MacBook is throttling CPU

Hi there,
i've got a MacBook Late07 and i discovered that if it runs under full load (encoding, etc.) the CPU becomes very hot. It goes up to 100°C very fast, then it lowers the CPU-frequency and voltage, to protect from overheating (Fan is blowing an maximum speed (6200rpm). Is this normal behaviour?
I can't believe that, because it means, that i can't reallly use my 2,2 GHz CPU over a longer time (longer than than a few seconds).
Thx for your help.

Well, then, that seems to be your answer. The computer is functioning normally and the temperature rises dramatically when you stress the CPU and GPU to maximum loads.
I don't see anything in what you've described thus far that suggests any problem. So, all I can add is that if this is an unsatisfactory answer for you that you take the computer in for repair to determine if there is a hardware issue. You can also try running the hardware diagnostics to see if anything pops up:
How to run hardware diagnostics for an Intel Mac
Boot from your original OS X Installer Disc One that came with your computer. After the chime press and hold down the "D" key until the diagnostic screen appears. Run the extended tests for a minimum of two or three hours. If any error messages appear note them down as you will need to report them to the service tech when you take the computer in for repair.
Some "common" error indicators:
SNS - sensor error
MEM - memory error
HDD - hard disk drive error
MOT - fan error

  • Using new Macbook as a CPU

    I am considering buying the new MacBook 13", to serve a dual purpose -- first to have a laptop to take when traveling, and second, to use to replace my current G4. I would use my current display and separate keyboard and, in essense, use the MacBook as a CPU.
    Has anyone done this? Are there any foreseeable problems?
    Thank you!
    susan

    To answer both of this question the answer is yes.
    You can do that.
    You can use the MacBook as a desktop replacement, by using your already had apple keyboard and mouse from your old G4.
    But you have to buy the adapter that match with you Monitor either that is VGA or DVI port.
    You could set the screen to mirror if you want the same exact screen as your macbook, or expand ir to use wide screen area from your MacBook to your external screen.
    Hope this help.
    And for Apple display look like the newer one use DVI connector.

  • Throttle CPU utilization during software updates

    Are there any settings to throttle CPU Utilization during software update installation on client computers?  I am deploying updates to test systems currently and noticed that the CPU utilization was being pegged at 100% during the install.  After
    the updates installed, the system returned to normal.

    Also note that ultimately, it is the Windows Update Agent that is installing the update(s) so it's not really within ConfigMgr's scope of control and would happen no matter what method you chose to use to update these systems with Windows Updates which
    leads me to believe these systems have perf issues to begin with. Are they VMs?

  • MacBook Pro System CPU Spikes When Unplugged

    Upgraded to Mavericks a few days ago and,whenever I unplug my MacBook Pro 13" (Early 2011 - 2.3GHz Intel Core i5 - 16GB RAM 1333MHz) and run just on the battery, my system CPU usage goes through the roof which results in my Mac running/responding very slowly and buggy.
    However, looking at the iStat widget on my dashboard, it's reporting that my CPU isn't running hot nor does my MacBook Pro feel hot at all. It's also showing that I still have 10GB of RAM free.
    As expected, once my magsafe is reattached to my laptop and plugged back in, the system CPU returns to a normal level. In Activity Monitor, it shows kernel_task as being the culprit.
    I queried the log as suggested by Linc and TextEdit had something for me:
    Dec 10 15:51:31 My-MBP kernel[0] <Debug>: Process Setup Assistant [307] disabling system-wide I/O Throttling
    Anyone have any idea what this could be? Seems like it should be a simple software config but I just don't know.
    Additionally, I also ran EtreCheck. These are the results when it's running unplugged:

    Does anyone have any ideas on why this is happening or are experiencing anything similar? I can't for the life of me figure out if it's a Mavericks issue or if it's a hardware issue.  Any advice would be much appreciated! Thanks!

    You're not going to believe this but I just now found a working solution!!!
    Thanks to the talents of a man named, Rhys Oxenhams, and his flawless tutorial, eveything's running normally now!
    BEFORE READING ON...make sure you backup all of you data!  I take no responsibility for anything bad that happens to your machine.  I'm providing this information because it worked for me. There's no guarantee it will work on your system.  TAKE ALL NECESSARY PRECAUTIONS BEFORE READING ON and BACKUP YOUR DATA IMMEDIATELY.
    Here's what you need to do:
    1. In the Finder menu bar, click on Go and select Computer. 2. In the window that comes up, double-click your computer's HD. For me, it's Macintosh HD. 3. From there, click on System > Library > Extensions. 4. Now look for a file called IOPlatformPluginFamily.kext. 5. Right-click on IOPlatformPluginFamily.kext and choose Show Package Contents. 6. In that new window that comes up, click on Contents > Plugins and locate ACPI_SMC_PlatformPlugin.kext. 7. Just like in step 5, right-click on ACPI_SMC_PlatformPlugin.kext and choose Show Package Contents. 8. Just like in step 6, in that new window that comes up, click on Contents > Resources and locate your Model Identifer.
         • In case you don't know what your Model ID is, click on the  in the top left of the screen and choose About This Mac     • In the window that comes up, click on More Info...     • In the next window that comes up, click on System Report     • In the very first screen, towards the top, locate the entry Model Identifier          - Write this info down on a piece of paper. You will need it. In my case, I wrote down MacBookPro8,1 9. Back in the Resources folder, locate the .plist file that has your model identifier. In my case, it was MacBookPro8,1.plist 10. You're not going to delete that file but instead move it to a differnt folder inside your home folder--doesn't matter which folder, just put it somewhere inside your home folder. 11. Restart your machine and you are good to go!
    Let me know how it turns out for you.  REMINDER: Backup your data before doing this!

    How i can fix this problem?
    Note that: this summer I have changed my logic board to a new one and since then i never had any problem. The only this is that i'm having a warning for service battery which i think is not the issue.

    Remove those kernel extensions and test again. They are not part of Mac OS X, you added them.
    If you do not know how to remove them, contact the manufacturer.
    If you still cannot figure it out, visit the genius bar (FREE with appointment).
    They will:
    make sure you have adequate Backups (which is two copies for this exercise).
    erase your hard drive (which deletes everything and has no way to get it back, hence the two Backups).
    Re-Install Mac OS X from original sources.
    Restore your user files.
    If that stops the panics, the problem was in the extensions you added.

  • 2007 Macbook Pro having CPU problems

    My macbook pro has been acting weird recently. It's been running slower, and things have been happening like...
    When i watch Youtube videos sometimes, when i try to fullscreen the video, the computer takes a long time to do it sometimes and other times the computer will log out completely.
    I'm a musician, and I'm trying to use Pro Tools, but even with everything closed and only one instrument open on Pro Tools, i'll get CPU overload error messages.
    I have 2GB of RAM which should be enough to run Pro Tools decently.
    I have 18 GB of space free on my hard drive.
    I downloaded SMART Utility and it said my hard drive is fine.
    Any ideas?
    Thanks,
    TJ

    I suspect your CPU is fine however you need to increase your HD storage. Mac's need a minimum of 10-15% of the HD available at all times to run well. For example if you had a 250GB HD you would need a minimum of 25-37.5GB available. What tends to take up lots of space is media (music, video & photographs) if you off load these onto an external HD that will help.
    Also 2GB of RAM is a very minimal amount. Run your computer normally then open Activity Monitor (Applications - Utilities - Activity Monitor), then click the *System Memory* tab. If your computer has around 500MB or less FREE RAM then you need a RAM upgrade too. In short this would mean your system is starved for RAM.
    Finally you may have unwanted or unnecessary apps opening at login. To check and remove open System Preferences - Accounts - Highlight your account - Login Items - then select the apps you want to remove from login and click the - symbol at the bottom of the box.

  • 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.

  • WVC80N software throttles CPU to 100%

    Hello,
    Just recently purchased the WVC80N and installed the video monitoring software.
    Can someone tell me why this software is throttling the CPU usage to 100%?
    It causes my computer to slowdown when I have this software opened.  Any fix for this?
    Thank you very much for your help.

    Does the computer operate normally if you use the camera WVC80N without utility? As well as you can try the following steps:
    # With Camera utility running on the Computer right click on the Task Bar and select “Task Manager” from the popup menu.
    # In the box there you will be able to see camera utility running.. Right click on that program and select “Go to Process” option from the menu…
    # It will take you to the Processes tab where you will be able to see the usage of the utility then once again right click over that and select “Set Priority” option and select it as Normal…
    After doing, check the status…

  • W520 not throttling CPU on battery with WLAN active

    I've been running some new benchmark tests using PCMARK7 this weekend. Normally my battery performance numbers are around 50% of the AC numbers when the system is connected to the wired LAN. The benchmark program utilizes the NVIDIA eGPU so throttling on the battery is expected. However, I reran the benchmark with the WLAN active and my scores on the battery were on AC, 4488;  On Battery, 4370!!! This was repeatable and not a fluke reading. I'm running BIOS 1.37, but I don't recall any changes in the CPU throttling area. Anyone else see this?

    I posted this procedure over a month ago in response to the "stuck CPU" on battery issue. 1.5GHz on battery is not normal. You should be able to achieve maximum clock frequency when MAXTURBO (not really TurboBoost) is set in the system settings for the battery section of the power profile. I regularly monitor 2.3 GHz on my system when the application(s) require it to do so (SpeedStep) when on battery. TurboBoost shows 3.4 GHz when on AC. 
    CMOS reset procedure:
    There used to be a procedure with older ThinkPad systems to reset the CMOS which was to both remove the battery AND to then depress the power on button 10 times (5 sec intervals between). I did both on my W520 (battery was out for 5 min), replaced the battery and plugged the system back into the AC. Viola, TurboBoost restored on AC, SpeedStep works now on Battery, HDD spin down now works on AC as well.BIOS level is 1.26
    Others have reported sucess with this procedure. I've no Idea why it should be needed on a new system, but apparently something is not setup correctly.

  • Macbook Pro Retina CPU Overheating when doing simple tasks?

    I've had my Macbook Pro w/ Retina since July 2012 and for about a month now (starting in November) the CPU Die - Digital has been getting EXTREMELY overheated. It has gotten up to 210 degrees F which is way past the damaging level of CPU but the real kicker is that it happens when I have a few tabs open in safari and a couple other minor programs open (Mail, Finder, App Store, Skype, iTunes). It's not like I'm running Skyrim, LoL, and Starcraft while running background tasks in Fincal Cut X and Motion V?? I mean I have 16GB of ram and only 5 or 6 of it is in use so it's not a problem with multitasking and processing power also shouldn't pose much of a threat for a few tabs in a browser and some low usage programs. I use iStat Menu's and I took a screenshot just now of it in the 180's when it was recently in the 190's. I also checked the disk utility and I can't see anything in the CPU usage that would make it work that hard.
    My questions are am I doing something wrong? Is there something I'm missing? Is my laptop defective and in need of refurbishing using Apple Care? Is this happening to anyone else?
    Thank you in advance.

    Turn off Skype and see if that has any affect.  Skype is is a notorious heat generator.
    Did you check Activity Monitor?
    Ciao.

  • Macbook pro 13" CPU A Diode temperature

    Hi all,
    I have recentlypurchased MBP13 inches (Intel Core i5 2.4 ghz, 500 G HDD, Internationalkb). I observed a difference in CPU heating behaviour compared to mypreviously used MBP 15" (2008 version).
    So I did the following test:
    1. CPU Temperature after 10 minutes idle (no activity except hardware monitor; user load 1-3% as measured by istat pro) :
    observations:
    CPU A temp diode: 42 degree C.
    CPU core 1: 40 deg C
    CPU core 2: 41 deg C
    CPU core 3: 40 deg C
    CPU core 4: 41 deg C
    2. CPU temperature after 10 minutes of constant intense CPU activity ( 100% CPU load) given on both cores of the CPU
    (by typing command in two terminal windows: yes > /dev/null)
    CPU A temp diode : 93 degree C.
    CPU core 1: 99 deg C
    CPU core 2: 99 deg C
    CPU core 3: 95 deg C
    CPU core 4: 98 deg C
    I have got two questions:
    1. Is this a normal behaviour of i5 CPU heating ?
    2. Why does the hardware monitor show 4 cores of CPU when in fact Intel i5 is a dual core processor ?
    Thanks

    Well, I talked to Apple support and tried to find out whether my observed temperature ranges vs CPU load were normal. Surprisingly, they told me that they haven't got any publicly available information on this phenomenon. 
    I have also inserted a plot of temperature rise vs CPU load here.
    So it sounded like Apple does not want to come transparent about this issue with their customers. They only advised me to contact the nearest service center and see what is their opinion. Now in the absence of any precise and standard information about temperature ranges, I don't know what would be the basis of opinion from service center.
    @pixelized - I suppose i7 overheating is increasingly discussed. But mine is i5. I guess the temperature rise vs CPU load should be different between the two processors. I have never observed temperatures like 120 C, even after 10 mins of 100% CPU load on both cores or by watching videos. Ambient room temperature was 18C in my case.
    If anyone has obtained observations of temperature rise on i5, I would appreciate if you share them here.

  • ITunes Throttles CPU to 99% Usage

    Whenever I start iTunes, my new Gateway desktop's fan roars and blows hot air like a jet engine. Opening the Task Manager reveals that the iTunes process is running at 99%.
    This continues until all podcasts have been updated. Then iTunes drops down to a 1% or 2% of CPU usage.
    I am running a Intel Core Duo 2.8 GHz with Windows XP Media Center. My internet connection runs through an anonymizer proxy server.
    Anyone have thoughts on what is going wrong with my software?

    The problem is that Apple just don't know how to
    write Windows software.
    I won't argue with you there, although I'd add that from what I've seen, they don't know how to write very good Mac software either.
    The issue is simply Apple assinging too high a task
    priority to the update process and it overridges
    everything else.
    But I will argue with you there, because this is simply untrue. For example, my PC does not exhibit this problem. No CPU choking whatsoever. Not during playback, not while updating podcasts, zilch.
    I suspect that your CPU is being stuck high because iTunes is going into a loop state when some other process is blocking access to some file, like, say, an anti-virus process would do.
    One thing iTunes (stupidly) seems to do a whole lot is to continually close and reopen files. For certain overzealous file monitoring and scanning programs (anti-virus, anti-malware, etc), closing a file means that the anti-virus program will come along and open it in read mode, in order to scan it for bad things. If iTunes then comes along and tries to open it again in write mode, iTunes would get halted by the OS, until the anti-virus releases the file and write mode can be granted.
    The only solution I know of would be to find the offending scanning program and temporarily disable it, or at least make it wait a bit before trying to scan recently closed files. Or switch to a less aggressive program.
    I also add that we have seen this exact sort of issue in relation to certain anti-virus programs and iTunes, such as the "iTunes takes forever to shut down" bug, which is caused by an anti-virus program interfering with iTunes trying to write out the database after being closed. I've also seen it with other programs, such as uTorrent, which in some cases had issues with Google Desktop, since uTorrent had a "feature" that caused it to cycle all open files to closed and open again, every 5 minutes or so. Google Desktop would see the file close and attempt to index it, which honked up uTorrent trying to reopen it, which gave a nasty error and shutdown of the torrent download. It's just a bad idea for programs, in general, to close files when they know they are going to open them again shortly, and programs that do it tend to have relationship issues with other programs. iTunes has this issue a lot.

  • Macbook pro 13" cpu 320%

    i dont know what happened to my mac but now everytime i turn it on the fan starts to run too fast and the cpu goes over 320%, first i was able to work with it but everything was super slow, now i cant do anything i just can go on the recover menu and try to repair the hdd but i cant , i dont want to lose my data
    help please

    Well, I talked to Apple support and tried to find out whether my observed temperature ranges vs CPU load were normal. Surprisingly, they told me that they haven't got any publicly available information on this phenomenon. 
    I have also inserted a plot of temperature rise vs CPU load here.
    So it sounded like Apple does not want to come transparent about this issue with their customers. They only advised me to contact the nearest service center and see what is their opinion. Now in the absence of any precise and standard information about temperature ranges, I don't know what would be the basis of opinion from service center.
    @pixelized - I suppose i7 overheating is increasingly discussed. But mine is i5. I guess the temperature rise vs CPU load should be different between the two processors. I have never observed temperatures like 120 C, even after 10 mins of 100% CPU load on both cores or by watching videos. Ambient room temperature was 18C in my case.
    If anyone has obtained observations of temperature rise on i5, I would appreciate if you share them here.

  • Mid-2009 macbook pro high cpu temp ( 100C) after every cold boot

    Hi everyone,
    Every time I cold-boot my MBP, the CPU temperature sky rockets to 100C within 3 minutes at idle with the fans barely kicking in until that point. The activity monitor shows 97% idle with no major processes running and this issue is reproducible every time I turn on the computer. However, if I immediately reboot the computer (warm boot), the computer runs normally (~70C CPU temp, fans @ 2000 rpm). If I do a SMC reset, the computer boots normally for the next immediate single cold boot but symptoms return thereafter. The only way to prevent the high CPU temperatures is to do a SMC reset before ever cold boot.
    I'm wondering if someone else has had these symptoms with their laptop and how they fixed it. The system is still under apple care and the symptoms are reproducible but I'd rather not bring it in as this is my daily-use machine.
