G5 Mac OS 10.5.8 - coreaudio cpu usage out of hand
I have a G5 imac (1.6 GHz ) with 2GB ram. I am running a newly (March) installed Mac OS 10.5.8. My system is patched with all updates. After about 1 month of use, I began to see poor performance. The activity monitor shows that the coreaudiod process is running at 25%-90+% maxing out the cpu at 100%. I don't get the not responding message. There have been times when the sound is not working - I notice this from the sound of sending email in Mail. (it doesn't happen). A restart will fix the problem (cpu usage and sound) for a while. It seems I have to reboot on a daily basis though. The only additional pieces of software that I have installed since the fresh system is: Office 2004, Adobe Acrobat reader. I mostly use Safari and Mail (they are up all of the time.)
Can anyone suggest anything to help me solve this issue. When this isn't happening, the system runs like a charm. It is just frustrating having to always reboot. I have taken a few steps like dumping the preferences.
I would start by doing some basic maintenance:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard. These utilities have limited or no functionality with Snow Leopard and should not be installed.
OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc. Other utilities are also available such as Onyx, Leopard Cache Cleaner, CockTail, and Xupport, for example.
For emergency repairs install the freeware utility Applejack (not compatible with Snow Leopard.) If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that AppleJack 1.5 is required for Leopard. AppleJack is not compatible with Snow Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. Carbon Copy Cloner (Donationware)
6. SuperDuper! (Commercial)
7. Intego Personal Backup (Commercial)
8. Data Backup (Commercial)
9. SilverKeeper 2.0 (Freeware)
10. MimMac (Commercial)
11. Tri-Backup (Commercial)

Erratic CPU usage out of hours
Hello all.
I have a xserve running 10.5.6
2.8GHz quad
4GB ram
build 9g55
services
- afp
dns
ical
ichat
netboot
nfs
OD
smb
sw update
web
and ive notice that over the past week, as soon as a few clients connect to the server the CPU usage will spike really high and not return to normal idle.
EG. Last thursday we had 180users connect to the web service and i saw the usage spike to 80% then friday it sat at ~30% all day then yesterday when there was nobody onsite or connecting to the server the CPU usage spiked to double the original ~30% >> 60%
I can simply reset the server and values will return to normal but there has to be a reason..
one thing i have noticed is that when the CPU load sits there when its high it will create a saw tooth lookReally?! That's really encouraging, I wasn't aware that it would be so IO bound, since I'd seen it behave as described when working only across both internal drives - I might have expected it on external Firewires. Thank you so much for the information Patrick, I'll be looking into RAIDs in the new year.

InDesign CS 6 - Mac OsX 10.8.5 97% cpu usage
Hello
after migration from 10.6.8 to 10.8.5 (with clean install), on a Mac Pro 3.1, 2,8 Ghz Quad-Core Intel Xeon, 10 Gb ram, GTX 650 Ti 2 Gb GPU
simple resizing window InDesign CS6 take almost 100% of CPU, into open file there are just 2 pdf imported files of less than 2 mb each.
The issue appear with both best and default/typical visualization.
(sorry, I can't find InDesign forum community to start discussion)You can't migrate Adobe software. It will often not work correctly because not all files are moved.
Use the Adobe Cleaner app to clean off what you copied over:

Hey everyone,
I was just checking my Activity Monitor and I have nothing running/open on my mac. However, when examining the CPU usage, the "Dock" seems to be constantly fluctuating between 0 and 12 CPU. Is this normal? Could anyone check their activity monitor and let me know if theirs is the same?Yes, you can quit the Dock as often as you wish. You can also force it to quit and rerun by opening the Terminal application in your Utilities folder and entering: killall Dock then press RETURN. Or you can use the force quit options within Activity Monitor.
The windowserver is the process that performs all the screen drawing such as open windows and window content. I can suggest something you might try: Download and install a utility called AppleJack - VersionTracker or MacUpdate. Carefully read the documentation then follow the instructions on running the utility. This requires booting into single-user mode. Just run AppleJack in Auto mode. AppleJack will perform several maintenance chores that may clear up the problem with WindowServer.
Additionally, I would suggest the following:
Delete caches to resolve some problems:
Boot into single-user mode. After startup is completed you will be in command line mode and should see a prompt with a cursor positioned after it. At the prompt enter the following then press RETURN after each commandline:
/sbin/fsck -fy
If you receive a message that says "*** FILE SYSTEM WAS MODIFIED ***" then re-run the command until you receive a message that says "** The volume (nameofvolume) appears to be OK." If you re-run the command more than seven times and do not get the OK message, then the drive cannot be repaired this way.
If you were successful then enter:
/sbin/mount -uw /
rm -rf /System/Library/Caches/*
rm -rf /System/Library/Extensions.kextcache
rm -rf /System/Library/Extensions.mkext
rm -rf /Library/Caches/*
reboot
I suggest you print out the above to be sure you do not make any errors when entering the commands. When in single-user mode you have 'root' access, so it's important that you not make any mistakes. -
Please do not tell me to Buy a Mac computer. I all ready have 23 in my family and they are all at least 1200 miles from me now.
Try reinstalling iTunes. Or, if you already have iOS 5, you can update from the phone.
About the CPU Usage: if you have an old computer, and you're running the latest version of iTunes, the CPU will go up. -
Cpu Usage High On Mac Air (A1466)

