Computer not authorised for syncing with iPhone with IOS 7

Unable to sync iPhone 4S (with IOS 7) to my PC. Error message is that computer not authorised. Have tried all on-line steps to rectify. e.g. Control Panel User settings.
Anybody have any clues on this problem?

Hi oxman78,
That definitely sounds frustrating! Let's give this a go to see if we can isolate the issue futher:
First, connect your device and choose the "Music" tab. Next, uncheck the "Sync Music" checkbox, and apply the changes (so there is ultimately no music syncing to your iPhone).
Once you have done that, recheck the "Sync Music" checkbox, and apply the changes once more. This will instruct iTunes to completely remove all music from your iPhone, and then copy the files once more. If you have a large amount of music, this initial sync may take a while.

My mac says it is not authorised to sync with my account but it is.

I have deauthorised and started again, but still have the same problem I have also follwed advice about the SC folder in users/shared but I dont have it. I am running Lion. Grateful for any help,
thanks

To be clearer. I get a message saying that the machine is not authorised (although I know it is) then I choose authorise and type in the correct apple ID etc and then get a message saying that the computer is already authorised. When I click OK on that I start all over again!

Windows (Vista) Calendar not supported for sync to iPhone?

I am using Windows Vista Ultimate x64 and I have an iPhone 3g S 32GB and in iTunes with my iPhone selected and I am under the Info tab it will show and allow syncing contacts to Windows Contacts but the calendar section says no supported calendar can be found.
Why will it sync to windows contacts but not windows calendar? Pretty stupid if you ask me. I do not plan to go out and spend $150 on Outlook 2007 or $100 a year for MobileMe just for this feature. This is just absolutely stupid that iTunes won't recognize Windows Calendar but it will recognize Windows Contacts, Windows Mail, and even syncing bookmarks from Internet Explorer.
If it is supposed to recognize the calendar, maybe Apple broke something in iTunes 8.2? I tried an uninstall of iTunes and Apple Mobile Device Support that was suggested at http://support.apple.com/kb/HT1692 I followed all the information there it still doesn't let me sync with Windows Calendar.

Unfortunately, you are out of luck. MobileMe can only sync calendars to Outlook. Maybe a future update will allow syncing to Windows Calendar but for now, there is no direct method of syncing.

With iTunes 11, it is not possible to sync my iPhone, and my iPod with my computer

Whith the new iTunes 11, it is not possible to sync my iPhone and my iPod with my computer.
1. the iPhone AND iPod are not detected by iTunes, they don't appear any more on iTunes. (for eg with iTunes 10, we see clearly that an iPod/iPhone is connected)
2. There is no possibility (page, button, etc) to sync and to see what is on the iPhone/iPod
Why?
How can i sync my iPhone and my iPod with iTunes 11?
How can i manage what is to sync between iTunes 11 and the iPhone/iPod?

Im using a PC, and yes i tried everything, turning my phone off, my pc off, plugging the phone on another computer, but nothing works

How to Use Multiple iDevices with One Computer

Iphone 4 does not want to sync with my computer

I Phone 4 s does not want to sync with my computer after I have installed new updated software on the phone. Just show's on phone that I need to connect cable to I tunes ? I have restarted my computer and installed updated I tunes. My security on computer has also been disabbled.

If you're running Windows, try closing iTunes, then right-click on the iTunes icon and choose Run as Administrator. Then try synching again.

ITunes crashed during transfer purchases now says This computer has previously been synced with an iPhone or another iOS device

The problem that have started when I was going to sync my iPhone 4 with current iTunes running on 64bit Windows 7.
I started iTunes and plugged in my iPhone.
All looked good and the iPhone came up as the device as it should have.
Next I wanted to transfer purchases prior to syncing so I started the Transfer Purchases process.
iTunes stopped working during the Transfer Purchases process
Now when I plug in my iPhone iTunes takes me to the “setup your iPhone” screen and displays “This computer has previously been synced with an iPhone or another iOS device” and only allows me to restore and old backup or setup as new.
Obviously some files were not closed properly when iTunes crashed during the transfer purchases process, how can I cleanup iTunes so that it will allow me to backup and sync my phone.
I am a software developer and am sure that a fix is not in the menu options What I am saying is that I can easily remove or edit corrupt files to get it working.
Thanks, Mike

The error message you're seeing is likely the other way around -- i.e. something like "This iPhone has previously been synced with a different computer". There's no problem syncing multiple iOS devices to the same computer.
However, the reverse is not true for the iPhone -- you cannot connect an iPhone to another computer without it being erased, even if you manually manage music and video. So, it sounds like you've been syncing your iPhone to a different computer?
Also, 5.1 (not 5.0.1) is the latest iOS.

