    As topic says, after installing 10.10 after a few seconds the temps go totally haywire and the fans hit max, while nothing is happening just sitting in desktop, have to turn it off to not kill it. Anyone had this?

    Have you checked CPU usage just to make sure something is running at 100%?

    Ill try... but its a scary race against time :p as the laptop just goes ballistic!

    I did just do an upgrade ( as i have with nearly every other beta without too much trouble) but there is a very real chance there is some small thing it doesn't like... finding it how ever...

    I have the same problem. UserEventAgent is running at 114 % CPU. Any ideas?

    fixed

    I have a 2013 Retina 15.4" Macbook Pro and 2012 Retina MBP. Was having the same issue with UserEventAgent hogging up 117-140% CPU.

    The following worked for me to temporarily solve the issue. I nneded to get it solved as my battery lasted only 1.5 hrs due to high CPU use.

    Go to

    System/Library/LaunchAgents

    and "move" the following files out of the folder to any place safe.

    1. com.apple.UserEventAgent-LoginWindow.plist
    2. com.apple.UserEventAgent-Aqua.plist

    OSX will ask you for admin authentiction.

    Once done. Reboot and the HIGH CPU usage should be gone.

    I noticed that these are agents used to trigger important system drivers (as far as I know and I may be stupid) but so far it has not affected anything at all. System is running fine for the last 2 hrs.

    Just my two cents.

    If this screws up things for anyone, pretend you never read this. ;-)

    Thank you very much. My system was burning up. So far so good. :)

    Does this change anything with the super laggy and sluggish performance when dragging finder windows around on the desktop? its interesting because if you look at the activity monitor as you drag a window around, the _windowserver goes ******* on the cpu basically capping it and thereby creating the "lag".

    ctrl+shift+command+option+.

    Upload the sys diagnose zip file that will eventually appear in a new finder window to a bug report describing the problem at bugreporter.apple.com
