What is the problem with iCal sync? I run it every night via a USB connection between my iMac (Intel i5, OS X 10.6.8) and my iPhone (4S, 5.1.1), because I am constantly updating my schedule on both machines. I am starting to lose track of the number of times the calendars on the two devices look different after syncing. The main problem seems to be with recurring events, which are the bulk of what I update. I will erase one occurrence of an event on one device, but it will still appear on the other. Or I will change one occurrence of an event on one device, and all subsequent occurrences of the event disappear on the other. Some recurring events, after being tweaked, mysteriously show up twice on one device (but not the other).


What is the story here?? I have been a mac/iPhone/iCal user for 3+ years, and I think all this stuff was fine until the last year or so. It might be time for me to switch to a different calendar system.

iMac (27-inch Mid 2010), Mac OS X (10.6.8)

    Maybe try the instructions posted here :



    It's in the seventh post down submitted by rorygilmore.


    I've just fixed my iPad/iCal/iMac sync problems using his instructions.


    Worth a go!

    As far as I understand the sequence, there's no way to avoid overwriting your iPhone calendars, but I'm sure someone will put me right if I'm wrong.


    Synchronising means causing something to occur or operate in unison.  Therefore the whole point of "sync" is for your calendars to share their data so that they hold the same information.  If you want your phone calendars to differ from those on your desktop then perhaps "sync" isn't what you need!

    Sorry I misunderstood you. 


    So, on the basis that you do want your calendars to sync...


    First off, I think in order to fix the sync problems you've been having, you'll have to carry out the complete replacement of calendar information on your iPhone with data from your desktop. 


    For any unsynced entries in your phone, I'd suggest you note them down then enter them into your desktop calendars before overwriting. Alternatively, you could do your overwrite then re-enter them into your phone afterwards.  Hopefully on your next sync they'll appear in your desktop calendars.


    I don't know how many entries you have (hope not too many) but I can't see any other way around it.

    Sorry to hear it didn't work. I hope someone with more knowledge comes up with a solution for you.


    Best of luck.
