Kernel_task and windowserver high cpu

Please help me find a solution,
my macbook has been acting strange,
it freezes every few seconds for the las 4 days.
It all started one month ago, when the resolution of the screen changed all of a sudden as if there was another display
and it was trying to find the right resolution. That problem went away after checking system preferences. Then I noticed the brightness of the display would be set to 100% everytime I started the mac, It doesn't save the last setting applied. I still having been able to solve that.
Now, the mac started freezing constantly, it began happening 4 days ago, the OS just gets stuck,
no matter what application I'm using. I checked on Activity Monitor and shows a high cpu usage, both by kenerl_task and windowserver.
If I'm right windowserver is related to display options?
I really would like to find a solution, since there are times
where the mac is back to normal and everything works great.

Google Earth Plugin and LabVIEW: High CPU usage when adding placemarks

Hi,
I posted this question on stackoverflow earlier this week but feel it might be better suited to the LabVIEW community specifically so I'm reposting here:
I'm writing an application which uses the Google Earth Plugin to display events on the globe. Each event is a single point kml placemark with an icon which is a 3kb png file. Placemarks are uploaded to the plugin as they are received by the software. I am experiencing increasing CPU usage with the number of placemarks that are added.
I have tested displaying a new placemark every second and running until the software running the plugin completely froze (graph attached). The GEPlugin (green trace) stopped responding (i.e. the globe did not respond to the mouse) at around 1200 placemarks added and CPU usage was at ~30%. When the software itself (red trace) froze the plugin was using around 50% CPU and ~3700 placemarks had been added). After the freeze, no new placemarks were added which caused the software to respond (but not the plugin) so I could clear all the placemarks. After the placemarks were cleared from the globe, the CPU usage of the plugin returned to around 5% CPU.
So what I've seen is that GEPlugin CPU usage increases linearly with each kml placemark added. Is this the expected behaviour/ a normal limitation of the plugin? If not is there a more efficient way of adding many placemarks to the globe?
I am using GEPlugin version 7.1.1.1580 (API version 1.010) and LabVIEW 12.0f3
Please see the test results attached. Any input greatly appreciated!

Hello,
I have had a look at your graphs and understood what you are trying to do. To me it seems that as the image gets more complex it gets harde to render which wold likely cause increase in CPU usage resulting in the freeze. I would suggest you try running the program on anoher computer to check on the RAM front of things. If this is a limitation of the GE Plugin then unfortunately I can not do much to help, but if you think this is a problem coming from your LabVIEW code then you can post your code here and I can take a look.

Latest flashplayer not work well, even the early version in 11x and has high CPU usage

why is it that flashplayer 11x always has a High CPU Usage? detected by NOrton Antivirus

you can't rely on norton antivirus.
but if you check your active processes and directly confirm a problem with flash player 11+, uninstall your current flash player (http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-mac-os.html or http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html) and install an older version: http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html

ATSServer and MDWorker High CPU Usage

Lately, Activity Monitor shows 'ATSServer' and 'MDWorker' as using an unusually high cpu usage. I tried to google the issue and all that I found out is that ATSServer and MDWorker deal with Spotlight indexing.
Currently, Spotlight isn't indexing my drive. I've tried to force quit both processes. They relaunch and take up the CPU again. I've restarted the machine to no avail.
Help?

Thanks for posting! I've been in the same boat for the last few days, with my MacBook's fan howling at me as it indexed a giant zip file. *shakes fist at MacBook designers* It needs TWO fans, you lugnuts!
Never once did I consider simply adding my downloads drive to the "ignore" list. You've saved my sanity!

Windowserver high cpu usage and OS laggy

After upgrading to Yosemite the graphics is laggy and also WindowServer is hogging CPU.
I've tried http://www.macissues.com/2014/10/20/prevent-the-windowserver-process-from-draggi ng-yosemite-down/ without any luck

Hi, try this: Disable the "Display have separate Spaces" in Mission Control
LogOff and Login again, check the process...
all fine?

