Additions and changes to my iPhone calendar are not synced with ICal on my Mac. Syncing the other direction (adding or changing appointments on my Mac) works, but nothing I change or add on my iPhone appears on my Mac (the same seems to be true of contacts and notes). I have the same problem with an iPod touch.

Has anyone else experienced (and fixed) a similar problem? As it ism the iPhone-Mac sync only works in one direction!

    Here is something to try to resolve this issue.

    Open isync in your applications folder.
    Open the isync preferences and reset sync history.
    Quit out of isync.
    Connect the iphone to itunes and try to sync

    Hope this helps

    If you create a new user account and try syncing just the calendar events, does it sync from the iphone to the computer.

    To test this open system preferences and go to accounts.
    Create a new account, call it test or something.
    Log into the new account.
    Open ical ant put in at least one event. If you do not put at least one event into ical, itunes does not know to merge the data and could erase the events on the iphone.
    Once the test event is in ical, open itunes and go through the initial setup.
    Then connect the iphone and sync just the calendar events.

    Hope this helps.

    I had been having the problem of entries in both the calendar and address book that were made on my Razr not being uploaded when synced.

    After getting my iPhone the problem still existed.

    There is another thread on this forum you can search for that has a procedure that fixes the problem. Unfortunately it requires deleting your calendar entries and starting iCaI fresh.

    What I did was make sure my iPhone was correct for calendar and address book entries. After I deleted everything from iCal I used the iPhone to rebuild my calendar entries. This reset now allows for 2way communication between my iMac and phone. It is working the way it is supposed to.

    I suggest you look for the thread that contains the procedure. Perhaps searching for "unregister" and "sync" will find it as part of the procedure is to unregister computers from .Mac. I wish I could provide more info but...

    I think I found the answer in the Leopard discussions, not the phone.

    I'm having the same infuriating problem: events entered into phone do not show up on desktop calendar. I have tried everything including restoring the phone, checking different combinations of mailboxes, etc., wasting half a workday in the process. I think this is a BUG that Apple needs to FIX.

    But I will try one more time; and in the meantime add an asterisk next to appointments made on my phone so I remember to re-enter them on the desktop calendar manually. Not very sexy.

    I have not had this problem; but I have read it many times on this forum. Seems to me it only happens in Leopard? (My laptop is tiger 10.4.11)

    The process described by Roy Levien seems to be the one process that really works (just my observation from reading the same issue several times).

    Here is a suggestion for all Leopard users who have encountered this problem. Report it to Apple at If enough Leopard users report the same issue with the same version of Leopard, Apple will (we can hope) notice it as a bug and issue a fix as a software update.

    Happy 'putin

    Just a warning to babykong: I used the "Roy Levien" solution several weeks ago, and it fixed the problem. Happily went about entering appointments, etc. in the iphone, trusting they would sync back to the MacPro. Everything worked fine until some point when they stopped syncing back again.

    I also find this amazingly infuriating. I know that I've lost some appointments when I would make a conflicting entry on the macbook. I've probably missed some appointments.

    So... until this bug is fixed, and please make it soon, Apple, I write the event in that Notes iphone program, AND to make sure, I email it to myself to remind me to enter it in the calendar. And if anyone has seen a PERMANENT solution in these discussions or elsewhere, I'd really appreciate hearing about it.

    I had the same problem, and then all my calendars stopped syncing either way. They picked a beautiful time to do it, too... right as I was leaving on a business/pleasure vacation where I was making on the fly appointments. grumble

    However, I fixed it tonight. Here is what I did.

    1. Back up (export) all your iCal calendars. (not just good practice, you'll need them later) Make sure iCal is closed.
    2. under ~/Library/Application Support/iCal delete everything.
    3. under ~/Library/Calendars delete everything
    4. Sync your phone.

    At this point you should have your phone overwriting everything in iCal. If your problem is ONLY syncing from phone to iCal you should be good to go, if you can't sync either way, you'll need to:

    5. Drag all your backed up calendars back to iCal. In theory they will sort themselves out, but you might have some duplicates between stuff you've created on your phone and in iCal.

    I don't know if this will keep the problem from occurring again, but at the very least, I was able to test out my ability to create events on either side, and it works.

    I kept hoping that the last iPhone update would solve this for me, alas!
