Frequently asked questions

Short answers to the questions we were asked most often about Spanning Sync.

What exactly does Spanning Sync sync?
Two things: your iCal calendars with Google Calendar, and your Address Book contacts with Google Contacts. Both directions, so an edit made anywhere ends up everywhere.
Is it a separate application?
No. Spanning Sync installs as a pane in System Preferences and runs in the background through Mac OS X Sync Services. A small menu-bar item shows sync status and offers Sync Now.
Do I need a Google account?
Yes. Any free Gmail account or a Google Apps account works. Google stores the shared copy of your calendars and contacts, which is what lets other Macs and phones see the same data.
Can I use it on more than one Mac?
Yes. Install Spanning Sync on each Mac and sign in with the same Google account. One license covered every Mac that synced with that account.
Does it work with the iPhone?
Indirectly, and well. The iPhone syncs with Google using Google's own mobile sync; Google then syncs with your Mac through Spanning Sync. Any other phone that can sync with Google works the same way.
What happens to events that already exist on both sides?
They are merged. When you pair an iCal calendar with a Google Calendar that both contain events, Spanning Sync combines them into one calendar instead of deleting either set.
How often does it sync?
Since version 2.0, right away whenever you change something in iCal or Address Book. A schedule you set in the Options tab also runs periodically as a safety net, and you can always click Sync Now.
What does not sync?
iCal to-do items and attachments, because Google Calendar has no place to put them. Those stay on your Mac. Alarms and attendee lists follow each service's own rules.
Was there a free trial?
Yes, 15 days of the full product with no credit card. Buying afterwards activated the copy you already had installed.
How much did it cost?
$25 per year, or $65 as a one-time purchase that never expired. Both included all features, updates and email support.
Which versions of Mac OS X are supported?
The final release, Spanning Sync 3.3, requires Mac OS X 10.5.8 or later. The original 1.0 release ran on 10.4.8 and later. Every version was a Universal binary for Intel and PowerPC.
Is Spanning Sync still available?
No. Sales ended and the sync service was shut down on June 19, 2013. This site remains online so that the documentation, release history and support notes stay available.
How do I uninstall it?
Run the uninstaller included with the download. It removes the preference pane, the menu-bar item and the background components while leaving your calendars and contacts untouched. Details are on the download page.
