IMac CPU maxed out on nothing??

Can someone explain this to me?
My iMac's CPU has been pegged for pretty much two days now and I have no idea why???

Nevermind...Just found it. Curiuos by F@H is running at full bore in the background but not showing in the panel.

Macbook Air 2011 CPU Maxes Out then Overheats and Shuts Down...

I've been having this problem for a while now but have learned to deal with it with SMC Fan Control to basically keep my fans maxed out at all times. This is obviously not ideal.
The problem is that at any given time some small, random task in activity monitor shows CPU usage that is very high, often at least 50% CPU and other times as high as 120% It has happened with the tasks like dock, safari web content and virtually any other task you can imagine.
For example, I just tried emptying my recycling bin and it hung half way through then my computer shut down. What is going on here?
Details:
- Macbook Air mid-2011 running Mavericks
- Never have more than one app open at any given time, usually just Safari with about 5 tabs, max
- 3rd party applications running in background include Dropbox, Copy, Backblaze, Flux, Sophos anti virus, Jumpcut, Caffeine and that's it
If I'm doing something like a Time Machine backup, I have to disable Wifi, max out the fans and only then will the Macbook Air remain cool enough to complete the backup, otherwise the Time Machine process maxes out the CPU, overheats and shuts down. This happens with virtually everything now.
How can I start trouble shooting this problem? I've run the hardware and system repair checks with no results, done an SMC reset, etc.
This really seems like a software issue more than anything, like something related to the way tasks/processes are handled...any ideas anyone? This is such an annoying problem!

Do the problems also occur in "Safe Mode"?
Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
You must disable FileVault before you can start your Mac in Safe Mode.
Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
To end Safe Mode restart your Mac normally. Shutdown will take longer as well.

Updated to 3.1 and CPU maxed out causing click and pops

I upgraded to Mainstage 3.1 and now the CPU meter is maxed out when I change presets and also MainStage runs at 100 % causing clicks and breaks in the sound when using a vst plugin S-Gear by Scuffham. Earlier versions work fin at 20% to 50% CPU. I can't go back to version 3.0.4.
Help!

In preferences, try raising the I/O Buffer size in preferences. Then lower the driver latency setting. It seemed to help CPU load.

CPU maxing out with Google Image search, some other websites

When I try to use Google Image search or load SBNation website articles, Firefox's CPU usage maxes out and it becomes unresponsive for a good 10 seconds before it has loaded everything. This is a new problem that has popped up within the last few weeks.
I've tried disabling all addons and plugins, removing cookies, clearing cache, downgrading from the beta version to 23 and none seem to make any difference.

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

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;

Cpu maxing out!!!!

my processors are maxing out. i have portal 30983 and db 8174...everytime i make a page request the processor spikes through the roof. there are only 30 or so users hitting the portal so the workload shouldn't be that bad.
the processors are dual 550's on one box and my prod box is dual 800's
any help would be greatly appreciated

Read through the steps of "Troubleshooting Issues in Oracle9iAS Portal Architecture & Performance" at the above link on PortalCenter. There are a number of things in that document that check the validity of the cache configuration (etc) that should be followed to ensure that the basic configuration is working correctly.

(SOLVED) CPU maxes out without warning.

Successfully installed Arch on HPdv5000 laptop. Using LXDM/LXDE. Solved wlan configuration.
Current problem is connecting to LAN. Followed Samba procedure prescribed by Arch, (as best I could). Edited smb.config to my existing workgroup name.
In pcmanfm I would click go-network drives which would then freeze pcmanfm, Next, the cpu monitor would go from flatline to top of scale, fan would start and not stop. My only escape was reboot. I then entered smb in pcmanfm address bar and it auto filled with my workgroup name. attempting to open the workgroup directory would result in failed to mount windows share.
Home network is combination of Win7 laptop, WinXP desktop, Ubuntu 10.10 server, Lubuntu desktop and the HPdv5k laptop.
Lastly, the cpu behavior is occurring without initiating the previous triggers.
Can someone help?

Another idea: Forced shutdown due to overheating. Have you recently cleaned the system fan or have taken a look at the CPU/GPU temps[1]?
The Nvidia 140M alone is producing a lot of heat. And isn't the Intel C2D T9300 running even hotter than e.g. a T7500?
[1] I'm using tpfancontrol to read out the temps of my T61. But remember to set the cooling mode to BIOS. (Or manual and speed = 7)

Why is CPU maxing out 100% when burning dvd?

I bought premiere elements 13 yesterday and got my dvd ready to go. I started burning it today and it's been over an hour and still processing, it may have taken 1.5 hours total. Trying to run photoshop at the same time was making photoshop very slow so I checked resources I saw premiere was using 99% of my cpu, even after closing photoshop. When the screenshot was taken it was at 93% encoding and dropped a little. I have an i3 3.4gz dual core and have never seen it go above 50%, and even that was just a spike. The system also has 8gb of ddr3 ram on windows 7 64bit.
The dvd burning appears to be done but the program won't respond, it's now fluctuating between 0-5% of my cpu but is still not responding. It doesn't have the actual not responding, program frozen error, and makes me wonder if it is done burning.

