Just recently my 13" Macbook Pro started to run very slowly. When I search something on google, the spinning wheel will pop up as my cursor and remain for about 30 seconds while I am unable to do or click on anything and if itunes is playing in the background then the song will stop abruptly. Everything eventually loads but its just a pain in the butt. Before this i was doing the exact same type of things with my computer and it handled them fine so i do not believe its an issue of RAM. THis happened to me once before and when I turned my computer back on it just got to the gray apple logo and would go no further, somehow my harddrive failed. Any information or help on this problem would be greatly appreciated.

    If you have more than ten or so files or folders on your Desktop, move them, temporarily at least, somewhere else in your home folder.

     

    If iCloud is enabled, disable it.

     

    Disconnect all wired peripherals except keyboard, mouse, and monitor, if applicable. Launch the usual set of applications you use when you notice the problem.

     

    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.

     

    If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.

     

    Select the CPU tab.

     

    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?

     

    Step 2

     

    Launch the Console application in the same way as above, and select “kernel.log” from the file list. Post the dozen or so most recent messages in the log — the text, please, not a screenshot.

     

    If there are runs of repeated messages, post only one example of each. Do not post many repetitions of the same message.

    Your boot drive is failing, or you have some other hardware fault. Back up all data immediately, then make a "Genius" appointment at an Apple Store to have the machine tested.

     

    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros (do this only if you know how to restore, and you have at least two independent backups.) Don’t erase the Lion recovery partition, if present.

    Certainly the I/O errors suggest a problem with hardware.

     

    The messages relating to AppleFSCompression are usually seen in different contexts, sometimes relating to third party software. However if a problem with hardware has impact on the file system, I guess that the messsages may appear on a relatively clean system.

    Can you tell me what in the world is going on with my computer!?!?!

     

    Process is Safari Web Content.  values:  me:  30.25  System:  4.86  Idle 65.17 

    Page outs:  664  Swap Used:  2.27 GB

     

    It is running extremely slow.  I am not only annoyed, but very concerned.  Thank you in advance for your help.

    For users who have no fear of Terminal, here's another good point of reference:
