Google Calendar 與 Apple MACOSX iCal 同步

長久以來都是Google Service的愛用者，以往都是用Outlook 利用Oggsync同步Google Calendar

換了 Apple NB後，M$軟體已漸少使用

Google 並未遺忘了Apple使用者

iCal 也可以和Google Calendar 同步

操作方式如下


Enable Google Calendar in Apple's iCal

Only Apple iCal 3.x (on Mac OS X v10.5+) supports CalDAV sync.

To set up CalDAV support for Google Calendar in Apple's iCal, follow these steps:

1. Open Apple iCal, go to Preferences and then the Accounts tab.
2. Click on the + button to add an account.
3. Under Account Information, enter your Google Account username and password.
4. Under Server Options, add the following URL:
https://www.google.com/calendar/dav/YOUREMAIL@DOMAIN.COM/user

Replace 'youremail@domain.com' with your Google Account username.
5. Click Add.
6. Under the Delegation tab, select the calendars you'd like to add to iCal by checking the boxes next to them. You may need to hit refresh to get the latest list of calendars.
7. Add your email address to your Address Book card by selecting Add Email. You'll be prompted to add your email address only if your address is not already in your Address Book.

You won't be able to invite or email guests to Google Calendar events within iCal if your address is not in your Address Book.

Your Google Calendar will now appear in iCal's list of calendars, and changes you make to your Google Calendar in iCal will be reflected when you sign in to Google Calendar.

Event information will automatically refresh every five minutes. You can change this interval by opening the iCal > Preferences > Accounts menu and selecting a new refresh interval under the 'Refresh calendars' drop-down. Keep in mind you can also force a refresh by selecting a calendar and pressing the Apple and R keys at the same time.

Calendars that are checked but disabled have already been added to iCal - you can remove them from within iCal.

Enable Google Calendar in Mozilla Sunbird

Only Mozilla Sunbird 0.8+ supports CalDAV sync.

To set up CalDAV support for Google Calendar in Mozilla Sunbird, follow these steps:
1. Open the Sunbird application and select File > New Calendar.
2. Select On the Network and click Next.
3. Select the CalDAV format option.
4. In the Location field, enter [ https://www.google.com/calendar/dav/ [ your Google Calendar ID ] /events ] and click Next.

Your Google Calendar ID for your primary calendar is just your email address, but for all other calendars the Calendar ID will be in the form of [ long string of characters]@group.calendar.google.com. You can get the Calendar ID by clicking the down arrow next to your calendar at calendar.google.com and selecting 'Calendar Settings'.
Be sure to use https in your URL, as an http address will not work.

5. Enter a name and select a color for your calendar.
6. In the pop-up screen, enter the following information:

Username: This is the complete email address you use with Google Calendar (including the part after the @ sign). If you're using Google Apps, be sure to enter your Google Apps email address.
Password: This is the password you use to sign in to Google Calendar
7. Click OK.

Your Google Calendar will now appear in the Calendar tab of Mozilla Sunbird, and Sunbird will sync any changes to and from Google Calendar.