Thanks for the reply and considering the comments.
Please remain with the "Fit Content to Available Space" option with a check mark next to it.
The only time that I disable that option by removing that check mark is when I get a Data Rate error message which forces me to remove that check mark so that I can manually set the Bitrate to lower value to enable the burn process to proceed.
783 MB at 1.69 Mbps (megabits per second) is definitely the lowest quality bitrate set. The maximum bitrate in Premiere Elements burn to is 8.00 Mbps.
If you are using a standard DVD disc (4.7 GB/120 minutes), in reality that 4.7 GB is 4.38 GB for your disc capacity. The Premiere Elements burn to DVD uses a variable bitrate which means that your max 8.00 Mbps will vary across the DVD being produced.
If you are seeing a No Disc error in the mix, that is another matter...there is a known error in 13/13.1 which requires deletion or disabling of the OldFilm.AEX file. This has been written about here a lot.
Local Disk C
Program Files
Adobe
Adobe Premiere Elements 13
Plug-ins
Common
NewBlue
and in the NewBlue Folder is the OldFilm.AEX file that you delete or disable by renaming it from OldFilm.AEX to OldFilm.AEXOLD.
So, please look at that, leave the check mark next to Fit Content To Available Space (if 8.00 Mbps is much less than 8.00, then consider a Double Layer Single Sided DVD (8.5 GB/240 minutes, in reality 7.95 GB).
We will be watching for your progress. Any clarification needed, please ask.
Thanks.

24" IMAC RAM MAXED OUT...

I have the previous Imac 3.06 24" duo and have 4g of ram on board. Is there any third party work around for the 4g maximum ram on this machine? I'm finding some of the newer adobe apps running a bit sluggish.
I think I know the answer to this but I couldn't resist the question...

Check in your user manual for the specs required for your model. You can then buy any memory module meeting those specs. I believe they are 200-pin PC2-6400 (800MHz) DDR2 SO-DIMMs.
You might try macsales.com or datamem.com.

After upgrading to 10.5.4, CPU keeps maxing out and system runs slower

Hi there,
I upgraded to 10.5.4 last week and quite frequently my CPU starts revving up and stays at a high level until I put my iMac to sleep. When I did my weekly reboot last Friday it seemed to not have the problem for a while, but then it came back again pretty quick. By checking Activity Monitor I found out that my resources are maxed out all the time, I've got about 80% CPU attached to Safari right now. Applications seem to load slower, everything runs a bit slower when it's like this.
I found under System Preferences > Energy Saver that I had my Processor Performance set to Highest, so I switched that to Automatic, but I'm still having this problem.
Can anyone help me with this?
Travis

Thank you, Pondini, that's all I was really asking about in the 3 (4) previous messages. I wanted to know if I could download the combo updater and install it over top of the 10.5.4 version I downloaded through Software Update. Thanks for the confirmation. I did download it this morning after getting your post and have installed it.
Initially, after installation and reboot of the combo update 10.5.4, my CPU maxed out again for a little while, and I checked Activity Monitor and it said a program called "Pattern ?" was hogging the CPU, the ? refers to a second word that I didn't write down at the time, I think it started with the letter M.
I had my iMac turned off for a couple hours after that. When I turned it back on, I was ripping 4 CD's into iTunes and so it sounded like the CPU was running high again through that, but I think that's typical for when I'm ripping a CD. Anyhow, right now the CPU is running normal, about 20% of total cycles used and that Pattern ? whatever program has disappeared from the list. So maybe that was something that the Combo Updater 10.5.4 was using to fix a problem and it might be back to normal again.
So, so far so good, thanks to the people here who have helped. I will post again if the problem persists.
Also, Pondini, thanks for reminding me to check posts in the forum for information. I almost always do that initially, before I post my question. I did that this time, but I had no idea at the time that downloading the combo updater would be the solution as I was scanning the forum for people who had spiking CPU's, not any other type of problem. I suppose in hindsight, after finding that combo updater might be a possible solution to my problem I should have ended this thread and sought new information, posed a new question / post if necessary. But like you say, I would have found other posts about installing combo updater.

