ITunes 10.2.1 sync using whole core

Hi,
I'm sure this has been asked but wasn't able to find any answers.
Basically I'm syncing my iPod to iTunes 10.2.1 on my macbook (2.1 GHz Core 2 Duo, 2.5GB RAM running Snow Leopard 10.6.6). I've noticed lately that not only is it taking an absolute age to sync a few hundred items, and as well as that the application is using up an entire core (sometimes upwards for 120% CPU in total). I'm assuming this is not expected behavior, is anyone else experiencing this or have found a solution to the issue?
Cheers

I'm having the same issue. Today, iTunes has decided to spin the CPU for no apparent reason, and become 'hung'. It hasn't been syncing or anything... I just woke the computer from sleep. Before the computer was put to sleep, iTunes was idle in the background.
Not sure what's going on, but iTunes 10.2.1 seems far from ready.
On a side note, the only thing that looks like it could be related is this (in system.log):
Mar 17 10:07:14 Clarity configd[19]: Kernel iTunes com.apple.powermanagement.applicationresponse.timedout 30000 ms
And the associated power management log item:

My 6th Generation Nano Shuts down my Thinkpad, I've tried uninstalling iTunes, turning off auto sync'ing and restoring my ipod, but every time I plug in my iPod, my whole pc goes blue and then reboots in safe mode. Please Help. Thanks.

Hello kidmango,
I am going to have to agree with planb77. Look into other drivers in your computer causing the issue, not just the nano's drivers.
It is possible that security software is the culprit. Use this:
iTunes: Troubleshooting security software issues
You may have to restore your computer to a previous point. From before the issue started. Contact computer manufacture or Windows for steps, or do a search with a search engine.
I would test the ipod on a known good computer to see if its the ipod is the issue. My gut says no. You can set a reservation at an Apple Retail Store. Apple.com/retail .You can also test a known good ipod on your computer.
Hope this helps.

Photos loaded directly onto ipad air do not show up on PC anywhere when synced using itunes

Photos loaded directly onto ipad air using Apple camera connection kit, do not show up on PC anywhere when synced using itunes

They won't show in iTunes (iTunes is only used to copy photos to a device, not copy them off), but you should be able to copy them off either manually via My Computer (the iPad should show as a camera) or via windows camera wizard or windows live photo gallery depending upon your OS version.

The screen is black . i can.t get it to respond.Power + home soft reset didnt work. Itunes could detect any sync apps. I used my home phone to call my iphone and on my home phone i can hear the calling tone.But my iphone didn't ring/screen did not light up. Its a iphone 4. Any ideas how to fix this?

If the basics (restart, reset, restore from backup, restore as new) don't work, you'll need to bring the phone to Apple for evaluation

I recently updated and restored my Iphone on a Mac. My music was erased, therefore, I am trying to sync all of the music from my computer into the iPhone, but it says that I need to use the original computer/itunes in order to sync, but it is the same computer and iTunes account. The error reads: The iPhone, "Name" is synced with another iTunes library. Do you want to erase this iPhone and a sync with this iTunes library? If I click "Erase and Sync," will it delete my contacts, apps, etc?

I don't want to sync what is on my iPod to my iPad. (I have a 32gb iPod but only 16gb on iPad. The iPod I use mostly for music.) I can't seem to add the films I have downloaded onto iPad to iTunes. If I could do that, I could erase them from iPad to create more storage.
This is intensely confusing, sorry.

Question.....
"I own an iPhone4, an iPod 3rd generation and an iPad 2. I use the same iTunes library but unfortunately synced iPad with a different computer before syncing to my own. Do I risk losing the films/apps I've downloaded onto my iPad if I sync with my iPod?"
Answer.....
Yes you will lose the films that you downloaded to the iPad when you sync with your own iTunes unless you transfer the purchases into your own iTunes library. Were these movies that you purchased? If so, you might be able to download them again for free. Do you have multiple computers that you sync from or is this someone else's purchased content?
You can select whatever you want to sync to all of your devices in iTunes, you do not have to sync the same content to all device.

How can I use 2 iPhone 4's on same iTunes account, but NOT sync same contacts?

How can I use 2 iPhone 4's on same iTunes account, but NOT sync same contacts?

