Calendars don't sync across .mac

I have an iMac, Mac Laptop, & Palm Treo (linked via Missing Sync to iMac). After sync'ing Treo to iMac it created new Calendars. The new calendars don't sync to the laptop (via .mac) however, plus entries I make on the laptop never get sync'd back to the iMac. I'm frustrated and not sure what to try...

I am experiencing more or less the same problem and another one with address book. I have an iMac running Leopard and an iBook with Panther. The calenders will not sync period. I have been battling now for a a day trying to get an iCal sync but with no result. I would be grateful for any assistance.

  • Calendars no longer sync across devices after iOS/Mac OS X updates

    Ever since updating my MacBook Air to Yosemite and my iPhone 6 to iOS 8.0.2 (or maybe 8.1.1), my calendars no longer sync correctly across devices. Prior to the updates, any addition or change I made to the calendar on my iPhone would be added to the calendar on my Mac the next time I synced my phone. Now I have duplicate events on my phone, the calendar on my Mac no longer incorporates changes from the phone and I get a dialog box on the Mac 2-3 times an hour about calendar conflicts. No matter how many times I review the conflicts and choose which events/updates to save, the box keeps coming back. I've never had a persistent issue like this with any previous iOS or Mac OS updates and I can't figure out why it won't stop. Help, please!

    OK, that was easy enough. Here's what I took from the log when I synced a few minutes ago. I kept the log entry for one of the multiple calendar sync conflicts.

  • Failure to sync across .Mac

    I have a set of calendars that sync to two computers across .Mac. I made a change in one, and then received a notification of conflicts that need to be resolved on the other. I resolved the conflicts and then did a sync, but each time, I get the notification that there are still conflicts to resolve.
    Any ideas how I can get these calendar changes to propagate better?
    Thanks.

    The short, though not explicitly always accurate, answer answer is: it takes time for changes posted elsewhere through the push-pull nature of the synchronization framework to be distributed across your synchronization pool. How much time, depends largely on the composition of your pool, and how—and how often or at what intervals—you synchronize.
    When you see a phrase like "Refreshing contact groups and calendar information…" appear in iSync, that indicates that iSync is interacting with the truth database on your machine, in anticipation of posting additions, changes or deletions to the Address Book, iCal or a supported device. In terms of your 'local' machine where this database is maintained, the Address Book, iCal, Entourage, iGTD, Daylite or other applications, along with iSync, are also 'local' and often interchange data in a manner which is not obvious to users, whenever an application is active in the foreground or background. Other components, such as additional machines, .Mac via .Mac Sync, Plaxo or similar synchronized 'services,' mobile handsets and smartphones and other supported devices are essentially 'external' and changes made on them may take longer to be fully distributed.
    In the case of two machines, one must interact to push data to and pull data from .Mac using .Mac Sync, before it is available to be pulled from or pushed to the other machine. In addition, the data does not move directly from iCal to .Mac to iCal: it actually moves from iCal to the truth database on one machine to .Mac to the truth database on the other and to iCal on that other machine. It must complete the transition along that path before it is 'visible' in the second copy of iCal.

  • Calendar won't sync across devices and other issues

    Hello all,
    I am running latest versions of IOS 8 on IPAD Air2, iPhone5S and latest Yosemite on IMAC intel last year model.
    There are few issues here....
    In Mavericks when I edited an event in calendars it would show up almost immediately on my phone. No more. In Yosemite I would edit an event and it seems like a 50/50 chance it would RETAIN in the Yosemite calendar. And if it does, it does no sync across devices. This is a pain in my ***.
    Second issue is when I use the 'shutdown' feature top left corner of OS X, the unit would begin to shut down then the spinning logo would keep spinning and unit would never shut down. The energy saver would take effect. I come from work thinking it was shut down, press the power button on back and the unit 'wakes' and continues with spinning shutdown logo.
    Third issue, my iPhone randomly asks for the iCloud password, even though it is enable across all of my three devices.
    Other than these issues I love Yosemite and IOS 8, but these are really kicking me from behind.
    I appreciate any and all help!
    Thanks

    OK, are you sure the events you are adding are added to an icloud calendar, only iCloud calendars will sync. Tap the calendar button to make sure all your calendars are iCloud calendars. Are changes making it to iCloud.com

  • Apps don't sync across devices after I moved to iCloud.  I have 1 apple ID (from mobile me) and 1 that use for iTunes

    Apps on my various iPads  and iPhone used to sync automatically.  Whenever I used to buy an apps, it would just automatically appear in all my devices.  I'm not sure what does that, it could have been the MobileMe account, but it was working perfectly until after I moved to iCloud.  Now, apps don't sync anymore.  Calendars, mails and contacts do.  I use 1 apple ID for I cloud and 1 for iTunes because I moved mobile me account to iCloud.  Could someone please help?  This is bugging me and I searched all over the Internet but can't find answer.

