Itunes 11 high CPU

Since downloading iTunes 11 I've noticed a considerable drop in computer functionality and speed whenever it's running. Even if it's just playing music. It's eating more CPU and Memory than ever before. Is this a normal thing?

Yessss! i' ve finally found the issue !
The problem was with "smart play lists" i dunno how you call it in english, but i' ve created a long time ago a smart playlist named "unread" because the "all random" function is not so much random for me, as they play some tracks more often than others...
With as criteria " numbers of play = 0 " so one title is played one time!
By using my brain as good as i can, i told myself " what itunes do when a song ends and then go to the next?"
It wrote something on the smart play list or something like that
Then test from "play all random" = no more issue !
Then deleted my smart play list and recreate one identical = problem solved !
norbml : i hope this help you

  • ITunes high CPU usage

    Every single time I delete or add any item to iTunes, the CPU hits 100%, sometime for over 45 minutes.
    - iTunes does not respond to 'Quit'
    - Everytime you 'Force Quit' it comes right back.
    - Tried shutting off Ping, signing out of iTune Store - nothing!
    - Looked at all similar threads and discussions, unfortunately nothing helps, you just have to wait it out.

    Quickly doublechecking something ... you've tried disabling wireless syncing?

  • ITunes high cpu, CoreAUC problem

    Hi,
    Running iTunes 10.4.1 on a 2011 MBA and it's constantly spiking the CPU. I emptied my library, created a new library, tried another account, but the problem won't go away. I don't use any iTunes plugins.
    I've sampled the iTunes process in activity monitor and I see many, many messages like these:
        +                               ! : | + ! : 7 ???  (in CoreAUC)  load address 0x7fff931d9000 + 0x5e6b64  [0x7fff937bfb64]

    Anyone know how I can troubleshoot this problem further ?
    Thanks !

    I am having the EXACT same problem with my MBA 13" mid 2011 ( 128 GB i5 version ).
    I can't find an solution for this and am pretty new to mac OS. Went back to the seller and he said i should format my disk and reinstall everything from a fresh OS copy. Tried it but it didnt fix anything. Went back and he said i should contact apple...
    Also looked on the internet, and the problem isn't that common apparently...
    Found some things about CoreAUC and i'm not sure if replacing it matters, because i already tried formatting it...
    Hope someone can help!
    Thanks in advance

  • ITunes, high CPU, cant sync photos to iphone4!

    iTunes is hanging/freezing when i try to loade pics to iPhone4, and using 98-100% CPU! HELP!! it stops right before finish! tried 4 times now..

    Im running Vista and it's doing the same thing.
    If you really need to sync your phone, you can.  Just de-select sync photos and hit Apply and itunes will sync everything else just not your pictures.
    Also, I read on forums something about reseting the winsock in the command Promt, that did not work to sync photos.  I am able to connect to itunes store though as some people said they were having problems with that.

  • ITunes 10.6 has High CPU Usage when switched to Mini Player

    iTunes has high CPU usage when switched to mini player. The CPU usage goes to 80-100% when the next song is played in Mini Player. iTunes then stays at high CPU usage.
    Upon exiting mini player the CPU usage will drop back to the normal 0-5% levels.
    This only happens when playing from the main music library; which my library is at 7089 items, 42.04 GB.
    When playing from a smaller playlist such as a smart playlist with about 15 songs in it for example, the CPU usage stays low/normal.

    Do you have any better luck with that if you update to iTunes 10.6.1.7?
    From the notes for the release:
    iTunes 10.6.1 provides a number of improvements, including:
    • Fixes several issues that may cause iTunes to unexpectedly quit while playing videos, changing artwork size in Grid view and syncing photos to devices.
    • Addresses an issue where some iTunes interface elements are incorrectly described by VoiceOver and WindowEyes.
    • Fixes a problem where iTunes may become unresponsive while syncing iPod nano or iPod shuffle.
    • Resolves an ordering problem while browsing TV episodes in your iTunes library on Apple TV.

  • High CPU usage when downloading from ITunes Match

    When attempting to download matched songs from ITunes Match, ITunes utilization spikes to over 70% and makes it almost impossible to do any other function on the computer.  Eventually ITunes fails to respond.  I have tried several remedies including reseting winsock.  Is there any other options I should try?

    Hiya,
    could it have something to do with the write speed/ cache/ram? On a "slow" disk, or one that is nearly full or one that is partitioned, it will take a great deal more ram and cache to "digest" the faster download and write it onto disk. I tend to do downloads to a separate drive. Have you got one? and can you repeat the high CPU usage when downloading / saving to the external drive? I note your drive might have 5,400 rpm, with "just" 8mB cache and 320 GB (quite a few SATA's have 7,200 rpm and 32 mB cache).
    NB: If anything, I found SL more efficient, especially on my 4 year old Macbook, which is running much faster and has got more responsive after installation of (full version of) SL.

  • ICloud Photo not syncing + High CPU process (Win 8.1 pro)

    This is a new persistent issue with my iCloud and I can't figure out how to fix it permanently because I was able to fix it few days ago, but issues return back a day later! So here's the full story...
    I just received a new (AWESOME!!) Surface Pro 3 i5 256 GB tablet with Windows 8.1 professional. I installed iCloud on it as well as iTunes and Quicktime (the basics isn't it?). When setting up my iCloud account first, everything sync up correctly but after a few days (3-4 days), I notice than my Surface tablet are becoming pretty hot and making some fan noise (common Surface issue) when I didn't use it really. So I checked for a high-CPU process and I noticed than "iCloud Photo Stream Downloader" are stuck at 30-35% CPU for an hours ago. Moreover at this point I realized than my photos are not syncing for a few days. I fix the high-CPU process by rebooting, but my photo are still not syncing at all and after a few minutes after reboot, the "downloader" process stuck back to 30-35% and still not syncing!
    So I first try some of the workaround found on the internet like sign out iCloud app, then kill all iCloud related process and delete folder %appdata%/Apple/Mediastream and reboot and sign in... same thing... after a few minutes, high-CPU usage + not syncing! I try to "repair" iCloud installation... same thing (high CPU + not syncing)... I uninstalled iCloud + reinstalled... same thing!
    I finally fix the situation by uninstalling ALL Apple related software (iTunes, iCloud, Quicktime, Apple Soft Upd, Apple Mobile Sup, Apple App Sup, Bonjour, etc) and thereafter deleting all "Apple_xxxx" folders in %appdata% and also remove all registry keys from the Windows Registry related to Apple. Reboot then reinstall iTunes first and then run "Apple Soft Upd" to install automatically iCloud + Quicktime... then reboot, sign in and then the photo finally sync this time and no high-CPU process!
    But a days later... High CPU + Fan noise on the tablet... so checked and the god **** "iCloud Photo Downloader" are again stuck at 30-35% and no more photo sync (I saw the old photos, but not the last day's photo are not sync).
    Anybody experience this situation and know how to fix it PERMANENTLY? I checked at my Apple iCloud LOGS and the only thing I saw that can be suspicious is the last line of the log who's :
    [2472 @ Tue Nov 11 19:45:09 2014] [YSLog ApplePhotoStreamsDownloader.exe] defaults key ShouldLog in domain ApplePhotoStreamsDownloader.exe is (null)
    Please help!!

    In fact I discovered later I have this issue on all my Windows computers... both Windows 7 and Windows 8.1, both MACs (BootCamp) or true PC computers. Except only the Surface Pro 3 tablet seem to have the HIGH-CPU process issue, but all my other Windows PCs stopped syncing too after a few weeks or so.
    I just build a BRAND NEW HP Pro Desktop computer running Windows 8.1 Professional and a few days later iCloud Photo stopped syncing too... this is the straw that broke the camel's back! This PC is brand new and no other software are installed except iCloud, iTunes, QuickTime and Microsoft Office 2013 (Office 365). PC is brand new (1 week old) and iCloud Photos sync is already broken!
    I also have a few Windows 7 PCs at home (HTPCs on TVs) where iCloud Control Panel is installed and after looking at them, they stopped syncing too for a while (many months ago) but I didn't noticed it yet because I don't check photos often on them.
    For now I just give up and disabled the iCloud Photo Sync completely on all my Windows PCs. It only sync between my two iPads, my two iPhones and my two Macs computer (MBPr + iMac 27") and that's it... that's sad, but I'm tired loosing my time with that crappy software!
    PLEASE APPLE!! MAKE ICLOUD FOR WINDOWS BETTER!!

