How can I remove default alarm for events in iCal on devices ios?

Same problem here. When adding an event without alarm from my Mac, it get pushed to icloud without the alarm, but then pushes further onto the iphone and ipad, WITH alarm.

Single events always gets the alarm "on the day". All day events always gets "At 0900 on the day". But ONLY on the iPhone/iPad.

When adding an event directly into iCloud (via Safari) it shows up on the iPhone and iPad WITHOUT the alarm. So something is adding the alarm when the event is created on the Mac.

All alarms turned off on my Mac, in iCal, on iCloud, on the iPhone and on the iPad.

OS X 10.8 (new machine/new install/not from backup)/ iOS 5.1.1.

I have the same problem too. OS 10.8.0 (new MacbookPro retina) and iOS 5.1.1. I am sharing my calendars with Mac (iCal and Fantastical), iCloud, and iOS (Calendar and Week Calendar). I reported this bug to Apple. Hope 10.8.1 will fix it.

Yep, I have the same problem...

Same Problem here by using OS X Server... i think its a Bug of 10.8 or a feature for iOS 6? 😉

When i add an Event on Macbook and Edit on iPhone ... than comes on Macbook an very strange Event Alarm ....

My Workaround at this time is ... Set an Default Alarm... than all fine ... i hope Apple fix it ... because i don't notify for all my Events ....

Sorry for Bad English i hope you can unserstand me 😀

I get this too. If I create an event on Calendar on my Mac, it causes an alarm to be set on my iPhone Calendar - at midnight! It also happens if I just move an event forward from one day to another on the Mac Calendar.

I also have the same problem... Anyone who can help??

I've managed to work around this by either

a) only add events in the iCloud.com calendar

or, if you have to add an event in Mountain Lion's Calendar app:

1) go to icloud.com afterwards, edit the event, add an alert for whenever (doesn't really matter), click "OK" to save.

2) edit the event again, remove the alert you just saved.

If you just have one iOS device it might be easier to post-edit the event there.

Here's to hoping they fix the bug in the next Mountain Lion or iOS update.

Finally, this issue resolved after I upgraded Mac OS and iOS to 10.8.2 and iOS6.

Updating to iOS6 and OSX 10.8.2 solved my problem 🙂

Considering this topic as "solved".

Agreed, solved!

Give the issues with iOS6 eg Maps I'm staying with 5.1.1 for now. Is there any way to get this working on 5.1.1?

OK, so I have had this issue for the past several months. I think it all started when I upgraded to ML from SL and migrated my calendars and contacts to iCloud. That was a couple months ago. But now I am running 10.8.2, and about two weeks ago I upgraded my iOS devices to 6.0.1.

I don't seem to be having any issues with events that I create now, but all those old events that were migrated to iCloud a couple months ago, many of those sound alerts on the iOS devices even though there was no alert defined when the event was originally created. I have always had alerts off by default both in iCal and on the iOS devices.

So here's the question: is there a way to go through and disable all these spurious event alerts? I've been disabling them as the event reminders come up, but it's irritating. It would be nice if there was a way to turn them off all in one shot somehow.
