QuestionHow do I sync my Mac OS Calendar with the Wiki calendar(s)?

In the Calendar view, locate the calendar that you want to sync your iCal with (If you can't see it there then follow the instructions in How to subscribe to a Calendar (Wiki)).

Click on the chevron to the right of the calendar to see the drop down menu and choose Subscribe,

A dialog will appear with the link to the calendar.

Copy the link. This is the link you will use to subscribe to the calendar from outside the Wiki.

Now go to your Calendar app in Mac and choose File/New Calendar Subscription

and paste the link to the calendar into the dialog and click Subscribe.

Set the parameters (note: Auto-refresh defaults to Every week) for your Calendar app in the following dialog and then click OK.

Your Calendar app will now sync automatically to the Wiki calendar to which you subscribed.
