    Hello, I replaced the harddrive by a Samsung EVO850 SSD 1T few months ago. It was very fast at the beginning. Recently, my machine became very slow again and often I see the beach ball. From the activity monitor, I found that: Firefox 46.0.1 takes 15-45%. kernel_task and WindowServer are the next apps that take up cpu%. Do you know how to speed up the machine?

    How much RAM do you have? Also which OS are you on? Ensure you're on the latest build of El Capitan.

    A few things you can try in the interim to see if it runs smoother:

    - run volume verification in Disk Utility, just to check all is OK there

    - shut down often; once every couple of days, or whenever you're not using it, with the option 'reopen Windows when logging back in' unticked

    - try using Safari instead of Firefox

    Again, the above steps are just troubleshooting rather than permanent steps (though I personally would recommend them). However if they makes a positive difference, that should help towards diagnosing the problem.

    Best wishes.

    Have you checked for TRIM support? About this mac --> system report --> SATA (or however your SSD is connected)
    Non-apple installed SSD's have it disabled by default I think. If you don't have trim on, which cleans up deleted parts of your SSD in the background, any computer will slow down.

    There is a programme called TRIM enabler that I used to force TRIM on for a 2011 iMac with a Crucial SSD installed. Works very well.

    Thanks for the tips.

    I have 8GB RAM. 1TB SSD. 600GB devoted to Mac OS 10.11.6 Currently 16GB left.

    At the end of volume verification, I got a File system verifying code 0.

    Thanks for the tips. Under system report -->SATA, I have:

    Samsung SSD 850 EVO 1TB
    TRIM Support: yes

    As far as I recall, when I first installed the drive to the MBP, I used command line to enable TRIM. From the report, does it verify that I have done that already?
