How to Sync Google Calendar With iCal Using CalDAV

Apple iCal version 3.0+ has a built-in "Accounts" feature that allows you to sync Google Calendars (or any calendar using the CalDAV protocol) in iCal. Prior to this version you could only subscribe to individual Google Calendars. If you have more than one calendar in your Google account, one for personal and one for business, for example, you can access both of them with iCal. Not only can you view events in iCal, but you can edit them as well, and they'll sync with Google. Here is how to do it.

Things You'll Need

• Apple Mac Computer Running OS X 10.5+
• iCal 3.0+
• Google Calendar Account

Instructions

1. 

   Launch Apple's iCal from its icon in the dock.

2. 

   Click "iCal" > "Preferences" or use the keyboard shortcut Command-, (comma).

3. Click on the plus sign below the "Accounts" list to add a new account.

4. 

   Type in a description for this Calendar (aka Account).

5. 

   Enter in your Google Calendar username and password.

6. 

   Click the right arrow next to "Server Options" to expose the server address field.

7. 

   Type the following in the "Account URL" field, replacing "[e-mail]" with the email address you use with Google Calendar:

   https://www.google.com/calendar/dav/[e-mail]/user

8. Click the "Add" button below the Account URL field.

9. 

   Change the refresh interval by clicking on the drop-down box next to "Refresh Calendars." This will change the rate at which iCal and Google Calendars sync.

10. 

    Click on the "Delegation" option.

11. 

    Click the check boxes next to the calendars you want to sync with iCal. If you don't see any, and you definitely have more than one calendar set up in Google Calendar, hit the refresh button beneath the "Accounts I can access" box.

12. 

    Exit out of the Preferences by clicking the red sphere in the upper left. Now you should see your new calendars available beneath the name you specified in Step 5 and under "Delgates."
