ICal /sync errors

I have recently ( last couple days) encountered sync errors when trying to sync iCal between a lampshade G4 iMac, a flat panel G5 iMac, and my G3 600MHz iBook. All are current re operating system. Interestingly, both bookmarks and address book seem OK, just iCal - i.e. my wife will input data into our 'home' calendar on the kitchen counter, and after syncing, the changes will NOT appear in the same calendar on the other computers. I have done all the fixes described in these posts - no joy. Never had a problem before, and I am now reliant on this stuff working, so please, Apple, if you are there, something you have done ( no new installs on my end other than your Software update stuff) has messed up iCal -please fix it.

Dear All.
Have just updated both computers with the latest version of 'Tiger'. 10.4.3.
"Seems" to have resolved the comms sync problems. Well - to the extent that .Mac & the computers were talking; even if it does say "You have 2525 amendments to your Calender "!! Indeed I now have duplicates in Bookmarks and on the .Mac web site but that I can live with. [ Address Bk seems OK ]. Suggest when U are given the choice of "merging" or selecting .Mac as you source, consider which is most correct.
To convince myself that it all now works, I entered "Test from Laptop / iMac " etc in Address Bk and iCal and checked to see if it showed up on both computers and .Mac. - Which it did thank goodness. Wonder if we will ever know what that "update to isync" was ? Would be nice to kept informed, having spent hours trying to resolve it. Apple ????

Ical sync error: iPhone disconnected

I've tried resetting history, restoring the iPhone, waited for a software update due today, and turned off time zone support on both iPhone and iCal.
What should I try next?

This process, which AppleCare gave me last night worked to solve my problem. However, I have one nugget to add to the fix, a faster process to try first.
EDITED FROM PREVIOUS POST:
Try these steps to narrow down the offending calendar and/or event.
1. create a new calendar in ical. Name it test, iphone or something.
2. uncheck all your calendars in ical, so you can only view the events in the new calendar
3. put a test event in the new calendar ( in the future). Call it Test 1.
4. connect up your iphone and set the iphone to sync only to that new calendar.
5. In the info tab that shows up when the iphone is connected, make sure to sync ical calendars is checked
6. Set it to sync only selected calendars.
7. in the window that shows all the calendars, only have the new calendar checked.
8. put a check mark in the box not to sync items older than... Set it to 1 day.
9. Now click apply in the bottom right side of itunes. (this will see if the iphone can sync to ical)
10. Once you have established that the iphone can sync, go back into the info tab and uncheck the new calendar created and check only one of your old calendars.
11. Click apply and try to sync the iphone to that particular calendar.
12. Keep un-checking a calendar that syncs and check a different calendar until you run across a calendar that does not sync. The one that gives you a disconnect error.
13. Now that you've narrowed it down to the offending calendar, you know that it has to do with an event from yesterday and forward. (ED.- in my experience, this DID NOT prove that the event was limited to the time you specify for the sync. But it does no harm to narrow the scope for iPhone.)
14. Go back to ical and put a check mark in the calendar that is giving the issue. So now you see the new calendar created and the offending calendar.
15. Now you need to figure out which event/events that are causing the problem.
*NEW STEP* 16. Fast fix (try this first, and if it doesn't work, you'll try the longer piecemeal process.)
Cut and paste All events to your new test calendar. The fastest way do this is to open the list of events by clicking on the list icon (3 lines) on the bottom left of ical.
17. Sort by title and if any events show up with a blank title, fix these or delete them.
18. Sort by type of item so you only select the events, and not any ToDo items.
19. Shift click at the top of the list, shift-click at the bottom of the list and everything should be highlighted. Then, with the cursor on one of the items highlighted, Control-click and a menu will open. Select Calendar, and then your test calendar. This moves everything into your new calendar.
17. Try to sync.
In my experience, ical fixed some items that were queer by moving them to a new calendar. My original calendar was imported from Outlook.
If this doesn't work, you'll need to try again by creating another test calendar and then moving over a few items at at time, syncing after each import, wading through your events until you find the culprit.
We return to our regular programming here:
16. Start moving events over a few at a time to the newly created calendar and sync the iphone only to the new calendar. You can move events 2 ways.
16A. if you have the tray to the side expanded so you can view the details of the event, you can change what calendar it is in.
16B. At the bottom of ical there is a button to the right that allows you to view all evens in a list view. You can right-click or control-click on the event and move to a different calendar.
16c. *CORRECTION TO ORIGINAL POST* Sync iPhone.
17. Keep following step 16 until you receive the the disconnect error.
18. When you get the disconnect error again, you know that the last batch of events has the offending, or one of the offending, event/events.
If you run through all of your calendars and do not receive the disconnected error, then the data that was disconnecting the iphone was older data. (ed. -In my experience, this proved false. the error was buried in old data, even though I had the setting at "1" day.)

Lion iCal Sync Error

I keep getting this error when I try to set up my MobileMe account with iCal. All other services are working perfectly but my calendar. Does anyone have an idea on how to fix this problem?

Hi,
unfortunately, for me this does not work. Even I choose CalDAV it adds it to me MobileMe account info and I can e.g. "push".
Synchronization starts (which I can monitor with LittleSnitch) but then after 1-2 minutes the synchronization stops and the network traffic from iCal is dead but the activity monitor of the calendar within iCal is still pretending to be "busy".
No synchs anymore. No added events are synchronized no events are downloaded form MobileMe.
Any help ?
Many thanks
Peter

ICal sync prompts password which doesn't work

Dear support team,
Whenever my computer iCal syncs to my MobileMe, and thus to my iPhone, I get a prompt for a password that reads "Enter the password for your user account on 'End User's Computer'." When I type in my user account password it says "Sorry, you entered an invalid password. Please try again." I then type my keychain password and get the same message. I type my MobileMe password and get the same message, again. I have no other passwords to try. When I check iCal on my computer and phone, I see that the sync on iCal worked, regardless. Other than being annoying, the password prompt interupts FCP layoffs. So I set sync to manual, but forget to sync before I run to a location shoot with the incorrect unsynced info on my iPhone. I endeavor to find a solution.
One of the articles on this site instructed me to use Keychain First Aid in Keychain Access. To verify keychain issues, it prompts for my user login password, which works. It then says that there was an error, which I then repair. I test the hopeful result by syncing to iCalendar, but get the same interrupting password prompt. Another article instructs to unlock the "login" and "System" keychains, in Keychain Access, to do something there. I had unlocked and snooped around both, before consulting the sites, but now my user login password no longer works to unlock the "login" keychain, and neither do my other two passwords. Oddly, my user login password works just fine opening the "System" keychain My safari keychain locks and unlocks just fine with it's password. I go back to First Aid and see that my user password works just fine, and see that there are no errors in the keychain system, but I'm now afraid to shut down my computer fearing that I won't be able to login ever again. I'm thinking about following another discussion instruction to reboot the entire computer with the original Leopard OS disk, but that feels like a last resort headache. I could pack up the entire computer and bringing it to the nearest Apple Store Genius Bar, but that will take half a day.
I just followed a support instruction to reset the login keychain I was unable to open, restarted and tried the iCal sync with the same result as before. I can't think of anything else.
Any suggestions?
Thanks for taking the time to read this.

Just fixed it by going to MobileMe Sync Preferences and unchecking the box for keychain sync. No more password prompts that say "Invalid." Now the iCal on both computer and iPhone sync without interruption of work flow. I had originally checked the box to sync keychains so that I wouldn't have to type in ID's and passwords to enter sites on my iPhone. Big glitch in the system. Why have the box to check if it creates problems? Hopefully they'll fix it once, or if, they become aware.
Thanks for letting me think aloud.
Peace

IPod Touch / iTunes sync error -50 on iMac, due to new upgrade for iPhoto

I have an iPod Touch, software version 3.0.
I have an iMac, on Mac OS X 10.5.8.
I am on iTunes version 8.2.1.
I am on iPhoto 09 version 8.1 (415).
Ever since Apple released it's latest iPhoto upgrade about 2 weeks ago, I have not been able to sync my iPod Touch with iTunes, and instead getting a 'sync error -50'.
Apple's phone tech support did not know what the problem was and recommended me to Restore my iPod, as well as re-install iTunes. This did not help.
After much aggravation, I found a discussion group addressing the fact that it might have to do with the latest version of iPhoto. So, in iTunes I unchecked the sync iPhoto option, and now the rest of the sync's worked (iCal, Address book, music, movies, etc).
Still, I am looking for a solution, as I do not find not syncing my photos a long term solution. Can I do this on my own, or does a solution have to come in the form of a fix from Apple?
I want my photos back on the iPod, and am very thankful for any tips/help (...hello, anyone from Apple reading this?).

I don't think any of the work-arounds are really valid or deal with the problem. My Mac Pro desktop computer is 2 years old, so the problem obviously has nothing to do with a computer being new. I also don't see how it can have anything to do with iPhoto. If I get this error and "QUIT" iTunes and reboot iTunes, the iPod syncs perfectly, even though no changes were made.
I actually bought a new iPod this week because I thought my old iPod was failing (due to these repeated errors). Imagine my horror when the brand new iPod had the same problem.
Hopefully someone can figure out what going on.

How can I stop syncing error message: "Microsoft Word has encountered a problem and needs to close"

On my Mac I am endlessly receiving this message: "Microsoft Word has encountered a problem and needs to close" it relates to the sync which between Calendars (iCal and Entourage) .
The error messages were coming up every 5 SECONDS and were impossible to deal with. They stated there was a 'Blame Module' which wasEntourageCore
I have been unable to find any idea how to resolve this.
Please can anyone describe what they have done to sort this?
I am using MS Office 2008.
Turning off the sync between the two calendars was not the answer, as the messages continued. So I have temporarily disabled the sync between iCal/Entourage and my iPad. This has prevented the error message, but obviously means I must enter diary dates manually on iPad which is the whole point of the sync!
I haven't found a way to sync between iCal and iPad - this would be a possible work-round. But I'd be so grateful to know how to resolve the sync error.

Yearly recurring meeting created on iPhone breakes iCal sync with exchange

I encounter a reproducable bug with Snow Leopard 10.6.1's iCal stopping sync with Exchange 2007 SP1 (Update Rollup 7), as soon a i create a yearly recurring meeting on iPhone 3GS connected to same Exchange Server via Active Sync.
After creating this meeting, syncing in iCal is broken, reporting following error:
iCal[31968]: GetCalendarItem operation failed
iCal[31968]: error = Error Domain=CalExchangeErrorDomain Code=-11 UserInfo=0x117a06cc0 "iCal kann keine Ereignisse im Kalender „Kalender“ aktualisieren."
iCal[31968]: Queue operation failed
iCal will never get synced anymore, until this one meeting is deleted via iPhone, OWA or Outlook. Please note: E-Mail and contacts still sync without problems.
Can anyone having a similiar setup confirm this to be problem!?
Where can i "report" this officially to apple?
Used versions:
Mac OSX 10.6.1
iCal 4.0 (1362)
iPhone 3GS 3.1.2
Exchange 2007 SP1 Update Rollup 7
So everything up to date, except for exchange 2007 missing some fixes...
To better reproduce this, here's the procedure:
On iPhone create a new meeting, make it "whole day", set recurring to "weekly" and voila, next time you sync iCal it stops with exclamation mark!
After testing, delete the meeting, but make sure to delete ALL instances, otherwise syncing won't work anymore:-(

Hello all there,
i was strubbeling with the same problem, but i found 'a' solution.
Let's hope that apple would fix this in the next version of iCal.
If iCal is saying that it cannot be synced, and you found an error like this "error = Error Domain=CalExchangeErrorDomain Code=-11 UserInfo=...." in your console, try this (read carefully).
*What i have done.*
1. Get an pc with MS Windoos en MS outlook in your exchange network (yes really, you need it)
2. Open MS outlook (i used 2007).
3. Export your calender to a .pst backup file
4. Then navigate to "View > Current View" and hit "all events".
5. Select all events then delete them all
6. Import your backup file to the calender.
7. From step 3 to 6, they are waste of time.
*So... what you need to do*
01. Open iCal and remove your exchange account.
02. Get an pc with MS Windoos en MS outlook in your exchange network (yes really, you need it)
03. Open MS outlook (i used 2007).
04. Then navigate to "View > Current View" and hit "returning events".
05. Note all of your returning events in notepad (also events from the past).
+You can also delete these events from the past+
06. Now delete all these "returning events".
07. Press the send and recieve all button in outlook.
08. Grab a cup of coffee
09. Start iCal and re-setup your exchange account.
If your exchange account is syncing with iCal then you can recreate the returning events. If it isn't syncing try to remove some other data, but be shure that you have created a backup file.
In my case the error was in one of the returning events, but i have figured that out to delete group of events en try'd to sync again.
Please note that my 3G iPhone was syncing very good, at time of this problem.
This are the console error messages:
11/6/09 06 Nov 15:16:26 iCal[291] Couldn't find an NSTimeZone to match the SerializableTimeZone
11/6/09 06 Nov 15:16:26 iCal[291] WARNING: Failed to find TimeZone Identifier for Windows MeetingTimeZone: Casablanca
11/6/09 06 Nov 15:16:26 iCal[291] error = Error Domain=CalExchangeErrorDomain Code=-11 UserInfo=0x11a287ee0 "iCal can’t refresh events in the calendar “Calendar”."
My setup:
MS SMB 2008 with Exchange 2007 (full updated till 2009/11/06 - today)
iPhone 3G 3.0
Mac OSX 10.6.1
iCal 4.0 (1362)
So.... i hope that you can fix your problem with my post.
I will subscripe to this post for a while, so if you need some help; Post it!
Have a nice weekend!

Sync Error in latest version of Desktop Manager for Mac

Using Version 1.0.2 (build 8) (version of 4/19/10) -- since updating to this version, always get message that "A Sync Error Has Occurred - please try sync again."
Seems to be a problem with Contacts because if I sync only Calendar to iCal it works fine, but since it doesn't tell me the nature of the error, I am having a hard time troubleshooting.
Using Mac OSX 10.5.8.
And I foolishly just tried "repace all contacts on this device" option, which I thought would overwrite Blackberry with Address Book from my Mac...but just wiped out the contacts on my phone.
Please Help!

So i just did the same and yes, the sync error goes away, but i think another problem is occuring.
I use Entourage for my contacts and have a Blackberry to sync it to. Since contacts will only sync with ADDRESS i need to first sync ENTOURAGE with ADDRESS then it moves on to my BB. Since doing this exercise (above), it seems that ENTOURAGE is not syncing to ADDRESS...does this make any sense?

Hi,
I have a similar or the same problem. When syncing contacts, a dialog pops up saying "a sync error occurred", and the log file reads:

What has Mountain Lion done to iCal sync?

I'm seeing lots of questions about iCal post-Mountain Lionon these forums, but far fewer answers on this one!
I have four calendars on my iPhone 4 that run my life. Pre-Mountain Lion upgrade on my iMac they all synched perfectly well via iCloud with my iPad and iMac.
Since upgrading to Mountain Lion, the iPhone and iPad still sync properly. However, when I went into iCal on the iMac two days back, for the first time since the Mountain Lion upgrade, I think, none of my calendars were there. The only calendar showing was one for birthdays, which I don't ever recall setting up. My iCloud account was missing from iCal's "Preferences". Adding it back in restored all of my calendars, and I thought I'd sorted this problem.
However, today, I opened iCal on the iMac again today, and my calendars were all missing again. Just that "Birthdays" calendar there.The iMac hasn't been powered down or re-started during the time since I reinstated the iCloud details to iCal.
So, today, I've added my iCloud account to iCal's preferences again, but I don't have much faith that this alone is the solution, given that I did that two days ago too.
Anyone else getting this? Seems a basic sync error, but I can't work out why iCal should be "forgetting" iCloud accounts that have been added?
Tom

My problem is similar.. updraded to ML from 10.6.8 and now the Birthdays from Contacts are ot showing up on the main calendar.. I have the "show Birthday Calendar" checkid in calendare preferences..

IPhone 1.1.3 does not fix my iCal sync problems

Still having my wonderful iCal sync problems.
Got the old "iTunes could not sync calendars to the iPhone "name" because an error occured while merging data".
Gettin' kinda old after at least a month.
I've tried every suggestion in this group besides generating a new Admin account.

... wait a sec... oh wait a sec....
I just may have fixed my problem. Deleted <user>/Library/Calendar (Leopard calendar) and <user>/Library/Application Support/iCal (Tiger calendar) and then deleted all data and settings on my iPhone and I can finally sync a darn calendar without iTunes complaining.
Was even able to re-import one of my calendars and have it show up in...wait for it... BOTH places. OMG - welcome to the 21st century!
Even got rid of duplicate birthday calendars my iPhone had been building up!
Joy to the world! Woot Woot.

ICal Sync through Proxy

I recently updated to the new version of MobileMe iCal. Now I cannot sync through a proxy server. If I take my computer off the proxy, iCal syncs fine. When I put it back on, it quits syncing.
All my other MobileMe data is syncing fine through the proxy, it's just iCal.
Is there a new setting somewhere that I need to know of to put proxy settings in for the new iCal? The error dialog box says that iCal couldn't connect after trying for 120 seconds and doesn't think it's connected to the internet.
Thoughts and help are greatly appreciated!

It sounds like there could be a calendar even in your Entourage calendar, that is causing a problem.
Maybe you can try this:
Before doing anything else, make a full backup of your BlackBerry. Then, go to iCal and make a backup of that as well (File -> Export -> iCal Archive).
Then, create a new calendar in iCal. Create one new appointment for that newly created calendar. Quit and relaunch BlackBerry Desktop Manager, and then configure the calendar settings to sync with only that new calendar.

Repeated ical sync failure with latest version of Desktop Manager

My wife downloaded the latest version of Blackberry Desktop Manager today. Prior to this version, syncing her iCal calendars with Desktop Manager had been working just fine. Now she gets the "Sync Error" message all the time. Looking
in the log shows the "Attempt to insert nil...." error that has been reported here previously. Also, it seems to not be only attempting to sync future events (which she had checked) - it popped up with 5 conflicts all of which were literally years in the past.
I tried the fix reported in one message (delete the /Users/username/Library/Applications Support/Blackberry Desktop Manager and reboot twice) but that didn't seem to work. Any suggestions? Should I use another syncing program with
the Blackberry and the Mac and just ditch Desktop Manager until they get it fixed?

So i just did the same and yes, the sync error goes away, but i think another problem is occuring.
I use Entourage for my contacts and have a Blackberry to sync it to. Since contacts will only sync with ADDRESS i need to first sync ENTOURAGE with ADDRESS then it moves on to my BB. Since doing this exercise (above), it seems that ENTOURAGE is not syncing to ADDRESS...does this make any sense?

ICal Sync creates strange duplicates with every sync

Hi guys,
I read quite a few threads here as well as googled for my problem, but none of the solutions helped. I don't know if it's just a sync error or more to it, but this is happening (it started probably after updating to iOS 6.1 - before that everything was fine):
Usually syncing between my Macbook Pro and my iPhone 4S was flawless. If I made changes in my iCal on my iPhone I could see the new events on my Macbook Pro iCal as well (after the sync obviously) and the same vice versa.
However, after the update (I suppose) to iOS 6.1 all the changes that I made to my iCal on my iPhone didn't sync anymore to my iCal on my Macbook Pro. If I added a new event on my Macbook Pro iCal it was synced to my iPhone 4S - so far so good. However, if I make a change to an already existing event in my iCal on my MBP and then sync with my iPhone again it doesn't apply the change on my iPhone, but creates a new event.
So, in most cases I change the time of the event, but instead of syncing the new time a new event is created. The same goes if I change the location or name. The time stays the same, but a new event is created with the changed name and suddenly I have to events at the same time.
Meanwhile my iPhone iCal is devastated with events all over the place so that there's no use possible.
I checked all my settings in iTunes as well as on my iPhone, but can't find any setting wrong.
Need your help, guys!
Thank you!

Is your calendar in the mac OK? if so export an archive, look where it goes, write that down.
Then Quit the calendar from the menu.
The iPhone: hold both the Power and Home buttons at the same time, keep holding, until you see the white apple logo and then let go. let it start completely.
1. Start iTunes on the mac, connect the iPhone, uncheck "sync automatically", check "calendar" in the "advanced" paragraph on the bottom of the "info" page, then sync. The iOS calendar should now be correct again. Check that.
If not correct post that here with the #1 as identifier.
2. If correct, make or change one calendar entry in the Mac in tomorrow's day. Then sync, is that change coming correct in the iOS calendar? If not post it here #2.
3. If it is correct, make a new entry for tomorrow in the iOS calendar. then sync. Is that correct?
If not post it here with #3.