    I have the exact same problem. Help!

  • IPhone calendar items not syncing with Mac calendar

    A few weeks ago I noticed that items added to my iPhone calendar stopped syncing with my Mac calendar.  Items added or deleted from my Mac calendar, however, do sync properly to my iPhone. 
    iPhone 4S iOS 7.0.6.  Mac OS 10.8.5 (whatever beast that is).  I sync via iTunes and USB cable.  I do not use iCloud and am not interested in doing so. 
    I looked through other discussion threads, and  they did not seem to address my problem.  Thank you in advance for any help you can give.

    The answer given by randers4 here solved my problem (turn out I have Mountain Lion):

  • Calendars don't sync

  • ICal events entered in iPhone don't sync with Mac

    I am suddenly having problems with iCal entries made on my iPhone. They do not seem to sync with my Mac's calendar or on Mobile Me Calendar. I have tried syncing and still nothing. I initially had problems when I switched to the Beta version several months ago, got that fixed but now I'm suddenly finding events I entered on my iPhone not appearing on my Mac's calendar and I'm getting duplicates again, too. Very frustrating. I went to the duplicate calendar fix instructions at Apple but that didn't seem to fix my problem; I can live with duplicates. I can't live with missing events.
    Any suggestions or references to a fix? Thanks/

    I don't know if you have what I've also had, but http://discussions.apple.com/message.jspa?messageID=12382141 might help. I have this problem too. It's quite annoying. I have to keep iCal open before it syncs.

  • Bb calendar is not syncing with MAC, i am to the point that I am going to switch to an Iphone

    When I put the software on MAC, I was asked the first time where to sync and I choose the Address book and Ical.
    I originally just synced the phone book.  About 2 weeks ago I attempted to sync calendars to ICAL and I was having trouble until it worked.  Now I went to sync everything again and it doesn't. 
    I uninstalled the software and installed it and it still doesn't work.  I am try to see if it works to sync to entourage but I don't know how to change the settings to sync to Entourage.  
    I am getting so frustrated that I am thinking about switching to an IPHONE.  I have had a blackberry for 9 years, and never had a problem, until I purchased a MAC, which I love. 
    Can you please help me.  In need to sync my blackberry to my Mac, so it can sync with my IPAD.
    Thanks

    right. well i had no idea that apple doesnt read its own forums. however, i stand by what i said, i belelive spreading the good word between fellow apple users is equally effective at the goal I am wishing to accomplish. im sure i look like an idiot to you, but i feel you're sadly mistaken :/

  • Calendar/diary apps usable across mac and windows

    Does anyone know of any apps/programmes that i  can download on an I pad that also will work simultaneously on a windows system so i can network them, that also has the ability to save to a cloud. I want to be able to customise appts, eg  10 15 , 1130 and copy across each week. If not all of this possible would be great to achieve some of it!
    thank you

    Exactly.  Pushes the changes between devices.  Make all the changes you want, then when you reconnect to the network, they will be updated.   Caution:  It wouldn't be good to make changes on multiple devices and then try to sync.  There could be conflicts. But I believe that it would work as you are describing.  Try it out with small changes first (using specific test calendars/contacts you create) to make sure you can see what it is doing.

  • TS3999 Calendars don't sync between Iphone and Ipad.

    When a calendar entry is added from my wife's phone to mine there is no entry, but it's on my mini-pad instead. Why is it on one device and not the other? I have chosen sync and all events in settings , but is still doesn't work for both devices, only the min-pad. I can add an event manually, but can't receive any notifications on the calendar if its sent to my Iphone. Please advise, thanks.

    It requires that you set up the same iCloud account on all your devices (Settings > iCloud) or at least that you share some of the calendars between you and your wife (in case that you are using two separate iCloud accounts which is by the way recommended).

  • Can non-purchased sync across mac ibook app and ios ibook app

    I looked up many discussions, blog posts etc, but seem get conflicting answers. I really want to know whether I can sync non-purchase (from ibook store) pdf from my mac (maverick) to ipad ibook apps. I tried many times, but failed to do so. I never try books. Does pdf must be sync through iTunes or by email?
    The icloud sync is really frustrating. Previously, it took me quite a lot efforts to sort out the sync between pages and numbers. Not because I didn't do the right settings, but problems just arrived after upgrade mavericks. And I had to uninstall and reinstall the apps several times to make them work. So I wonder it is the same problem with the ibook.
    Someone pls help!

    Yes, eBooks (either PDF or EPUB) not purchased from the iTunes Store can be synced to iOS devices but not via the cloud. You must do it via USB.
    1. Make sure the eBook is in the iBooks library.
    2. Connect the iOS device to your computer via USB.
    3. Open iTunes and select the device, then select Books.
    4. Make sure "sync books" is selected and choose either the "all books" or "selected books" radio buttons. If you select "selected books" you'll need to then also select the eBooks to sync.
    5. Click the Sync button.
