Ipad sync failure

I am getting an error message from itunes saying ipad failed to sync, apps could not be determined.  Have restarted laptop and ipad, with no success.  Also tried wifi and wired sync without success.  Any suggestions?

Take a look in here. There are a number of different things that worked for these users.

  • IPhone & iPad sync failure with usbmuxd issues

    I've lost all wired connectivity between iPad and iPhone to the paired desktop (never managed to get the wifi sync working) despite using previously working connection via hub and then direct USB cable connection. I have checked that the devices appear within device tree in System Information so it's not likely to be a hardware fault.
    iOS devices are running latest 5.0.1 software
    Desktop has 10.7.2 running latest iTunes 10.5.1
    All software updated
    (The same machine has some mixture of software - including Xcode 4.0, 4.1 - so there could be some tricky thing which has occurred at some point during an upgrade path.. - some pretty old drivers lurking.. and there have been a few silent machine crashes which don't yet have an explanation so I don't know if they are related - but there does seem to be a clear issue with recognition of the iDevices by iTunes - Perhaps there is a corrupted driver file?)
    What is noticeable and seems new is that when I connect an idevice it starts to spew into the logfile:

    Seems to me likely that it will be something to do with the daemon or some other machine configuration weirdness - some pointers as to what to do next would be good..
    At the moment, when I get back from helping someone else with their IT!, I
    am going to set Repair Disk Permissions going (could take a while)
    am going to try to find the daemon and compare it with either a TimeMachine version or from a different machine..
    any other thoughts? has this been seen anywhere else by someone?
    Cheers,

    Steve,
    Did you make any progress on this. I have the same situation.

  • Since upgrading to iOs 5.1.1 and iTunes 10.6.1.7 my phone gets a sync failure message whenever I since thru the cable. I have no problem syncing with my iPad

    Is your iPad recognized by iTunes when connected to your computer via USB?
    If so, does Sync with this iPad over Wi-Fi remain selected under the Summary tab for your iPad sync preferences with iTunes?

  • Bonjour iTunes Wireless Sync Failure

    Looking to see if anyone has experienced any iTunes Wireless Sync issues:  Network setup as follows:
    2504 Wireless Controller running 7.6.100.10 and three 1602 AP's set for LOCAL Mode running CAPWAP, and running a Guest WLAN and a User WLAN.
    We use a wide variety of Mac products (iPad, Mac Mini, AppleTV, iPhones, MacBooks), and are now experiencing iTunes Wireless sync failures.  I have mDNS enabled, mDNS is added to the WLAN's and the interfaces, multicast is tuned on, IGMP snooping enabled, multicast is enabled on the wired infrastructure....the weird thing is all the other Bonjour features are working.  We can push desktops to the AppleTV, Stream Music, Print, share files, etc  iTunes Wireless Sync is not working.  I've been watching the mDNS browser and using the Bonjour Browser on my MacBook and I notice a two odd things:
    1) I never see a a Layer 3 Multicast MGID Entry with the Apple Multicast Network (224.0.0.251) populate in the Multicats Window
    2) I have the service enabled for ITunesWirelessDeviceSharing (_apple-mobdev._tcp.local.) in my mDNS profile but I never see any device use that sting.  While watching the mDNS browser I do occasionally see the follwing: _apple-mobdev2._tcp.local. which is generated from the iPhone 5's.  I copied the string and created a new service and added it to my mDNS profile but still no joy.
    Any advice would be welcomed

  • Every iPad sync ends with - Attempting to copy to the disk Macintosh HD failed unknown error -4

    I started getting failures of this nature quite some time ago, though before that the iPad synced fine. I'm trying to sync to a latest model iMac.
    The iMac was set up from the backup of my old iMac which died. Not sure if that's the cause of this. I have tried the file verification process I read about on another post, but after running it to completion it made no difference to the error.
    This issue has continued through each upgrade since it started happening. Both iMac and iPad are on the latest OS.

    Hello, I don't find a lot of cures for that, but might see the last post here...

    Re: iTunes Error - attempting to copy to the disk "Macintosh HD" failed     Nov 21, 2010 9:08 AM    (in response to cosmocreek) 
    When itunes 9 was released, they also offered a different way to organise media.
    Instead of putting music in "iTunes Music" it gave the option of putting things in "iTunes Media/Music".
    see http://support.apple.com/kb/HT3847
    Try putting things in the itunes 9 organization. Do this by going to the file menu.
    Select Library > Orginize Library. If you can select "upgrade to itunes media arganization". Then click OK and let it reorganize your library. If you cannot select this (becuase it is grayed out) then itunes thinks it is already using that method. In this case, try renaming your "iTunes Music" folder to "iTunes Media" - apparently in some cases itunes did not make this change, which might be what is confusing your ipod sync. Be prepared to rename this folder back to what it was in case it causes problems . . .

  • How can I share iBooks authored by me using iBook Author on 2 different iPads synced to two different computors? Both iPads have different iTunes accounts.

    I am in the process of authoring an eBook using iBook Author.  The project is a work in progress and I want to share the draft with other collegues.  We each have our own iPads synced with other computers and we have different iTunes acounts.  I attempted to preview the book on the new iPad, but the iPad did not come up in the available device window.
    Am I missing something or is there a way around this?