  • Database file + high cpu usage

    this has only started happening since i formatted and reinstalled windows. i have tried using both itunes 6.0.2.23 and 6.0.4.2 and both have the same problem.
    my music library contains 5088 songs, i have tried deleting heaps down to around 3400 and problem is still there (ie i have eliminated number of songs as a factor cause before formatting i had more than 3400 but less than 5088)
    when i play a song in itunes after about 5 seconds my cpu usage will jump to 100% this is on the "system" process, itunes itself uses around 2-5%. i was watching the itunes music folder though, and what it is doing is creating a new temp file (of 7.27mb) then renaming it to replace the current "itunes music library.xml" file. as soon as the xml file is replaced (takes about 10 seconds) cpu usage returns to normal.
    this exact same thing happens when i quit itunes, although it takes roughly 20 seconds.
    i have tried deleting all files in the itunes music folder apart from the base database file, that did nothing.
    i tried removing the entire folder and letting it create a new blank library, then added just 1 album, and it worked perfectly. i also noticed that on my original library most but not all AAC encoded files did not cause the cpu spike, all mp3s did.
    i tried creating an entire blank library and adding all my music back in, it still did high cpu usage so i would assume my current database is not corrupted.
    does anyone know a solution to this? how to stop it recreating the xml file with every song played. the only thing important to me is saving my playcounts, so any solution which does not require losing them would be appreciated.
    also yes i have tried completely uninstalling itunes, for both of the versions mentioned above, also tried updating over the top of the current installation, problem occurs everytime.
    i am running service pack 2, all current windows updates installed, no spyware, no viruses.
    thanks.

    It may be iTunes, but it probably is not. iTunes is just affected by a conflict with another program (possibly).
    Do you have a spy sweeper/virus scanner/etc. that periodically scans your PC memory? If so, then that is what may be interacting with iTunes.
    You should list the iTunes Folders as part of the exclusions within your Virus Scanners, and other Security software.
    BTW: I have a Library with over 13,000 song references. I do not see the same CPU spikes when playing music. It's not the size of the database - not at your current level.

  • High CPU Problems With Screensavers and Flash Player - FYI

    Upgraded my 1.42 Ghz PPC MacMini (1 GB RAM) to Leopard, fresh install and suffered high CPU problems as outlined in various other threads.
    Fixed major 100% cpu and 100% FAN issue by removing The Weather Channel Screensaver - so have a look at your console system info and see if a 3rd Party screensaver is causing a problem, or if no 3rd party screensaver, try using a simply screensaver like Forest.
    Safari/Netscape/Firefox also were using high CPU when a webpage was using Flash, I removed Flash Player 9 (latest version) and cpu load decreased dramatically.
    Go here for uninstall DMG
    http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157
    Hope this helps someone else until there are fixes.

    Just wanted to clarify that the Flash and Screensaver problem is still ongoing even after the latest QT updates as of Nov 07.
    The Flash problems is with Flash images/code that use moving graphics/user input, such as those adverts you see where you push a button to punch Paris Hilton.
    I think the overall problem is with the way QT/Core Image/Core Animation is different in Leopard compared to Tiger. As have now often witnessed iTunes just displaying the Cover Flow image area and nothing else (everything else in the application area is white) when going between applications, clicking on the iTunes icon in the dock refreshes the image okay.

  • Screen sharing using high CPU!

    Hi
    I have a strange issue on my Mac Mini.
    I run it without a monitor as it is primarily an iTunes server but mount it via Screen sharing to my iMac.
    Just FYI I am also running iStat Menu's so can easily see CPU performance etc.
    If no activity on the Mac Mini everything is fine and CPU utilisation is quite low, apart from some BOINC apps that are running.
    However, if there has been, not currently but has been some screen activity on teh Mac Mini then CPU is running about 60% and this is almost totally Screen Sharing!
    If I 'touch' the iStat CPU menu, this high CPU falls away back to normal levels.
    Something really weird is happening and i do not know what it is.
    Any ideas?
    Robin

    The screensharing CPU issue is still there in Mac OS 10.8.2 :-(
    (i have the problem on my mid-2011 mac-mini server)
    top sorted by CPU shows clearly two "screensharing"/"Screensharing" processes eating each about 45% CPU

  • Safari 3.03 for Mac has high CPU usage usually above 70%

    I look at the Activity Monitor and it shows Safari using a lot of CPU % around 70 % and some times near 100%

