Sync contacts with OSX

Hey. I wrote a tutorial for my users to use contacts with their Nextcloud and OSX. But it doesn’t work!

I get this error:

See my tutorial below. What am I missing?

This is Work in Progress. The tutorial does not work yet.


Sync the macOSX Contacts App with the Nextcloud cloud.

This will allow you to check, update and remove your contacts from any computer with an internet connection. Also it will enable syncing contacts with your smartphone and/or tablet. Once it runs, and nothing breaks, you’ll forget it is there.


  • Your Nextcloud login name
  • Your Nextcloud password
  • An Apple computer with OSX (10.8 - 10.11.6) installed
  • A working internet connection
  • 15 minutes

Set up Contacts Syncing.

  1. Click on the Apple icon in the top left of your screen.
  2. Open the menu item ‘System Preferences…’.
  3. Click on the icon with the name ‘Internet Accounts’.
  4. Scroll down in the right pane, until you can click at the bottom on ‘Add Other Account…
  5. Choose the fourth item from the top: ‘CardDAV Account

A window opens called ‘Add CardDAV account’

Use these settings:
Account type: Manual.
Username: your username
Password: your password
Server Address:

Click Sign In!

Now your calendar is added. If you now open the Contacts App, will show in the left column. You can change the name in the Contacts App preferences.

Any contacts you now add will be synced automagically to the Nextcloud servers.

(ps. these steps are virtually the same on iOS)
