OS X Mavericks :: Kernel Task Is Using Many Resources On Mac
Sep 2, 2014
I was working on my Mac but is coming very slow sometimes so I found the problem is the kernel task.
Lex I already use the Clean My Mac and since the first time I delete a lot of things I don't even remember how many. Should I format my drive?
About the iCleanMemory so the system will clear the RAM by it self or should I do something different or use another program?

I have a 13inch MBP running Mavericks 10.9.4 with a 2.7 GHz i7, 16GB RAM, 500GB HD. I just recently had the machine Factory Reset. The only APP's I've added are PAGES, NUMBERS and KEYNOTE. When I check the ACTIVITY MONITOR it indicates that out of 16GB of RAM MEMORY, 5.51GB is being used. Usually ACTIVITY MONITOR indicates that as much as 9GB RAM is being used. This MBP is 3 years old and I clearly upgraded the RAM from 4GB (I think) to 16GB. Since this MBP used to run with only 4GB of RAM total; it seems to me that the current amount of memory being used, from 5.51GB up to 9GB out of 16GB total RAM is unusually high. In addition, the above numbers were displayed when only Safari and Activity Monitor are running. Is this normal for Mavericks OSX?

Noticed i was uploading at high speed (8MB/s) constantly. So i check activity monitor, and kernel_task is uploading huge amount of data, so far 20+gb this morning...
I'm not getting a massive CPU usage (10-15%).
Tried restarting, just starts up again after a couple of minutes.
Is there any specific reason Kernel_Task seems to think he owns the place? What gives? It's like I turn my MacBook on and he's all like "oh hai! Ize just a system task! 50mb of memory? That's cool that's cool" Then only 2 hours later he's all like "Nah man, I just needed some more room see, it's like 120mb ain't dat much, k?"
I know that OS X handles ram real good and all, by freeing memory when it's required for higher-priority tasks, but I also know that it takes a bit more time to clear that memory AND re-allocate it...
So, is this a memory leak? And while I'm at it what about iChat Agent and Colloquy that are battling out to be RAM champ?
I've been recently realizing that every time i use safari or socialite for a few mins I get a lot of 'beach ball' time. The application would show in red (not responding) in activity monitor and kernel_task would have over 1,900 threads, that will decrease slowly after I force quit the applications.
My computer keeps freezing and applications keep shutting down unexpectantly. So when I went into the activity monitor I saw that Kernal_task and inkjet1 seem to be taking up the most CPU, threads, and memory. What are they? How can I make my computer more efficient? Are these processess causing my computer to be so slow and freezy?
I have been experiencing the fan running at high rpm and the computer completely slowing down when there is slight pressure applied to the bottom of my macbook pro. I went on Activity Monitor and it shows kernel_task running at over 100% cpu usage. I have already tried resetting PRAM and SMC but those did not work.
I had my first leopard problem on my 1.67 15" powerbook last night. I lost bluetooth so I restarted, I went to the activity monitor and there was a kernel task eating up 152 mb of my ram. All updates are current and I have 2gb of ram. Any ideas as to what this action is doing. I also have a dual 2.4 g5 with 3.5 gb of ram(but no kernel task issues).
I've had my macbook pro repaired a few weeks ago (new battery and keyboard).. Ever since then every time I boot it its superslow ... + with high activity on kernel_task.. When I close the lid and open it after 5 seconds again the problem is gone.

In the memory tab in activity monitor, it shows kernel_task which takes up 440 MB. It takes a huge amount of my memory. Also, my macbook pro is running down. I believe that one of the reason for this is kernel task. How do I fix this?
When I open Activity Monitor, kernel_task is using approx 240 MB of real memory, and 67 of virtual. All I have open is Safari (and Activity Monitor)Seems like alot of real memory for one process.
A few hours ago, I noticed my MBP start hanging and generally processing very slow. Apps would freeze at random times, and generally a lot of odd behavior.
I checked the activity monitor to see what might be causing this. It turns out, the process "kernel_task" is using almost 100% of my CPU. It has stayed within the 70-100% range, and has yet to go down. I tried many things, including restarting my Mac many times, but it remains the same.
Does anyone know why "kernel_task" is taking up so much of my CPU? Is there a way to somehow "reset" the process to get it back to normal?
P.S. I attached a screenshot of the process in the Activity Monitor. You can view it here:
EDIT: I just want to add that I think the "kernel_task" might have started eating CPU when I stopped a RAR program in the middle of extracting an archive. I'm not 100% sure though that this is when the problem started.
start getting kernel panel in mavericks quite a few months agoended up taking to apple...diagnosed as hard drive issue, replaced hard-driveafter hard drive replaced, still getting kernel panics (various things including chrome)format and reinstall OS (Mavericks)took back to apple service provided, replaced hard-drive again.Upgraded to Yosemite however in mid 2010 iMac it really slowed things down. Had to take out third party ram because kept result in crashes that quickly lead to damaged sections on hard-drive so had to reintall OS. Only had 4Gb of original apple ram.due to sluggy performance of yosmite, recently (today) "downgraded" to mavericks.Install third party ram back into computer (now have 12 Gb)Experienced 2 kernal panics already. Can't work out what the issues is
This is pretty bare bones. Not much intsalled since "downgraded"to Mavericks. Log below

recently - perhaps after upgrading to 10.9.3 - I am experiencing kernel panics on my 15" MacBook Pro 2,3 GHz Intel Core i7 whenever I connect my external Western Digital My Book Essential hard drive. I have upgraded its firmware to the latest version I could find, v. 1025 - and thought this had fixed it, but it hasn't...

I am using Cisco's vpn client to connect to my work. It uses IPsec, UDP. Although I can connect to the VPN server at work, I can't access any other resources. I noticed that routing tables are not updated. I can continue to use internet and I think traffic is not being routed through the VPN connection at all. I tried adding a default route: route add default ip.vpn.at.office (ip.vpn.at.office is the static address of the work place vpn server) Doing this, I only lose my internet connection but do not get access to work place resources.
What/where is a good resource for learning how to edit HD video via FCE 4.0. I am having my difficulties and end up back in iMovie, but I made an investment in the FCE and want to learn to use it.
I recently installed the widget iStat Pro. When i did, i discovered that the (what i presume to be) drivers from my printer are using up all of my processes. In the processes tab, it can go anywhere from 90% to +100%. I have nothing in my login items but iTunes helper and absolutely nothing in the start items. I don't know what to do about this.
When I'm running mail my fan started continuously running on high. I search google and found out that mail was using close to %100 of the system resources.
I can not find out how to correct this issues. I'm using a gmail account via pop.
To reduce the signal to noise ratio,please do not respond to this post asking questions of why I want to do this or with opinions about the validity of the task.I have a mid-2010 MacBook Pro Core i5 and I am consistently enraged that a computer this powerful is always lurching along when I am trying to do multiple things at once.I would like to limit the amount of RAM/CPU available to applications on a systemwide basis.All mobile OSes institute this policy (except for Android and its runaway memory munching) and this is what makes those system react so quickly.I know about nice and freezer but these solutions require constant tweaking for each process run. I would like a solution that is applied to every process, systemwide, if that is possible.

I'm picking up two laptops next week and am wondering if there will be much of a performance difference between leapord and tiger. One Laptop will be a G4 1.33ghz with 1gb of ram. I hope for this to run the midi tracks to control lights on stage and the backing audio tracks(roughly 15 audio files running at once). The other will be a macbook pro 2.0ghz (core duo) with 2gb of ram. This will run the live VST synthesizers(no more than 2 at a time) through my sequencer (cubase or maybe a mac alternative). I'm thinking it would be easier to just have leapord on both machines but I may need to squeeze everything I can get out of the G4. Is their a performance difference or does one OS take more resources?
I have a new mac mini, 1gig ram, 2ghz processor, and finder is consistently using 65+ percent of cpu percentage, i checked my buddies computer and his finder uses 1%. Also my computer crawls and i assume this is the reason.
So I've been helping this guy do stuff with his mac (MBP 3,1, 2.4GHz dual-core, 2GB DDR2 RAM w/667 bus) and lately he's had a problem where his computer freezes totally and you have to reboot. I was working with him today and it froze while I had address book (which had stopped responding) and finder open. He always has a second screen (one of the big apple monitors that uses the video port, a USB, and a firewire 400) and an external Firewire 800 harddrive, with external power-source, for backup always plugged in.
The machine is only like 2 years old and he has over 70 GB left on his harddrive. Is it possible that always having the external monitor and external disk is draining resources and making the computer run slower? If this is the case, will this model MBP hold more than 2GB, and if it does, does it come with two 1GB modules, or one 2GB module? The next time I see him I'm gonna install MenuMeters to see if his resources are being used a lot with the stuff plugged in.
My friend was having some issues with an old mac of his, so he bought a new one. He said that when he connected the two macs to move files from the old one to the new one, something weird happened. Te new one found the processor and ram from the old one and used it as its own resources.
I have lost contact with this guy so i have no way to find out how this was done. I think he said he used a firewire cable between the two macs but am not sure
does anyone know how to do this? I dont think it was xgrid cause it worked with all programs and could see the processors in activity manager. Any help would be greatly appreciated.
Yes you read that right. Your brand spanking new MBP will use a 32-bit kernel as default.
You can force 64-bit kernel but some of your hardware will not be working.
So all that marketing crap about the benefits of 64-bit etc are all B.S.
I don't want a million threads about how this will not effect the running of 64 bit apps, etc. because it will. Your 64-bit app will run but it will not be able to address more than 4Gb of RAM.
There are also many more advantages to having a 64-bit kernel.
I have the 2.2 blacbook, 4gb ram, 320gb hdd. Now when I first bought my macbook, I did not use Illustrator or Photoshop CS3 (for both). Now 1.5 years in, I am using Illustrator and I noticed that when I am working on both (either at the same time, or with one program closed) I sometime get the message in Illustrator "Not enough memory" or "Not enough ram" or when I am saving an image for web and devices "an unknown error has occurred"
BUT if I use Illustrator and Photoshop CS3 (for both) on Vista via bootcamp none of these errors occur. I just don't want to imaging what will happen when I use CS4. Is this due to the way Leopard is setup? I am also looking to upgrade...So do you guys think the new macbook or macbook pros would be better? I mean, my current macbook is holding up well...but I just hate these errors. I prefer to work in Leopard than Vista.
(ex: Working with Core Data, Implementing Push Notification). Certain videos appear to download but when I try to play them, the download starts again. I have "downloaded" the same video 5 or 6 times, and it still won't play.
Other iTunes video downloads from iOS Development Resources work without any problems (ex: Ingredients of Great Apps).
Specifically: if I am in iTunes, and navigate to iTunes U, then select the iOS Development Videos category, I see a list of all the videos that are available. If I click the little "Get" button for many of the videos in the list, the download process seems to work perfectly (I see the progress of the download in the header section, and it all looks normal). However, as soon as the download is complete, the "Get" button reappears and the video listing looks just like all the other videos that have not yet been downloaded. If I attempt to play the video (select it, and click the Play button) the download starts all over again. I have found one video that actually downloaded, and can be played.
Is there a setting that controls this behavior? I haven't been able to find it.
