It will natively enable TRIM using an official Apple utility rather than a third party work around (hack).
Although, the dev. of TRIM Enabler has said he will be updating the app to use the trimforce command, so once that is done there will be no difference. But for now, I would say using the new command is better.
Yep, Before installing 10.10.4, I disabled Trim in Disk Sensei. After installation I enabled Trim with the Terminal, and viola, Trim is enabled on all 4 of my Samsung SSDs. Disk Sensai has the message "Trim has not been enabled, but is working anyway".
Working here, Disabled Trim Enabler, rebooted and ran command "sudo trimforce enable" from terminal.
Be aware its asks to reboot after enabling Trim.
By the way 10.10.4 has black screen background on my Mini now instead of white at startup!
Working on Samsung 840 EVO 120gb
Trim Enabler now reports
"The patch is not active, but Trim is working. You probably have an Apple SSD, which supports Trim by default."