    This High CPU usage is also a problem that has just started recently on my G4/667/1.5Gig Ram with a "Giga" 1.33GHz upgrade running System 10.4.10. My machine has been wonderful for years with this processor. I'm running Safari 2.0.4. When i did the last upgrades to my software I started having some real bad behavior from my mac. High CPU usage in safari (80-98%) for 3-5 minutes then normal like now I'm at 6-10% (Normal)as I type this in Safari. Safari is crashing when I try to open the Apple in store training site! Mail was crashing on my wife's login not mine though. Throwing out her mail Prefs fixed that. The Upgrades that seem to trigger this are Java for Mac OS 10.4 Release 6, Quick Time 7.3.1, GarageBand 4.1.1, iPhoto Update, iTunes 7.5. It sure feels like that last set of upgrades has made a mess of my mac. I suspect the Java update. How do I fix this mess???? [email protected]

  • Syslogd makes high CPU Load and standby mode doesn´t work.

    After updating to Leopard I see high CPU Load caused by syslogd daemon(40%-80%) and my MacBook has problems with standby mode. After stopping the white LED lights and CPU fan speeds up. Is there any chance to fix these problems?

    OK.. here's where I'm at with troubleshooting this. As I said before, for ME it occurred simultaneous to a low or out of memory situation. I don't know if syslogd was using my the ram, or if the low ram was a symptom of an issue that syslogd was getting caught up in reporting... but the system log file had tens of THOUSANDS of out of memory errors listed. Almost all were from dashboard.
    So... I've done the following. In dashboard I closed ALL open widgets. I disabled spaces (since in another thread someone indicated it used a lot of memory). I ran Leopard Cache Cleaner and used it to perform maintenances, run the os scripts and rebuild caches and so on. Rebooted.
    Now its working fine! Since then its been over 24 hrs and I STILL have over 300megs of ram reported free on a 1 gig system. I've used everything else like normal (safari, mail, ichat, itunes, etc..). Where the problem used to happen after a couple of hours after a reboot every time, now it seems normal. No out of mem, and syslogd is running normally (apparently).
    I will run a few apps that I havent run in a while and see if those create an issue. If not, later today I will enable spaces and see how that does after a few hours. Finally I'll add in the dashboard widgets one at a time to see if the issue lies there. I'll report back here if I discover anything.

  • 3G High CPU utilization when waking

    Recently gave my iPhone 3G to my wife, restored it to a new phone, then synced it with her information, music, applications, etc. She previously had used an iPod touch, and basically was trying to upgrade her to an iPhone.
    The phone worked fine when I had it. I only had a short time with this specific phone as it was replaced under Apple Care about a week and a half before turning it over.
    Now it pretty consistently is unresponsive when trying to wake it. By bringing up the System Activity Monitor App as soon as possible after powering it up, and leaving that app active when putting it to sleep I can see that the CPU gets slammed for a while during initial startup and has a significant period of very high CPU when waking. At this point I believe the cause of the unresponsive behavior is that the CPU is maxed out doing something.
    I've compared the running processes to an iPhone 3Gs and they were identical except the 3G was missing the MobileMusicPlaye until I brought up the iPod on that phone.
    There are 2 things about the initial setup of this phone for my wife that are causing me some concern;
    1) When first connected to iTunes after the Factory Reset I was prompted to restore an older backup than the iPod Touch one I took right before the swap. I didn't realize it at the time and accepted that restore.
    2) I was prompted to upgrade and followed through with an upgrade to 3.1.2 after the Factory Reset even though the phone was at 3.1.2 before the swap.
    At this point I'm thinking about doing another Factory reset and set it up by sync only (no restore) but not looking forward to the time investment that will take.
    Any ideas on where the high CPU utilization is coming from on wake? Is that a reasonable theory that the high CPU is causing it to be unresponsive when first woken up.
    Any other insight from others that have been through this?

    I ended up restoring the 3G phone to Factory settings and then sync'ing the desired information / applications onto it (did not restore the previous backup). The behavior is improved but this phone does seem to get bogged down when waking (observing high CPU utilization when monitoring with System Activity Monitor and experiencing sluggish / jerky response to user actions with no applications or just Mail running). The periods of non-responsiveness are not as long or as severe at this point, but still noticeable.
    I'm at a loss since under the conditions I'm observing this there is nothing but Apple software running on the device (behavior is present with or without SAM showing me the CPU utilization). I'm a little suspicious that it might have something to do with re-establishing the WiFi connection, but it seems to continue for a bit after the WiFi icon appears in the status bar.
    I'm probably going to make a genius appointment to see if they have any other ideas.