The kernel is using excessive processor cycles. Below are some possible causes for the condition.
Throttling
When it gets high temperature readings from the hardware, or a low-voltage reading from the battery, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to
a buildup of dust on the logic board
high ambient temperature
a worn-out or faulty battery in a portable
the malfunction of a cooling fan or sensor
Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on battery power, the fault is in the battery or the logic board. If it happens only on AC power, charging is causing the machine to heat up. That may be normal on some models. CPU usage should drop when charging is complete.
Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a bad fan or sensor.
If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or booting in safe mode. Note, however, that disabling a system modification without removing it or booting in safe mode may not be as easy as you think it is.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
External display
Connecting an external LCD display to some MacBook Pro models may cause this issue. If applicable, test by disconnecting the display. You might get better results with a newer LED display.

thanks, might be a workaround also for me, but actually i didnt want to use littlesnitch (dont like it to much).
what are the rules you have for blocking icloud?
another approach could be to exclude the access to certain hosts in the network / proxy settings...

My macbook pro i7 (2011 version) has a loud fan and high cpu % when I have Skype on or when I am on Safari. Help please!

My macbook pro i7 (2011 version) has a loud fan and a high cpu % when I have Skype on or when I am on Safari. My laptop would sometimes freeze for a while and it is usually hot. Has anyone else encounter this problem and know how to fix it? Thanks!

Skype is a very resource intensive activity...it has been reported on here users are seeing cpu temperatures on the order of 80-85 °C, within the limits of the cpu, but still hot to the touch.
Make sure nothing else is running so you keep the thermal load down.

High CPU Problems With Screensavers and Flash Player - FYI

Upgraded my 1.42 Ghz PPC MacMini (1 GB RAM) to Leopard, fresh install and suffered high CPU problems as outlined in various other threads.
Fixed major 100% cpu and 100% FAN issue by removing The Weather Channel Screensaver - so have a look at your console system info and see if a 3rd Party screensaver is causing a problem, or if no 3rd party screensaver, try using a simply screensaver like Forest.
Safari/Netscape/Firefox also were using high CPU when a webpage was using Flash, I removed Flash Player 9 (latest version) and cpu load decreased dramatically.
Go here for uninstall DMG
http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157
Hope this helps someone else until there are fixes.

Just wanted to clarify that the Flash and Screensaver problem is still ongoing even after the latest QT updates as of Nov 07.
The Flash problems is with Flash images/code that use moving graphics/user input, such as those adverts you see where you push a button to punch Paris Hilton.
I think the overall problem is with the way QT/Core Image/Core Animation is different in Leopard compared to Tiger. As have now often witnessed iTunes just displaying the Cover Flow image area and nothing else (everything else in the application area is white) when going between applications, clicking on the iTunes icon in the dock refreshes the image okay.

ICloud Photo not syncing + High CPU process (Win 8.1 pro)

This is a new persistent issue with my iCloud and I can't figure out how to fix it permanently because I was able to fix it few days ago, but issues return back a day later! So here's the full story...
I just received a new (AWESOME!!) Surface Pro 3 i5 256 GB tablet with Windows 8.1 professional. I installed iCloud on it as well as iTunes and Quicktime (the basics isn't it?). When setting up my iCloud account first, everything sync up correctly but after a few days (3-4 days), I notice than my Surface tablet are becoming pretty hot and making some fan noise (common Surface issue) when I didn't use it really. So I checked for a high-CPU process and I noticed than "iCloud Photo Stream Downloader" are stuck at 30-35% CPU for an hours ago. Moreover at this point I realized than my photos are not syncing for a few days. I fix the high-CPU process by rebooting, but my photo are still not syncing at all and after a few minutes after reboot, the "downloader" process stuck back to 30-35% and still not syncing!
So I first try some of the workaround found on the internet like sign out iCloud app, then kill all iCloud related process and delete folder %appdata%/Apple/Mediastream and reboot and sign in... same thing... after a few minutes, high-CPU usage + not syncing! I try to "repair" iCloud installation... same thing (high CPU + not syncing)... I uninstalled iCloud + reinstalled... same thing!
I finally fix the situation by uninstalling ALL Apple related software (iTunes, iCloud, Quicktime, Apple Soft Upd, Apple Mobile Sup, Apple App Sup, Bonjour, etc) and thereafter deleting all "Apple_xxxx" folders in %appdata% and also remove all registry keys from the Windows Registry related to Apple. Reboot then reinstall iTunes first and then run "Apple Soft Upd" to install automatically iCloud + Quicktime... then reboot, sign in and then the photo finally sync this time and no high-CPU process!
But a days later... High CPU + Fan noise on the tablet... so checked and the god **** "iCloud Photo Downloader" are again stuck at 30-35% and no more photo sync (I saw the old photos, but not the last day's photo are not sync).
Anybody experience this situation and know how to fix it PERMANENTLY? I checked at my Apple iCloud LOGS and the only thing I saw that can be suspicious is the last line of the log who's :
[2472 @ Tue Nov 11 19:45:09 2014] [YSLog ApplePhotoStreamsDownloader.exe] defaults key ShouldLog in domain ApplePhotoStreamsDownloader.exe is (null)
Please help!!

