Samsung SSD 850 EVO (256GB) perfomance issues on Macbook Pro 13" (mid 2011)

Submitted by Jochus on Sun, 07/02/2016 - 12:09 | Posted in: Mac



I recently bought a Samsung SSD 850 EVO (256GB) for my old Macbook Pro 13" (mid 2011). I copied all data from my HDD to my SSD with the Super Duper! app.

After swapping the disks, I noticed my Macbook was constantly crashing. I also sufferered a lot of the so called 'beachball effect'.

My SSD was running on firmware: EMT01B6Q. After upgrading the firmware to the EMT02B6Q version, all problems were resolved.
Unfortunately, I cannot find any changelog for the EMT02B6Q version - so it is still a mystery why the SSD is working now flawly with the latest firmware version ... Maybe it's related to the old SATA2 controller which is in my Macbook? ...

Hi Jochen, - thanks for this great post. I noticed similar issues at a 2011 Macbook Pro 15. How you was able to update the firmware to version EMT02B6Q, - the corresponding Samsung software only runs under Windows. :-(

Hi Clemens,

I upgraded the firmware by attaching the SSD to a Windows machine. Upgrading the firmware on that machine. Then reattaching it to my Macbook.
