10.5.0.142 upgrade now itunes services using 100% cpu

My itunes has updated a couple of days back and since then I've been unable to synch my iphone 4 AND more importantly my laptop is running really slow. I checked and AppleMobileDeviceService.exe is utilising 50% of cpu. Even without itunes open! If I launch Itunes then I'm up to 100% and my laptop becomes unuseable. I've tried reinstalling to previous versions of itunes but because the libarry has been upgraded to 10.5 previous versions of Itunes wont work with my library.
I can terminate the cpu hungry process and gain control of my laptop but now I can't synch my iphone and working with itunes is very slow.
Clearly something's not right and it all appears to have happened as a result of the last update.
Interestingly, when I retroinstalled previous versions of Itunes AppleMobileDeviceService.exe did not appear to be present or if it was it was using so little resource it wasn't showing on the listings of services that were using resource.
My laptop is Windows 7 SP1 with latest updates applied.
Similar problems seem to be plaguing alot of users since the end of September???
This looks like and Apple issue?
Anyone had this as well and resolved it?

Fixed. Downgraded to 10.4.0.8 with clean 10.4.0.8 library.
Lost my music content which I'm happy to rip again but many wouldn't.
Iphone synching perfectly.
CPU utilisation with iTunes and applemobiledeviceservice.exe running below 10%
BINGO!
So there we have it, 10.4.0.8 is perfectly fit for purpose.
So what conclusions do we draw from this exercise relating to the 10.5 upgrade to iTunes and the over 11,000 views of similar problems on this forum?

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
MR Tech Toolkit 6.0.4
repagination 2006.4.5.1
Save Complete 1.0.1
Session Manager 0.6.8.3
Tab Mix Plus 0.3.8.4
Unhide Passwords 1.2.5.1
User Agent Switcher 0.7.2
Thanks for any help or suggestions.

Itunes 8 using 100% CPU on one core.

Hi Guys,
Since today Itunes seems to be using up 100% CPU on one of the two cores. This happens shortly after i started it - for example when i play a song.
After a few minutes it will be reactive again and then i can choose another song - after which it will hang again. It also hangs when changing for example from Films to Music. I have the idea that it happens when i click the Music library - but am not sure. I disabled AV for the itunes library folder - but that didnt change anything. This has been working fine until today. I even uninstalled and re-installed version 8. The only thing that might be related is that when i upgraded to ver. 8 i used the update function in itunes - which didnt work as well - left me with some unusable shortcuts etc. But the app itself was working.
OS is vista.
Just saw that this is for the store only - Moderators please move if possible.

When I first boot-up, I get 100% CPU on one of the cores. htop reveals that it's the X session that's running away (?) Rebooting seems to take care of it--although I don't understand why yet...
Anyone experiencing this--or have any suggestions on what I could look at to see what the problem might be?
Thanks in advance...
I had this problem with mount. In fact asking the system for shutdown would set a live lock on a mount process taking one core.

Win8 Antimalware Service use 100% cpu in idle

When I am doing nothing on my Yoga then Antimalware Service is started and my Yoga is soooo loud with fans and sooo hot. Can anybody know how to disable this Antimalware Service? I know that I can disable Windows Defender. But I want realtime scanning when I am downloading something. I just dont what scanning hdd when I am in idle. In Win7 you can disable scanning in idle and only have realtime scanning. I Win8 this options is not available. Anybody solved this problem?
Solved!
Go to Solution.

Hi szy,
There isn't a setting in Defender to use on-demand scanning, but there is a way to turn automatic scanning off though.
The scan runs as part of a scheduled task:
1. Open up Task Schedule (search Schedule Tasks and it will be under settings)
2. Double-click to open up the Task Scheduler Library on the left side pane, its located under Microsoft -> Windows Defender.
The one you want is called MP Scheduled Scan, if you click it on the bottom of the right side bar you can disable it.

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!!!!!

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".

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.

Microsoft.Exchange.AddressBook.Service.exe 100% CPU Usage

Hi,
We have an exchange server 2010 and the Microsoft.Exchange.AddressBook.Service.exe used 100% CPU Usage suddenly. However, after rebooting the server, the CPU Usage of the above .exe is back to normal. Client cannot connect to the exchange server during
the high CPU Usage of the above .exe.
Any ideas for the above problems? Thank You.

Hi
Microsoft.Exchange.AddressBook.Service.exe is related to OAB function.
Maybe mobile or client fails to download will cause this problem.
What was the fix for this?

Upgraded; now itunes won't work

i recently upgraded my computer to Mac OS X. when i went to open up iTunes, an error box popped up that said "The file 'iTunes Library' cannot be read because it was created by a newer version of iTunes." what should i do?

I had the same problem - upgraded to ITunes 6 and suddenly the application stopped working. I also tried uninstalling, and reinstalling old versions as well as v6. I called Apple, and they had me set up a test user to see if it was a systemwide failure (if it was just the upgraded Itunes on my main user that was affected, then the basic Itunes available for the test user should be fine). But it was systemwide, so I had to back up all data and reinstall the operating system, then run a software update to get my system back up to speed. After the software update, I ran a disc permissions repair to the drive (available under "Applications", then "Utilities", then "Disk Utility"), which is recommended after each install of software or software updates (I didn't know this, being somewhat new to Mac). But now Itunes 6 works fine, with no problems! Hope this helps.

I'm having the same problem! At first after installing leopard it wouldn't let me access the apple site! Called support they had me make up another user and access it from there and it worked. Also closed all my start up items. Now it won't let me access Itunes store even though I can access the web for everything else! Any clues??

ITunes store using 100% of CPU

Since upgrading to iTunes 11.0.4, performance of the iTunes store has been horribly slow, taking 5 seconds to register a keystroke and using 100% or more of the CPU. Any idea what's up?

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 n 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 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.

System service using all CPU w/XP SP1

I have a K7N420Pro and after I install XP SP1 the system service uses all available CPU cycles. If I check the task manager my CPU usage is at 100%!! has anybody else seen this?
By the way, It is the system service not the system idle process.
System specs:
K7N420Pro
Athlon XP 1900
1.5 GB Ram (3x 512 MB)
2.6 BIOS

I pulled EVERYTHING off the MB. Floppy, CD/DVD drives all the memory except one stick, I even disconnected the USB and diagnostic leds. That didn't work. Then I realized that the small sound card addon wasn't actually part of the MB even though it came with it. I powered down and pulled the CNR Sound MAX card and when I rebooted it found some additional sound hardware and the system service was back to no CPU usage. I then shut down and readded the CNR card and when I powered on the system it was still fine. I now have to reconnect all the rest of the stuff I removed and make sure it is still fine but it looks good so far.
Well, It's not fine. When I rebooted the problem was back. I will now pull everything off again and then add it back one piece at a time. :(
OK
Now I finally know what the problem is.
I had both of the additional USB connections filled. One from the diagnostic thing and the other from the front of my case. Well I guess that the cables from my case are bad since when they are connected my problem is there but it goes away when I remove them. I can definitely live with just 4 USB ports. I only have 3 USB devices right now and if I ever get more I can just add a USB hub.