    Reset your iPad and see if that helps.
    Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

  • Can't make ipad sync apps to new computer's iTunes

    I have a slightly strange problem. In Sept 2012, I got a MacBook to replace a Windows laptop. I transferred all my itunes music across and used 'transfer purchases' from my Ipod Touch to transfer all the apps to the itunes on the mac so I could keep all my apps. I then ticked the 'sync apps' box, and synced and everything works wonderfully, all my apps are still there etc and I can download them from the app store etc on the ipod.
    However, when I did this with my iPad 2, it never changed from syncing with the old laptop. Under iTunes wifi sync on the ipad, music,movies,podcasts, books and tones are synced with the new macbook, and for some reason apps, itunes U and movies are synced with my old laptop. I can't download any new apps or music on the ipad from the itunes app/appstore app either (the buttons just don't do anything). Nor can I seem to, no matter how hard I try, make the ipad sync apps with the new macbook. The apps themselves work just as they ever used to.
    I understand with itunes 11 the 'sync apps' button has gone, so I tried transferring purchases and then syncing, to no avail. All my apps show up in the corect position under the 'apps' tab, but they just won't sync.
    I have some access to the old laptop, but it is 200 miles away and I can't access it for several weeks at least. There's nothing in the apps themselves that is absolutely vital for me to keep (although obviously it'd be annoying to lose all the data stored in them, such as game saves).
    Can anyone help?
    Thanks,
    Pippa
    Edit: Strangely, I can now get it to delete apps, by deleting them from the apps tab on iTunes, it goes all the way through the sync, but finds an app to sync (generally just one), gets halfway through that then cancels the sync. However, it has deleted the app I selected for deletion from the ipad. I still can't downalod anything from the itunes app.

    Oddly, I've now (through repeatedly trying to sync the ipad) got the apps to now sync to my ipad according to thw wifi sync menu on the ipad. However, the sync still cancels halfways through. It attemps to sync between 1-20 songs that aren't on my ipad (cause it hasn't been syncing) and then gives up and "cancelling sync" appears.
    Each time the number of songs left to sync is fewer and fewer, but I can't deal with an ipad that can only sync 5 songs per sync cycle. There's no reason given as to why it cancelled the sync, and none of the apps sync.

  • Outlook to iPhone sync failure – Sync suddenly stopped working for calendar events but continued for contacts and notes.   Finally Fixed!!!  SUPPORT TEAM – PLEASE SEE THIS – Complete explanation of cause and correction steps.

    The issue:  Outlook to iPhone sync failure – Sync suddenly stopped working for calendar events but continued for contacts and notes.   Finally Fixed!!! 
    SUPPORT TEAM – PLEASE SEE THIS – Complete explanation of cause and correction steps.
    The cause:  It is now clear what caused this problem.  For years I had several “all-day” events in my Outlook calendar (birthdays, anniversaries, etc.).  In May 2012 I decided to make some of them one hour  events so I could add alerts to remind me of the event.  I did this by dragging them in Outlook to the time I wanted and expanding them to the time slot desired and then adding the alarm.
    The symptom:  Syncing stopped working for the calendar but continued working for contacts and notes.  I didn’t realize sync was failing until months later when I missed two very important phone calls, so when I noticed it the cause was not obvious. 
    The failed attempts:  I’m head of a software firm and my calendar sync is a crucial to my business life so I took this on with a vengeance.  From a quick look at events in Outlook and the iPhone I could see that the problem started in May 2012.  Events before May were in both Outlook and the iPhone but events after May were only one or the other.  Unfortunately I had changed several other things at the same time relating to other events so again the cause was not obvious.  MANY calls with AppleCare proved them incompetent so my internal IT guys assisted trying many things.  We tried a huge number of calendar changes and several versions of iTunes, iPhone OS and Office as well as both iPhone 4 and 5, all without success.
    The fix:  After 18 months of frustration, MANY  hundreds of $ expense and MANY hours of wasted time I saw a blog that had a calendar sync  problem and it indicated all day events were related.  I changed the display of the Outlook calendar to the list view, added columns so I could see “all day” event check marks as well as times of events,  sorted on the “all day” event column to move them to the top, and for all events that were “all day” events AND had a start and end time, I removed recurrence and then added the annual recurrence back…
    After I fixed all events that had BOTH “all day” set and had a start/end time, I tried another sync.  It synced for the first time in 18 months! 
    Problem occurred May 2012 – fixed Nov 2013

    Hi, to remove dummy '_ModGrp' entries, rather than crashing the 'Suppr' key on your keyboard, you can use this basic VBA macro (launched for instance from Excel).
    It will recursively remove all '_ModGrp...' folders
    Sub RemoveFolders_Click()
        Dim oOutlook As Outlook.Application
        Set oOutlook = New Outlook.Application
        Set objNameSpace = oOutlook.GetNamespace("MAPI")
        Call CleanFolders(objNameSpace.Folders)
    End Sub
    Sub CleanFolders(objFolders As Outlook.Folders)
        For i = objFolders.Count To 1 Step -1
            If Left(objFolders(i).Name, 7) = "_ModGrp" Then
                objFolders.Remove( i )
            Else
                If Not objFolders(i).Folders Is Nothing Then
                    Call CleanFolders(objFolders(i).Folders)
                End If
            End If
        Next i
    End Sub

  • IPad syncing issues

    Have two issues when syncing my iPad:
    1) iTunes thinks my iPhone and iPad are one and the same device, so when I sync my iPad, iTunes adds the new apps that I have on my iPhone.
    2) When I sync my iPad my iTunes U programs are erased. This happens whether or not I download them through the iPad or add them via iTunes. Other videos (movies, t.v. shows or podcasts) are not removed.
    By the way, I have the "Manually manage music and videos" checked for both my iPhone and iPad.

    Does the iPad sync with iTunes? With my iPhone – if I purchase a song or video on my phone – it syncs with iTunes and copies my iPhone purchases to iTunes under "Purchased on iPhone." However, on my iPad nothing that was purchased on the iPad syncs to iTunes. Why? is that normal?
    In addition, Apple needs to add the function to stream iTunes to the iPad like it does between Macs. I should be able to purchase a video on my Mac and stream it to my iPad and watch it.
    Edit: Just to clarify. I can't add any music, podcasts or videos from my iTunes library without erasing the movies that I purchased on my iPad. Since I can't sync them I assume they will be permanently lost.

  • IPad syncing problem - HELP!

    iPad sync problem - HELP!  I keep getting this message "...cannot be synced because there is not enough free space to hold all of the items in the iTunes library (additional ...space needed)"  and yet I seem to have plenty of space on the iPad.  This just started today.  I even tried deleting some things to make even more room, but it didn't help.  Any ideas??? 
    I was thinking of restoring, but I've never done it...  should I?

  • IPad syncing issue

    I am having issues with my iPad syncing.
    1. It's an iPad gen 2. OS is up to date, running properly and it connects to my computer and iTunes.
    2. I am on Windows 8 and my iTunes is up to date.
    I have a new computer and thought that I had sync'd it before but I may not have. I am not sure if it is a windows 8 issue or not. And if it is, how to resolve.
    When I connect and try to sync it recognizes the iPad and goes through the steps but when it comes to the actual syncing doesn't. It just stops. I have transfered purchased songs from the iPad to iTunes and these show in my library, but doesn't seem to want to sync the other way from iTunes to the iPad.
    Not sure what else to do? I have read most of the links others have provided but doesn't answer the issue I am having.
    Help?
    Thanks!

  • IPad syncing issues getting on my nerves... suggestions?

    When I first got my iPad 3G 64GB, I decided to sync as a new device and auto sync apps. Okay, but that put 22 pages of apps on my device and I was forced to spend at least a couple hours culling them down to just to fit the ones I want on the iPad... about 160.
    Spent a good portion of the day yesterday filling up my iPad with comics and movies, and suddenly it gave a sync error. ***. So I try syncing and it recognizes it as a new iPad again, and deletes all my movies and tv shows. double ***.
    Then I notice the syn apps tab is getting ready to put every single app back on my iPad once again, all 22 pages worth, so I hit the check box and stopped the sync apps function. It asks me if I want to delete all 160 apps, and of course I say no.
    So then it goes to back up. A couple hours later it finishes, and this morning when I go to sync again, the syn apps box is empty, so now my apps won't sync properly. triple ***.
    Is there anyway to fix this without putting everything back onto my iPad and deleting all the hours of work I spent on putting the comics there? How do I get the iPad to understand "yeah... well, I really DO want to sync apps, but don't add the unchecked apps in the list and put them on my device again... and don't delete the ones already there and replace with the whole setup all over again?"

    Okay, but that put 22 pages of apps on my device and I was forced to spend at least a couple hours culling them down to just to fit the ones I want on the iPad... about 160.
    Did you do this by deselecting the apps under the Apps tab for your iPad sync preferences with iTunes followed by a sync, which removes the deselected apps from your iPad, or did you remove the apps direct from your iPad?
    After Sync Apps is selected under the Apps tab for your iPad sync preferences, it must remain selected. If deselected followed by a sync, all apps will be removed from your iPhone.
    With Sync Apps selected, you can remove an app from your iPad by deselecting the app under the Apps tab for your iPad sync preferences followed by a sync. To re-install an app later, reselect the app under the Apps tab followed by a sync. After downloading a new app with iTunes on your computer, the app will be selected automatically under the Apps tab for your iPad sync preferences.

  • On my MacBookPro the program iTunes comes up and my iPad sync's up and I get the message that a PDF file is not found

    A lot of times I create PDF files for my electronic designs and present them to my customers. A files under "Book" has been deleted from my computer, but still shows up as a book listed.  When I use my iBook on my iPad, the book is not there which is great, but the book (or PDF file) is still listed. When sync occurs each time the iPad sync's up a dialogue box is created stating two songs are not there and the BOOK is not found. So I highlight the book with the check box next to it and how do I remove the contents of the library for "BOOKS"?
