Since I've done the upgrade to Mac OS X 10.8.3 my Mac has some problems and I would like to know If somebody else has my same problems and how to solve them. First of all, "Mission Control" seems to work slower, I mean it works, but when I "activate" Mission Control it works intermittently. Generally my Mac seems to be slower. I've tried to reinstall the operating system, but I haven't noticed improvements.

The operating temperature of my Mac now is on 60 degrees, before it was on 45-50 degrees.

MacBook Pro (13-inch, Mid 2012), OS X Mountain Lion (10.8.3)

    Try uninstlling any third-party programs that invade the system. Since you mention monitoring your system temp, do you have iStat or something else showing your temperature. That may be giving you the problems you see.

    1. how much ram do you have?

    2. have you tried repairing your hard disk, repairing permissions, a safe boot, a new test user account?

    3. how full is your hard disk?

  • Cerro595 Level 1 Level 1

    1.I have 4GB

    2. Yes, I've tried all that you said. No improvements

    Along with the other suggestions, make sure your startup disk is your main volume (e.g. Macintosh HD). Go into System Preferences / Startup Disk. Check Spotlight and make sure any external drives or internal partitions you don't want to scan are listed in System Preferences / Spotlight / Privacy.

    Do you mean that I have to uninstall all my applications? And to reset all my Hard-disk?

    I have installed SmcFanControl. It might be a problem?

  • arthur Level 5 Level 5

    You could take a look at Applications > Utilities > Activity Monitor and see if SmcFanControl is taking up an excessive amount of processor time.

    That should be enough ram unless you are running something extremely memory intensive, like high end video processing.

    You didn't say how full your HD was.

  • Cerro595 Level 1 Level 1

    I have almost 300 GB free on 500GB.

    This program,SmcFanControl uses only 9.7MB of Ram.

    I've thought that it might be a hardware problem. So I've done th Apple Hardware Test and everything was fine. I don't understand which could be the problem. Is very annoying to see "Mission Control" working intermittently and seeing how is slow my Mac when I slide between desks

    First, back up all data immediately, as your boot drive might be failing.


    There are a few other possible causes of generalized slow performance that you can rule out easily.


    • If you have many image or video files on the Desktop with preview icons, move them to another folder.
    • If applicable, uncheck all boxes in the iCloud preference pane.
    • Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.


    Otherwise, take the steps below when you notice the slowdown.


    Step 1


    Launch the Activity Monitor application in any of the following ways:


    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)


    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.


    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.


    Select the CPU tab of the Activity Monitor window.


    Select All Processes from the menu in the toolbar, if not already selected.


    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.


    Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?


    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)


    Step 2


    If you have more than one user account, you must be logged in as an administrator to carry out this step.


    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select

    View Show Log List

    from the menu bar.


    Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.


    When posting a log extract, be selective. Don't post more than is requested.

    Please do not indiscriminately dump thousands of lines from the log into this discussion.

    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

    Maybe I've done something wrong


    I hope I done everything well.

    For the moment, thank you.

    Step 1?

  • Cerro595 Level 1 Level 1

    For most of the time, the CPU is used by Kernel Task and  Program rendering by Google Chrome.

    User: 5%

    System: almost 5%

    Idle: 90 %

    Page Outs: 0 byte

    Swap Used: 110 MB

    Reads in\sec:4  Kbytes

    Writes in\sec931 Kbytes

    I've read these values.

    Can you help me with something,please?

    I'm really getting crazy...
