    Hello everyone. I have a MacBook Pro 15 Inch, Mid 2010. Specs are 2.66 i7, 4GB Ram, Nvidia GT 330M, and a 500GB HDD

    Basically the title says it all, everything I do is terribly slow, opening applications is the most frustrating as it can take up 5 or more minutes just to open more than one app at once. And its nothing crazy like oh open these 10 apps please at light speed, no I mean like open safari and system preferences. If I do that everything goes to ****. Some things I have done to try and solve this would include running Onyx for housekeeping. That didn't work so I reformatted the whole thing, completely erasing the drive, and the problem still persists. I have checked the smart status of my hard drive and apparently its okay still, but I feel like my hard drive is dying slowly and painfully but I have no clue because this has been going on for a while, so any help is greatly appreciated as I would like to not go drop 2 grand for a new macbook.

    My suggestion is to buy a SSD and then reinstall OS X. The machine will feel like new after that

    Would also be worthwhile putting your original HDD in a USB caddy and booting from that to see if things improve as it could be a failing SATA cable that is causing the issue

    Agreed, another vote for getting a SSD, my Mac Mini felt like a brand new computer when I put a SSD into the old girl.

    It could be the drive but it could be the cable too. I used Scannerz to test my system when I was having SSD problems and it's diagnostic mode has an option specifically to test the cable. You can review the product specs at if interested.

    FYI the first SSD I had went bad. Probably one of the memory chips was defective, so don't think they're invincible. AFAIC SSDs stand every bit as good a chance as going bad over time as a hard drive. However, your system is 5 years old, or at least approaching that, so the drive is a good possibility. If, however, the cable is bad, and these units are known for having cables that fail, if you put a new SSD in the problem will still be present.
