I am running Mountain Lion 10.8.2 on a mid-2010 MBP 2.4 GHz Core i5 with 8GB Ram and nearly 20% free HDD space. Why is it running so slow? I have cleaned in and scanned it with Onyx and sophos and run maintenance scripts. Any advice? Is my computer simply too old to handle Mountain Lion at a reasonable speed or is something else going on?


Thank you kindly for any advice you may have on the matter.

MacBook Pro, OS X Mountain Lion (10.8.2), Intel Core i5 mid-2010 MBP 6,2

    You should be able to run ML with your model and RAM without any slow-down at all.


    Take a look over ds store's excellent user tip - Why is my computer slow?


    If you see anything there that's applicable, you may be able to 'speed' your computer up a bit.


    And let OS X do it's own maintenance - Onyx and Sophos aren't really necessary and deleting some of the caches might actually slow you down even further.

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


    One possible cause of a slow user interface is a large number of image or video files on the Desktop with preview icons. If you have more than a dozen or so such files, move them to another folder.


    Otherwise, 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.

    I'm noticing this too.  I have a mid-2010 MacBook Pro 2.4 Ghz i5 and after I got Mountain Lion installed on it (a fresh install where everything was deleted and manually added back piece by piece), everything just felt a little more slow and non-responsive.  One of the the real annoying things is that when I connect a firewire hard drive with a lot of video files, it takes a long time to go in and out of folders to see the directory refresh.  I'm debating on going back to 10.7 Lion if possible, I don't recall any speed issues with that. 


    So far I've only just done the suggestion in this thread to move all the Desktop files to a diff folder (I threw them in Downloads). I had a bunch of files on my desktop. Let's see if that helps. Otherwise, I'll explore some of the tips that have been brought up in this thread. 


    But with the slow directory reading, I know that has nothing to do with the desktop files because that's on a different partition install of Mountain Lion that doesn't even have Filevault on and is still slow.