In fact I discovered later I have this issue on all my Windows computers... both Windows 7 and Windows 8.1, both MACs (BootCamp) or true PC computers. Except only the Surface Pro 3 tablet seem to have the HIGH-CPU process issue, but all my other Windows PCs stopped syncing too after a few weeks or so.
I just build a BRAND NEW HP Pro Desktop computer running Windows 8.1 Professional and a few days later iCloud Photo stopped syncing too... this is the straw that broke the camel's back! This PC is brand new and no other software are installed except iCloud, iTunes, QuickTime and Microsoft Office 2013 (Office 365). PC is brand new (1 week old) and iCloud Photos sync is already broken!
I also have a few Windows 7 PCs at home (HTPCs on TVs) where iCloud Control Panel is installed and after looking at them, they stopped syncing too for a while (many months ago) but I didn't noticed it yet because I don't check photos often on them.
For now I just give up and disabled the iCloud Photo Sync completely on all my Windows PCs. It only sync between my two iPads, my two iPhones and my two Macs computer (MBPr + iMac 27") and that's it... that's sad, but I'm tired loosing my time with that crappy software!
PLEASE APPLE!! MAKE ICLOUD FOR WINDOWS BETTER!!

Problem... High CPU load with HDD. Please Help

Hello all,
Im stuck. Ive got a MSI KA790GX which has poor HDD access/transfer, low burst rate and very high CPU load.
As far as i know the Western Digital 640gb WD6401AALS Black should be a fast hard drive. Which according to reviews/HD Tune,
should be:-
Minimum 60mb/sec
Maximum 120mb/sec
Average 95mb/sec
Access 12ms
Burst 110mb/sec
CPU 5%
No matter what I try, i always get poor results...
My MSI KA790GX
Minimum 41mb/sec ~ 54mb/sec
Maximum 104mb/sec ~ 108mb/sec
Average 86mb/sec ~89mb/sec
Access 12ms
Burst 60mb/sec ~ 80mb/sec
CPU 26% ~ 44%!!!!!!!!
I could accept not getting the same high speed results as the review/reference, even if the burst rate sucked.
But one of the cores goes to 50%-60% load during hdd activity. Thats just crazy!!
I have tried...
IDE mode, AHCI, RAID Ready, RAID Single Disk
SATA Port 1, 2, 3, 4 + 5
Different SATA cables
Flashed bios, cleared bios, optimised defaults, failsafe defaults
Windows XP 32bit, Vista 32bit, Vista 64bit. fresh installs
MSI CD Drivers, MSI Web Drivers, AMD/ATI Web Drivers
... and combinations of.
I have also tested the WD640gb Black on another older PC, with Nvidia (55?) chipset and slower (1.9ghz x2) cpu.
Transfer rates were slightly better than my KA790GX but, Burst Rate = 115mb/sec and CPU usage = 13%.
I also tried a Seagate 1.5tb (ST31500341AS) on both PCs,
Nvidia chipset
Minimum 65mb/sec
Maximum 134mb/sec
Average 107mb/sec
Access 14ms
Burst 83mb/sec
CPU 7%
On my MSI KA790GX
Minimum 55mb/sec
Maximum 120mb/sec
Average 100mb/sec
Access 14ms
Burst 87mb/sec
CPU 33%!!!!
Could someone please please help, ive spent hours and hours on this. Its doin my head in.
I just hope its something stupid ive missed, cos i still not used my HD4850 from christmas :-(
Thanks.

