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:

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".

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.

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.

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

Thanks for any help or suggestions.

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 :
7. Profit!

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!!!!!

Discoveryd process uses 100% CPU - Safari Can't find the server

Hello
Since upgrading to Yosemite, I lose connection to the internet 2 or 3 times a day. (Outlook goes offline at the same time)
This is with a wired connection. (Wi-Fi is turned off)
Safari gives me the "Safari Can't Find the Server" message.
Restarting the computer solves the issue temporarily.
While I'm unable to connect to the internet, Activity Monitor shows a process named "discoveryd" that uses 100% CPU.
Force quitting this process gives me back access to the internet instantly. Unfortunately, I suffered a kernel panic (auto restart) a few minutes after force quitting discoveryd. I'm not 100% sure those 2 are related but it would be an odd coincidence as I never experienced had a single kernel on that system. Haven't tried force quitting that process since.
I'm using this iMac in a work environment. (Connected to a windows file server and exchange)
This issue has been happening 2-3 times a day since the day I upgraded to Yosemite.
Any pointers on what could fix this issue ?
Thanks

Apple Mail client (version 8.0) using 100%+ CPU upon using mail drop (13" R-MBP running Yosemite 10.10)

Hello Support Community,
I am having quite the interesting issue. I have read plenty of reports where users' Apple Mail app is using 100% of CPU. This did not start for me until I went to go use the new mail drop feature in Yosemite. I am running Yosemite (10.10) on my 13" Retina - MacBook Pro (flash storage, 8GB RAM, 2.4 dual-core Intel i5) and my Apple mail is version 8.0. I have tried 3 different mail services (2 gmail accounts and iCloud), all result in the same issue. I have also done a complete erase of the hard disk and a brand new install of Yosemite, the issue persists.
As previously stated my mail app is using 100% upon, and only while, using the mail drop feature. If I force quit the mail app and allow it a minute, the mail app returns to using less than 1% of the CPU and the app and entire system resume normal function. Upon attempting to resend the same message that is placed in my outbox the CPU usage jumps to 50-80%. After a few seconds, the CPU usage will sometimes jump higher than 100%, ranging from 130% - 199%. All of these observations were made using Activity Monitor. Of course you can see my frustration, an app using this much CPU stops every process my Mac is doing (using safari, messages, iTunes etc.) - the whole computer locks up. Even force quitting is a difficult process to attempt.
Does anyone have a fix for this? I am at a loss and have no idea what to do. I am a pretty tech savvy guy and have tried everything that I would've thought would fix this. Is there anyway this could be a hardware issue? I don't think so but... all possibilities need to be taken into consideration, even though that one seems outlandish. Upon creating a new user account with a separate user library (but same system library) I figured the OS was the problem. I can't narrow it down to being a specific mail provider, and it can't be my OS since I have now erased and reinstalled 10.10 twice. Thank you!

I have this same issue. It has been driving me insane, Mac Mail uses 100% CPU most of the time I use it, after every time I open the machine, or after a sleep or even mostly after a screen saver has locked me out. It normally settles down after 5-15 minutes, but then happens every time again. It is killing my battery.

10.5.2 Uses 100% CPU for about 10 mins

Everything was fine on 10.5.1 but 10.5.2 on Windows 7 32bit seems to use 100% CPU (iTunes.exe) for about 10 mins before settling down. I was just about to post 100% CPU when I saw it was back to normal so I closed and reopened it and the same thing has happened. PC has been restarted since it was installed.
Any idea what is causing this? Can I downgrade - if so, how?
PS: it's actually using 100% of one core.

Check out this Apple article -> iTunes 10.5 for Windows: May see performance issues and blank iTunes Store
If you have one of the LSPs mentioned, you may have to do a winsock reset or remove the conflicting software.

Finder and loginwindow use 100% cpu with 10.6.8

I recently installed the patch to OS X 10.6.8 and now the finder is very unstable and uses 100% cpu and the loginwindow uses 100% cpu also. Yes I have Parallels 6 on this machine but I already "un-checked" the "show windows applications in doc" option which is the recommended solution. However, this did not fix the problem. I do not know how to determine what actual process is causing this finder / loginwindow issue. I very much appreciate if anyone has suggestion how to fix this problem.
This is on a mid-2011 MacBookPro.
thank you.

TBauer, I had the same problem with 10.6.8 using 100% of the CPU with Parallels 6 installed. The following steps solved this problem for me:
0. Take a screen shot of your Dock if you wish to remember it as currently set
1. Launch Activity Monitor and click on the CPU column so you can see Dock using the CPU
2. Move ///Users/ ... /Library/Preferences/com.apple.dock.plist to the trash
3. Click on Dock and click on Quit Process to stop the Dock
OS X will then rebuild the default Dock
4. Put the items back in the Dock that you want
That solved the problem for me yesterday morning. I've launched Parallels 6 several times now and moved the machine from my work network to home and the 100% CPU problem hasn't returned.
Hope that works for you, too!
I don't think using the combo updater will solve the problem. The problem appears to be a .plist that is generated with OS X 10.6.7 and earlier that contains icons of a larger than Apple documented size causes the CPU looping. Rebuilding the dock.plist under OS X 10.6.8 appears to solve the problem.
Parallels has issued a knowledge bulletin saying they are looking into the problem. On their web site they have another approach involving moving the offending icon out of the dock to solve the problem. I like my solution better but theirs works, too.

