Issue: Ipad iTunes Wi-Fi syncing to wrong PC

On my Ipad, General Tab - iTunes Wi-Fi Sync, my Ipad wants to sync with an old PC. How do I change this so it will sync with my new PC? I have authorized my new PC to sync with my Ipad. I see no options on the Ipad to change which PC it syncs with. I have signed out of my Apple ID on my Ipad, shut the Ipad completely down and back up. I've signed out of my Apple ID on my PC. I've disconnected my Ipad, reconnected to my PC and clicked sync; it goes through the synching to finish. My Ipad continues to show the old PC: Sync will resume when "......." is available. So now what?
Whether related or not, the last week my Ipad App Store Icon has shown 8 updates but when clicking on app, then updates it shows nothing. Could this be related?

I had this issue of not syncing over wi-fi & i have fixed this. Below were my devices,
1. Windows XP Laptop
2.ipad 2 with ios5.
Below are the steps to ensure wi-fi sync works.
1. Connect your iPhone/iPad with USB cable to Computer where itunes installed.
2. Click on the "device" icon in itunes, & in "Summary" Page, ensure you have enabled the option "Sync Over Wifi My Ipad / iphone"
3. Disconnect the Cable,
You should be still able to see your ipad in itunes, if not, follow the below steps
4. Enable Upnp in your computer.
5. This link, will tell you, how to enable upnp in windows machine. --> http://support.microsoft.com/kb/941206
6. Restart your Computer
7. Ensure SSDP service is running in Automatic mode.
8. You should also ensure upnp is supported in your ADSL or Wi-Fi router.
9. IN your router, under LAN settings (Advanced), there will be option of Upnp, enable this. Even if it is enabled, disable & enable it. Restart the router once.
9a. The Upnp & SSDP would take 10 minutes to discover the device. Have Patience at times .
Open iTunes & Power on your ipad, you should be able to see the ipad in itunes now. if not,
10. Close your itunes & power off ipad.
11. Restart the service called "Apple Mobile Device",
Open iTunes & Power on your ipad, you should be able to see the ipad in itunes now, if not.
12. Disable Firewall & IPS in your Network Connections. Disable built-in Firewall & IPS in Virus Softwares. Ensure TCP ports 123 and 3689, as well as UDP ports 123 and 5353 are allowed. Refer to this link for more inputs --> http://support.apple.com/kb/TS4062.
13. Close your itunes & power off ipad.
14. Restart the service called "Apple Mobile Device",
Open iTunes & Power on your ipad.
This should be working now for sure shot. . I bet.

ITunes not syncing App layout or folders to iPad (iTunes 10.1/iPad 4.2.1

I eagerly awaited 4.2.1 to finally put my apps into folders on my iPad. I have nearly 300 apps which are unorganized, many not accessible from the standard iPad screens since they go beyond the 11 app pages.
I spent a bunch of time making folders and organizing this mess using the brand new iTunes 10.1, iPad 4.2.1 and on my Apply / Sync, ALL of the time customizing was lost -- none of the folders appeared on the Ipad after the sync.
I tried even moving 1 app from another screen, and it didn't sync over.
I then made a couple folders on the iPad directly, and when reconnected to iTunes, I see these folders. Any subsequent alterations made on iTunes don't sync over.
I wonder if this is related to going over my 11th screen limit?
I dread dealing with all of these using only the iPad. I know it’s a lot of apps, but that's what folders are for!
Anyone else not getting iTunes to sync folders/app arrangements with iTunes 10.1 and iPad 4.2.1?

I have this issue as well. I have an iPhone 3G 16GB, just updated to the latest iTunes and 4.2.1 firmware. I'm on Windows 7 Professional 64-bit. I've spend like 1,5 hours total reorganizing apps, all for nothing.

Are you attempting to sync music from your iTunes Music Library on your PC?
What options do you have set on the Music Tab for your iPad in iTunes?
What happens when you sync?
Any error messages?

IPad Mini Retina not syncing with iTunes

My iPad Mini Retina has not been syncing with iTunes for some time.
I have reset it - by holding down the home and power key. I am using the new Macbook Air 2014 - because it has crashed on a few occasions it has also been restarted recently.
I am running IOS 7.1.2 on the Mini and 11.3 on the Mac Air. It has stopped at various parts but the last few times has been stopping at Step 4 of the sync. A few people seem to have had this issue but I have not found a resolution yet.

Serious Sync issues between iTunes 8.0.2 and AppleTV 2.3

Please Help,
Everything was just wonderful until several weeks back when the AppleTV started having sync issues that seem to have degraded into oblivion. Rebooted everything, checked all software loads, tried many of the suggestions (no blocking network / firewall issues) and have even tried adding redundant port allows for any and all ports I could find going in / out of Apple TV. But to no avail there seems to be a bug that got introduced somewhere with the sync mechanisms.
The Apple TV can purchase movies, download them fast to start playing, view youtube videos just fine and play all of the media great, So can my Mac and all media / iTunes functions work well it even syncs with my iPhone / iPods well.
However... The only way I can get the AppleTV to sync is to reboot it, then it will sync some, iTunes will just get to a forever syncing with Apple TV state (which you have to stop), reboot AppleTV again, it will sync some more, until it stops, iTunes is stuck syncing forever with AppleTV again, repeat and rinse about 4 more times and you have it all synced.
If there isn't anything to sync when AppleTV boots the Sync in iTunes just spins for ever. I actually left it for 4 days just to see if it was actually doing anything. Minimal Network IO and of course it never finished.
If I stop the Sync with Apple TV in iTunes and then try to reinitiate it from iTunes I get the 3986 port error (which is bogus) unless there is some hidden setting somewhere in the OS that I can't find. And if there was a problem then why would it start and run when I boot the Apple TV.
It just seems that all of a sudden things started going wrong with Sync with no real change other than 'software updates' .
The only thing I haven't tried is to do a factory reset on the AppleTV which from what I have read doesn't really solve anything.
So, please someone from Apple or someone with some detailed technical experience provide some guidance on whether there is a bug that got introduced, version issues between iTunes/AppleTV, or something else going that I haven't been able to figure out over the last 2 weeks.
The only other unique things that may be different is that I have my iTunes library on an external drive (not on the internal drive). Does this many any difference?
Thank You in advance to anyone that can help me get to the bottom of these issues. This started happening when I was totally sold on AppleTV and about to buy a second one.
mmilford

And it's good to know I'm not the only one with the problem too! I just cannot sync stuff from Mac to Apple TV without it locking up. It actually seems to lock the wifi also, meaning I have to quit iTunes, turn off the wifi and then turn it back on again. But as soon as I open iTunes, the same problem again...
I've tried everything I can think of, searched all help articles, but cannot sort out this somewhat annoying problem.

Itunes/Outlook Calendar Syncing Issue - UTF-8 Flavor

I have had the usual and much discussed issue of outlook calendar does not sync with iTunes. The recommendations have been to remove iTunes and re-install, even blow away all the configuration files as well, and it even worked for me once. But not this time.
I was running Windows XP, and all of a sudden the Outlook 2007 calendar just stopped syncing. I upgraded from XP to 8.1, and that was not fun, but inevitable, and still didn’t correct the problem. Now, if you never upgraded from XP to 8.1 – you can’t – at least it is not a direct flight. First, you have to upgrade from XP to 8.0, then from 8.0 to 8.1, and there is no upgrade in place from XP to 8.0. So what does an upgrade in place mean? Your applications and profiles are not carried over. Just your data (if you ask nicely) is carried over – but all applications have to be re-installed from scratch, and reactivated if there was license activation.
So, forget about re-install of iTunes, I changed OS, reinstalled iTunes and Office 2007 from scratch. And still had the syncing problem. So, I wasn’t getting off easy.
In searching, I found some debugging stuff which I tried, as follows to turn on logging:
So, I ran the following:
cd C:\Program Files\Common Files\Apple\Apple Application Support\
defaults write com.apple.Outlook.client.exe ShouldLog YES
defaults write -globalDomain SyncServicesLogEverything YES
defaults write -globalDomain SyncServicesLogPersonalInfo YES
And this turned on a lot of tracing. The tracing helped me understand what was going on under the covers, But I am not sure I was getting enough of the information that I needed to really zero in on the bad record.
Now, I will pause and provide some observation of my specific Sync.
An iTunes Sync on a Windows machine when using Microsoft Office and Internet Explorer is selected on the INFO tab of the page for the device.
Selections include Contacts, Calendars, Bookmarks and Notes.
One of the programs involved with Outlook Synchronization is: com.apple.Outlook.client.exe
The program is called when Outlook data needs to be accessed, and is used for contacts, calendar and notes when those items are paired between the iDevice and Outlook. Bookmarks are usually paired with the browser, for example IE.
During the sync operation, each of these are sync’d separately, that is why if you follow the sync actions, iTunes will reflecting what is being synced at the moment, for example “syncing contacts”.
When syncing the calendar, and iTunes is running a slow sync, it reads the Outlook calendar using the com.apple.Outlook.client.exe and does processing of the recursion and time zone information.
For example, for recurrence:
[5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] Setting recurrence data <04300430 0d200200 000000ae 06000c00 00000000 00000400 00002120 0000e703 00000000 00000000 00000000 0000a0e7 980cc016 d10c0630 00000830 00000000 0000a005 00000000 00000000 00000000>
[5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] 0 recurrence exceptions
[5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] Reading the Extended Exception Info (i.e. Unicode data)
[5484 @ Tue Jul 01 10:30:59 2014] [YSLog com.apple.Outlook.client.exe] Done making compatible recurrence
For example, for timezone:
[5484 @ Tue Jul 01 10:30:43 2014] [YSLog com.apple.Outlook.client.exe] Could not create a time zone from outlook name, tried using name (GMT-05:00) Eastern Time (US & Canada)
Then the calendar entries are pushed, for example:
ca965dbc4717d9488fafc9266f1f829304082700 =     {
        "all
day" = 1;
        calendar
=         (
            ca965dbc4717d9488fafc9266f1f829382800000
"com.apple.outlook.freebusy" = Free;
"com.apple.syncservices.RecordEntityName" = "com.apple.calendars.Event";
        "end date" = "2020-05-11 12:00:00 +0000";
        location = "United States";
        "start date" = "2020-05-10 12:00:00 +0000";
        summary = "Mother's Day";
So, my SYNC fails, and I crash and burn with:
[5484 @ Tue Jul 01 10:41:22 2014] [_ISDVLog com.apple.Outlook.client.exe] SyncServices assertion failure (nil != strUTF8) in [(null) (null)], SDLogging.m:641 could not obtain UTF-8 flavor of formatted string
[5484 @ Tue Jul 01 10:41:23 2014] [YSLog com.apple.Outlook.client.exe] objcMain caught an exception:
name
NSInternalInconsistencyException
reason     : [(null)
(null)]: could not obtain UTF-8 flavor of formatted string
user info : (null)
call stack : (
Now I’m back. So, during the extract and push of the outlook calendar entries, iTunes is building formatted strings. Now, Unicode is usually 16 bit (2 characters) Unicode, sometimes called double byte code. UTF-8 is single byte, so realize you can’t squeeze 16 bits into a 8 bit byte. However, you could if the Unicode string only contained characters that were valid for the UTF-8 character set. My interpretation of the error message above was that somewhere a formatted character string contained a “non-UTF-8” character and raised the assertion. Now, my issue with the excessive detailing from the logs was that – at least with the logging parameters I had turned on – I couldn’t figure out which calendar entry caused the exception to be thrown.
First instinct was that the last calendar entry in the trace was the culprit, so I deleted that calendar entry, ran again, the sync went up to the previous entry, and threw the exception. This gives me two theories: Either the sync was processing the next entry – which wasn’t printed in the trace yet – and failed, or the sync was going back to previous records – like reviewing the buffer. In either case, the trace wasn’t helping and it was all theories.
Now what? What has everyone been saying? Issues with recurrence. And in the trace, as you see above as an example, “0 recurrence exceptions”, “reading the extended exception info (i.e. Unicode data)”.
Now, I have no clue what that means. My initial guess was that recurrence exceptions (I had non-zeros on some) was an error. But further research I realized what it could mean was that these were situations where there were recurrence exceptions. What is a recurrence exception? Suppose I want to schedule a meeting on the 4th day of the month, for every month of the year. Well, except maybe July 4th, because it is a holiday and the office is closed. I would send the meeting invite, and then a cancellation for the July 4th. (I hear there is no simple way to do this). I now have an exception because I broke the recurrence chain. Other forms of exceptions is if I keep changing the location, or the body of the invite – e.g. every month I update the agenda, but only for one recurrence, not the entire series.
So, keep in mind, that if the issue is conversion to a UTF-8 character, and it is failing, then uninstall/reinstall of anything is not going to help if the real issue at hand is the data in Outlook and is not a coding or configuration issue. Now, sometimes it is an issue, but you need to see why the syncserver tasks are failing, and may fail due to other reasons including other data issues.
So, what did I do? Well IO have 15K calendar entries, which, was taking an hour or two to slow sync (I call it a slow dance) and I was,spending days (maybe a couple of weeks) trying to fix this – and frustration was on the high end.
I removed some of my older recurrences, and changed others from never expire to like 25 maximum occurrences. No idea which one worked, or even if it was a coincidence. However, the UTF-8 error went away, and then I moved to the next issue.
Now, before we get there, with outlook 2007 finding recurrences is not difficult. Go into the calendar, and select appointment or list view (Outlook 2013 list view works ok). You can then sort on the recurrence column and see which (if any) items gave a recurrence pattern. Now maybe someone can figure out specific BAD calendar items that are throwing the exception to give us a better idea of what to look for and then report it so we can do further research.
Now, once we can get the issue out of the way, stop iTunes from throwing an exception, we are not 100% done yet. By this time what is in Outlook and on the iDevice is out of sync. We need to get that message to popup asking us if we want to merge the data between the iDevice and Outlook. This can be important if you don’t want to lose data. My issue is that with iTunes 11.2.2 for some reason won’t do it, i.e. when I select “reset sync history” it doesn’t work. At that point I was forced to rename my iTunesprefs, the syncserver folder, and a few other folders. In this case, for Windows 7 and later, the folders in “Apple Computer” of both the local and roaming paths, and I had to cancel running tasks that had those folders open. One way or another, you want the iTunes message asking if you want to merge the folders.
What can you do to help?
Report success or failures using the information above
Report if you are getting the same UTF-8 message, or if you are seeing other exceptions
Report specific cases of calendar entries that you find that you have isolated to be throwing an exception
Report any other logging/tracing parameters that you may find. It looks like you can turn on “ShouldLog” using the defaults.exe command for other tasks that iTunes runs.
This syncing issue has been going on for years, under different iTunes versions, there has to be something going on and an easier way to troubleshoot this problem. I wish I had the time, but right now I fixed the problem I had and was able to resync my Outlook with my two iPads and iPhone.
The only issue I have left at the moment is the message “the ipad xxx cannot be synced. An unknown error occurred (-54). – despite this error message, I am syncing, but the message is distracting and annoying.

Yes - both have time zone support and are set to London/GMT
The most recent of these aberrations was not even crossing a DST change - just a simple recurring event (which I've manually changed to single events by copy/paste).
I just tried a new one which goes back 1 hr 27 Oct - when UK clocks go back. As it's a dummy apt I'll leave it and see if if goes back to the correct time on 27 Oct! In the meantime, I can't afford for my appts to get screwed up so will continue to do them manually!
Thanks for your input.

IPad (iOS7.0.3) sync to desktop iTunes won't work with wifi ... Only wired

My ITunes won't sync my ipad and closes down in the middle. I have Windows 7 Ultimate. How do I fix this problem?

My itunes won't sync my ipad and closes down in the middle of the attempted syn. I have windows 7 ultimate. Any ideas about what to do?

If the steps above do not resolve the issue, attempt to sync with iTunes while logged in as a new admin user. Follow these steps to create a new administrator user within Windows:
From the Start menu, choose Control Panel.
Open User Accounts.
Select Create a new account and follow the instructions to complete the account setup process.
Once the new account is created, choose Log Off from the Start menu.
Log in to the newly created user account.
If the error does occur in the new user account, the issue may be caused by content downloaded or created on the device, such as podcasts and voice memos. Removing content from the device may address the issue.
If the error does occur in the new user account, the issue may be caused by content downloaded or created on the device, such as podcasts and voice memos. Removing content from the device may address the issue.
If these steps do not work at all, I would suggest calling AppleCare at 1-800-275-2273 (assuming your iPad is stilll within support or has an AppleCare Protection Plan) and let them know you have already tried all troubleshooting steps per TS2830.

You need to place the device in recovery mode ...
f you can't remember the Passcode, you need to restore the device from the computer it was last synced with.

If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present

Why can't i access my Apps that I downloaded through iTunes. I believe I'm doing something wrong and not that the issue is iTunes itself

Occasionally ill try downloading an App through my Macbook Pro 13.5 & it directs me to iTunes to be downloaded. So, I go to iTunes and download the App I need. For instance, Amazon. I go into 'My Apps' in iTunes and try clicking on one of my DL Apps, but nothing happens. Why can't I access the Apps, which I downloaded through iTunes.?I believe I'm doing something wrong and not that the issue is iTunes itself. I have OS X Yosemite 10.10.1. I am due for an upgrade from that software and also an upgrade for iTunes as well, but that shouldn't be the problem. I've tried everything on my end to troubleshoot. I don't really have the time during the day to call in and troubleshoot, so thats why I'm asking the community. Please help with this problem if anyone can. Thank You!

Once you download an iOS app, you cannot run that app from the computer. That can only be run from an iOS device. You cannot download Mac Apps from the iTunes App Store, those are downloaded from the Mac App Store. Two different places. If you want a Mac app that will run on your Mac, you need to download that from the Mac App Store. iTunes App Store only has iOS apps that work on iOS devices, iPhone, iPad, or iPod.
