About a month ago my white Macbook Unibody (late 2009) started running slow. Programs that would once open in ~5 bounces (on the dock) are now taking over 20. When I type, the words wont appear on the screen until a couple seconds later when it will shoot out 8-10 words all at once. Applications like powerpoint are hardly usable because it's so slow, I start to get the beach ball whenever i click anything. Itunes movies skip.. The picture will stop moving and the dialog will continue (this happens every few seconds and last 3-4 seconds, so movies are unwatchable).

 

Here are My Stats:

OS X 10.8.2

2.26 GHx Intel Core 2 Duo

4 GB 1067MHz DDR3

337 GB Free out of 500 GB HDD

 

I have repaired Permissions, Verified Disk, restarted in safe mode, reinstalled the operating system, cleared junk files.. Theres nothing on my desktop. Nothing eating up CPU or Memory in activity monitor. S.M.A.R.T. status is Verified.

 

I appreciate any help very much!

    You appear to have conducted a lot of research already, but have you tried the following?

     

     

    Despite what Apple Hardware Test may conclude, if the problems still exist in Safe Mode or when using a different User Account, you may still have a hardware problem that AHT did not detect. Schedule a Genius Bar visit to have your Mac evaluated:

    The following may help, but if the same behaviour exists after exhausting the above suggestions it is unlikely to reveal the problem. Try it if you wish - it's easy enough.

     


    Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Go to his website, download and run EtreCheck:

     

    http://www.etresoft.com/etrecheck

     

    The rainbow "wait cursor" will appear for a brief moment as it collects its data. Do not be concerned about anything that says "Problem" or "failed".

     

    Copy and paste its output in a reply.

     

    EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.

     

    When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.

    If the problem exists in Safe Mode, as well as when using a new User Account, the system modifications that I would usually suspect should be inactive. Most notably WD SmartWare, which is not required to use their drives, and has been found to cause problems.

     

    CleanMyMac has been known to remove essential system files that cannot be restored without completely reinstalling OS X.

     

    I suggest you use OS X Recovery and use Disk Utility to repair the disk. Make note of any errors it finds. After that, reinstall OS X due to the uncertainty associated with CleanMyMac. Reinstalling OS X will not erase any of your user accounts or data. Remove CleanMyMac according to the developer's instructions. Run Etrecheck again to ensure it is completely gone.
