  • My ipod touch does not want to sync with itunes

    My ipod touch ( 4 th IOS 5 firmware 5.0.1  8gb ) does not want to sync with itunes on my computer while on another computer be synchronized
    HELP please !

    What?
    What do yo mean it does not want to sync?
    Are you trying to say it does sync with one computer but not with another????? If so, this is by design. All iDevices are designed to sync with one and only one computer.

  • Q10 Calendar does not want to sync with computer (post operating software update)

    I have had my Q10 for close to a year and my calendar has always synced properly. In the last days it no longer wants to sync with a message "Sync was unsuccessful - Failed to commit changes to device". I recently upgraded the operating system to the latest version and I'm wondering if this caused the issue reloaded Blackberry Link as well. All the previous setup is the same. However, when I go to the Configure Calendar page, it indicates "Calendar (This computer only) and I am not able to modify it or delete it This is the correct folder none the less.
    I thank you in advance for any help or advice on how I can solve this.

    Seems it's a known issue with no resolution yet.

    I would highly recommend uploading your calendar to an email/cloud service like Outlook.com and then adding the account to the Q10. The calendar items will sync nicely between the device and Outlook.com. Additionally, you will be able to have that data on whatever device you use, or multiple devices. I made this move a while back and couldn't be happier.

  • My Iphone does not want to charge with laptop. What can I do?

    Hello,
    Last August I bought Iphone 4S and i am currently in another country for the summer and I wont be back until september which meqns my 1 year waranty is over and my Iphone is expreincing problems with speker sound and it wont charge with laptop. I am afraid that if I go to a local apple store they wont accept the Iphone due to the waranty. So what can I do? please help and thank you.

    Does the iPhone charge when connected to the power adaptor?
    Are you connecting the iPhone direct to a USB port on the computer - not being connected to a USB hub of any kind?
    The local Apple Store can and will run a hardware diagnostic on the iPhone to determine if this is caused by a hardware problem at no charge regardless if the iPhone is no longer under warranty and purchased in another country.

  • Export contacts in CSV, Excel or other format.  I DO NOT want to sync with an email account.  This is for an exemployee who just wants names and numbers in a simple format.

    I have the iPhone 4S, iOS7.0 of an ex-employee.  That person would like a list of their contacts from the phone.  I DO NOT want to sync with another email account, just a simple listing of the contacts.

  • I have some content in my library that I do not want to sync with my ipod touch. The content has previously been synced and I want to remove it without deleting it from my itunes library. Is this possible?

    I have some music content in my itunes library that I do not want to sync with my ipod touch. The content has previously been synced and I want to remove it without deleting it from my itunes library. Is this possible?

    Hi Pez,
    iTunes in the Cloud is not iCloud. Any songs that you have purchased but have not downloaded (or have deleted), go to iTunes in the cloud. The setting I mentioned will show all of your purchases in the various views in the Music app, whether they are on your device or not. If you turn that setting off, you will only see items that are actually on your device.
    Glad to hear the second sync worked! But if they all start appearing again, make sure that setting is turned off
    Cheers,

  • I orginally sync my Ipad with another computer, now I want to sync with another computer

    I originally synced my Ipad with another computer, now I want to sync with anohter computer, I don't want to erase my Ipad and sync with my Ipod.

    This is an extract from one of our senior participant; hope he doesn't mind me reproducing it here
    Syncing with new computer
    1) Without connecting your iPad to your laptop, start iTunes. Click on Edit. Click on Preferences. Click on Devices. Check the box next to "Prevent your iPod etc. from automatically syncing." Click OK.
    2) Now connect your iPad to your laptop and start iTunes.
    3) When iTunes starts, right click on your iPad under Devices in the left column. Select Transfer purchases etc.
    4) After it finishes transferring all your apps to your new laptop, right click on your iPad and select Backup your iPad.
    5) After it finishes backing up your iPad, right click on your iPad and select Restore etc.
    6) After it finishes restoring, left click on your iPad , then click on the Apps tab on top, and check the box next to Sync Apps, then click on Apply below.
    If everything on your iPad looks good after the sync, go back and click on Edit / Preferences / Devices and UN-check the box next to Prevent your iPod etc. The only other thing you may want to check is if your contacts, bookmarks, etc. are syncing correctly now. If not, go to the Info tab after connecting and make sure you indicate which features you want to sync with what sources.

  • I have a Powerbook G4 running on OSx version 10.4.11.  I would like to get an iphone, but non-seem to sync with my computer.  Is there any options for me?

    I have a Powerbook G4 running on OSX Version 10.4.11.  I currently have an Iphone 3, but it cannot sync with my computer because it reverts back to a version so old that I can't even text photos.  (I have itunes 9) I would like to get a new phone because mine constantly freezes up, but I figure what's the point of getting an iphone if it won't sync with my laptop.  I can't even listen to music on my iphone! Is it possible to get an Iphone 4s to sync with a G4 Powerbook? 

    Hello,
    Sadly not as an iPhone 4 running iOS 6 or above needs Mac OS X 10.6.8 or higher to sync in iTunes.
    Mac OS X 10.6 is not compatible with an PowerBook

  • My iphone 4s is no longer syncing with my computer.  Why? My software on the computer IS the latest version.  Iphone 4 cannot be updated due to lack of storage

    My iphone 4s is no longer syncing with my computer.  Why? My software on the computer IS the latest version.  Iphone 4 cannot be updated due to lack of storage

    What happens when you try to sync? Do you see any error messages? Which software on the computer are you referring to, iTunes? The latest iTunes is 11.1.3. If you cannot update the phone due to lack of storage, you will need to delete some content from the phone.

  • ITunes 12.0.1 now just "hangs" and does not complete the sync with my iPhone (iOS 6.1.6).

    Hello all,
    I've seen similar posts earlier in Apple discussions, but I haven't come across a definitive answer yet…So, let me ask again:
    Up until 6-7 hours ago, iTunes 12.0.1 was working perfectly well including syncing with my iPhone (I use an oldie but a goodie and it suits my purposes, iOS 6.1.6, 3GS).  Specifically iTunes now "hangs" and will not complete the syncing process with my iPhone. It get to "2 of 6" in the backing up process, and then the spinning beach ball appears. I keep my iTunes library on a separate external HD (USB).
    Even if I only want to launch iTunes 12 to use it (and NOT sync), the application freezes.
    In similar posted questions, "Linc Davis" has asked that the user run a diagnostic using the Terminal utility.  I have done this, and I paste the results below.
    Any help with this is appreciated!

    Dear Linc,
    Thanks, once again, for repeating yourself by sending me the message above (a message you have sent to MANY users with this problem)!
    However, you give me this great opportunity to say two things:  1) YAHOO! I fixed the problem, and 2) I want to share how I did so because I hope it helps others.
    With the help of reading info at this website http://osxdaily.com/2011/09/22/fix-the-itunes-library-itl-cannot-be-read-version -error-when-downgrading-itunes/, I followed this procedure:
    1) I deleted the iTunes 12.0.1 app from my computer
    2) In addition, in reading related details at the website above (i.e., by clicking on links on the page AND scrolling to the very bottom to view links to related articles), in my iTunes library folder, I changed MY CURRENT "iTunes Library.itl" to "iTunes Library.old", as the website advises. The current .itl file was the one being used by the iTunes app I had just deleted from my computer.
    3) I went to the "Previous iTunes Libraries" folder and dragged a copy of the second-most recent .itl file to my desktop (for me, this file was "iTunes Library 2014-07-23.itl").
    4) I re-named it to "iTunes Library.itl"
    5) I then dragged a copy of the file in step #4 to my iTunes folder (the folder in which you now also have the "iTunes Library.old" file).
    6) I closed all remaining apps on my computer that were opened and I restarted it.
    7) Now, you don't have any iTunes app on your computer, so I downloaded a .dmg of iTunes 12.0.1.26 and installed the app (for example, you can download from here: http://www.macupdate.com/app/mac/5661/apple-itunes.
    8) Once installed, I opened iTunes and immediately I got the dialogue box, "updating iTunes library" -- THIS TOOK FOREVER AS I HAVE CLOSE TO 1,000 SONGS + OTHER ITEMS IN MY LIBRARY!
    9) I patiently waited until the library update completed, but it DID COMPLETE.
    10) Viola!  iTunes 12 is not "hanging" (or freezing) any longer.  I can navigate around the application.
    CAVEATS:
    1) Before I first deleted "the corrupted" iTunes 12, I was able to open the Preferences panel, go to "Devices", and check the box that stops the app from syncing with my iPhone.  This setting seemed to carry over; thus, I have not tried to sync yet…WISH ME LUCK!
    2) After going through steps 1-10 above, I didn't immediately have Internet Radio available in the application (i.e., I didn't see it), but it is now showing up and it works!  I just had to wait for a few minutes...
    3) I also use iTunes Match, but I haven't turned it on yet in the newly installed app. On the iTunes Match page, it says, "Add this computer" or "No thanks". So, the app is behaving as if I'm just beginning to use iTunes Match for the first time.  Later, I will click on "Add this computer", and I hope it goes smoothly!
    4) This isn't a caveat, but I think I should say: my iTunes library is on an external USB HD (I have to say THANK GOD for that). Obviously, this has implications for doing steps 2 to 5 above. The newly installed iTunes 12 app had no trouble in finding where my library is (I had it set up this way back when I was using iTunes 10).
    5) One last piece of advice: Make sure that when you plug your iPhone into any other computer only to re-charge but the iTunes app on that computer wants to sync with your phone, you DON'T let it sync.  First, you should go to Preferences in the iTunes app and click on "Devices". Then check the box that says, "Prevent iPods, iPhones,…….from syncing automatically."  After that, you would be able to plug in your iPhone to another computer to re-charge it.
    FINALLY:  I THANK EVERYONE WHO WAS WILLING TO SUGGEST SOLUTIONS TO ME REGARDING THIS PROBLEM!  I see that MANY users are having this difficulty, so I thought it would be fair for me to share how I resolved the issue -- my iTunes is running fine now...

    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).
