Q: Kernel Task is using CPU and slowing down MacBook

Hiya, I've been experiencing problems with Kernal Task running at over 1GB, and Chrome running at 900mb, tried switching to Firefox which caused a simiar problem, this was repeated with safari opera etc, do I need more RAM? or is there a better fix for this problem?

A few suggestions for you

  1. You probably need more RAM, especially if you are using virtualization software
  2. I’d get rid of
    1. Chrome
    2. the com.cycling74 driver (frequent flyer on this discussion)
    3. the google keystone agent (another frequent flyer. Known for slowing things down by frequent phoning home. The good folks at Google have a definite talent for writing software that does not play well with Mavericks.) HOWTO: Remove Google Software Update on Mac OS X - Raam Dev
  3. the kodak stuff can’t be good.
  4. in general you have a lot of background processes going on, all of which are running all the time, using up processor and memory resources, and most of which don’t actually do anything useful anyway.
  5. these three need to be fixed:
    1.     [failed]    com.apple.wdhelper.plist
    2.     [failed]    com.apple.coreservices.appleid.authentication.plist
    3.     [failed]    com.apple.rcd.plist

Boot into your recovery partition (restart, hold down ⌘R until you see the Apple logo), and use Disk Utility to repair your hard drive. Repair permissions too while you're there. If that doesn’t work, reinstall Mavericks over your current installation. If that doesn’t work, do a clean reinstall (and don’t reinstall all the background processes you don’t need).

    As to the others:

    start a new thread. If you want the participants in this thread to find you fast also put the link to the new thread here.

    Give details in the next thread about what you did with CleanMyMac: if you did nothing else than cleaning caches, you may uninstall it completely and go on after restart. Otherwise it is now being advised to format your drive, install OSX, and reinstall apps you need, and transfer user data by hand (not from TM). CMM kills your system for goos.

    And uninstall iCleanMemory: it is counterproductive to Mavericks, and badly programmed.

    General advise: never download apps from sites as Softonics, Macupdate,  Cnet (download.com) etcetera: they manipulate the installer to give access, and/or generate adware and so on.
