iCal v4.0.4/OSX.6.8 sync problem with iPad 3

I've asked for help on the iPad forum twice now without a single response, so I am thinking that it might be an iCal/iTunes problem rather then iPad/Calendar one!


I'll repeat the basics here and post this link ( to my iPad thread post which explains in more detail.


Essentially, syncing between my iCal v4.0.4 (1395.7) under MacOSX.6.8 Build 10K549 and my Calendards under iOS 6.1.3 (10B329) on an iPad 3rd generation is erratic and unreliable.  I do not use iCloud and syncing is done via USB cable and iTunes v11.0.2 (26).


What makes it worse is that the symptoms change!


Currently, appointments created on the iPad do not sync across to iCal but appointments created in iCal do sync across to the iPad.


Previously, existing appointments shown in iCal but which are subsequently edited show in iCal as expected but on the iPad as both the old and new entry.  Also, when creating an appointment in iCal the edit panel opens in the default calendar which is then changed to the correct calendar and actual data - the default panel and edited data both appreaded on the iPad.


I have recently noticed that iCal periodically, yet rarely, presents a message when opening: Upgrading iCal Calendars and when this has completed, syncing returns to normal.  However, I have no idea what prompts that message nor how I could manually start an "upgrading" so that I can force a syncing correction.


Complicated?  Well, it is rather difficult to explain what I mean as the problem is so erratic and inconsistent.


I have tried the Apple suggestion here: and it made no difference whatsoever. 


In short, how can I get the iCal and Calendars to sync reliably and acurately?


My forehead is somewhat flattened after I have spent many hours beating my head against a brick wall over this - please help before the wall gets damaged beyond repair!

    Since your post mentioned "Upgrading iCal Calendars..." you may want to try removing the file from your Macintosh HD/Users/yourusername/Library/Preferences Folder. Quit iCal, and drag the .plist file to your desktop.


    Then go to your Macintosh HD/Users/yourusername/Library/Calendars Folder and remove any files with "Cache" as a part of the file name. Log out/in, or restart and check Calendars for functionality.

    Have you, or indeed anyone else, any ideas where to start looking for this "needle in a haystack" glitch/bug/undocumanted feature?

    One last suggestion that I can think of is to attempt Resetting the SyncServices folder. Make sure that you follow the backup recommendations, and use the Lion/Snow Leopard section instructions.
