Works for me. Installing 10.9.3 disabled it. I ran Trim enabler, re-enabled it, and rebooted. Still active.

I have an EVO 840 Samsung SSD.

Have you tried enabling trim and then restarting your Mac?

Same here. Certainly worth noting that 10.9.3 disables Trim Enabler, though. Not something I'd have thought to check myself.
 
😕 At the third time I used trim enabler and rebooted for the 3rd time and magically have trim working....hard to believe but true not my fault !!!!! 😀

What is TRIM and how do I turn it on?

It is an OS function that tells a flash storage device like an SSD which cells are cleared and ready to be written to again. You can read about it here.

It is on by default with Apple flash storage devices, but with aftermarket flash storage it is not turned on by default. There is a hack that modifies a system kext file that enables TRIM on aftermarket drives. Many people use this app to enable the hack.

Ok thanks. My SSD came with the computer so I'm guessing I don't need to turn it on.
 
absolutely no problem in my Mac.

After upgrade to 10.9.3, the warning from Trim Enabler pop up, and tell me that TRIM is now deactivated (as expected).

I simply enable it and reboot the computer, and then the TRIM function works again.
 
We wouldn't have to go through this silliness if apple just allowed TRIM to be used for all SSDs not just apple SSDs.

Looks like its working for most people, but I can understand the frustration.
 
Tried Chamemeon and when I rebooted the screen turned blue and stayed that way.

Nevermind, just lost all my settings to EyeTv. Everything else is fine.

Same here with the Trim Enabler app v3.2.2. after update to 10.9.3. After enabling TE again my MP just would not reboot by showing only the gray screen and not the shut down spinning wheel. Had to force hard-reboot. My 'simple' workaround was app-zapping and reinstalling the TE app. Works fine now.
