The problem is; When we make changes to iCal (change an event to
another calendar name for example), instead of iCal syncing with the
"central Google Calendar", the "central Google Calendar" also syncs
back to iCal and reverts the changes just made on iCal.
Is there a way to just sync one way? ie) From iCal to Google Calendar
only?
Thank you,
Jun
Sure. Don't use Spanning Sync :)
Publish your iCal calendar to a DAV server, tell GCal to fetch it from
there.
In iCal there is an option in the "Calendar" menu to "Subscribe..."
Choose this option and paste the address above into the dialog box
that appears. Now iCal will display the "Central Google Calendar,"
but users cannot modify the information on the Google Calendar page.
