Do I need to keep Calendar app open in order to be notified about calendar events I think this question can be very trivial, but for some reason it seems extremely difficult to find a clear and explicit answer to this.
If I close the Calendar app (by selecting &quot;Quit&quot;) and therefore its icon disappears from the Dock, is there still some daemon process running in the background and therefore I will still be notified about Calendar events? Or do I need to keep the app open?
For example, some apps like Microsoft Outlook must stay open in order to be notified about e-mails, therefore this is not necessarily something which is not needed to be said.
Ideally, is there any official or reliable source that says this? (e.g. official documentation)
Yes it does. If you set System Preference &gt; Notifications &gt; Calendar to Allow Notifications you should get a notification if you set the alert style to Banners or Alerts even if the app has been quit:
