My MacBook Pro fan is running extremely fast after installing Lion.  Indexing is finished.  It keeps going at top speed even after the screen saver is on.  Anyone have a similar problem?


MacBook Pro, Mac OS X (10.7)

    I have the same problem on a MacBook C2D 2 GHz with 4 GB ram. Correct me if I'm wrong, but I think OX 10.7 should run on a 2,5 years old machine.

    Same thing for me. Early 2011 17" MacBook Pro and 8GB RAM. Running hot for the first time since I bought it and the battery drained very, very quickly.

     

    Haven't seen any remedies or reasons for this anywhere yet. If I find anything I'll come back and share...

    This command fixed my problem

     

    sudo launchctl unload -w /Library/LaunchDaemons/com.citrix.agadminservice.plist

    sudo launchctl unload -w /Library/LaunchDaemons/com.citrix.agadminservice.plist ???

    DONE IT!!! thank you!!

     

    can you explain what is was n why it was doing it? just out of interest?

  • Not_a_Number Level 1 Level 1 (0 points)

    Wouldn't it make sense to find out about that before? And maybe Apple could comment on this.

    I got the fix from that thread I posted above. I'm no expert but, it you

     

    Open finder

    On the bar above click GO, then Utilities

    Open the Terminal utility

    Then paste the command in and hit enter

    It will prompt you for your password so, enter it and press enter again.

     

    The process will stop and your fan will slow down after your computer cools down.

    I appreciate that the terminal fix seems to be working, but over at Ars Technica they state that some apps appear to quit but their processes remain running:

     

    'As if all of this isn't enough, Lion features one final application management twist. When an application is terminated in Lion, all the usual things appear to happen. If the running application indicator is enabled, the small dot will disappear from beneath the application's Dock icon. The application will no longer appear in the command-tab application switcher, or in Mission Control. You therefore conclude that this application's process has terminated.

    A quick trip to the Activity Monitor application or the "ps" command-line utility may dissuade you of that notion. Lion reserves the right to keep an application's process around just in case the user decides to relaunch it. Upon relaunch, the application appears to start up instantly—because it was never actually terminated, but was simply removed from all parts of the GUI normally occupied by running applications.'

     

    All of these processes are bound to cause the CPU to work and therefore produce heat. Might explain the poorer battery life some MacBook users are reporting.

    When the process was running away my battery died in an hour. I usually get 5 hours.

    The Terminal fix didn't work for me, but after taking a look in Activiy Monitor, I found that one of my applications (TimeLog) was taking up 100% of the CPU!! I didn't even know it was running (or trying to run)...

     

    After forcing it to quit through Activity Monitor, the heat/fan issue has gone way.

    Terminal fix worked for me too.  Thank You!
