100% CPU ussage at all times

I have been experiencing a strange problem with itunes (7.2) for the last week which I have never encountered before.
It all started when I doubled clicked on a mpg hd mpg file (1920 x 1080) by accident rather than right clicking and hitting play with windows media player. Ituens opened up but did not add this file to the library because it's incompatible. However, I tunes at that time stared using 100% cpu usage on my system and lagging to death.
Now every time I open Itunes it takes 2 minutes to appear after opening it, then another minute to respond before it actually does anything if you click on anything such as library, store or the file menues. Once you click on any of those, or any link in the store once again you have to wait 2 minutes for itunes to actually go there and start responding again. Playing of songs or videos is extreamly choppy.
To fix this problem I have tried rebooting, reinstalling itunes, and trying ot see if there is anything visible in my library that could cause the problem when loading (which there is not)
This problem has been going on for a week now, and itunes uses 100% cpu usage at all times while open, it never slips to 99%.
This is happening on my laptop with Windows Vista x64 Ultimate, AMD Athlon x2 4800+ and 2GB of ram.
Does anyone know what might be going on here or how I could fix this rather annoying problem so I can use ituens normaly again.
I'm just glade my processor has more than one core, so my system doesn't bog down and stop. (Itunes shows 50% total system cpu ussage at all times or 100% single core)

So, are you on XP Pro or Vista Ultimate? Kinda confused.
I'm hedging my bets on the file being corrupted. You say you don't get these problems when running the file from WMP?
BTW, have you restarted your PC since the aforementioned 100% CPU usage?
If you haven't, you could try opening up task manager (ctrlshiftesc) and killing the iTuneshelper process along with iTunes. I'd do the kill process tree thing. Do check if there's anything else using up memory.
If all else fails, restart. If you've done that already, then we can start looking at other options.

Firefox hangs with 100% CPU at (obviously) random times

Several times a day, my Firefox suddenly responds pretty slow and within seconds it no longer responds at all. The CPU usage of firefox.exe goes to 100% and the whole browser seems to be frozen. In some cases, the memory consumption in the TaskManager also increases slowly (about 8KB/s), but not always. However, after 30-60s the problem suddenly vanishes and everything is fine again.
An interesting detail: Firefox uses a lot of memory; I am not sure whether this is normal. Currently, I only have this tab opened, but it still uses 166MB! The peak memory usage even says 351MB, although I did not have more than 8 or 10 tabs open at the same time (no YouTube or similar memory intensive sites).
The problem might be caused by an update to an extension; at least I remember that there was an update shortly before the problem first appeared. However, I do not remember which extension it was. I have disabled almost every extension (only TabMixPlus, Download Statusbar, and TinyMenu are still active), and the problem is still there. It is hard to find the reason because the problem only happens three of four times a day and at random times, so it is hard to reproduce.
Some questions:
1) Anyone has got an idea what might cause these problems?
2) Is there a way to see which extensions have been updated recently?
3) Is there a way to see which extension uses how much of the CPU?
Thanks in advance!
gehho.
== This happened ==
A few times a week
== about two weeks ago (maybe after an add-on update, not sure which)

Just some additional info:
I just had the problem again, and it even occurred when I did not have any tab open! I did not even use Firefox, but just wanted to start to use it, but it did not respond. There was _nothing_ open, and when I checked the TaskManager, the memory consumption was up to 300 MB, and the CPU was again at 100%. After the CPU was down to 0% again, the memory slowly decreased as well. First, to ~260, then to ~200, now to ~170 MB. Maybe it will decrease even further...

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.

Softwareupdated uses 100% CPU constantly on Yosemite

Does anyone else have an issue with Yosemite where softwareupdated uses a full CPU core at all times? Ever since the upgrade to Yosemite, the softwareupdated process always consumes around 100% CPU. I noticed this the other day when I closed my laptop at the end of the day and the area above the left side of the keyboard was very warm. Looking at Activity Monitor, the softwareupdated process was running at full blast.
Ever since then softwareupdated runs constantly, no matter how many times that I kill it. It causes the App Store to hang when I click the Updates tab. The only way to get the updates tab to show up is to Force Quit the softwareupdated process completely.

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".

This new version of FireFox is making me nutz! It is SUCKING 100% CPU time almost constantly. I could just pull my hair out. I wpdated once a month or so ag

I tried to add this in the topic already open but it kept sending me through the unending rabbit holes!
My question is: How do I figure out what release I was on, get rid of this one and got back to a functional firefox that moves in realtime. I already did all the reset and etc.... I just want to go back to the speed I had. This halting , hanging up misery of a browzer is Sad. I have had firefox for years and always recommended it ..... BUT NOT ANY MORE. I agree with the other poster ... there should be a rollback feature. Peoples time has value and right now FireFox is sucking the value down a rabbit hole.
See Below Comment Feedback submitted before I finally got here:

I came here to fix it a couple of dayz ago and did the reset firefox and now it IS RUNNING SO POORLY AND SLOW I AM ABOUT TO KILL IT OFF MY MACHINE!!! Yes that is me yelling - and it happened in SSSSSSSSSSSSS LLLLLLLLL OOOOOOOO WWWWWWWWWW Motion. I have run all the security scans and cleanups ---this needs a fix ASAP!!! PS: The hang ups and slowness is EVERYWHERE I go. I only get speed doing programs not connected to ON LINE.

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

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.

FF 20 and Flas 11 = 100% CPU - Opera, IE8, Chrome are all OK. FIX IT!

