Calendar erroneously adds alerts to new events

Discussion in 'OS X Mountain Lion (10.8)' started by kronborg, Aug 2, 2012.

    All default alerts are turned off in settings. When I create a new event, all seems fine on the Mac (it says no alerts), but when the event syncs to my iPhone and iPad, on there it has an alert set for "on day of event". I'm using iCloud as the only calendar account on all devices.

    Are any of you having the same problem?

    Also, when editing a timed event (that e.g. runs from 12 to 13 on a day) into a full-day event, the event suddenly runs for two full days when synced to my iPhone/iPad. The day chosen and the next. Also says I'm free on the event (on the iPhone/iPad), even though it should say busy, as shown on the Mac.

    I'm not the only one seeing this, right? Could it be solved by editing a plist file or something? I found another user with the same problem, but that's it.

    YES I am getting this. I thought it was the "Week Calendar" app but it happens to the default iPhone calendar app, too.

    Every time I create a new event on my Mac, when I later view it on my iPhone I find it has been given an alert at midnight. Which means I have to go through each new event on my iPhone and clear out those alerts, since I don't want to be woken up at midnight.

    I can't believe we're the only two getting this. Intensely annoying!

    UPDATE: To make matters worse, after I've deleted the unwanted alarm, and then move the event on from one day to another, the alarm re-appears. This effectively stops me from using iCal !

    Thanks for your reply. I've sent a bug report to Apple, hoping they will fix this soon.

    Yep, every time I create or edit an event, this happens. Calendar is really only useful for viewing my calendars at this point.

    I meant "Calendar" when I said "iCal" - forgot the name change ... I'll also send a bug report

    On your iPhone (and iPad), go to Settings->Mail, Contacts, and Calendars, and scroll down to the bottom where it says "Default Alert Times". Are all of those set to None as well?

    I know you mentioned it in the original post, but it sounded like you only checked those settings on the Mac, and not the iOS side.

    Yes, they are all set to None. I even tried to set them to something else, and then back to None, for the settings to re-register or whatever, but didn't help. Thanks for posting, still :) Let's see if the .1 update makes the alerts go away.

    To clarify: No alerts are added when events are created/edited on the iPhone/iPad. Only Calendar on the Mac is at fault.

    Yes I tried the same things too but no joy. And with me too it's triggered by events created (or moved) on the Mac desktop Calendar app, not by events created on iOS (unless they're later moved ahead on the Mac Calendar).

    In Calendar preferences under the Alerts tab, make sure those options are set to "none".

    I had the same "problem" as you, and doing this stopped the alerts from being added.
  11. macrumors member

    :) Are you using iCloud calendars? I still don't know if this can be reproduced on any Mac w/ Mountain Lion. But I guess I would know by now, if that was the case.
  12. macrumors 603


    Same problem here. I seemed to have fixed it by disabling the default alert in OS X Calendar (as mentioned above).

    This problem seems to have cropped up since the upgrade to ML - I don't think it's iCloud. Just my gut level feeling, anyway. It's been hard replicate, so all the evidence I have is anecdotal.
  13. macrumors member


    The thing is, no alerts are added to events created for a Google calendar.

    I've set all those options to "none", under all types of calendar, so it's not "problem" in inverted commas, it's a problem, and a damned annoying one, too.

    Also, the alert/alarm that occurs is "on day of event, at 00:00" which isn't even an option in the drop-down menus in that setting.
  15. macrumors 6502

    I have time same issue, but it sets alerts at time of event. Every hour of the freaking day I have an alarm going off. I have checked my settings on my iphone, ipad, and macbook and none are set to set alerts. I'm pretty annoyed and this has made iCal, which I have been using for almost 4 years, unusable. Please tell me someone has found a fix.
  16. macrumors member

    I haven't found a fix. And OS X 10.8.1 didn't include one. The files that store the default alert settings for Calendar (~/Library/Calendars/*.caldav/ServerDefaultAlarms and/or LocalDefaultAlarms) look correct. I have found some additional users experiencing the bug:


    Let Apple know by submitting a bug report, if you haven't already.

    Also having the problem with alerts being set automatically for any appointment set in calendar on my MacBook. And then feeding alerts to all devices. Sounds like a clock factory when I forget to turn them off. Count me among those who will upgrade my devices to Microsoft going forward. I have more bugs in my apple devices then I ever did in pc land
  18. macrumors 6502a


    Have you checked the setting both on your iPhones and Macs? I don't have an iPad, but I assume it is there also.
  19. macrumors 6502

    Yes, I have checked the "settings".

    I also tried turning it off and then turning it back on again.
  20. macrumors member



    I am so tired of going through 30-50 calendar events every time I change anything in ML, it makes an alert in IOS.(I have hundreds of repeating events! :mad:
    This is driving me crazy, and I'm having trouble finding fixes on the apple support pages as well.
    Has anyone come up with a solution?

    Have any of you checked your settings on iCloud.com yet? Go to the Calendar app there, click the gear and choose Preferences, and scroll down. Look for this setting:


    That's the most likely culprit. I had the same issue with a Google Calendar at one point.

  22. macrumors member

    No! It has become amazingly annoying that I have to grab my iPhone or iPad whenever I'm sitting in from of the computer, and want to add or edit an event. The bug even affects Fantastical (since it depends on Calendar in some way, I think). I asked the developers about it, and they confirmed the bug, but didn't know of any workaround!

    Thanks for the input, but yes, I've double-checked that setting from day one.
  23. macrumors member


    I wish it were that easy! But that was the best idea I've tried yet. :)
  24. macrumors 6502


    That's one of the first settings I checked, and it doesn't make any difference. Also it's notable that my spurious alarm goes off "on the day of the event at 00:00" - which isn't even an option in those settings.

    It's maddening having to delete these alarms every evening, or alternatively, only create events on my iPhone.

    It's an Apple bug, unacknowledged, and damned annoying.
  25. macrumors 6502a


    Try enabling that option, but set it for a different time. See if it then sets that alert as well as the "00:00" alert for new items.
