Manage calendars and alerts

1 View active calendars

Click on ‘Calendars’ in the top-left corner of the Calendar app interface. This will display a list of all of your active/inactive calendars. The ‘active’ ones will be ticked.

2 Hiding calendars

If you don’t want to see a particular calendar, un-tick it in the sidebar. If you wish to unsubscribe, right-click on the calendar name and choose the ‘Unsubscribe’ option.

3 Limiting alerts

You can also hide the alerts of calendars by right-clicking on the calendar name in the sidebar and choosing ‘Get Info’. In the popup window, tick ‘Ignore Alerts’.

4 Stopping alerts

To mute events for certain calendars, go to Calendar>preferences>alerts and select an account from the top menu. You can now change the various event menus to ‘None’.

5 Tailoring alerts

Alerts for individual apps are also controlled through System Preferences. Click on ‘Notifications’, scroll down through the left sidebar and click on the ‘Calendar’ option.

6 Adjust options

Here you can change the Calendar alert style to ‘None’, or change it to ‘Banners’, which are much-less intrusive as they go away of their own accord before too long.
