Why would you set alarm on Mac when you can easily do so with an iPhone? Well, it might be surprising, but people set alarms on their computers for various reasons. They want to be alerted of meetings, birthdays, or taking a break from their work.

Today, we're here to show you how to set an alarm on Mac. More importantly, we'll also explain how to set recurring reminders and schedule alerts with apps you don't usually find on your MacBook. Let's start. 

How to set one-time alerts on Mac

Setting MacBook alarm clock is easy if your computer runs on macOS Ventura or higher. There, you have a Clock app to set one-time or recurring alarms.

On older macOS versions, you can use the Reminder app, Apple Calendar, or ask Siri to set an alert. 

Alternatively, you can download third-party apps like Due, Dato, 2Do and others, which let you set alarms easily and access various productivity tools.

Regardless of the app you use, we'll show you how to set alarms on your MacBook easily with the steps below. 

Setting alarm on Mac with the Clock app

Setting a one-time Mac clock alarm is the answer when you need a timely alert, for example while taking a break at work.

  1. Open the Clock app. 
  2. Click on the Alarm tab at the top. 
  3. Click the + icon at the top right to set a new alarm.
  4. Set the time, description, and tone for the alarm.
  5. Click Save.

  1. Open the Calendar app.
  2. Double-click the date that you want to set an alarm.
  3. Click on the timeline, find the Alert and choose when you want to be reminded of the event.

How to set a recurring alarm on your Mac

Some people bring their MacBook to bed — literally. If you do so, you can turn your Mac into an alarm clock that wakes you up every morning, for example, at 6:00 AM on weekdays.

Again, the Clock app, available on macOS Ventura or later, proves helpful. When setting the alarm, you can tap on the days you want it to ring. However, remember that you shouldn't let your MacBook go to sleep when you have an alarm running. To keep your Mac awake, go to System Settings > Battery > Options and turn on Prevent automatic sleeping on power adapter when the display is off.

Now, your MacBook will not automatically go into sleep mode when it's connected to the power adapter. This means you can set recurring alerts and know that they'll sound.

The Clock app is good if you want to set repeating alarms for weekdays. However, you'll need third-party apps to set weekly, monthly, or yearly reminders. 

For example, you can remind yourself of a friend's birthday with Due

  1. Download and open Due.
  2. Click on the + button at the bottom left corner.
  3. Fill in the title. For example, "Jane's birthday". 
  4. Select the date and time. 
  5. Click Repeat > Custom > Yearly and choose Every 1 year. 
  6. Press Save to confirm and save the settings.

Due keeps reminding you of the event at the specified date and time until you turn it off. 


How to create Mac alarm shortcuts 

It's great to quickly access reminder apps instead of searching for one in Finder to set a new alarm on your MacBook. Here's a simple trick to do it with the Shortcuts app using the Clock as an example. 

  1. Open Shortcuts from Launchpad.
  2. At the top menu, click on +.
  3. On the right pane, switch to Apps.
  4. Choose Clock > Add alarm and set it up.

    Create an Alarm

  5. Close the current window to go back to the previous menu. 
  6. Drag and drop a new shortcut to the left panel to the Menu Bar.
  7. Reach your alarm shortcut in the menu bar and press it to set up the alarm in one click.

    Add Alarm

Alternatively, you can add shortcuts directly to Siri and state the action you want Siri to take. Then, Siri will launch the saved shortcut when it receives the correct instruction. For example, saying, "Hey Siri, Lungo" will put your screen to sleep while keeping the Mac awake. 

How to schedule events and tasks with alarms on Mac

Apple Calendar and Reminders are good for basic alerting, but they don't offer customizations, productivity tools, or other useful features that suit your work and lifestyle. If you need those, here are some third-party apps that might help.
