Z001 Level 1 Level 1 (0 points)

I have installed Mountain Lion on my Macbook Air couple of days ago and the calendar stopped syncing with my iphone. I sync through iTunes as I do not wish to use iCloud. Sync is set to all calendars and all events (no restriction), but nothing goes through. Tried adding events through my iPhone or through the Macbook, no difference, they do not get across to the other device. I have checked all settings, they seem to be carried forward from Lion unchanged. Any ideas or is it a Mountain Lion fault. Please do not tell me that the only way to sync will be through iCloud!


MacBook Air (13-inch Late 2010), OS X Mountain Lion, iPhone 4 with latest IOS

    Further to this I have tried some of the tricks from other forums. At some point the sync started to work, not sure the cause. Deleted cache files from the Library>Calendars and Library>Preferences (mail and external sync settings) as well as from Caches the whole iCal folder. Feel free to experiment, now it does sync both ways.

    Where do I find the right cache files to delete? I see many mnay files when i look- not ertain which ones are the safe ones to delete to get mine to synch.

    In the folder /users/Eugene/Library/Calendars, I deleted "Calendar Cache" and "Calendar Sync Changes", seems to work now

    Dear ZOO1 and eugenephoen, THANKS! that worked. For a minute they had me frightened I had to use "the Cloud" but your solution worked for me too. Delete the "Calander Cache" file and the folder "Calander Sync Changes" from ~/'your-user-name'/Library/Calendars folder solves the issue. Wonder if this trick solves the issue with all other reported problems with syncing (like reminders, notes etc.), I don't need them synced. Also wondered if this is a one-off or needs repair time and time again, but a quick test shows syncing works continuously now. Thanks mates, you made my day.

    Thank you for the well-meant advice

     

    Sorry - none of it works

     

    To say I am frustrated is a joke!!!!

     

    For starters my system does not follow the logic of Z001 - the file sequence is fifferent on my PB. The only cache file I could locate was 'Calendar Cache' and deleting it made no difference

     

    IAs a precaution I did first export my Calendar to the desktop; then I exited the Cloud; tried to do a manual sync between iPhone and PB. But watching the iTunes indicator bar reveals that the cal syn is simply not happening

     

    So there is a bug.

     

    Heck, my rave has always been how flawlessly the iPhone and MB speak to each other, Mountain Lion has wrecked that.

     

    At present the only workable solution is to dump Mountain Lion and go back to Lion.

    tried it and, for the first time, it raised some conflicts between my calendars (for appointments over a year ago, even though in iTunes I've clicked the button 'do not sync events over30 days old') - however nothing in the future appears to have synched.

     

    Any other ideas?

    thank you very much for the tip!  finally worked for me!!  realized the other day that everything that i entered on my iphone doesn't sync with my laptop.  was so frustrated with the problem.

     

    i love apple products but i hate it when apples forces us to move to something not everyone wants... like icloud...  notes syncing is only possible via icloud with mountain lion...  or is there a workaround?

    This worked for me as well, I'm glad to report. Thank you for the information.

    Deleting the files in Library did not help.

     

    Deleting the files in Library > Preferences

     

    com.apple.CalendarAgent.plist

    com.apple.iCal.helper.plist
    com.apple.iCal.plist
    com.apple.iCalExternalSync.plist
    com.apple.syncserver.plist
    ...did the job. Thanks!

    This just solved hours and hours of worthless attempts! Thank you so much. I was on the phone with apple support for 3 hours and they couldn't resolve it.

     

    Thank you is an understatement.

    It works for me. Thank you very much for the tip.

  • ankofskij Level 1 Level 1 (0 points)

    Hi there, you made my day! That was the answer I've been searching for two weeks!

  • Macbook Guy Level 1 Level 1 (0 points)

    Thank you for your post! Solved my problem as well.

    I wonder why this happens to som many people. Could be "dangerous" to lose important calendar entries.