This computer has previously been synced with an iPhone or other iOS.

I have just upgraded my iPhone 4 with the recent upgrade to 5.0.1 - I get the response "This computer has previously been synced with an iPhone or other iOS". I then get two options: 1) Set up as new iPhone, or 2) Restore from Back Up. So I restore the device - but it returns to the page that says "SET UP iPHONE, and gives me the 2 options again - set up new phone or restore. It will not sync my purchased apps onto the iPhone - my iPhone only shows bookmarkes saved.
When plugged into iTunes, it shows on the far left as my device plugged in, yet if I go to "FILE" - in the drop down menu, it shows "sync iPod" or "transfer purchases for iPod" but not iPhone... and its shaded grey. iTunes is up to date, and the phone is not jail broken. iTunes still has all my apps stored there - but they will not sync to my phone.
I have also rebooted my iPhone by holding the HOME and POWER button down, then releasing the power button. Nothing seems to work.
Any help would be greatly appreciated!

Try setting it up as a new phone. There is probably something wrong with the existing backup.

HT4972 The computer that I normally sync my iphone with has crashed and all info was lost.... Im trying to sync to my new laptop... how do I do this without losing iphone purchases, apps etc???? Help??

The computer that I normally sync my iphone with has crashed and all info lost.... I'm trying to sync and update with my new laptop but I am getting an error meassage that if I continue all purchases, apps etc will be deleted..... How to I do this without losing all my stuff??? Help I have no clue about technology!!!!!

The official way to do it is to restore the iTunes library that was on your old computer to your new computer using the backup of your whole system you regularly update. Then you are syncing the phone with the same old library.
Some of the information below is summarized by turingtest2 in the post at https://discussions.apple.com/message/18842615
Your i-device was not designed for unique storage of your media. It is not a backup device and media transfer was designed for you maintaining a master copy of your media on a computer which is itself properly backed up against loss. Syncing is one way, computer to device, updating the device content to the content on the computer, not updating or restoring content on a computer. The exception is iTunes Store purchased content.
iTunes Store: Transferring purchases from your iOS device or iPod to a computer - http://support.apple.com/kb/HT1848 - only media purchased from iTunes Store
For transferring other items from an i-device to a computer you will have to use third party commercial software. Examples (check the web for others; this is not an exhaustive listing, nor do I have any idea if they are any good):

I have the same problem. It is only with tv shows and only with programs I have downloaded after the software update.
Apple support sent me the above link too....but it doesn't solve the problem...my computer is authorized and the content is in my library and will play on my Mac air, but it will not sync the tv shows, it keeps saying my computer isn't authorized for it.
No answers here, but you are definitely not alone with this issue.

Hello hbell,
is there any reason that you do not want
to upgrade to v10.5.? Suggest you call
1-800-275-2273 Apple Support. Automated call
yet if you call back you can get in touch with an
Apple Software Specialist. They may be able to ship
you Leopard so that you can synch your new iPhone
to you own computer. Have the serial numbers of your
Mac and iPhone written down and ready for them.
As far as transferring data to your husbands MacBook
so that you can sync your iPhone on it I am really not
sure. Seems like a lot of trouble to get your data onto
your iPhone.
Good Luck,
A

Iphone 3g not able to Sync with Itunes

Hello,
I have iphone 3g with OS 2.2.1 and itunes 8.1
I m not able to sync with i tunes.
Whenever i connect phone, Itunes get hung .
Sometimes it displays foll message:
Itunes was unbale to connect iphone because it recieved an invalid response.
If i restart and connect it gives
Unable to Load Dataclas information for the iphone.Try reconnecting.
I did every thing
De-install,Re-install each and every thing based on suggestions at various places,still no use.
Even tried Syncing with Other OS XP , same problem-> Itunes gets hanged.
Im absolutely clueless about whats happened.
Somehow i was able to update the OS to 2.2.1 .
Dont know where the problem is....
Can any problem with Hardware lead to Such error..If yes..What are the probable hardware reasone...
Software wise i dont think anything is left unchecked,still any suggestions, help welcome..
Im really in need to sort this out as cant sync anything..the phone is blank wiht complete HDD free....No use.....
Please Please Please Help..!!!!!!!!!

As I read you updated your iPhone to 2.2.1. That means that maybe this cause the problem.
Sometimes when I connect my iPhone to iTunes I saw the message what says that "iTunes was unable to connect to the iPhone... " but if I reconnect my iPhone then iTunes recognize my phone and everything is OK.
If the reconnecting does not help you then I advise that reset your iPhone with 'Erase All Data and Settings'. Settings > General > Reset > Erase All Data and Settings.
If you reset your iPhone with 'Erase All Data and Settings' then your iPhone will delete your files and also the 2.2.1 software update and after that it will run with the original software what you bought with it.
The reset takes approximately 2 hours. And this is delete everything from your iPhone.
So, as it seems you can't back up your iPhone, that means everything what is on your iPhone will be deleted except if you don't have them on your computer.
After you reseted your iPhone, try to connect with iTunes. If it won't works then try it on an another Mac or PC and if you can't sync your iPhone at all, you have to take your iPhone to your carrier for a service.
Important note: After you reseted your iPhone, it will please that connect to iTunes to activate the phone. If you can't connect to iTunes your phone, you won't be able to use it!
As you know, without activating you can't use the iPhone.
If you can do the activation then you probably will be able to sync it.
If you can't be without mobile phone and just the iPhone what you've then don't do that until you maybe could miss your phone (I mean if you iPhone have to be serviced).

TS3992 what does it mean that my iphone will no longer back up to my computer automatically when i sync with itunes?

What does it mean that "my iphone will no longer back up to my computer automatically when I sync with itunes", if I turn my icloud backup to "on"? This doesnt sound like something that will make things smoother? I just recently lost all my calendar events and I am hoping to recover them.

Welcome to the Apple Community.
You can either back up to iTunes or to iCloud, you you choose to back up to iCloud, back up to iTunes will be turned off. Personally, I'd always back up to iTunes unless there is a good reason not to you.

ITunes doesn't show some playlists for sync with iPhone ...

I've got a few smart playlists.
The annoying thing now is that some of them do not show up under "my iphone" / Music / Playlists.
So I can't sync them to my iPhone ;-(
I used to have this smart playlist in the iPhone section of iTunes - but I can't remember when it disappeared.
For instance, I've got a smart playlist that contains some of the latest episodes of some podcasts.
It is populated fine, but it does not show up in the playlists for sync with my iPhone.
Another smart playlist (which I call "random pop") contains some music from my music collection.
This one does show up in the iPhone section of iTunes ...
BTW, just in case you wonder why I have this smart playlist containing some episodes of the podcasts: first, there are some episodes that I don't care for on my iPhone; second, with this little trick I can jump by a simple double-click to the next episode, no matter which podcast it belongs to, while listening to my iPhone.
Any insights, tips, and suggestions will be highly appreciated!
Best regards,
Gabriel.

Mystery solved: the playlist is now under "my Iphone" / Podcasts / Include Episodes from Playlist ...

I just Synced My iPhone 6 which had close to 2000 photos to a new computer (windows PC) and synced with iTunes.Now all my previous photos have been deleted which were there on my phone. Please suggest a way to recover those Photos . Thanks

I just Synced My iPhone 6 which had close to 2000 photos to a new computer (windows PC) and synced with iTunes.Now all my previous photos have been deleted which were there on my phone. Please suggest a way to recover those Photos . Thanks
P.S -I have not taken any backup of those photos. So please suggest any software or any other method.

If those photos were part of the camera roll, they were part of the backup as well and you can restore from the latest backup you made on the old computer. After that transfer the photos to the new PC, follow this article: iOS: Importing personal photos and videos from iOS devices to your computer
Then sync again to the new one, which will erase the phone again.
You can also try to copy the backup folder from the old computer to the new one and see if the old backups get recognized, check this article to find the location on your PC:
Create and delete iPhone, iPad, and iPod touch backups in iTunes
If the photos were not taken with the phone, your data is gone, photos you sync from iTunes to the phone are not included in the backup.
