Any thoughts on my macbook running slow. This is a refurb from 2011 that I purchased several months ago. It was running fine at first but mail and safari are both running slow on and off. It was running lion and I just down loaded mountain lion yesterday. I also down loaded bitdefender it found 2 problems and then I ran a scan on the entire system and it says the mac is clean. Safari continues to lock up and lag. Any help would be greatly appreciated.

    Is only Safari slow?

    No, it seems to be the computer in general. It is only udsing 20-25% of the hard drive and I ran virus scans, but It keeps getting bogged down.

    Where did you get BitDefender from? If you got it in the App Store, that version is quite benign and cannot cause you problems. However, if you installed the full version, it's possible that whatever background scanning is going on might be causing more problems than it is solving.


    What malware did BitDefender find? What was the exact name? Most likely, it was Windows malware attached to a junk e-mail or something like that, but the name can help determine for certain whether it's anything to worry about. (It's very unlikely that you need to worry.)


    As for the performance problems, see my Mac Performance Guide.

    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.
