    Guys, I upgraded to 10.6.8 and now I notice that during lite web browsing my fans spin up to 6K (on both) and the temperatures are what I believe to be normal.

    Is this a result of my upgrade? I know they were having issues with the Xserve and 90%+ on the CPU's.

    Thooughts??

    I'll have to check that when I get home from work.

    If your running Parallels that is the problem, there is a simple "fix" if that is your case. My temps went way up and fans were blasting but all is great now.

    If you're running parallels, get the update
    If you're not running parallels, then try this:
    1. take a screen shot of the dock (using command-shift-3 and/or grab
    cropped pdf screen shot so it was only the dock picture
    2. deleted the user>library>preferences>com.apple.dock.plist file (make sure you look in the user library, not the main library...)
    3. forced quit on dock (or just log out or reboot)
    4. new standard dock was created
    5. opened dock pdf and then rebuilt the dock like it was before
    problem solved

    Thanks so much for the advice, totally cured my high fan problem.My performance has also improved. I updated parallels and performed the dock reset.

    run the application "activity monitor" which is probably in your applications/utility folder

    sort by process name, and find "dock", click on it, then click the "quit process" red stop sign icon at the top.

    I'm not running parallels but I do have it installed.

    this is what I found running. prl_disp_service Owned by root

    running at 99% CPU usage.

    Once I force quit this then logout and log back in it seems to be fine. Thoughts on what this service is?

    On my machine (2011 Macbook Pro 10.6.8) Xcode 4, even without any projects open is using 200-300% of cpu (which I'm guessing is 2-3 full cpu's).
