by | Dec 31, 2023

Can you imagine life without alarms? Alarms help you get to work on time, catch your flights, arrive at church punctually, and prevent you from missing deadlines or forgetting birthdays. They even remind you when to take your medication. Alarms are essential for various things, and it’s almost impossible to live without them. On a Mac computer, you can set alarms for different activities like meetings, tasks, events, or anything that requires a reminder. There are popular methods people use to set alarms on their Mac. In this guide, we will explain how to set an alarm on Mac and introduce you to another useful tool that you should get right away. Let’s get started!

How to Set an Alarm on Mac?

Method 1. Use the Apple Clock app

The latest version of macOS, called Ventura, has a Clock app for Mac. With this app, you can easily set alarms and timers or use the stopwatch on your Mac. 

To add and enable an alarm, follow these steps after updating your Mac to macOS Ventura or a newer version:

  • Open the Clock app from Launchpad or the Applications folder.
  • Click on the Alarm tab at the top.
  • Tap the plus button in the top right corner.

  • Use your keyboard to enter the time for the alarm. Make sure to choose between AM and PM correctly. You can also set the alarm to repeat on certain days of the week. In the Label section, you can give a name to the alarm, and the Sound option lets you choose the alarm tone. Please note that you can’t use songs from the Music app as alarm tones on Mac. Finally, decide if you want to enable the Snooze function or not.
  • Once you’re done, click Save.

Congratulations! You have successfully added an alarm on your Mac. When the alarm time arrives, you will receive a notification in the top right corner of your Mac’s screen. From there, you can choose to Snooze or Stop the alarm. Unlike on an iPhone, you can’t stop or snooze an alarm from Mac’s Lock Screen.

To delete an alarm on your Mac, hover your pointer over the alarm tile and click the small “x” in the top left corner of the tile.


  • Make sure your Mac is turned on. If you set an alarm on a MacBook, don’t close the lid.
  • Avoid force-quitting the Clock app.
  • If your Mac is connected to a speaker or HomePod, the alarm sound will play through that connected audio device. Be cautious as it can be very loud. To lower the alarm volume, adjust your Mac’s volume using the keyboard buttons or the Sound slider in the macOS Control Center.

Method 2: Ask Siri to set an alarm

If you have a Mac with macOS Sierra or a newer version, you can use Siri to perform different tasks. However, Siri cannot set alarms because Mac doesn’t have a clock app. But don’t worry, Siri can help you set reminders using the reminders app instead.

To use Siri, you need to enable it in your system settings. Here’s how:

  • Open System Preferences.
  • Click on the Siri icon.
  • Check the box that says “Enable Ask Siri.”
How to Set an Alarm on Mac?
  • In the pop-up menu, click the Enable button and close the window.
  • Click on the Siri icon in the menu bar.
  • Speak out the reminder you want. For example, you can say, “Remind me to call mom at 6 pm.”

  • If you want to remove a reminder, simply say “Delete” followed by the title of the reminder.

Now, you can call upon Siri and simply say, “Set an alarm for 5 AM.” Siri will understand your command and proceed to set the alarm as requested. Also read How to Use ChatGPT with Siri on iPhone.

Method 3: Set the alarm using a Third-party App

If you’re looking for an alarm/timer apps for your Mac, here are some free options available on the macOS App Store:

No.App NameDescriptionLogo
1Wake Up TimeAllows you to set an alarm on your Mac. Although not updated recently, it functions well on macOS Monterey and earlier versions.Wake Up Time

4Howler TimerA simple app that lets you set a timer on your Mac. When the timer ends, your Mac emits a howling sound like a wolf. The sound effect is impressive.Howler Timer
5HoroA time management app that allows you to set timers on your Mac. Resides in the Mac’s menu bar and plays a sound when the timer expires.Horo

Among all the above apps, we have chosen Wake Up Time. Here’s how you can set an alarm on your Mac using Wake Up Time:

  1. Open Wake Up Time on your Mac and go to the Alarm Time section. Set the desired time by using the small arrows or typing it in with your keyboard.
  1. In the Sound section, choose an alarm tone. You can click the play button to preview the sound. I personally prefer the Cosmic tone.
  1. Click the round alarm on/off button located at the bottom left to activate the alarm. Once it’s turned on, you’ll see the text “Alarm set” in the light orange indicator box. The alarm will ring and play the selected sound to wake you up at the set time.

Important points:

  • The Wake Up Time alarm app (as well as other app methods mentioned in this guide) will only work if your Mac is awake. To address this, you can follow certain methods to prevent your Mac from sleeping. Alternatively, Wake Up Time offers an optional helper application that puts your Mac to sleep and wakes it up when it’s time for the alarm. To obtain the helper app, click on the “(i) > Download” option within the Wake Up Time app. Before installing the helper app, make sure to read through the FAQs on the app’s webpage.
  • When you unzip the file and double-click to open it, your Mac may display a warning about installing the helper application since it hasn’t been updated since 2013 and Apple can’t verify the developer. If you still wish to proceed, you can open apps from unidentified developers on a case-by-case basis by going to System Preferences > Security & Privacy > Open Anyway.

Method 4: Using the Apple calendar

The Apple calendar is where you can manage your schedule. To set a one-time alarm, follow these steps:

  • Open Launchpad to access the menu.
  • Click on the Calendar app.
  • Double-click on the date when you want to set the alarm.
  • Right-click on the desired time slot and select “New Event.”
How to Set an Alarm on Mac?
  • Enter the name of the event.
  • Go to the Date and Time section.
  • Set the alarm time.
  • Click on “None” to choose the alert type.
  • In the pop-up menu, select “Custom,” then “Message,” and click on “Message With Sound.”
  • Choose how many minutes before the event you want the alarm to go off, and click OK.
  • The alarm you set in the Apple calendar will sync with your iPhone or iPad, so even if you’re away from your computer, you will still receive an alert.

Method 5: Set an online alarm

You can now set an alarm on your computer using different websites. 

Here are some of the best websites to set an online alarm:

Just go to any of the recommended sites. Simply choose the desired alarm time, start it, and make sure not to close the browser tab or put your computer to sleep while waiting for the alarm. Most of these websites will still work even if your computer is offline after setting the alarm.
