    I'm looking at buying a 3rd Party SSD to get some speed improvements for my aging Macbook Pro. I've heard conflicting information as to whether TRIM is possible for a 3rd Party SSD or it's still something that Apple don't allow.

    Thanks in advance!

    On OS X TRIM is not enabled by default with third party drives, but with the newer OS versions Yosemite and El Capitan it is very easy to enable. Just install the drive and the OS then run the command below in Terminal and reboot and you will have TRIM.

    Code:
    sudo trimforce enable

    Yep, force enabling trim on 3rd party even thunderbolt externals is quite simple as shown above with the terminal command, did it on my samsung 850 evo that i have in a thunderbolt enclosure.. OS X sees the drive as a SMART/TRIM enabled SATA PCI-E connected drive, i love it.
