How to set alarm on Mac?
Whether you’re waking up for work or setting a timer for baking, your Mac can handle your timing needs efficiently.

From using in-built applications like Siri and Reminders to exploring third-party software, the options for using your Mac as an advanced alarm clock are versatile and cater to different preferences and needs.
1. Use the built-in Clock app
If your Mac is running macOS Ventura or later, the Clock app will be preinstalled on your system. It is a straightforward way to set alarms and timers.
It features an intuitive interface where you can quickly add and manage multiple alarms. Here’s how to use it:
- Open the
Clock
app from yourApplications
folder. - Click on the
Alarm
tab at the top of the window.

- To create a new alarm, click the
(+)
button on the right. - Set the alert time for your alarm and select repeat settings or alert sound as desired.
- Click
OK
to save the alarm, and make sure your Mac is on at the set time.

Remember, the alarm will only alert you if your Mac is awake, so consider adjusting your energy settings to prevent it from going to sleep if you’re relying on this alarm.
2. Use the Apple Calendar to set up an alarm
The Mac Calendar app doesn’t have a direct “alarm” feature like the Clock app, but you can set reminders or alerts for events at a specified time, which effectively works as an alarm.
Here’s a step-by-step guide on how to set an alarm-like event using the Mac Calendar app:
- Launch the
Calendar
app from theDock
orLaunchpad
. - Double-click on the desired date or click the
(+)
button. - Name the event (e.g., “Birthday”) and set the time.
- Set a repeat frequency under
Repeat
if needed. - Click outside of the event settings box to save the event.

3. Setting up an alarm using Siri
For those using macOS Sierra or newer, Siri offers a convenient voice-activated method to set reminders and alerts quickly:
- Activate Siri by clicking the Siri icon in your menu bar or using the voice command
"Hey Siri"
if enabled. - Simply say your reminder aloud, such as, “Remind me to attend the meeting at 3 PM tomorrow.”
- If you need to cancel or modify the reminder, activate Siri again and give the appropriate instruction, such as “Change my 3 PM reminder to 4 PM”.
While Siri cannot set a traditional alarm sound, it’s perfect for reminders that can integrate with your Calendar app and notifications.
4. Use the Reminders app for alerts and alarms
The Reminders app on your Mac can serve as an effective alarm tool, particularly for tasks and meetings.
Here’s how to maximize its features and set alarms:
- Open the
Reminders
app from yourApplications
folder. - Click on the
New Reminder
button or type directly into the list to add a reminder. - Click the
(i)
button next to your reminder to add details like times, dates, and notes. - Set a remind time for the entry to act as an alarm.

This Reminder app is excellent for keeping track of multiple tasks and can sync across all your devices with iCloud.

Why rely on your Mac to keep you on schedule?
Utilizing your Mac to manage your time and tasks offers undeniable convenience and efficiency.
Your Mac can seamlessly integrate all aspects of your life into one place, serving as a centralized hub for work and personal management.
Whether you’re tracking project deadlines or scheduling coffee breaks, your Mac’s native apps and third-party tools offer robust features to keep you organized without needing additional devices.
Additionally, aligning all your alerts and reminders on your Mac can enhance your productivity. By having reminders pop up on the screen you’re already working on, you’re less likely to miss important tasks or meetings, ensuring you’re always a step ahead.
Moreover, this method of organization is particularly beneficial for those who spend significant time on their laptops, making it a practical solution for managing time-sensitive responsibilities directly from your workspace.
The benefits of using your Mac as a planner
One major benefit of using your Mac as a planner is its accessibility. With your scheduling tools available on the same device you use for most of your daily activities, you can swiftly add or alter plans without shifting your focus away from your current tasks.
This streamlining of processes naturally boosts your efficiency and can significantly decrease the chances of overlooking important commitments.
Moreover, the integration capabilities with other devices via iCloud make it even more effective. Changes you make on your Mac’s calendar can automatically sync across your iPhone, iPad, or even Apple Watch.
This connectivity ensures that no matter the device you’re using, you’re always equipped with your latest schedule.
This interconnected system allows for a seamless transition between personal and professional life management, thus optimizing your organizational workflow.
How can you ensure you never miss an alarm?
To ensure you never miss an alarm on your Mac, it’s crucial to set up your device properly so that it remains active to execute alarms.
First, use the built-in Clock app for setting up recurring alerts or specific reminders.
Additionally, keeping a laptop Mac from entering sleep mode is vital when alarms are scheduled. Navigate to System Settings > Battery > Options
and enable the Prevent automatic sleeping on power adapter when the display is off
setting when plugged in.
This setting ensures that even if you’re not actively using your Mac, it won’t miss executing an alarm.

To ensure you don’t miss an alarm, consider adjusting your settings to prevent the Mac from sleeping at the time you expect the alarm to go off, as described above.
