A process named "discoveryd" takes up to 97% of my CPU after the last Yosemite update in April 2015

Hello,
"Discoveryd" process takes up to 97% of my CPU and when I force it to quit, it appears again after a while. I attached the screenshot of my activity monitor.
Appreciate your help.

  • HT5858 How come i can't take video any more with my Ipad after the last update

    Howcome I can't take video anymore with my Ipad, after the last update

    What happens when you try to take videos ? In the Camera app you should be able to slide the Video / Photo / Square options so that Video option lines up with the yellow dot to their left - does that not work ?

  • Videos take a long time to open after the last quicktime update

    Hey guys
    Since I've downloaded the latest quicktime update videos are taking a very long time to open. They used to open instantly and now they take about 40 seconds (negligable difference if quicktime is already open or not).
    This is with a Powermac G4 1.25Ghz with 2GB RAM running 10.4.10 and all latest updates.
    Any suggestions on how to fix this?

    I'd suggest tracing system activity when this long runtime issue occurs, so you could know where this time is spent (db access ? etc) ... a plain SM50 call in parallel could do the trick if runtime is long enough !

  • After the 2.2 update my camera now takes crappy pictures

    after the 2.2 update my camera now takes crappy pictures. Is there a way to fix this? Before my Droid took great pictures not now. Help

    I have the original Motorola Droid, and my camera takes crappy pictures at a distance since the update. Images are very distorted. The camera takes a while to open. The phone now stalls when trying to locate and bring up a picture from the photo gallery. I will be getting the new Droid X in a few days, and I hope this phone does not have the same problem.

  • Garageband takes longer to load after the 5.2 update

    I've found that Garageband '08 does not load correctly with the 5.2 update. Apparently, Garageband takes up to a minute or longer to load During this time, the initialization window is active, the Finder acts somewhat slower, and Garageband is listed as unresponsive in the Dock. Usually, it loads after a long period of time, and works, but once I quit GB, it has to load up for a long time again. I've seen in other threads that external iSight cameras and other audio-related peripherals can by the cause of this, but I do not use my FireWire iSight camera with my MBP, nor do I have any external speakers and whatnot. Right now, I just have Office 2008 installed alongside the other applications.
    My question is what files, if any are conflicting with GB, should I look for? Or what would fix the problem as a whole? I understand that there were some other topics about this issue, but I don't think anyone has mentioned any tips in the past few days. I use GB a lot, so I could use some assistance. Any help would be appreciated.
    -MacUser

    Since I end up waiting at least 30 seconds to 2 minutes or so for GB to open, I need to figure out if I should just reinstall OS X with the restore disks and leave it at that until a fix arrives... I'd rather not though. Apple, come on, release a patch or some sort of fix for it!
    I did try to recreate the problem by using a FireWire iSight but even after doing that and fixing it, nothing changed. I saw in one thread that some people have GB working correctly for them while others do not, so surely there is something somewhere wreaking havoc with GB. This is really odd.

  • HT4623 After the iOS 7 update my camera does not operate correctly.  It will take about 5 photos then it becomes very sensitive, moving between "video & square".  I turn  it off & back on, it work for a second or two & lockout again.

    After updating my iPad my camera does not operate correctly. It will take about 5 photos then lockup. It also becomes very sensitive when I try to zoom in, it changes to "video or square".  I have to turn off for awhile then it repeats the same  malfunction, just lockup again.

  • Macbook takes longer time to launch & log in after 10.6.4 update

    After 10.6.4 update,
    my macbook took quite a long time to launch the log-in screen page.
    Not only that, upon logging in, the dock, icons & toolbars took long than usual to appear as well.
    Though, it's just a minor problem, but anyone else is experiencing this problem?

    I have experienced slow loading time even after a reboot with 10.6.4.
    Additionally, Flash programs are not loading in my Safari 5; experienced problems accessing my new phone upgrade options on the Verizon wireless website and some games will not load.
    Also when I mouse over drop down menus on the Verizon wireless website, the screen appears to bulge before returning to a "normal" view.
    I'm ready to backtrack to 10.6.3 and Safari 4!!!

  • Quicktime takes a lot of time to open after last Quicktime or iTunes update

    I have actually no big problems, but its a bit annoying that Quicktime Player takes a lot of time (maybe twice as before) for opening a Quicktime file (mp3 or video file, it doesnt matter).. I think this situation arised after the last Quicktime update or the update before this I dont know for sure. I think the last Quicktime update.. I am using the latest Quicktime which is 7.6 and its Tiger (10.4.11). When Quicktime Player is not opened, and its getting opened for the first time by clicking for instance on a mp3 file, it takes more then 10 seconds to open up, when I click the file Quicktime Player bounces normally as always but then the spinning rainbow beachball is shown for more then 10 seconds before the player window appears. There is no delay when I go open a mp3 from another mp3. The delay occurs only when Quicktime Player is not opened yet (quit/closed) and you click on a Quicktime file then the delay happens during the opening of the player.. Sometimes it doesnt even open the file I clicked, but only Quicktime Player so I have to click the same file again..
    What I tried is :
    deleted all Quicktime player preference files.. Didnt help
    removed all plugins from the Quicktime library.. Didnt help either
    What could the problem possibly be? What can I do to recover it except for installing my system all over again? Will Apple fix this problem with the next update?
    PS: I dont exclude that the latest iTunes update (8.1) can be a cause of this problem. Do you know if the iTunes update also changed/updated something regards Quicktime (Player)?

    Why is an Archive & Install not an option for you? It does NOT delete your applications or your settings, and is NOT the same as an Erase & Install which does.
    In my opinion it will be the only way to get your old G3 working properly again.
    How to Archive & Install:
    http://docs.info.apple.com/article.html?artnum=107120
    This document explains how to correctly reinstall a prior version of Mac OS X in the event that other troubleshooting does not resolve an issue:
    http://docs.info.apple.com/article.html?artnum=25404
    BUT: Don't install older versions of Mac OS than what comes with your computer:
    http://support.apple.com/kb/HT2186?viewlocale=en_US
    Will Apple fix this problem with the next update?
    For 99.9% of users there is no problem to fix.
    But before doing your archive and install, when did you last perform a bit of maintenance?
    Repairing permissions is important, and should always be carried out both before and after any software installation or update.
    Go to Disk Utility (this is in your Utilities Folder in your Application folder) and click on the icon of your hard disk (not the one with all the numbers).
    In First Aid, click on Repair Permissions.
    This only takes a minute or two in Tiger, but much longer in Leopard.
    Background information here:
    http://docs.info.apple.com/article.html?artnum=25751
    and here:
    http://docs.info.apple.com/article.html?artnum=302672
    An article on troubleshooting Permissions can be found here:
    http://support.apple.com/kb/HT2963
    By the way, you can ignore any messages about SUID or ACL file permissions, as explained here:
    http://support.apple.com/kb/TS1448?viewlocale=en_US
    If you were having any serious problems with your Mac you might as well complete the exercise by repairing your hard disk as well. You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair.
    Once that is complete reboot again from your usual start-up disk.

  • Too long printing process with Mail since last system update

    Since the last system update about a week ago, it takes forever for Mail to process an e-mail to the printer (about 30 seconds).  Most of the time, the emails only include text.
    This only happens with Mail.  I daily use FileMaker Pro, Excel, InDesign,... and only have this problem with Mail.
    My printer is a Xerox Phaser 6360 and I have a new iMac with an OS X V.10.8.3
    Can someone help ?
    Thank you

    Do you have any Mail plugins in the ~/Library/Mail/Bundles folder? Perhaps there is an incompatibility between them and Parental Controls?

    For the last few weeks, the iTunes store has been displayed with empty graphic rectangles (with a blue box containing a white question mark centered in the rectangles), bits of text, and some buttons. The page extends quite a ways, including what I assume would be all the links to all the music...
    If all you are trying to do is buy music, you can easily buy MP3s at any online music download store (e.g. amazon.com) and add them to your iTunes library.

  • Has anybody noticed that it takes longer to boot up since the last update on my iMac?

    It seems to me that bootup now takes extra time to complete on my 21" iMac since the last security update.  Is this real, or have I never noticed it before?
