Hi, I bought this macbook pro 15"last year. I downloaded the new Mountain Lion a couple months back. Nowaways the Macbook runs very slow, with little memory left even I run only Firefox and iFile.


I have run memtest and found it to be ok. I have downloaded Sophos Anti-virus to scan and found it to be ok. I had even downloaded and used Mackeeper but to no help. I have since deleted Mackeeper when I was told that it's an iffy software.


Please help. I see the rainbow ball more often than I used to these days.

MacBook Pro (15-inch Late 2011), OS X Mountain Lion (10.8.2)

    If you only have the standard 4GB I recommend upgrading your RAM to 8 or even 16GB.


    Make sure you uninstalled MacKeeper properly


    The antivirus you have is probably not needed as Mac OS doesn't get viruses unless you basically download one on purpose. Not sure what the one you mentioned does but if it runs in the background I would definitely remove it as it is doing more harm than good.


    If you make a new user account, log in to only that account, does it run slowly on that?

    See ds store's excellent user tip...


    Why is my computer slow?


    ...if you can't find a 'fix' to your problem there, call back.

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


    Take these steps 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.


    ☞ 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


    You must be logged in as an administrator to carry out this step.


    Launch the Console application in the same way as above. 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.


    Post the 50 or so most recent messages in the log — the text, please, not a screenshot.


    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 a message.

    Important: Some personal information, such as your name, may appear in the log. Edit it out before posting.
