Since Mac OS X 10.5 "Leopard" and Spanning Sync v1.1 shipped three weeks ago, we've learned a lot about some undocumented changes—and a few serious bugs—in Leopard Sync Services and iCal. We've moved quickly to adapt, releasing three updates in rapid succession, the latest of which is Spanning Sync v1.1.3. If you haven't upgraded, please do so now.
We've been able to address almost all of the issues Leopard users have reported, including high CPU and memory usage, "referenced but did not push" errors, and false Delete Protection warnings. The biggest remaining issue involves a bug in iCal that causes it to become "stuck" and not properly reflect changes made in Google Calendar.
Some users have reported that disabling the Address Book Birthday calendar fixes this problem, while others have had success resetting their sync history as described here.
Apple is aware of the iCal bug causing this problem (Apple bug #5597932) and we're optimistic we'll see a permanent fix soon. Until then please be advised that Leopard iCal may not reliably reflect synchronized calendar events.