I am absolutely sick and tired of hearing excuses about why FF is not to be blamed when it chews 100% CPU with the Adobe Flash plugin.
I have done all the dancing around I am willing to endure. I have even downgraded to FF18 and FF19. No friggin setting works. Nothing. IT IS IN THE CODE!! FIX IT!!!
It is simply NOT acceptable that ANY other browser in the known universe works OK with Flash BUT FF.
It is time that devs acknowledge this and do something about it instead of scratching their butts!
PLEASE do not get me more links to troubleshooting pages, either from Windows, Adobe or FF.
I'll repeat: IT IS IN THE FRIGGIN CODE. FIX IT!!!

Also IE uses a Active version of Flash and Chrome comes with its own Flash though it can use Adobe version if pepper version is disabled.
Adobe has been making a buggy Plugin for Windows ever since they came out with the Flash 11.3 version.

Interesting little app that gives 100% CPU time to your app of choice.

Hi All,
I saw this cool little app that basically shuts down all other non essential processes and gives 100% CPU time to the app of choice. It is called Freeze Frame. Thought it might be worth a look, with all the overloads and all ..... PS - I am not affiliated with this company whatsoever.

I was hoping to get some pointers 'in abstracto' as to what generally may lead to such behavior (i.e not utilizing 100%). Unfortunately, there are about a snotzillion things that could cause the situation you describe. As already pointed out, all we can offer are random guesses, and that's not a productive use of anybody's time.
Perhaps my question was indeed to broad.Yup.
I'll get back to it with a more concrete simplified code example if I can . Excellent.

CPU goes to 100% state svchost takes all resources on Qosmio F10

CPU goes to 100% state svchost takes all resources. Norton does not find any illegal software. Have tried to list the processes (run... etc.). I get a long list, don't know what to do about it. Does anybody out there have some help?

Hello,
if you have your note for a year or more and did not take it for an internal heatsink clean and essentials parts, yet.
One possible problem here is: Heatsink blocked with dust (CPU goes to 100% state svchost takes all resources)
90% of the high temperatures problems, unexpected shutdowns, 100%CPU all the time without running background processes, very hot keyboard area, freezing programs, are caused by the heatsink blocked with dust.
The normal temperature for the processor is between 55C and 79C. For the motherboard is around 55C~60C. When the heatsink is blocked those temperatures can reach 99C (processor) and around 80C (motherboard). Measure in Celsius degrees.
You can check it out how "hot" your Qosmio is.
Download the Everest ultimate 2006 edition V 3.50.761, look for it with Google search.
Run it and see the temperatures for CPU, Processor and motherboard on your Qosmio:
See:
http://www.rabayjr.com/vista/qosmioeverest.jpg
Run the System stability test (find it under tools menu) for 10 minutes aprox.
Watch the temperatures at taskar. If it reachs more than 92C for the processor on stress mode, its time to clean the heatsink and all essential parts of your Qosmio. Attempt to the processor fan RPM, too, if they run fast and noisy, you really must perform a clean.
But it depends on the ambient environment, for a 30C summer day the processor temperature almost get the 90C. this is normal in stress mode. And the fans run without noise. Slow RPM mode.
All measured in Celsius degrees, for Farenheith please convert it.

Zenity takes 100% CPU Time

When I run as root or normal User
zenity --notification --text="test"
The zenity process takes 100% Cpu time
System:
Arch 32bit gnome 2.22

I GOT IT... I think.
zenity --notification actually calls libnotify! I was trying out a script and suddenly realized something, because by chance dbus decided to take a break. Take a look at these two code fragments.
$ zenity --info --text "hello"
$ _
$ zenity --notification --text "hello"
libnotify-Message: Unable to get session bus: Failed to connect to socket /tmp/dbus-jmMdFXbznS: Connection refused
<hang>
<100% CPU usage>
I've figured out why: it's basic socket programming gone wrong. The notification part of zenity calls libnotify, tries to connect to libnotify's socket, and fails, using 100% CPU waiting for the connection to... end a stream that never started.
A possible solution is to just use notify-send.

Cpu maxed out at all times..

I'm very concerned about my Gnome install. I updated for the first time in a while, and rebooted - just to see how things were. I started X (no issues), and Gnome loaded quickly. The problem is that my CPU is now maxed out for no reason, and it never drops between the 95% mark. Gnome system monitor is reporting 100% usage, but when I check my processes with it, I can't find the culprit. htop shows that X is using 94-100% CPU - something that I find hard to believe.
Here is htop output;

Genius updating taking 100%+ CPU time and error 13011

Does anyone else have the issue of iTunes updating Genius causing their CPU usage to max out run the cooling fan at full speed?
Im getting an average of 100%+ CPU usage while its updating or compiling or whatever its doing and Macbook cooks whiles its doing so.
Activity Monitor is reporting ridiculously high CPU usage. How do you even get 108% CPU usage?? Can someone explain that for me?
Im also getting the message 'unable to save library' with error 13011 at the end of Genius updating (the Genius update progress bar is full).
Can anyone give me some pointers as to what I can do to check why i'm getting these issues or if there is resolution?
Killing the Genius data gathering solves the CPU usage issue straight away but I'm sure it wasnt this bad before Snow Leopard.

Audio Bin - Select unused - Delete - Hangs on 100% CPU for long time

Hi
I am running Logic Studio 9.0.2 on OS X 10.5.8 on a Mac Pro. Logic was upgraded from version 7.
In Audio Bin and "Select Unused" and then "Delete", the application might hang on 100% CPU for hours on large projects.
Anyone with an idea of what the problem might be? This was not a problem i Logic Pro 7.
Thanks!

I have this same problem, though I'm on 10.5.7. I was hoping maybe updating the OS would help but apparently not. I also get very slow file-selection windows sometimes, like when I go to bounce a file. Navigating to a specific folder is painfully slow. Would like to hear if any Snow Leopard users are experiencing this.