Not sure how to check PIO/DMA mode on a SATA device. IDE devices show DMA enabled.
BIOS version 1.4 - 29 December 2008, and now version 1.51
Fredrik
I have Vista 64, but i did try XP32 and Vista32 and got similar poor results.
I tested HDD speed with, HD Tune 2.55 and HD Tune 3.50 trial.
No auto-start programs really, Windows clean installs + any drivers.
Quadrifoglio Verde
CPU @ default 2800mhz, All mem bios options to auto/defaults
Windows Experience Index, CPU Score = 5.3
AMD Overdrive
Integer Computation = 8220
Floating Point Computation = 5325
Memory speed = 1770
Cache Speed = 10790
System Performance = 7403
Bas
I used HDTune because I could reference to other results. Whats a better program to use?
Windows Experience Index, HDD Score = 5.9.
But I have no reference and cant be sure of cpu load.
Sepher
Bios defaults to C&C and C1E off so i have tried them. Also windows power settings, balanced/high performance.
UPDATE
Reinstalled Vista64 but loaded the AHCI driver from the disk config screen. This seems to have stopped the high cpu usage during disk activity.
HDTune with Windows Power settings @ High Performance,
Min = 52mb/sec
Max = 106mb/sec
Ave = 88mb/sec
Access = 12ms
Burst = 77mb/sec
CPU = 3.4%
HDTune with Windows Power settings @ Balanced
Min = 54mb/sec
Max = 104mb/sec
Ave = 87mb/sec
Access = 12ms
Burst = 65mb/sec
CPU = 12%
So now transfer speed is about 10% slower than reference. But burst speed is terrible.
I also used IBM Feature Tool to change the HDD AAM to 'performance mode' 254 as suggested elsewhere.
Long shot as the hdd performs ok with other hardware. same results.
Also MSI support asked me to try a newer bios, version 1.51. same results.
Anyone know what the AMD 7-Series Chipsets Disk Performance Utility does, and should i run it in Vista64?
Thanks for all the replies, hope i can sort this, not played any PC games since Quake 3 on my ti4600...

MSI KT6 Delta LSR SATA to PATA High CPU Usage Problem

Well recently I've switch to my one of my other motherboards on my network to a MSI KT6 Delta LSR, it was working fine after a reformat, but I notice a few problems and that is 100% cpu usage for SATA to PATA, and vice versa, which seems really crazy. Then my network card performance is ISDN speed sluggish, and I tested my line to be working 100% with another mobo. But when I put another NIC on the same mobo it suffers the same speed problems.
Any suggestions? The rig is specs:
Barton 2500+
Antec QuietPower 350W
200GB Seagate SATA HDD
40GB Seagate PATA HDD
ATI Radeon 7500 AIW
Audigy 2 Value
Realtek 8139 NIC
MSI KT6 Delta LSR Mobo
2x512 MB PC 2700 RAM
Pioneer 107D DVD Writer
LG 16X DVD-ROM
56K Modem (A-open)

Shouldn't say what I don't know about SATA, but since I found below, I need ask if VIA 4in1 drivers are installed, preferably while in SafeMode I say:
http://www.google.se/search?q=cache:X6ewgPiIHYcJ:www.qdi.nl/cgi-bin/bbs/YaBB.pl%3Fboard%3DP4I865%3Baction%3Ddisplay%3Bnum%3D1074174096+sata+to+pata+cpu+usage&hl=sv
I recently installed 160g Seagate barracuda 7200.7 drive on SATA port. (I enabled the Bios using Auto) I have a P4I865pea-6al mother board, with two PATA drives . When copying files between the PATA drives on ide ports, to or from, the SATA drive, I notice the CPU usage goes up to 100%, but when copying files from one ide drive (the PATA drives) to another the CPU usage is very low.
Is there a bios setting that will allow me to copy files from the SATA drive to the Pata drives using a small amount of CPU power, found when just copying between the Primary and Secondary IDE drives? I am using Adobe premiere pro, which uses a lot of CPU power, and the high CPU usage of the SATA drive crashes this program? Any help would be appreciated

have you installed the newest chipset- and ide drivers ?

High CPU temps after kernel panic.

