AppleSpell.service running 100% of CPU and overheating

Hi, I have a 15'' MBP retina 2.6ghz running 10.8.2. For the past 24 hours, the CPU temperatures on my machine were running around 170-195 degress F. According to the Activity Monitor, a process called AppleSpell.service was at 101% of CPU. Once I quit, the temperatures dropped and battery life jumped. Two questions:
1) Probably being paranoid, but would there have been any damage to hardware after running at 185 degrees for a full day?
2) I've had this machine for a month and it wasn't a problem before. The only thing that changed on my machine over the last 24 hours was installing iTunes 11. Could this have triggered something faulty with AppleSpell.service?
Thanks

Your MBP ad heat sensors that will shut it down if it exceeds dangerous levels so that it will not commit Hari Kari.  The threshold I believe is 105c.
The download of an iTunes upgrade should have no affect on other software.

  • Dock consumes 100% of CPU and fan runs.  What to do?

    I have a 2010 MBP with SSD and VMWare (not Parallels).  Every so often, the dock cranks up to consume 100% of the CPU, and the fan runs.  The problem goes away when I reboot. I've tried quiting various applications, but it doesn't seem to make a difference (i.e. I cannot identify a rogue app that's causing this).  There are a lot of discussion threads on this problem with OS 10.6.8 and Parallels, but I'm running Lion 10.7.1 and VMWare (which I've shut down).
    Any others have this issue?  Ideas for solution?

  • AUDIODG.EXE hogging 80-100% of CPU and sound not working in Vista . . .

    I posted this on a Microsoft Answers Forum but none of the techs or people reading have been able to help so far.  I'm dying to get to the bottom of this:
    Here is my computer:
    MSI K8N Neo4 Platinum
    AMD Athlon 64 3000+
    2GB RAM
    XFX GEFORCE 6600 GT 128MB DDR3 DUAL DVI & TV OUT (PCI-E)
    200GB WD SATA HDD
    500GB WD HDD in external enclosure via USB2
    NEC ND-3520A 16X DVD±RW Dual Layer DVD Burner
    LG CD Burner
    I've been using Vista Home Premium successfully for some time.  Recently, not too long after I did a clean wipe of my OS, my audio would stop working.  The way it would happen is that everything would work fine until I started iTunes or another audio application and when I would hit play, things would lock up.
    Upon inspection of my system resources, I'm noticing that the audio platform for Vista, via the audiodg.exe, is using close to 100% of my CPU resources, even when the computer is making no sound at all.
    I've had a Sound Blaster Live! card in my computer for some time but I was not using it; I use the Realtek AC'97 audio drivers that are on my motherboard instead.  I thought that the conflict may be the computer wanting to recognize my Sound Blaster, so I took it out of my computer but the problem seems to be worse.
    Are there any BIOS setting that need to be adjusted for my sound to start working again?
    I'm very reliant on the audio processing power of my computer (I'm in the radio industry, part-time) and this is a huge drag on my productivity.
    Any tips would be much appreciated.
    REPLY #1:
    Thank you for using Microsoft Answers forum.  I suggest going to the manufacture of your sound card and download the latest drivers and install them.
    MY RESPONSE:
    Good suggestion.  The problem is this:
    I am running on-board audio.  I have an MSI K8N Neo4 Platinum motherboard which runs "Realtek ALC Series AC97 Audio Driver" and there is no version for Vista. They have a version for Windows 2K/XP and one for Windows XP 64bit.
    Should I use on of those and if not, then what?
    UPDATE (from me):
    I took a chance and found a Realtek AC'97 driver for Vista.
    http://drivers.softpedia.com/progDownload/Realtek-AC-97-Audio-Codec-Driver-Vista-6183-Beta-Download-18114.html
    I went to install it and the install hung.  So, I closed one of the install windows and then the InstallShield app continued like it was working.  So, I hit "Restart my computer".  Well, the reboot hung too.  So, I reset the PC manually.
    When the computer came back up, the sound worked.  Hard to tell if this will fix it for good but it's promising.  Chaotic.  Unpredictable.  Annoying.
    REPLY #2:
    Before you tried updating drivers, did you try rebooting 1st?
    I'm just trying to determine if rebooting your system is what resolved the issue - thank you
    UPDATE II (from me):
    My computer is behaving the same way it was before.  AUDIODG.EXE taking up 80-100% of my CPU and the sound not working.
    Any other ideas?

  • Passport battery drain -- 'Input Services' running at high CPU %

    This is the best phone I have ever owned -- size, physical keyboard, fantastic battery life (under normal circumstances) BUT every 2-3 weeks, it begins to misbehave.
    I'm not sure what the trigger is but the following happens:
    1. Top RHS of the phone gets very hot.
    2. Upon unlocking, the location services icon is often 'on' (before disappearing a few seconds later).
    3. Device monitor shows Input Services at high CPU percentage Eg: 25% or higher.
    4. Battery drains from full charge to empty in about 3 hours, irrespective of use. Charging takes hours, particularly via USB or car kit due to the high-rate of drain.
    I am not running any added apps and OS is updated to latest. The only fix is to backup the phone, restore factory settings and restore data.  Then 2-3 weeks later, problem repeats.
    I'm convinced 'Input Services' is the culprit -- but why???  Is this service related to the physical keyboard somehow?
    Any thoughts are appreciated. Thanks.