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]

High CPU usage for AppleVNCServer (Screen Sharing) on Mac Mini (mid 2010)
Steadily around 90-100% (on a dual-core), no browser opened, just iTunes, VLC and a couple of low-impact servers.
I wasn't worried about this since my Mini (no monitor, all Screen Sharing) has always done that but I just realized that Screen Sharing into my iMac or my MBP 13in (mid 2010, same CPU as Mini) does not make them go nearly as high (5-15%).
As a result, it runs pretty hot when I VNC into it.
Any suggestion?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 -
Mac goes over 100 percent cpu usage
As seen in the picture, the game called 'runescape' which i was playing reached 171 percent cpu usage on my computer. My computer never crashed from playing this game but crashes alot while playing Dota 2, once when I crashed from dota 2, the computer lagged showing my activity monitor which showed that dota had 100.1 percent cpu usage. Is this a problem of the game or the computer? Multiple friends of mine have played this game and never once crashed on it.
It is a problem with games in general: they use a lot of CPU power (and heat the CPU up correspondingly). Over 100% is not very spectacular, because modern CPUs have 2, 4 or 8 cores, and each has a maximum of 100%. If you have a 4 cores cpu the run escape is taking almost 45% which is a lot.

Skype vdeo call and high cpu usage on Mac
Hello,
I have seen many posts around skype video call causing extremely high CPU usage which in turn causes a lot of heat and fan starts to go crazy. This does not seem to happen on Windows. I have trawled various forums and tried everything but to no avail.
Finally the workaround that worked for me was simple - during a call when CPU usage is going through the roof and the fans going crazy - just share your screen for a few seconds with the caller and then unshare. CPU usage dramatically falls off and stabilises at around 38% to 40%. I have noticed this my Macbook Pro (2013 2.3ghz, 16gb RAM) running Yosemite.
This is definitely a problem with Skype. Guys; please fix....Did the sharing and unsharing of screen stabilise your CPU usage? I also tried deleting the Library/Caches/com.skype* directory and whilst it helped initially, in the long run it did not work. The only thing that worked for me was sreen share and unshare.
Personally I am just getting more and more disappointed with OS X. The way they have implemented HiDPI support with scaling (downscaling and then upscaling) is just insane and a lot of applications struggle. I am sure this is not the root cause of the high CPU usage issue for Skype. It's not long before I come off the Apple ecosystem altogether. -

I've tried having hardware acceleration for both flash and firefox on and off
I turned off all my apps and plugins and when that did nothing I turned back on the ones I need. I never had a lot of apps to begin with. only a max of 5. I had quite a few plugins, but i disabled all but quicktime, flash, and silverlight. I have those three set on "ask to activate" so none are "always active" anymore.
I also tried a couple things from the FAQ and forums here about changing a few settings in the "about:config" setup.
A few of the above things initially worked, but after a day or two it'd be back to sucking up my CPU and memory. I would then try the same thing again, and this second time there would be no improvement.
The real memory will fluctuate between 200 MB and 1.7 GB, and has done so for quite a while.
Even after I've left streaming sites, and sites with lots of images, and I'm not downloading anything, the memory and the CPU will still do that. I only have a handful of tabs open at a timeusually, and all of them are mostly text. I'll quit and reopen firefox, which will initially bring the memory and CPU usage down, but it inevitably climbs up quite quickly, regardless of my tab usage. It'll be the same if I'm playing a flash game or scrolling through blogs.
I never had any of these problems with Firefox 23, and my internet usage habits haven't changed at all. I had some of this slowness a few times with version 24, but nowhere near as bad as this, or as constant. Almost everyday I end up googling for other ways to speed things up. Everything I do never slowed down Firefox on earlier versions.
I've tried all my usual tasks on Safari which will never climb above 30-40 MB of memory, even on netflix streaming, or flash games, and the CPU will average around 8 and 11%.i'm also having major CPU problems w/ FF 29.0.1. when i restart the app it calms down again but after loading tabs it steadily climbs up to 100% after not too long. i have checked out the 2 CPU links/articles above and do all the basic troubleshooting and tips, but with all the FF tools & add-ons isn't there some sort of CPU monitor that has the ability to display which extensions/scripts are hogging the CPU? Activity Monitor on Mac just shows the total used by the app. it's impossible in my case to efficiently disable dozens of add-ons & scripts, restart, and test each one by one b/c it can take several hrs before the CPU starts to spike high again. i have no time for this.

