Have just noticed that birthdays in iCal on my Mac are duplicated. Deselecting 'Birthdays' (Subscription calendar) in iCal removes ALL occurences of birthdays. The #calendar shows no duplicate and all birthdays seem to be on display; however, selective birthdays are not appearing in Calendar on my iPhone 4S (but, otherwise, there are no duplicates!).


Anyone any ideas on what has gone wrong? The fault(s) are certainly recent, as I know all was in order on Friday last (24/2/2012).

Mac mini (Early 2009), Mac OS X (10.7.3), 2GHz 8GB

    Look in your address book (on your mac), do you have iCloud as well as On My Mac accounts? if you do that is where the dupes are coming from.

    During the transition to iCloud you were given a chance to delete or leave intact your On My Mac contacts, I guess you chose not to delete, hence 2 address books, it's a fairly common error.

    Perhaps I didn't make it clear enough in my earlier reply: when moving to iCloud, all the contacts in the 'On My Mac' account were deleted and - until a couple of days ago - I had no problems with duplicate (Birthday) entries in iCal. As that account cannot be deleted (I tried again this evening, to no avail), deleting all its contacts is all that can be done. So, there was no error on my part (in the first instance), but something put the contacts back in there!!

    OK, not your error, but it is very very common (read around this forum), you're not synchronizing via iTunes or any other method? (iCloud is not a sync system so exclude that)

    I have the same thing happening, and I definitely don't have any contacts On My Mac.  I only have contacts in iCloud.  If I delete the birthday for a contact, both birthdays in my iCal calendar disappear.  If I add a birthday for a contact, only one birthday appears in my iCal calendar.  But for all the contacts that were in my iCloud contact list when I recently switched laptops (and used the Migration Assistant to do so), I have two birthdays junking up my calendar.  I really don't want to go through and delete and re-add every single birthday in my contact list.  Argh.

    Oh wow, just fixed my problem.  Turned off the birthdays calendar through preferences (not by just unchecking it from the calendars I can see, which didn't help).  Then turned it back on through preferences.  Voila! Single birthdays instead of duplicate birthdays.

    Yes! Finally, a solution to my problem. Thank you

    I'm now seeing some...not all birthdays...duplicated. I don't recall seeing this until today. I'm still on 10.6.8 and don't see any iCloud sync options. Mine still has a MobileMe option.


    Turning off birthdays in preferences didn't solve it for me.