They need to be registered under different Apple ID's. The initial Apple ID is set when you first start the phone up. If you've already registered the phone to the iTunes account, back it up to your computer, and then have iTunes do a factory reset. Go to www.icloud.com, log in with your current Apple ID, select "Find My iPhone," choose the iPhone you want to dissociate from your primary Apple ID from the upper left, and then click the little circled X ("remove").
When you start the phone, it will have you go through the setup process again, at which time you need to create a unique Apple ID for the device. You can then restore it from your iTunes backup to get back your apps and other settings.
Whenever you use the iTunes store, use the login information (Apple ID and password) that you were using before. Basically, the second Apple ID that you created is purely used for accessing iCloud services, which includes synchronization of contacts, iCal events, and other such things.

I recently created a new apple ID
Bad idea.
Content bought with an Apple ID is forever associated with that Apple ID. Apple will not transfer content from one Apple ID to another and Apple will not merge Apple IDs. Unless you are prepared to forfeit all the previously purchased content and buy it all again with the new Apple ID, you will need to maintain the old ID to update and redownload your content.

Call Apple's online store's telesales agents: 1-800-MY-APPLE (1-800-692-7753) or Customer Service and Sales Support at 1-800-676-2775. For Lion you'll get a redemptions code via e-mail and need to DL from the Mac Apple Store (requires SL 10.6.6+).

My wife had an iPad for a year and synced to our computer with no problem. I recently received an ipad2 and when I tried to sync using separate apple and iTunes passwords, under her computer user name, it appears I over-road her account and synced all her apps with my apps on my iPad. I then set myself up as a new user on our computer and tried to sync. I now get the error that my iPad is synced to another library. How can I start over without erasing all my data on the iPad?

Go back to her login. Unless you deliberately erased apps, they should all be there, both yours and hers! Then, you need to set up each iPad separately. You will notice that they have separate names for that very purpose.
There is no problem with multiple Apple IDs on the same iTunes on the same computer except... Apps are permanently associated with the ID that was originally used to obtain them. If you choose to update an app from inside iTunes and you're logged into the "wrong" ID, you must log out and back in again.
On the bright side, you can configure either or both iPads to sync with apps and music and movies, etc. from either or both IDs. Further, if you choose to update the apps from the iPads themselves, there is no need to log out/in. The device handles that. All you need is the correct password. In my case, I use the same password for both IDs to make things easier.

How do you get your music on your phone without syncing the whole iTunes library on your phone?

How do you get your music on your phone without syncing the whole iTunes library on your phone?

Are you syncing to a different computer? Iphone will sycn with only one at a time. Syncing to another will erase the current content.
Otherwise, just select what you want to be on the iphone under the music tab and sync. What do you care if it erases? You will be syncing what you want to the iphone.

ITunes 11.4 bug when used with OS 10.6.8 - won't sync or backup iPhone

I actually just wanted to post this in case Apple monitors these boards. iTunes 11.4 says it's compatible with OS 10.6.8 or later, but there is a bug in it when you're running OS 10.6.8 that prevents you from backing up or synching your iPhone (in my case, a 5s). Doesn't matter what iOS you're running. If you attempt to backup in iTunes 11.4, it immediately ends the backup and only displays "Other" content being stored on your phone. Also, the "Sync" button is greyed out, so you can't even attempt to sync.
No amount of restoring (even a DFU restore) or reinstalling iTunes 11.4 will fix this. The solution is to delete iTunes 11.4 and its related files and to reinstall iTunes 11.3.1, at least until Apple gets the bug corrected. After hours of restores trying to resolve it, I followed this process and it completely solved my problem in about ten minutes. I found the solution with instructions in this thread:
Upgraded to iTunes 11.4 and now it won't sync my iPhone 5s-sync button is greyed out.
Thanks to cwa2, enee and Zak for supplying the solution. I've also summarized the steps here.
(1) Use this link to download a copy of iTunes 11.3.1:
http://www.v3.co.uk/v3-uk/download-review/1957301/apple-itunes-for-mac-1110
(2) Delete the following iTunes 11.4 components (they will be replaced when you install iTunes 11.3.1) by dragging them to the Trash:
/Applications/iTunes.app
/Library/Frameworks/iTunesLibrary.framework
/System/Library/CoreServices/CoreTypes.bundle/Contents/Library/MobileDevices.bun dle
/System/Library/Extensions/AppleMobileDevice.kext
/System/Library/Extensions/AppleUSBEthernetHost.kext
/System/Library/PrivateFrameworks/AirTrafficHost.framework
/System/Library/PrivateFrameworks/CoreFP.framework
/System/Library/PrivateFrameworks/DeviceLink.framework
/System/Library/PrivateFrameworks/iTunesAccess.framework
/System/Library/PrivateFrameworks/MobileDevice.framework
(3) Some people have had trouble seeing the contents of the CoreTypes.bundle to get to the MobileDevices.bundle. You can access it this way:
In the Finder, select Go To Folder under the Go To menu (or Shift+ Cmd+ G)
Type in: /System/Library/CoreServices/CoreTypes.bundle/Contents/Library/
The MobileDevices.bundle will be displayed; drag it to the Trash.
(4) Empty your Trash.
(5) Install iTunes 11.3.1, and go back to living your life. Remember, do not upgrade to iTunes 11.4 again until you're certain the bug has been resolved.

In Reply to all fellow Apple fans: It is great that someone found a work-around to the iTunes 11.4 no syncing problem. I think that is fine for the short term. And I am really glad that we customers have a forum to share information and experiences regarding Apple's products. However, as someone here said, we are all customers; and posting a problem here "IN HOPES THAT APPLE READS THESE POSTS" is NOT a way to resolve this issue or any issue.
PLEASE CONTACT APPLE: Apple Service Center: 1-800-275-2273 - Once you get a ticket number then and only then is this documented and then Apple can follow-through and alert the engineers who will fix this.
The "CWA2" work-around band-aid does several things in addition to reverting back to iTunes 11.3.1. :
1) It ensures that Apple continues to know nothing of the problem.
2) It ensures that the faulty code that is within 11.4 remains there and is perpetuated into future versions.
3) It ensures that YOU can never upgrade to future versions. (If the resident faulty code remains and perpetuates)
So once you have reverted back to 11.3.1, the problem APPEARS to have gone away (FOR YOU) but you have not solved the problem.
Again, respectfully,
1) Sending feedback to apple (using the "Report Bugs To Apple" menu item in Safari will get the information to someone, somewhere and add it to the pile of issues, complaints, suggestions, etc.
2) CALLING the Apple service/support Center at 1-800-275-2273 will put you in touch with a real APPLE person who will begin the process of documenting and forwarding this issue on to those who will fix it.
and
3) emailing Apple directly will make sure that they get the information.
lets get this fixed !!!!!!!!!

I've burnt a digital copy of 3 blu ray dvds onto my iTunes, but i cant sync them to my iPad-an error message says device needs to be authorized, but its only authorised to this computer, i've never tried to use it on any other! Can anyone help?!

Thanks for your reply, but you might have misunderstood it a bit. I'm NOT trying to buy a movie. ****, I'm not even in the actual Apple Store, when this happens I'm in the library not the Store part of iTunes.
To clarify - I have purchased a physical copy of a movie which came with another physical copy which contains the digital copy. The digital copy is on the DVD, all I need is just to transfer this file to my iPod Touch, for example, I'm not trying to download it from the store or repurchase it and it's not any gift code that I've received, the digital copy is on the disc. This is the first time ever that I've purchased something on a disc and I'm not allowed to access it because the disc hasn't been purchased within my country.
So again - I'm not attempting any purchase or download any purchased digital copy - it's on a DVD I own physically so... why is even the region of my Store relevant, the code I enter is (as I assume) just supposed to check if it's a legal genuine copy (which it is, as I've said - there are 6 discs in the pack: 3 movies on 3 Blu-rays and 3 DVD containing these digital copies of them). If I own it, I think that's proof enough that I have the right to use it. I just don't get it. I fully agree with you and understand your point if there was any purchase going on here, but it's not, it's just - I put a disc into my computer and I can't access it

Need Help Syncing Using iTunes

How can I control what gets synced using ITunes? Usually I only want to sync my Outlook Contacts and Calendar between my computer and iPhone, and occassionally some music, but my apps get synced as well.

click the black/white square button on the top left of your screen, then click 'show menu bar'.
In the menu bar, then click 'view' and then 'show side bar'
Now it might look somewhat familiar.
After this: http://support.apple.com/kb/ht1386
Good luck