Beginning of song play causes iTunes to max out CPU and rewrite library

I'm experiencing a strange problem with iTunes for Windows. Whenever a song plays, about 5 seconds after it starts, the CPU maxes out for 20-30 seconds. This occurs either when the next song plays in a playlist, when I manually start a song, or if I've paused a song in the middle and start playing it again. I used a process monitoring program, and it's not the iTunes process that maxes out the CPU when this happens, but the system process, and when it happens it always shows that it's writing to three files, sequentially in this order (with the first two being written to twice):
1) [iTunes Music Folder]/iTunes Music Library.xml
2) [iTunes Music Folder]/Temp File
3) [iTunes Music Folder]/iT.tmp
4) [iTunes Music Folder]/iTunes Music Library.xml
5) [iTunes Music Folder]/Temp File
The "Temp File" has no extension. This is a really annoying problem; it's been happening for about two days, but I can't think of any associated system change. I'm running Windows XP SP 2 with iTunes 7.0.2.16. Any help with this would be greatly appreciated.

I do have a very large library--about 6000 songs. However, it's been that large for a long time, with no problems. It seems like it usually just updates the library when it closes. If it's been doing it on every song play before, it hasn't been taking 30 seconds, but something so small that it doesn't show up on my process monitor, which I'm constantly paying attention to.
It doesn't seem like this is a hardware problem, but some setting or something that got changed to make it rewrite the entire library every time I edit it.
I did check the Windows Event Viewer and couldn't find anything helpful.
A couple other things that I've changed recently that could have an effect:
1) Yesterday I set a bunch of songs to not come up on iTunes shuffle; before I hadn't used this setting.
2) I attempted to make iTunes treat some mp3s as podcasts so that it would remember their play position. In the process of doing this, it decided that it wanted to re-download all of the back episodes of a particular podcast I subscribe to. I then figured out that you can set particular songs so it remembers their playback position, and instead just added those mp3s normally and set that option.
I unset the "don't use this song when shuffling" option for all songs, and also deleted my subscription to that podcast, to see if those things would have any effect, but they haven't. It seems like the podcast thing has something to do with this, though, because I think the problem started around the time that I tried that. Any thoughts?

Maxed out CPU Usage, happens suddenly, no obvious cause, please help!

I've had an XServe-G5 running well for about 18 months, with anywhere from 2-5 active users at one time. The server is only running AFP, Software Update & FTP services.
For the last 2 months, without warning, the CPU usage will max out, with only a small amount of disk & lan access with it.
I've found a less than ideal solution . . . . the cpu max out seems to be linked to 1 or 2 users logged in at one time, but not always the same users, if these users disconnect then the CPU usage returns to normal. I haven't found a way to identify which user/users it is, so I disconnect them through 'Server Admin' one by one till I get a result.
This goes on up to 5 times a day. I've checked the AFP access log when the problem happens, but can't see anything there that isn't there normally, the error log has no events. When there are no users logged in, other than the local 'Admin', the problem does not occur.
We've resorted to only logging into the server when needed, but it's getting to be a major pain.
Please help!

Many things can cause this. What do you see in "top"?
One example is when you hit the "corrupt .DS_Store" bug in AFP. See afp548.com for a discussion, e.g.:

Router - CPU maxing at specific times of the day every day

Hello experts
I'm just writing to get some help with a cpu max-out issue that happens on almost all the routers in the network at a particular time in the day - everyday.
I understand EEM traps or tcl script might be useful but since i am not good at either, i'm looking to find if someone with that expertise can kindly provide 'working config examples' for any method to capture the show proc cpu etc to spot the possible hacker/troublemaking pc etc.
many thanks
aravind

You can have the router send snmp-traps based on CPU thresholds you set as explained here http://www.cisco.com/en/US/docs/ios/netmgmt/configuration/guide/nm_cpu_thresh_notif_ps6441_TSD_Products_Configuration_Guide_Chapter.html
I hope it helps.

CPU Maxes when recording. (Time machine?)

I have this super annoying issue.
Every once in a while the cpu maxes out and I'm unable to use logic effectively. Meaning It is impossible to record due to pops and clicks from a maxed out CPU.
However, Activity Monitory only shows one of my cpu's at 13% and it looks great. Restarting logic does not help. I must restart my computer to begin recording again.
I just noticed today that this started happing when time machine started backing up.
Any ideas?

How do I get my iTunes (both purchased and cd's) into the cloud as I cannot use match my iMac and MacBook are too old to use the right OS and maxed out RAM memory upgrades, but have iPhone 4S and now 64gb iPad and libraries on desktops plus iPod!!

So very excited bought iPad and new speakers today! Want to get all my music sorted as across iMac (G5), MacBook os 10.6 (maxed out ram and memory) and old iPod. Saw Match would be an option but can't use due to old OS so I can get the raw music library files but then what do I do to get all in one place? Any help appreciated.

A good route would be to attach a USB drive to the macbook. You can use the drive to assemble a copy of all of your music from your various devices. iTunes on the macbook can be used to create a new library, located on the USB drive, into which you can import all of your music.
Two major benefits:
1. From here you can run iTunes Match across your entire music collection; and
2. You will have created a full local backup of all of your music on the USB drive.
Once complete you will be able to access the music from any iDevice capable of running iTunes Match, Do remember as you add music it is important to maintain a local backup in order to keep your music safe.
