What does com.apple.cts.plugin do? It seems to be causing high CPU consumption by UserEventAgent

I have been having some trouble over the last couple of days with UserEventAgent process. It constantly consumes over 100% CPU. This of course results in obvious problems of the unit getting really hot, high CPU fan speed and faster battery drain.
While investigating the root cause, I removed each of the plugins (located at /System/Library/UserEventPlugins/) one by one and restarted the UserEventAgent process (if you force quit the process, it restarts) and each time, observed the impact on CPU consumption.
After a while, I was able to zero down on "com.apple.cts.plugin". If I removed this file from the plugins folder and forced UserEventAgent to restart, my CPU usage went back to normal with no excess heat or high-speed fan.
While it seems to solve my problem, I am left wondering what this plugin really does and if by not having it I am putting my system at risk.
Any help would be appreciated.

I learnt this the hard-way as well. I am not too sure but probably it has something to do with cerification authority or something like that. BTW I am looking for the answer as well.

  • What is com.apple.WebKit.Plugin.64 and how do I close it to install Flash Player?

    I am trying to update my Flash Player.  During the install process it says I need to close the following program:  com.apple.WebKit.Plugin.64  I have no idea what this is or how to close it.  I am running Safari 8.0.2 in OS X Yosemite.  Any help would be appreciated.  Thanks!

    i too was trying to update adobe and it kept stopping, saying i needed to close
    com.apple.webkit.plugin.64. but i had no idea where that was.  so i opened the activity monitor and found it.  it said it was opened in safari, under our guest account.  i had closed safari under my user name, but didn't realize it was still opened under our guest acct.  once i closed it there, i retried the installation, and i am happy to report it finished it with ease.
    so i would say to try and make sure safari is closed for all account users using your computer!!
    good luck!!

  • What does an apple symbol with a line thru it mean

    what does an apple symbol with a line thru it mean? it also has a ciculiar thing like its downloading but never moves and always stays lite

    robynlwitheridge
    What version of Premiere Elements are you using and on what computer operating system is it running?
    From your description "little circle with a line in it", that sound like a symbol when you are trying to do a cannot do operation.
    What exactly are you doing in your edit activities when you see this circle with a line in it? Is it at the end of the mouse cursor?
    Can you post a screenshot of it?
    If my first impression of what this is happens to be correct, then "How do I get rid of it?" answer comes from
    a. defining what you want to do
    and
    b. correcting any mis-steps you are taking in doing that

  • What does the apple sign mean when sometimes it shows ?

    What does the apple logo mean when sometimes i turn it on it just pops up and goes back to normal??

    Ayip,
    The Apple logo appearing on your iPod nano is your nano's start-up icon. Normally, when you turn off your iPod nano, you are really putting it into a deep or semi-deep sleep, where it is ready to turn on at the push of a button and resume where you left off in your Now Playing list.
    If, however, you leave your iPod in a sleep mode for some time , it will shut down. To turn it on again, you'll need to hit the center button (deep and semi-deep will wake up with any button press). When turning the iPod on from a shut down state, it will display the Apple logo while loading your music iPod software.
    Hope this helps!
    Sincerely,
    -FD

    Try the following to fix:

    - Also try DFU mode after try recovery mode

    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Com.apple.quicktime.plugin.preferences.plist

    My Dad's Safari 5.1 keeps on wanting to open PDFs using the QuickTime plugin. If we remove com.apple.quicktime.plugin.preferences.plist, and start Safari, it recreates the file with the PDF mime type set to true. If we manually change it to false, and start Safari, it no longer uses QuickTime to display the PDF, but some time later, the plist has changed back to true. So far we have not got to the bottom of why the plist keeps changing.
    On my Macs, after removing the plist, when it gets recreated, it is false. I did a clean install on my Macs, whereas my Dad upgraded from Snow Leopard. I don't really want to tell him to clean install !

    For general advice see Troubleshooting issues with iTunes for Windows updates.
    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it, which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.

  • I understand that when using Numbers/Pages - an up-arrow on a document means that the file is still to be uploaded to the cloud, what does a down arrow mean? It seems the document can't be accessed until the arrow clears.

    I understand that when using Numbers/Pages - an up-arrow on a document means that the file is still to be uploaded to the cloud, what does a down arrow mean? It seems the document can't be accessed until the arrow clears.

    I believe what it's supposed to mean is that some changes were made to the document on another device, and those changes were saved back to the cloud.  Now you've opened iWork on a different device to access that document - it compares the document you've got locally with the one in the could, sees some recent changes and downloads them.
    What gets me is why this sometimes happens even when I've not made any changes to a document from another device.

  • Does debug ip OSPF adjacency will cause high CPU

    Hello All,
    We are finding a OSPF flapping issue on Cisco 3750x switches. To isolate the issue TAC has suggested "debug ip ospf adj"
    Does this command will cause high CPU utilization?
    There are 12 OSPF neighbours connected to that switch and we have the hello interval of 1 second.
    Any of your help would be appreciable.
    Regards,
    Thiyagu

    It may do... But unlikely. There is always a risk with debug commands that have large output. Especially that you have hello intervals set to 1 second. I would advise to do out of hours if necessary to mitigate risks of impacting production.
    What version of ios are you on and show the output of 'show proc cpu sorted'
    I have had a similar experience and multicast was the problem. It was high CPU and dropping ospf adjacencies. We downgraded to 12.2 55 SE 8
    It helped the problem for CPU utilisation but didn't fix it. Since then we are using 6509Es in VSS

  • Kernel Panic issue -- What's com.apple.GeForce got to do with this?

    Hi all,
    Been experiencing this a lot lately, those dreaded Kernel Panic messages that ask you to restart the computer, complete with the depressing darkened screen in the background. The tech details below. Hope someone at Apple can help too.
    What happens that leads up to it? Can't see a pattern, sadly. Sometimes I'm just not doing anything on the iMac, and no applications are running, and it goes into Kernel Panic. Other times I'm using an application, and halfway through, Kernel Panic. No particular application too.
    Any ideas? Anybody?