    Hello @all,
    Same problem here. Got my Passport 10 days ago.

  • Skype using 100% of CPU and hard disk resources, c...

    So, lately, I switched the hard drives in my computer to migrate from Windows XP and install Windows Vista to my machine, everything was going alright with my machine, until I decided to install Skype, as it's the main communications line with me and the internet, and I noticed it now takes up pretty much all of my CPU and hard disk resources when loading all of my contacts and messages after installation, but it finished loading them, and it still uses a high amount of my resources. Skype uses approximately 250MB of memory (Which is kind of high on a system like mine..), it maxes out the processor at around 95-100% utilization, and the hard drive light is on full, as I hear the read head spazzing out on the thing anyways. I was wondering, is this an issue with the latest version of Skype? I can't use older versions since Skype/Microsoft decommissioned them, and it won't even let me log in to them. Could someone possibly help me with this? 
    My machine specifications are as of follows if it has anything to do with the issue.:

  • In mail 8.2 if I click the template button the CPU start running at 150% CPU and WindowServer arrive to 20 GB and more of memory

    hello, after upgrade to Yosemite I have a problem with Mail/CPU.
    if I create a new email message everything is ok, but if I click the button at the top right (show template) on the message window, the CPU running at 130-150% and the VirtualServer memory start increasing up you 20 GB and more.
    If I close and reopen Mail (without closing the mail message) the CPU return to 130-150% but if I send or delete the message the CPU return to the standard value
    If I don't click the template button on the new message window the CPU works correctly.
    This thing cause slowdowns and unexpected logout of my imac, I contacted applecare twice and they told me to create a new user (first) and reinstall a fresh operating system (second). I have done both but the problem is not solved.
    I have also tried this (without results): Guide: How to solve Yosemite memory leaks and CPU usage
    Do you have any solution for may problem?
    imac 5K - 16 GB ram
    Yosemite 10.10.2
    Mail 8.2
    Thanks in advance

    I have that same problem on all my yosemite Mac´s too and no solution yet exept deleting your own templates.
    But if you need to use the templates for your business like i do this is not an "good" option
    I use this workaround at the moment until theres a fix
    You can copy our own templates in an existing nativ template folder apple mail uses. (Google knows where the folders are)
    (Or you can use another Mail program or a slow Apple Mail )

    Yes I did and in this instance the problem was solved.
    When it first started happening I figured that because of all my configuration changes resulting from the new drive that Spotlight indexes were updating or something similar.
    Probably all is fine but I'm noticing everything at the moment since I've made major changes to the MB Pro.

  • USB Print and Storage Center running 100% of cpu

    Macbook Pro 15 in. mid '09, 10.7.4, 8GB DRAM, 500HD.
    Occassionally, I get a very hot computer.  Running Activity Monitor indicates that the USB Print and Storage Center is running the CPU at 100% or in the high 90s. Since I'm not printing or even using USB printing, I haven't figured out what is causing this issue.  Any suggestions?

  • ITunes uses almost 100% of CPU and slows PC down

    Recently I decided to start using my iPod touch 4G again and downloaded the latest version of iTunes.
    Upon launch, iTunes acts normally until about 4-5 minutes of being open (just in idle). It then happily proceeds to use up 100% of my CPU load and slows my entire PC down to a halt, even once I've closed it (iTunes).
    I've tried re-installing it, downloading a different version, disconnecting from the internet, practically everything and yet the problem persists.
    My PC specs are as follows:
    Amd FX Piledriver 8-Core FX-8350 @ 4.0GHz
    Powercolour HD7990 Devil 13
    G-Skill 1866Mhz 16Gb memory
    OCZ Vector 128Gb HDD / WD Caviar Green 3TB
    So I can assure you, this is NOT hardware related.
    I've tried the following method with no results.
    1) Click Start and type "cmd" (without the quotes) DO NOT press enter or Ok yet.
    2) Right click "cmd" in the search results at the top of the start menu and select "Run as Administrator".
    3) In the command window, type "netsh" and press enter. (Without the quotes)
    4) In the next prompt, type "winsock" and press enter. (Without the quotes)
    5) In the next prompt, type "reset" and press enter. (Without the quotes)
    6) Reboot the PC. (Do not skip this step)
    I've also been through the list of conflicting software and have none of the mentioned.
    I'm running Windows 7 with the latest updates.
    I'm getting extremely frustrated now. ANY help would be appreciated.

    Sorry. I did a search, and a lot of threads came up. The one I chose, I thought, explained WHY it happened.
    Maybe you'd get answers more helpful to you, if you went throught the search results.
    Sorry I wasn't of any assistance.

  • I installed itunes 11. It takes 100% of cpu and GUI is not responsive for minutes at a time.  Keystrokes are lost in the search box because of this. This worked fine in previous release. I have 4300 albums and 70k  songs.

    I have an itunes library of 4000+ albums and 70k+ songs. Worked great until itunes 11 today. Now, when ever I go to the search field and type 1 character, I go to 100% CPU busy and all the other characters are lost. "itunes not responding" for a couple of minutes.  
    Also happens when I am importing a CD from physical media, and I switch to music and try and find another album. Gui becomes unresponsive and activity monitor ends up reporting "Itunes (not responding)".
    How go I go back to the working itunes?

    Thanks. That was it I don't know why it got changed during the upgrade to iTunes 11.
    However, it still takes 5-10 seconds for this menu to appear, with the cpu at 100% one core. Seems like iTunes should support multi-threaded/multi-core processing, especially for the GUI.

    Thanks. Short of the sort of "generic" suggestions of restaring your system, if you haven't, and repairing disk permissions and verifying the disk, I don't have any advice right now. I'll do some research and see if I can come across anything. Meanwhile, someone else may have an idea.
    Regards.

  • Firefox 3.6.3 & .4 uses 100% CPU and won't always close or open

    Firefox intermittently uses 100% of CPU and I have to manually turn off the computer. Firefox also does not start or finiosh correctly, the process is alive and I have to use Task Manager to end the process In the meantime I have installed IE7, as I cannot access internet banking with Firefox. Very disappointing as I have ben an enthusiastic user and promoter of FF.
    == This happened ==
    Every time Firefox opened
    == After upgrading to 3.6.3, and is no better with 3.6.4, despite deleting all add-ons

    I also have this problem which has been getting worse with recent successive updates of Firefox. As a long-time user and advocate, I am about ready to look for an alternative browser. Firefox will not close and exit properly, requiring direct cancellation through Task Manager; starts up very slowly (often 1 to 2 minutes); and frequently locks up the CPU with 100% of cycles while doing NOTHING; offers to restart crashed sessions, but cannot recover and reload those sessions; will not operate correctly while any other application accesses the internet, like uTorrent. Firefox is set to delete cookies, etc. whenever the session closes, sqlite database is vacuumed regularly, CCleaner regularly wipes remaining accretions, and disk is defragged. Currently running 3.5.5 but will NOT upgrade until this problem is solved since later builds report the same problems. I know several other users who have experienced the same problem and I can no longer automatically recommend Firefox to users and clients. Is anybody paying any attention to this problem? What is being done to address this fault? Why is there no response to the original poster? Is this really a support forum or just a way to preoccupy and distract the users who suffer this malfunction? Wireless 54Mbps connection. No Adobe Flash, QuickTime, MS Silverlight, etc. installed on this machine. Firefox 3.5.5 with the following add-ons:
    Aardvark 3.0
    Adblock Plus 1.2.1
    Adblock Plus: Element Hiding Helper 1.0.6
    Free Download Manager plugin 1.3.4
    Highlighter 0.1.4
    MR Tech Toolkit 6.0.4
    repagination 2006.4.5.1
    Save Complete 1.0.1
    Session Manager 0.6.8.3
    Tab Mix Plus 0.3.8.4
    Unhide Passwords 1.2.5.1
    User Agent Switcher 0.7.2
    Thanks for any help or suggestions.

  • IChatAgent takes more than 100% of CPU

    The iChatAgent takes more than 100% of CPU. It works normally for 10-15min with little CPU usage but then takes 100% of CPU and stays like that until I quit/kill the process. I tried waiting for hours to see it might go down is usage, but no, and the cpu fan remains on continuously.
    I simply use it for text based chatting, and have disabled audio, video,microphone etc, and still this behavior that I can't use it for more than 15min.
    Here is the iChat version: Version 5.0.3 (745)
    Macbook Pro/10.6.4/Intel Core i7
    I have tried removing ~/Library/preferences/com.apple.iChatAgent.plist as suggested elsewhere, and that hasn't helped either.

    Thanks again Ralph.
    No, I do not have any add-ons, just out-of-the-box ichat without any audio, video in use.
    At this stage unfortunately, I can't continue using iChat as it hogs up the CPU in less than 15min. And that I do not experience any problem with other chat-clients such as AIM or jabber, so switching over to those until there is a resolution.

  • DBSNMP consuming 100% of CPU

    I'm currently in the process of implementing Grid in our environment. I've created the repository database, installed the OMS and have deployed agents. Everything appears to be functioning. However, I began to notice that DBSNMP would connect to the targets, issue a metrics-gathering query which would consume 100% of CPU, and retain that consumption until I killed it (in some cases over an entire weekend). I'm running the OMS and repository database on Solaris 10 while the agents are running on 5.9. The Oracle versions are 10.2.0.3.
    Has anybody encountered this problem and if so, what did you do to solve it?
    Much appreciated.

    I haven't seen this issue..looks like it's a big problem if it consumes 100% of CPU.
    I'm just installing Grid Control on Solaris 10. I'm almost done with the 10.2.0.1 installation and i plan to upgrade GC to 10.2.0.3 next. You've had no problems upgrading, have you?
    Did you install the patches they recommend?
