You can use the default apps like Calendar and Reminders, third-party websites, or apps to set an alarm on Mac. Let’s start with the easiest. 

1. Set an alarm on Mac using the Apple Calendar

Calendar event alerts on Mac are subtle. You will see a notification in the top-right corner and hear a faint one-second sound. This is more like a timer than an alarm, but at times it can come in handy.

For example, you are working on your Mac and wish to be reminded to take food out of the oven after 2 hours. In this case, you may quickly create a Calendar event with an alert (alarm) by following the steps below.

2. Set alarm on Mac using Kuku Klok

Kuku Klok is a neat easy-to-use online alarm clock website with multiple sounds. What’s better is that you only need internet connectivity to set the alarm. After that, the alarm will ring even if your Mac isn’t connected to the internet. Here’s how to use it. Another excellent alternative to Kuku Klok is vClock.

3. Use a third-party app: Wake Up Time

Wake Up Time and Sleep Alarm Clock are two potent third-party Mac alarm apps that get the job done. In the steps below, I will talk in detail about the former. Pro tip: This app, too, needs the Mac to be awake for the alarm to work. However, to manage this better, Wake Up Time has a little helper application that puts your Mac to sleep and automatically wakes it up at the time of the alarm.

4. Create alarms on Mac using the Reminders app

Just like the calendar app, you can use Mac’s Reminder app to create alarm alerts. This, too, shows a notification and a one-second alert sound like calendar events.

5. Set an alarm in macOS using Siri (Workaround)

I mentioned the absence of inbuilt alarm functionality in the first paragraph of this post. This is reflected when you launch Siri on your Mac and ask it to set an alarm. Instead, it will offer you to set a reminder. If you like, you can go ahead with this. Please see the screenshot below. Conclusion! I believe the above methods answered your query. They are not as convenient as the alarm on iPhone or iPad. Nevertheless, they work, in case you ever need them. Have more questions? Please put them in the comments section below.