Recently I've seen my Mac Pro 8-core CPU temps rise pretty considerably, between 10°-15°C after a bone head move on my part.
After setting up a new Vista x64 virtual machine in VMWare Fusion 2, I was trying to get a Linksys USB to Ethernet adapter (USB200M) to work inside this virtual machine, but with little success. After tracking down a driver online which I thought at the time was a match for the chip on the adapter, I tried to load the driver manually in the virtual machine. This unfortunately resulted in an immediate OS X kernel panic; my first and only on this machine.
Since then, my CPU temps have been on the rise. Not sure if its even possible for a kernel panic to damage hardware, but I’m wondering if any low-level software damage resulting from the kernel panic could be causing the higher temps?
I tried a simple restart which did nothing. I have since run the extended Apple Diagnostics and everything appeared OK. Also, ran a “fsck” check and everything appeared OK there as well.
Any feedback, suggestions or advice?
P.S. This is an Early ’08 2.8GHz 8-core Mac Pro with 10GB third-party RAM. RAM has been thoroughly tested and running in the machine for over a year now without incident.
Thanks

No, ethernet ports work fine.
I use the adapter to connect a VMWare Virtual Machine directly to a VPN Netgear router which runs a remote VoIP service, available on Windows only. To make a long story short, I ran into all kinds of performance issues when connecting the Mac via Ethernet directly to this crappy little Netgear VPN router.
So, the alternative was to use the USB to Ethernet adapter to connect only the VM directly to this router. Definitely not ideal, but worked fine with XP.
It was when I upgraded the VM to Vista x64 and tried to install the driver for the adapter that I got the kernel panic and now higher CPU temps.
Still just curious if I could have damaged any hardware?

Airport Process utilizing high CPU utilization

I currently have a 13 inch MacBook Pro i7 (2012 version). Recently I upgraded to Mavericks. After using the computer for a day after the upgrade, I began to notice it becoming very hot and the fans running very high. Looking at the running processes i noticed that a process called "airport" was running and utilizing high CPU times causing the heating up and fans running. Once I stopped this process, the laptop went back to operating at normal levels.
Unfortunately this issue began to come back several times....the "airport" process starting at any time and utilizing high CPU utilization....again only by killing this process fixed this issue.
After seeing this behavior over several days, I decised to wipe the drive and install a clean copy of Mavericks in the computer. Thought here was that possibly something did not carry over correctly from the upgrade from Mountain Lion to Mavericks. Unfortunely this did not correct the issue with the "airport" process as it still is continiung to launch at any time and spike the processor until I manually kill the process.
I do not recall this issue occuring while running Mountain Lion so it seems to be specific to Mavericks at this point.
I was hoping to hear if any other have experienced this type of issues while running Mavericks.

You should be able to find the information you are looking for from the default Total CPU Utilization Percentage monitor. This monitor has a built in diagnostic task that will kick off when an alert is triggered to list the top cpu consuming processes.
To find which processes were causing CPU to spike, simply review the State Change Events history in health explorer for the machine that was affected, for the Total CPU Utilization Percentage monitor. I have modified my second screen shot
to remove machine names, but you should get the idea. If a cpu monitor went from green to red, it will run the diagnostic task and list the process information and cpu usage at the time of the alert under state change events.

High CPU for itunes and windowserver

I was away for a bit and when I returned I noticed a strange sound from my iMac. For some reason the hard drive was ticking furiously. Since I didn't use the computer I checked Activity Monitor. For some reason iTunes had 40-50% CPU and WindowServer used around 30%. Sure iTunes was running, but no song was playing.
Checking Hard Drive Activity I could see HDD was constantly reading approx 2,3 MB/s. Reading/second in was steadily at 400, and data read was 3,11 GB and climbing rapidly.
Has anyone else this problem? Has this something to do with the new iTunes 10.6.1 or Mac OS X 10.7.4 or a combination? What is wrong, and what can I do about it??
This has continued for a couple of days and restarts. No change.
Thanks! Joachim

I can't see why iTunes needs to read the disk constantly just becaouse of cover flow. Do you think this is a bug? I have never noticed this heavy load before, and iTunes almost always is in cover flow.
That's interesting ... I'm not sure if your one is a bug or not. (The Mini Player one seems to be: it showed up for folks with 10.6.0.x and has persisted through 10.6.1.7, as far as I can tell.)
If you've got the time, it would do no harm to report your issue to Apple. Here's a link to the iTunes product feedback form:
