Calendar Sync Taking Forever (iCal)

I'm trying to sync my iCal calendars and its taking forever to sync. I left it running for several hours and it did not stop. I fear burning the green battery in on my new iPhone's screen so I've stopped the sync several times.
I tried it on my other computer (overwriting the old information) and it worked fine. On my powerbook I can't seem to get it to work.
Could it be a problem with iCal? Is there any reset options in iCal or iLife that might help me? It's only my calendars. Contact, Bookmarks and email sync with no problem.
Thanks in advance

I experienced this problem as well, and after looking at various potential fixes, I found that I had to delete certain .plist files to make the sync function work again. This is a problem that the casual user should not have to address, and something that Apple will probably address (at least I hope) shortly.
I'm up and running again, but I do note that my troubles didn't appear until I subscribed to some calendars off of the internet. I'm not going to do that again until this issue has been resovled. There are some other threads on this board that address the specific .plist files, so I'd go there first. If you don't understand what that post tells you to do, then I'd stay away from the fix.

    why is it taking forever to sync my ipad? its been syncing for about 45 mins I cant eject or anything is it ok to disconnect from computer??

    You're welcome.
    You won't lose everything.
    All iTunes content on your iPhone - all music, movies, tv shows, and 3rd party apps should be in your iTunes library on your computer.
    All photos and/or videos in your iPhone's Camera Roll should be imported by your computer as with any other digital camera. Did you read the info included with the link provided? If so, have you imported all photos and/or videos from your iPhone's Camera Roll followed by deleting the photos/videos from the Camera Roll after the import process is complete? If so, any change with your iPhone's backup time after doing so?
    Contacts, calendar events, and Safari bookmarks are designed to be synced with a supported application on your computer, so none of this data will be lost either.
    If your iPhone's Camera Roll is empty and no change with it empty, you can try deleting the existing backup followed by manually creating a new backup. Go to iTunes > Preferences and under the Devices tab select the current backup followed by selecting Delete.
    With your iPhone connected, right click on your iPhone under Devices in the iTunes source list and at the menu window that appears, select Back Up to create a new backup.

  • I just wiped out my ENTIRE Entourage calendar syncing it with iCal.  Help!

    Hey there. I'm using Entourage 2004 and I foolishly decided to try syncing it with iCal using the Syncing pane in the Preferences Menu pictured below.
    When I opened iCal to have it sync there was a dialogue with three choices and I chose the one that would have seemed to do the least damage. I can't remember now. The problem is, it wiped out my ENTIRE Entourage calendar. I didn't find this out until now when I brought the computer out of sleep. The last 4.5 years are gone. Absolutely nothing is there and the Office Notifications doesn't even start up.
    Is there anyway to retrieve this at all? Can I rebuild the database or something? Anything? The kicker is iCal isn't even showing my dates from Entourage even though it started a new colour/calendar for it.
    Please help!

    if your phone is still turned on. for example......they overcharge you by $300 one month and just reduce the credit you will have with them. now 2 months before your contract is up, your credit is gone (because they overcharged). you still think you have $300 credit with them.....until they shut your phone off for not paying the bill. probably won't happen, but i just thought i'd throw a scenario out there, as it is very common to have disputes on cell phone bills.

  • Why does my google calendar sync perfectly to iCal on my Macbook Pro but not my iPhone 4?

    The question as title is basically my problem.  Before I got my MacBook Pro I used my iPhone 4 (with iOS 5) to use the iCal app to edit my google calendar.  Events synced perfectly.  After getting my MacBook Pro things still seemed fine as well.  I was editing my calendar on iCal on my MacBook Pro, on Google's on-line Calendar App from other computers, and also on my iPhone 4 through the iCal App.  Suddently events were not syncing any longer.  I don't know what is the problem.  Things changed on iCal on the MacBook Pro still syncs to Google's online Calendar App and vise versa, but I can't do a thing with my iPhone 4 iCal. 
    Any suggestions?  I've tried deleting and resyncing my google account to my iPhone without any success.
    Thanks in advance.

    Hi Matt,
    I found my own solution to this problem and I think you can get it to work as well.  The thing is that you'll need to make your Google calendar your only calendar.  This means that you'll not want to have a Home or Work iCal because that stuff may not sync well with your Google calendar, but the Google Calendar data will appear within iCal on your iOS and Mac computer without any problems. 
    Before you do any thing I suggest, you must make sure that everything that you want on your calendar is on your on-line Google calendar.  If something is not there and you want it there, the thing you'll need to do is manually add it.  There is no work around that I have found for this.
    Next, on your computer:
    1. Go to System Preferences > iCloud
    2. Make sure that Calendars is not selected.  You don't want your computer or iOS devices to be confused with the iCal Home / Work, etc. calendars.  So let's not sync them.
    3.  Go to System Preferences > Mail, Contacts & Calendars
    4.  Delete Your Google account there
    5.  Go to System Preferences > Mail, Contacts & Calendars
    6.  Re-add your Google account
    Now you should be able to go into iCal on your computer and find that your Google calendar is there. 
    You will need to do a similar thing with your iOS device.
    1.  Settings > iCloud > Turn off 'Calendars'
    2.  Settings > Mail, Contacts, Calendars > Delete Gmail Account
    3.  Settings > Mail, Contacts, Calendars > Re-add Gmail Account
    This should make it so that you can use your Google calendar and it will be synced to your Mac computer, iOS device, and the Internet (Google's Calendar Website).
    You can see that this is in a sense a workaround in that you can't sync your iCal Home/Work calendars (or other calendars) created with iCloud to Google.  I'm thinking that's the problem I ran into before.  Anyway it works for me because I only need the one calendar and others are using Google that I need easy access to. 
    Let me know if you run into problems and remember you need to confirm that all your data is saved on the google calendar on-line (you can check through Google's website) before doing any of the steps above. 

  • Calendar syncing Iphone/Entourage/Ical/Lion OX 10.7.2

    Ok - so this is driving me a little crazy.
    I upgraded from Leopard 10.5 to Snow Leopard 10.6 and finally to Lion 10.7.2.
    Upgraded my iphone to IOS 5.0
    I use Entourage as my primary email and calendar.
    I clicked the synchronize contacts and also calendars in the preferences panel under sync services.
    What are the correct settings in;
    Iphone
    Entourage
    Ical
    Any where else
    For my Iphone, Ical and Entourage Calendars to always be in sync?
    I want to be able to make changes from my phone and from Entourage. I never change a thing in Ical, I just use it for syncing.
    Also, why can I not find the invitees option in my Iphone Calendar? Does it need to be switched on somewhere in the settings??
    PLEASE HELP!?

    Sorry that I did not mention that the problem with iCal is happening in my MacBook air, not in the iPhone.
    Regards.

  • With new phone, calendar sync takes forever

    Using iTunes 7.7.1 on Leopard I am trying to complete the initial sync with my brand-new iPhone 3G. It is currently stuck at synchronizing my calendars. I interrupted the initial sync process, updated the firmware to 2.0.1 and made sure that only one of my calendars is synchronized. It has been going on for well over 10 min now.
    In another forum someone had a similar problem synching with Outlooks calendar on Windows. The suggestion given there was to eliminate recurring appointments with no end date. Does this advice apply to the Mac's iCal, as well? I wouldn't even know where to begin with going through my calendar hunting down those items.
    Dominik Hoffmann

    Getting the same problem, in my experience the synchronisation does end eventually but it can take several hours. If you allow the process to end then it does seem better the next time although you can't always arrange to have your phone tied up for a few hours a day.
    Just for the record I've tried it using calendars without any recurring appointments and it is the same.
    I am using iCal with shared calendars iCal server in case that is an issue.
    Incidentally, I have also experienced appointments which do not appear to sync and one which seemed to disappear after a sync.
    Overall the advice is: use calendars with care!

  • 9900 syncing taking forever

    Having been served well by the 9780 for 2.5 years, I got a Q10 and immediately sent it back because of it not syncing with Outlook, So now I have a 9900 and I like the model but it is taking me 2.5 hours to synch calendar & contacts thru 7.0 software . I won't apologise for fact that I have a huge amount of calendar entries going back years because 9780 synced in 5-10 mins. I am desperate to know how to remedy this as I cannot keep updating device & outlook calendar if it will take this long. Can I go back to 6.0 software or another idea please?!

    Hey belinab,
    Welcome to the BlackBerry Support Community Forums.
    Thanks for the question.
    If you have thousands of contacts and calendar entries, then yes it will take longer to synchronize in BlackBerry Desktop Software 7.0.  However 6.0 can not be used with BlackBerry Bold 9900 smartphone.
    With regards to the BlackBerry Q10, currently there is only import to BlackBerry available and two way synchronization will be available at a later date.
    Let me know if you have any more questions.
    Cheers.

  • Manual Syncing taking forever.......

    My G3, purchased 8-28-08, was replaced last night because it had lots of issues, even after upgrading to 2.1 and updating my MacBook to 10.5.5. One of the major issues was around Mobile Me, not working. In the midst of addressing these issues, my manual syncing is now taking an excessive period of time to sync. I've been spending far tooooooo much time in the Apple Store, and on the phone with Apple Specialist. Does anyone have any idea why it's taking sooooooo long to do a manual sync? I've pretty much given up on Mobile Me. I had Palm TX, which I thought was from the stone ages, but at least it did a sync in record time. So far, G3 has been a nightmare. I just want to be able to at least manually sync it in a reasonable time. Thanks for listening.

    As mentioned, I will just confirm seeing a lot of blogs and comments in blogs about the USB port you use and it effects Mac users more so than Windows users.
    1. Make sure it is USB 2.0.
    2. Make sure it isn't a Hub.
    3. If it is a HUB, don't have any 1.1 devices on the same hub.

  • Syncing taking forever

    I plugged my IPhone into my Macbook Pro to sync about 2 hours ago and its still syncing. This happened yesterday as well so I had to cancel the sync so I could go out. What could be causing this? I did purchase about 40 songs from ITunes on my Macbook and add a couple things to my calendar but this is crazy.

    Hi Mo Morrill,
    i had the same thing some time ago when initially syncing my phone.
    It was because i clicked around in the Settings while the sync was starting up and i accidentally clicked away the window which asks to access my keychain for my eMail accounts.
    Rebooting the host machine solved the problem. Some iTunes sync service was get stuck.
    Please try to reboot your machine (i did also reboot the phone at the same time)
    Regards,

  • Sync taking forever and freezing

    Can anyone help? Normally my iPod touch syncs in seconds, but since yesterday it attempts to sync... then freezes and takes hours... I end up unplugging it. Some songs will be on my iPod touch, some won't.
    Any idea whats causing iTunes to be so terrible?

    Some folks have found that podcasts or voice memos were causing this. Delete them off the itouch itself, then plug it into your PC.

  • Lightroom mobile syncing taking forever

    Lightroom 2015 and Mobile for Android are set to sync automatically. I have 95 photos on my mobile, and 6 more have just been added. The 95 are showing on the desktop, and on the nameplate it is saying "syncing 96 photos" and only one of the new ones has shown up so far. It has been syncing for an hour. I have previously tried disabling and re-enabling syncing, disabling the virus/firewall scanner, exited LR and restarted, restarted the computer and each time it has been stuck in sync mode for ages. My broadband connection is 20Mb/s. How long should syncing be reasonably expected to take?

    Hi. Did you trigger a delete data via LR preferences ->Lightroom mobile.
    I'm not seeing a catalog connected to your account.
    Did you import originals via the connection-kit?
    Thanks

  • MS Entourage taking over iCal

    Hi Everyone,
    Can someone advise as to how I remove Entourage from my list of calendars in iCal under "ON MY MAC". I haven't used Entourage for over 3 years now and this calendar keeps taking over iCal. It is causing issues with my creating calendar events and inviting people to the event. I have tried deleting Entourage from my list of calendars and it keeps reappearing.
    Please help!
    Thanks!

    Welcome to Apple Discussions,
    1. Turn off Entourage syncing within Entourage.
    Make an iCal backup, File > Export > Archive.
    Reset sync history: http://docs.info.apple.com/article.html?path=iSync/3.1/en/9247.html
    Remove the following to the trash and restart your computer:
    Home > Library > Caches
    Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache)
    Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove them all.)
    __NOTE: Removing these files will remove any shared (CalDAV) calendars you may have access to. You will have to re-add those calendars to iCal > Preferences > Accounts.
    Once the computer is back up and running open iCal and test.
    Hope that helps.

  • Apple advice on importing Entourage calendar from iCal - taking forever!

    Hi everyone,
    got onto Apple support today asking about moving our entourage calendar to iCal. So, sounded simple enough. Opened iCal, chose import, selected entourage and away we go. 7 hours later (no, I'm not exaggerating) it has got about 3/4 of the way and now the progress bar hasn't moved more than about a millimeter in the past hour. What the heck do I do now? It's almost 2am here - just let it continue running until the morning? At this rate it might take the rest of the week to complete!
    Why would it take so long? Is this normal? Any faster way to achieve this? What about if I sync entourage and iCal, then when everything is there, export the entourage calendar from within iCal, then delete it, and then import it into the Home or Work calendar - would that work. This is so frustrating

    Same thing here. Drives me crazy. Been importing for days now, always have to force quit the app since it's stuck at around 75% of the import.
    Is there any way to get this to work?

  • ICal calendar sync runs ... forever?

    I've stripped down to sync'ing just one of several calendars, and the sync just runs and runs, on the order of hours.
    No matter how long I let this sit, there is never any data placed in the iPhone's calendar. Based on other posts here, the only thing I could find to try was switching time zone usage on on both sides, but that didn't change the situation.)
    Has anyone else seen this behavior?
    (MacBook Pro 1 GHz, Mac OS X 10.4.10, iCal 2.0.5 (1069))

    ... but I'll be damned, you're right.
    Okay, so there must have been something garbaged in there. I note that I had previously disabled calendar sync with the SE T637 the iPhone replaces... probably cause the calendar was just to painful to use with buttons/joystick and I decided I didn't care.
    So, iCal/iSync issue, not iPhone at all. Thanks!

  • Why does my ical on my ipod touch not sync with my ical on my desktop if I put in an event on the ipod calendar?

    Why does my ical on my ipod touch not sync with my ical on my desktop imac ical?
    It will if I put it in on my desktop though.
    Please help,
    Brie

    Probably because you did not tell the iPod to sync the calendar in iTunes.
