and interact with notifications.

5. Check the result and adjust the exceptions

After changing settings, use the Mac normally through a work period and notice which alerts still interrupt you and which you later wish you had received. If an app remains noisy, revisit its alert style, sound, or permission. If Focus suppresses something you rely on, check the allowed people and apps list, the time-sensitive options in both settings locations, and whether the Focus schedule is active. These steps follow from how macOS separates app-level notification controls from Focus filtering; they are a practical troubleshooting sequence, not a promise that every third-party app behaves identically.

Wallo can help organize open Mac windows and to-dos around a goal, with keyboard focusing. It is relevant after notifications are tuned if you also want to arrange the work already open on screen. Notification permissions and Focus remain macOS controls; Wallo does not replace them.
