OS X Calendar - view shared Google calendars I've been able to add a Google Calendar (CalDAV) account to OS X Calendar (v6, Mountain Lion 10.8.5) without problem, and all my own calendars show up.

Is there a way of seeing calendars others have shared with me (these show up under 'Other Calendars' in the Google Calendar website settings)?

(Same situation on my iPhone.)
