Q: MacBook Pro (Late 2011) Lagging

I have a couple year old MacBook Pro 13" Late 2011 model with upgraded insides

2.4Ghz Dual-Core Intel i5, 8GB RAM, and a 128GB SSD.

 

Lately (past month or 2) it has been running pretty slowly. I've used CleanMyMac2, Onyx, etc, which helped for like a day, but then it went back to lagging. I even reinstalled OS X twice overall which speeds it up immediately but the second I start loading my stuff onto it (Only certain apps, music and photos - no save data/prefrences) it goes slow again. I've also reset PRAM and SMC just in case.

 

I ran an extended Apple Hardware Test and it says my Mac is running perfectly, so I'm a bit confused as to why it's acting like this.

I'm at my whits end, I miss my Mac that could run laps around PCs. Early next year I am considering getting rid of my Macbook (or keeping it - depends if I can sell it or not) and getting an iMac, I need more power than this =/.

MacBook Pro, OS X Mountain Lion (10.8.4)

    Not enough free space on the disk can slow your Mac down.

     

    Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage

     

    Make sure there's at least 15% free disk space.

     

    BTW, third party cleaning utilities (especially two) are overkill and unncessary on a Mac. Your Mac run maintenance in the background for you >  Mac OS X: About background maintenance tasks

    Out of 128GB I have 95GB free lol! I store everything on an external drive. and I only clean the cache and app uninstall leftovers with CleanMyMac2, and Onyx was a last resort.

    Using CleanMyMac won't do your Mac any good. It's a useless utility and could be causing the drive to slow down.

    Back up all data immediately as your boot drive may be failing.

        

    If you have more than one user account, these instructions must be carried out as an administrator.

      

    Triple-click anywhere in the line below on this page to select it:

    syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|Previous Sh' | tail | open -ef

    Copy the selected text to the Clipboard (command-C).

     

    Launch the Terminal 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 Terminal in the icon grid.

     

    Paste into the Terminal window (command-V).

     

    The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.

     

    A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that.

    The only thing in that file is: Sep  5 00:28:41 Austens-MacBook-Pro kernel[0] <Debug>: disk0s2: I/O error.

     

    disk0 is my SSD....

    The boot drive is failing, or you have some other hardware fault.

    Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

    Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.

    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

    *An SSD doesn't need to be zeroed.

    Hello Davis,

    I, too am having a lag issues (specifically when I run the visualizer in iTunes or scrolling in Chrome).  I ran the above terminal script and:

    Dec  5 07:09:01 localhost kernel[0] <Debug>: Previous Shutdown Cause: 5

     

    I'm running Lion on a late 2011 Pro with 16GB of mem.

     

    I don't suppose you might have a thought or two regarding my issue?
