Calaboration makes it easy to set up iCal to view and edit your Google Calendar calendars. It automatically finds all of your calendars and allows you to add any of them to iCal with the press of a button.

Due to limitations in iCal's CalDAV support of read-only calendars, Calaboration will not allow adding them to iCal by default. To add read-only calendars despite the limitations, you can enable them from Calaboration's preferences.

Calaboration requires OS X 10.5 or later (since iCal does not support CalDAV prior to 10.5).

NOTE: Calaboration is only a set up tool, and isn't part of the actual sync process. For any issues related to anything beyond getting the calendars to appear in iCal, try the Google Calendar Help group.