New DVD writer on Satellite M40-193 uses 100% CPU

Hello anyone,
recently I have replaced my DVD-writer with a new one. My laptop is a Satellite M40-193 (PSM40E-06M026IT) and the original drive is a Mat****a UJ-831B. I have replaced it with a Sony-Nec Optiarc AD-7633A because I like the slot-in feature and the Labelflash feature.
Unfortunately it makes me a problem. It will use 100% CPU every time I use it. I cannot figure out the problem. Is there anyone who can help me? It is a software problem or hardware?
Thank you.

After six days this is the only help I can get on this forum: "...this optical disc drive is compatible with your notebook model?".
The ATA communication bus is a standard.
The exsistence of a compatibility list does not means that ONLY those drives present in the list can work with the relative notebook.
Those drives are the ones tested and the ones that Toshiba says: "this drive surelly work" but not says "this is the only drive that work".
In fact I have RESOLVED the question with a little software I have found on another forum and now my drive works perfectly and I have a newer and more featured drive than those in the list.
Thank you Mike

Oracle uses 100% CPU

Hi,
I have installed Oracle 10g R2 on 64bit linux. It was working fine, until last week. I got alert that oracle uses 100% CPU.

When I log in to EM, I can see section
Host CPU
It is 100%.
I have only instance named "parama". and it uses 1% CPU ant the picture shows that 99% CPU is used By Other.
What is Other? Why does it use that much CPU?
I had another oracle instance few months ago, but I is not used now (it is not even started).
How do I restore normal system performance?
Can I kill these processes?

Hello,
I have a similar problem. I see 2 perl processes related to Oracle that are taking up 99% of 2 cpus. These 2 perl processes have been running for days and keeping the load average high (above 2) on a mostly idle system.
The 2 perl processes are running:
/oracle/app/product/10.2.0/db_1/perl/bin/perl /oracle/app/product/10.2.0/db_1/sysman/admin/scripts/db/dbarchfull.pl
and
/oracle/app/product/10.2.0/db_1/perl/bin/perl /oracle/app/product/10.2.0/db_1/sysman/admin/scripts/db/dbresp.pl
Has anyone seen this problem? Can I kill the perl processes?

Start x11vnc -- X uses 100% cpu load

Hi.
I switched to arch64 and today I first used x11vnc and it is extremly slow. First I thought about the proxied connection but after looking into top I found X is using 100% cpu load. With arch32 everything worked as normal. Don't know whats the problem - any advices?
Regard, Andreas

Hmmm, I switched from official nvidia driver to xf86-video-nv and now works much better. I'll try it again with nvidia but not today...

All programs using 100% CPU, freezing, crashing, -10810, -600, and -1712 errors

Okay, so. I have a Macbook Pro from December 2012, a little over a year old.
Version 10.9.1, running Mavericks
Processor 2.4 GHz Intel Core i7
Memory 8 GB
Startup Disk - Macintosh HD
I can send more info if I need to. I'm a graphic designer using Photoshop, Illustrator, and InDesign usually simultaneously, as well as Spotify, Messages, Sparrow (mail), Stickies, Tweetdeck, and Evernote. I also use a wireless mouse, drawing tablet, and second screen. This has never been a problem (I mean, my old computer had 4 GB memory and handled these programs just fine, except for Final Cut Pro 7) up until recently.
For the last two months, my computer has been seriously out of whack.
I'm constantly having to refresh finder
Every time I open Google Chrome, all of my extentions crash immediately and any website I try to go to is extremely sluggish (but Safari works)
The dock freezes
Constant error messages: 1712, 10810, 600
Audio fails randomly
Overall, the problem seems to be that I can't do more than one thing at a time -- I can't take a screenshot if more than two programs are open, I can't open DMG files, I can't open Spotify if any Creative Suite program is open. I've been watching the activity monitor, and it seems like each program is trying to use 100% CPU, which doesn't seem right. I have to close every program to work in Photoshop, which makes me miss calls and emails.
I've tried restarting in safe mode, verifiyng the disk and repairing permissions, I used time capsule to restore to a time before it was happening, and restored my user profile in Chrome. I'm at my complete wit's end trying to figure this out! I feel like my next step is to just reinstall my OS completely, but that would be a major setback for getting my work done, and I'm not even sure that would work.
I've looked on other forums and it seems like the Mail app typically causes problems, but I don't even use it, I use Sparrow.
PLEASE PLEASE PLEASE HELP

Launch error -10810 in Mavericks
I have the same issue since a couple of days. Nothing that I found in the community (rebuilding launch info using Onyx or manually deleting the apple.com-launch prefs) has helped me so far. Only some apps are affected (PasswordWallet 4.7.4 among them).
I can launch it once and it will run fine as long as it’s open. Next time it refuses to open displaying the error -10810 message instead. I trash the app and use a fresh one off the vendor’s dmg file I downloaded and the sequence repeats.
MacPro 2.8 QuadCore Intel Xeon, 16 Gig RAM, Samsung SSD 840 PRO Series HD plus 3 more regular 3,5“ HDs, Mavericks 10.9.3

Itunes uses 100% cpu
