I don’t know what to call it-on Monday morning when I arrived at work and saw an iCal alert window on my screen for an Iridium flare that’d happened Sunday night. For that one particular case, Apple’s decision on when to sync will fail you you won’t get an alarm that you were supposed to. Almost every time you want to know about a new entry, you’ll have the Calendar app open, and since that’s when the syncing happens, everything works out just fine.Įxcept when the new event has an alarm, and you don’t open Calendar sometime before the alarm is set to sound. Changes to your calendar are relatively infrequent, and turning on the antennas periodically to look for new entries that are almost never there doesn’t make a lot of sense.

This is because calendar events are synced only when the Calendar app is open. Does the alarm sound when the five minutes have passed? No. Now go to your iPhone 3 and check your Twitter feed, play a round of SpellTower-do anything but open the Calendar app. Make a new calendar entry on your Mac for five minutes from now and give it an alarm to sound at the time of the event (0 minutes before). The event you just added won’t be there at first, but soon you’ll see the little gear icon spinning at the top and a few seconds later the new event will appear. 2 Move to today’s date if you’re not already there. Now pull out your iPhone and open the Calendar app. Try this two-part experiment: First, make a calendar entry on your Mac 1 for later today.

I’m still not sure whether I made the choice to have iCloud sync manually (and have forgotten about it) or whether that was the default when I updated to iOS 5. Joe Saponare’s comment explains the problem well. The behavior described in this post was due to a couple of choices in the Settings for Mail, Contacts, and Calendars. ![]()
