I installed the Samsung Evo 860 SSD in 2011 "15 Macbook Pro El Capitan this morning and it works wonders! The laptop is on speed steroids. So, I checked the system report and it says no TRIM Support. The TRIM Support was enabled on the original hard drive that it came with the laptop. Should I enable it or should I wait and try to update the OS to Sierra and see if it works? Or does it even need to be enabled at all for SSD?
