Calendar: Set an alert for an event
You can be notified of a pending Calendar event by setting one or more alerts for it. Alerts can place a notice on your screen (using Notification Center), send an email, or perform other actions.
Set an alert for one event
- In Calendar, double-click an event, and then click Edit.
- Choose an alert from the Alert pop-up menu.
Message: Displays a notice on the screen (using Notification Center).
Message with Sound: Displays a notice on the screen and makes a sound (using Notification Center).
Email: Sends you an email. If you have more than one email address listed in Contacts, you can choose the one you want to use.
Open File: Opens the file you choose. If you don’t see the file you want, choose Other to select the file.
- Choose a time or date from the accompanying Alert pop-up menu.
- To add another alert, choose one from the next Alert pop-up menu.
Each time you set another alert, a new Alert menu appears. However, you can set only one alert for events on an Exchange calendar.
To remove an alert, choose None from the Alert pop-up menu.
Set an alert for all new events and birthdays
Any default alerts you set appear using Notification Center.
- In Calendar, choose Calendar > Preferences, and then click Alerts.
- Set the default alerts you want.
To add an alert to all new events, choose a time or day for the alert from the Events pop-up menu.
To add an alert to all new all-day events, choose a day for the alert from the All Day Events pop-up menu.
If you’re using the Birthdays calendar in Calendar and want to add an alert to all birthdays, choose a day for the alert from the Birthdays pop-up menu.
- To use these default alarm settings on only this Mac, select “Use these default alerts on only this computer.”
If you set a default alert before selecting this checkbox, you may continue to see the alert on other devices. To not see the alert on other devices, choose None, select the checkbox, and then choose a default alert.