Macbook Air running extremely slow - kernel_task at 300% cpu usage
I purchased my Macbook Air roughly 15 months ago and it's performance has constantly been impressive since I purchased it - until roughly a fortnight ago. I came home from work one afternoon and it was running at a snails pace. I had recently upgraded to Yosemite though I'm unsure if this had anything to do with it. I had also recently installed FitBit software to sync to my new FitBit flex.
It has continued to run in this manner constantly since the problem began. It is ridiculously slow, every single request takes a very long time to respond. Logging in takes forever. When I click on an app to open it, the icon bounces for 30 seconds or more, and it's not a smooth bounce either, it's quite a jagged bounce!
I'm hoping someone is able to provide some advice, guidance or help. The laptop is no longer covered by the 12 month Manufacturer Warranty, and I did not purchase an Apple Care plan as no Apple product I've owned before has experienced issues like this.
This whole experience is killing me! I'm suspecting hardware failure and I'm just so sad that this could happen to the laptop I've loved so much since I bought it!
The problem:
The kernel_task process is constantly running at 300% or higher cpu usage, with Activity Monitor indicating the processor is being maxed out by a system task. Also, the laptop's fan is constantly running at full capacity - from the moment the laptop turns on, or wakes up.
What I think the problem might be:
As a result of many, many Google searches, it appears that this behaviour may be due to the Macbook Air thinking it is overheating - and I will clarify here that it certainly is not. It is cool to touch, always, when this problem occurs. (yet the fan is almost taking off!). As a result of the MacBook Air thinking it's overheating, it not only is running the fan at a very high RPM (confirmed with iStat), but it also is intentionally choking the system with 'simple requests' in attempt to cool the computer down. Apparently this is a built-in feature of OS X. The kernel has priority over user tasks, causing all user tasks to be granted a lower priority, causing the computer to run INCREDIBLY SLOW. Even as I'm typing this, I'm about two sentences ahead of what is showing on the screen!
Steps I have taken:
- Read widely across the internet with every possible relevant search term I can think of
- Downloaded iStat to see if any of the temperatures are too high (they all seemed fine..)
- Disabled Bluetooth and Wifi. (no change)
- Reset SMC (multiple times.., no change)
- Reset PRAM (multiple times.., no change)
- Drained the battery completely (2 or 3 times, no change)
- Install Windows 7 on BootCamp in attempt to bypass the issue (CPU usage was 100% constantly in Windows also)
- Uninstalled FitBit software (no change..)
- Uninstalled other software I did not need (no change..)
- Attempt to boot into Safe Mode / Recovery Mode (even in this modes, the same thing is happening)
- Repaired Disk Permissions
- Backed up all personal data
- Used the built-in Internet Recovery mode to format my Macintosh HD and re-install a fresh copy of OS X (Mountain Lion). (no change…)
- Re-upgrade to Yosemite (no change..)
I've downloaded EtreCheck and here is the output:
Problem description:
OS X is running incredibly slow. kernel_task process is constantly using 300% and upward CPU usage.

Dec 20, 2014, 02:15:38 PM Self test - passedHi,
I have an update so I thought I would share in case any other users are experiencing a similar problem.
I made an appointment with the Genius Bar at the Apple Store.
I went in and they ran a thorough diagnostic check on my Macbook Air and determined that the sensors were indeed faulty - several were providing no information "No reading" instead of providing a temperature. Thus, the Air was unaware of the temperature across multiple components.
Despite the laptop being outside the 12 Month Manufacturer Warranty, the Apple Store determined that it was covered under warranty through Australian Consumer Law - the laptop is now in for a complete repair under warranty at no cost to myself.
I couldn't be happier. -
Since 10.4.6 Update: "ATSServer" with high CPU-usage when opening PDFs
Since I've updated to 10.4.6 my system is very slow when I open PDFs (in "Preview" or "Acrobat").
This is caused by the process "ATSServer" which goes through every file in "~/Library/Fonts" (I have over 4.800 files there - but just a view are activated by "FontBook") and so it takes very high CPU-usage.
I didn't have this problem bevore the update and I didn't make any changes on my font settings.
I've cleaned the font cache, but it doesn't help.
Any ideas?
Ciao

PowerBook G4 17'' 1.67 GHz Mac OS X (10.4.6)
PowerBook G4 17'' 1.67 GHz Mac OS X (10.4.6)I haven't noticed any change myself, Dan, but I have the 2 GHz model.
One thing I HAVE noticed though after OS updates is that they can often result in a fair amount of file and free space fragmentation immediately after installation. OSX's routines will deal with fragmentation of small files , but not of large ones (over 20 Meg), and it won't deal very effectively with free space fragmentation. If your HD is getting full this can cause significant slowdowns, especially where video is involved.
You should also run DiskUtility and check for any directory and permissions issues.

Question about CPU usage for video playback
I've asked a related question already on the Safari forum, but would like some clarification, please.
The speed of this iMac is 400 MHZ and whenever I go to YouTube or almost any other site that requires video I see that the CPU usage can peak way up at 80% or more. I have Flash 9 installed which has a minimum of 500 MHZ, so I get pretty choppy video, but that's not the issue here. I can live with that. I keep any other applications closed. I'm often running a small fan over the top of the iMac to help vent the buildup of heat. I can monitor the temperature at the Hard Drive and I suppose that gives me an idea, of sorts, about general temperature conditions inside.
The answer I got was that this kind of CPU usage could be detrimental to the processor as it builds up excessive heat and to keep this kind of video to a minimum.
My question is can anyone roughly suggest what a maximum time on YouTube, for example, would be, 2 minutes, 5 minutes, is 10 minutes too long? I have plenty of RAM at 768. Some guidelines?
Thanks.Hey WZZZ,
Thanks for the star and kind words.
I'm the de facto Mac guy at my kids' school and we have around 25 iMac Slot Loaders working there. You can imagine they get abused quite a bit. There are 10 running Garage Band in the Music Department. That puts a tremendous strain on the CPU and I'm actually surprised that they run it so well. My son had a 600 iMac running GarageBand, he was complaining that it was getting jumpy and when I looked at it he was running 10 unlocked tracks simultaneously! So now he has an eMac G4 800 and that of course runs a lot better.
So to sum up, with all the abuse of those machines in terms of the CPUs the problems I have with them have nothing to do with that. The problems have more to do with parts of the OS that they toss, headphone jacks abused, CDs jammed in the slots, and the like.
A couple of other related things. I've got Hardware Monitor, demo, installed and I think it reported it could only find the hard drive sensor, if I'm not mistaken - nothing else on this Mac with a sensor. Is that right?
I see references to CPU sensors on 400 iMacs but on the 400 I have here for repair Temperature Monitor reports no sensors. Perhaps there were different versions of the 400.
But very good to hear that the fan is a good idea for CRT related things. Should I keep the fan running-mostly for that hard core CRT stuff- even if the computer is sleeping and the room temp. is only around 62-64 F.? (We need to put on warm clothes to sit in front of this thing now, but worth it to keep this old machine happy).
On the one I did the fan pushed the airflow in the direction of the passive flow of the iMac - in at the bottom and out the grill by the handle.
One more question, more out of curiosity than anything else: If I move this small clip-on fan close to the case - right now it's about 3 feet away and the image is stable - the screen begins to flicker and flutter quite a lot. My theory is that that's happening not necessarily because of electro-magnetic interference from the fan motor, but rather, because the back of the tube is getting cooled unevenly. What do you think?
Well the classic failures that I see in the iMac are in this order:
1) Dielectric breakdown of the flyback transformers internal insulation. This is heat/age related and a common problem with CRTs in general.
2) Breakdown of high voltage electolytic capacitors and regular high voltage capacitors on the neck board and PAV supply.
3) Solder problems with the flyback itself. This is diagnosed by the upside down boot technique.
I used to repair these problems but now it's easier for me to swap the Firewire boards into working 350s. I've got 12 of those in the basement currently.
