Using the macOS Calendar Application


Postbox provides read and write integration with the macOS "Contacts" application, so Mac users can now keep all of their contacts in one location.

By default, new cards will be created in the macOS "Contacts" application. When reading a message from someone not in Contacts, click on the Contact in the message header envelope and click add contact from the Contact Panel. This contact will be added to your Contacts app. Click on the contact again and click edit to open the Contacts app and edit the card. Photos added to the Contacts app will appear in Postbox as well.

Here's how to get things set up: 

1) Enable Calendar App in macOS

Permission must be given to Postbox to use the macOS Calendar app. If you are unable to access your contacts within Postbox:

  • Open System Preferences > Security & Privacy > Privacy.
  • Within the panel on the left, scroll to the Calendars application and select it.
  • Within the apps panel on the right, scroll to Postbox and make sure that it is selected.


If you do not see Postbox listed in System Preferences > Security & Privacy > Privacy > Calendars you may need to reset your app permissions. Open a terminal window from your Applications / Utilities folder and then paste the following in, then press the return key:

tccutil reset All

2) Enable Date Detection in Postbox

By default, Postbox will attempt to use the macOS Contacts app, but if the integration isn't working for you, check to make sure this setting is enabled:
