ITunes using 50% CPU

I need some help. It seems that iTunes is taking up over 50% of my CPU and is fragging everything ese to a massive slow down. I have tried all of the suggestions on the iTunes support page, to no avail. Has anyone been abel to resolve this? It seems related to the upgrade to 7.6.2.
As soon as I go into iTune the CPU pegs and iTunes is horribly slow.

edit: warning: for some reason iTunes 7.0.2.16 doesn't want to recognize (authorize) my purchased music. I will update this if I find out how. I tried deauthorizing my computer but it wasn't successful at deauthorizing itself.
I found out how to fix it; go back to a previous version of iTunes. I found an old version of iTunes at http://www.oldversion.com/program.php?n=itunes (I just downloaded iTunes 7.0.1 according to that website--which is actually 7.0.2.16).
I had to export my library before uninstalling iTunes. Then after uninstalling the new one and installing the old version I just imported my exported library file from the previous sentence. It uses considerably less CPU now. With iTunes open and visible it takes ~15-20%. If I have the option selected to minimize to the system tray and I minimize it, it uses ~5%.

  • ITunes using 95% CPU?

    I'm running iTunes 10.7, Mountain Lion, on an iMac with 4gb RAM. Periodically while running iTunes my computer gets really sluggish; a look in Activity Monitor reveals iTunes using over 90% of the CPU. If I close and restart iTunes, it behaves itself for a while, but this can happen even if iTunes has not been open for long. What's going on, and is there anything I can do to fix it?

    I'm having the same trouble! 
    My difference is that I'm running Lion (10.7.5) on a Mac Pro with 12GB RAM.  I have oodles of space on all drives (total of about 13TB).
    After iTunes is running for a  few minutes  the entire system become VERY sluggish!
    The display mode does not seem to matter at all.
    Screen updates for  pointer interaction, window dragging, and etc. slows to about 2 or 3 FPS (slow!)  Even typing this right now is slow slow slow!
    UG!  Yet another wonderful Apple software update!

  • Poor audio quality - iTunes uses 100% CPU for 15-20 seconds

    About 6-7 seconds into an MP3, iTunes pegs my CPU to 100%, and the audio lags or shuts off completely. Protected AAC files play without issue. Converting the MP3 to AAC does not help: the audio and CPU give the same results. Winamp, WMP, and *even QuickTime* can play the same MP3 files without issue. It is only MP3s and only iTunes. I have uninstalled my antivirus, but that did not help. I removed all start up applications and closed any program that wasn't essential to the computer's operation. I have even killed non-essential processes. These files have played in in iTunes previously, it has only been in the last few months that I have had a problem. I have uninstalled and reinstalled the latest version of iTunes just this morning. Nothing has helped, and I'm not about to reformat my PC just to see if that will help when these files play just fine in all my other media players.
    So, to recap:
    - Problem is ONLY with MP3s -> M4Ps play fine
    - Problem is ONLY iTunes -> Quicktime, Windows Media Player, and WinAmp play the MP3 just fine
    Ideas?

    I have no idea what is causing this, but iTunes is rather sensitive to ID3 tag versions - the usual symptom is that it will not play the file.
    As an experiment try selecting an MP3 track, then right click and select convert ID3 tags. Convert to "None".
    I would do this on a copy of the file.

  • Why does iTunes use 100% CPU all the time, hogging my Macbook Air?

    Decided to post this here instead of the iTunes forum, since it might be related to hardware too.
    New owner of a 2011 13" Macbook Air, core i5 based.
    My problem started about 1 week ago, after it had run out of power completely one day. At the first boot after that it was incredibly sluggish, totally unusable. After waiting for 5 minutes and still being unresponsive, I turned it off and then back on. Then it booted fine. HOWEVER, ever since that time I noticed the following behavior:
    - iTunes stays at 100% + CPU all the time, mostly between 100-120%. Even if it's not playing. Even when I deleted the entire library and left it empty.
    - iStats reports CPU idle between 50-65%. However, CPU temperature is still about 55 degrees C (which, I think, is far less than what it should have been with 50% idle cpu). I can confirm the low temperature by touching the chasis.
    - the cursor freezes and jumps every few seconds, making the mac kind of unusable with iTunes open.
    This has been going on for 2 weeks now. The problem goes away every now and then (iTunes sometimes goes back to regular CPU usage of 3-5%), but most of the time it's there.
    Help!
    P.S.
    Mac OX X 10.7.2
    iTunes 10.5.2

    Cee Pee You, is a OS modification. Apple recommends that you un-install these prior to a OS update because Apple makes changes to the OS all the time which breaks programs like these.
    I avoid Unsanity LLC products like the plague. Notice the company is a Limited Liability Corporation (LLC), which makes it difficult to sue the company in case of a defective or malicious product. So the risk using their products is all yours. Their APE framework modules have been used for malicious purposes because anyone can write a module that uses the APE framework.
    I also avoid installing anything that requires a administrative password unless I completely trust the source, like Apple mostly. That admin password is the key to the security of our machines, not to be given out lightly or carelessly.
    You'll have to contact Unsanity's [email protected] because what I'm reading online is it's very difficult to remove as it doesn't "exist".

  • Itunes uses 100% cpu

    There has been a great deal of discussion and comment about Itunes consuming 100% of CPU on my windows laptop. I have seen various solutions but have to say none of them actually work for me. I have disabled the Apple exe for itunes startup but of course this is not a solution its just sticking plaster. Does anyone know of a certain way of resolving this please.

    Close your iTunes,
    Go to command Prompt -
    (Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
    (Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
    In the "Command Prompt" screen, type in
    netsh winsock reset
    Hit "ENTER" key
    Restart your computer.
    If you do get a prompt after restart windows to remap LSP, just click NO.
    Now launch your iTunes and see if it is working now.
    If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

  • Itunes uses half cpu on xp

    iTunes 10.5.0.142 is using 1/2 of the memory on my dual core HP using XP Media Edition.  Read some forums and found relief by using command "netsh winsock reset".   This removed the AppleMobileDeviceService.exe temporarily but had the side effect of impacting Internet Explorer - it couldn't find the server.   As soon as I rebooted and the service ran again, IE worked fine.  Anyone with better solution?   Reluctant to delete iTUnes and reinstall.  Others are having same problem, is Apple addressing this?

  • New iTunes uses 100% CPU

    I hate the new iTunes. It is consuming 100% of my CPU. Anyone else experiencing this?

    Oh another thing:
    It does step 1 ok (backing up) but when it starts downloading apps (step 2) is the problem. The first few apps end up downloading but iTunes freezes like 5 times during the process... After a few apps comes the white screen and everything... Once the iPod is removed and iTunes it closed, the background comes back and everything  goes back to normal. Nothing is erased from the iPod either.
    Thought that would help.

  • Converting to MP3 causes iTunes to Not Respond while using 50% CPU usage and makes my computer stutter

    Anytime I attempt to "Createa an MP3 Version" of a track, it will take a REALLY long time to work.
    Right now I am attempting to convert an audio book I have which has 88 tracks.  Once I start to convert anything more than 1 track at a time, iTunes immediatly becomes "Not Responding" and takes up about 50% of my CPU the entire time.  It seems like it's doing something in the background but it won't even update the screen anymore, creating weird effects on my screen (Ghost menu bars show up at the top of my screen, etc.).  In addition, once iTunes becomes non-responsive, my entire computer starts to "stutter" meaning that every other second everything momentarily hiccips and stop for a split-second.  This means that while iTunes is converting any multiple MP3 files, if I drag the mouse across the screen, it stops every other second.  Any videos that I try to play pause every other second briefly.  Basically, my computer becomes almost unusable.  Plus, while iTunes is working in the background, different programs randomly jump to the front of the screen.  I will try to be using my web browser while iTunes is working in the background.  Then, suddenly, iTunes pops back up to the foreground in front of my browser (put still won't be responsive to clicks).  My notes program will also flash windows in front of my web browser while surfing, again, only when iTunes is running in the background. 
    I really don't understand:
    1.  Why it takes so much time to convert any file to an MP3 file.  Even converting a single track takes a few minutes.  I'll let my Macbook Pro (with Windows) sit for HOURS upon hours trying to convert the 88 track audio book and it always freezes up and never comes back.
    2.  Why iTunes becomes non-responsive so quickly and won't allow the screen to update once it starts "thinking."  It caps out around 50% of my CPU power so it's not like it doesn't have the headroom to refresh the screen while it works.
    3.  Why does iTunes' working in the background affect every other program I am running?  I don't mind if it uses up CPU cycles in the background, but if it makes my computer unusable while doing so, it's really not worth it.
    I should state that I love Apple products (even though I use Windows on my MBP for school purposes).  However, I absolutely DREAD having to do anything with iTunes anymore because it has become such a hog on my computer.  Someone please tell me that there is something wrong with my iTunes and/or a setting I should change.  I have already re-installed iTunes from scratch before and that didn't help.

    Not a solution, but if the Podcast feed is dormant, why not unsubscribe?
    As to the file structure for media on the device it is deliberately obscured as a countermeasure to casual piracy. See Recover your iTunes library from your iPod or iOS device. Content put on the iPod by a non-iPod aware product is going to treat it like any external drive. The iPod firmware won't read that media.

  • ITunes will uses 100% cpu and will not close in OSX Lion

    When I start up iTunes, after a few minutes, the fan kicks on and Activity Monitor shows that it is using 100% CPU. The fan kicks up and the MBP gets warm. I have to force close to get it to shut down. iTunes match is constantly running, so maybe that has something to do with it?
    I'm not running it in Mini Player mode or anything like that, so I'm not sure what's causing the problem. Any thoughts on how to diagnose it?

    I also have this problem which has been getting worse with recent successive updates of Firefox. As a long-time user and advocate, I am about ready to look for an alternative browser. Firefox will not close and exit properly, requiring direct cancellation through Task Manager; starts up very slowly (often 1 to 2 minutes); and frequently locks up the CPU with 100% of cycles while doing NOTHING; offers to restart crashed sessions, but cannot recover and reload those sessions; will not operate correctly while any other application accesses the internet, like uTorrent. Firefox is set to delete cookies, etc. whenever the session closes, sqlite database is vacuumed regularly, CCleaner regularly wipes remaining accretions, and disk is defragged. Currently running 3.5.5 but will NOT upgrade until this problem is solved since later builds report the same problems. I know several other users who have experienced the same problem and I can no longer automatically recommend Firefox to users and clients. Is anybody paying any attention to this problem? What is being done to address this fault? Why is there no response to the original poster? Is this really a support forum or just a way to preoccupy and distract the users who suffer this malfunction? Wireless 54Mbps connection. No Adobe Flash, QuickTime, MS Silverlight, etc. installed on this machine. Firefox 3.5.5 with the following add-ons:
    Aardvark 3.0
    Adblock Plus 1.2.1
    Adblock Plus: Element Hiding Helper 1.0.6
    Free Download Manager plugin 1.3.4
    Highlighter 0.1.4

  • ITunes Using Up 100% of CPU

    For some reason iTunes was using 100% of my CPU, for some reason I thought the iTunes library may have been corrupt, making iTuunes use 100% of my CPU when I started it. So I deleted my .itl file and imported all of my music again, so now all my songs are in iTunes and it seemed to work. Then, as part of my settings, I turned on the souncd check, now iTunes uses 100% of my CPU and doesn't respond when I open it, how can I fix this?

    Sorry. I did a search, and a lot of threads came up. The one I chose, I thought, explained WHY it happened.
    Maybe you'd get answers more helpful to you, if you went throught the search results.
    Sorry I wasn't of any assistance.

  • Solution: iTunes 10.5 using 100% CPU / Not backing up your iPhone.

    This solution has been documented on this forum by several people, but the solution is usually deep in multiple threads.  I really don't know who came up with it first, but it does indeed work.
    I had an issue with iTunes.exe, APSDaemon, and AppleMobileDeviceHelper.exe using 100% CPU per core.  (Showed as 25% in Task Manager.)
    I could not backup my iPhone and the CPU spike happened as soon as iTunes 10.5 was started on Windows 7 Home Premium x64.
    This solved it.
    Sounds stupid but works:
    1. Quit iTunes.
    2. Start an elevated command prompt (Start Menu -> All Programs -> Accessories -> Right Click "Command Prompt" -> "Run as Administrator")
    3. Once in the command prompt, type "netsh winsock reset" and hit ENTER.
    4. Reboot your machine.
    5. Restart iTunes.
    6. ???
    7. Profit!         

    The netsh winsock reset resolved both the problem of AppleMobileDeviceService.exe using 100% of my CPU and the blank iTunes blank store issue. 
    XP Pro user here that had gone through the detailed step-by-step process of uninstalling iTunes as described on the support page but both problems still existed. 
    Glad I saw this. Thanks.
    Now on to :

  • ITunes uses 30% of CPU when paused?

    Since my update to the most recent iTunes, it's been using 30% of my CPU only when songs aren't playing. When anything's playing, it uses 0%-1% of my CPU, but when a song is paused or stopped, it uses 27 to 30 percent. I'm running Windows XP Home and I'm using a Core 2 Duo E6600 OCd to 3.2GHz. It doesn't do it when I first open itunes or even after the first pause... but after 5 minutes or so, it'll start doing it.
    Anyone know how to fix this?

    This is the forums for iTunes for Windows mate...
    Check out the Mac equivalent here:

    My iTunes used to crash a while ago because NOD32 kept stopping it from working properly. Does it still do this without NOD32 (or any other Antivirus) running?

  • I upgraded to iTunes 10.5 on XP and now it and applemobiledeviceservice.exe use 100% CPU. How do I fix this?

    I upgraded to iTunes 10.5 on XP and now it and applemobiledeviceservice.exe use 100% CPU. How do I fix this?

    When I called Apple Support to ask about the 100%  CPU usage, they wanted to charge me because my Ipod was out of warranty.  I insisted on talking to someone and finally got to talk to a software engineer for free.  He said that he had never heard of the problem in his three years at Apple.  Nonetheless, he sounded really interested and suggested that it might be a conflict with anti-virus software.   I deleted the antiviruse and that DID NOT HELP AT ALL.
    It seems as if Apple could care less.    There is no official response.   Their primary response is to look at the Forum.   At least you find out that the problem isn't your fault, it really is Apple!!!!
    So far the best solution is just to delete iTunes and use Mediamonkey to sync your pod.
    Apple, please fix this!!!!!

  • Itunes 10.4 using 100% CPU

    Since I upgraded to Itunes 10.4 it is comsuming 100% of my CPU.

    FYI:   Following D528's note OKAY HERE IS THE FIX in
    https://discussions.apple.com/thread/3200832?start=60&tstart=0
    which essentially is an uninstall of Apple software on the system and reinstall iTunes 10.4 with a couple of sequence and some specific reboot instructions, worked OK.   (I skipped his step 8)
    It resolved the iTunes and AMDS cpu consumption on my Windows XP system.
    I can now connect to the store.   Synced with iPad and iPod nano.   No CPU hogs.  I did not reinstall Safari, so don't know if it resolved that.   Podcasts updates and app updates worked.
