Synchronizing with OS X
=======================

To use Nextcloud with iCal you will need to use the following URL::

    https://example.com/remote.php/dav/principals/users/USERNAME/

The setup is basically the same as with iOS using the path ``https://example.com/remote.php/dav/principals/users/USERNAME/``
to sync with Nextcloud. For OS X 10.7 Lion and 10.8 Mountain Lion everything works
fine, but OS X 10.6 (Snow Leopard) and older needs some fiddling to work. A user
contributed the following:

#. Make sure, "Addressbook" is not running. If it is, select the windows and press
Command + Q to terminate it.
#. Navigate to **/Users/YOUR\_USERNAME/Library/Application Support/AddressBook/Sources**.
If you already have some kind of addressbook set up, it is likely you will see
some folders named like this **BEA92826-FBF3-4E53-B5C6-ED7C2B454430**.
Note down what folders there are now and leave the window open.
#. Open "Addressbook" and try to add a new CardDav addressbook. At this point, it
does not matter what information you enter. It will come up with the same error
message you mentioned before when you click "Create". Ignore it and click "Create"
again. A non-functional addressbook will be added.
#. Close "Addressbook" again using Command + Q
#. Go back to the folder window from step 2. You will now see a newly created folder
with another long string as its name.
#. Navigate to the newly created folder and edit the **Configuration.plist** with
your favorite text editor.
#. Search for a section looking like this::

    <key>servername</key> <string>https://:0(null)</string> <key>username</key> <string>Whatever_you_entered_before</string>

8. Make it look like this. Please note that the :443 after **example.com** is important::

    <key>servername</key <string>https://example.com:443/nextcloud/remote.php/dav/principals/users/USERNAME</string> <key>username</key <string>username</string>

9. Save the file and open addressbook again. It will not work yet.

10. Open the preferences for your Nextcloud CardDAV-Account and enter your password.

11. You may have to restart addressbook once more. After this, it should work.

If it's still not working, have a look at the :doc:`troubleshooting` and
`Troubleshooting Contacts & Calendar`_ guides.

There is also an easy `HOWTO`_ in the forum.
