Trim is must-have feature for most Solid State Drives. It not only increases data writing speeds, but it increases the lifetime of the SSD itself. With Trim Enabler, you can bring that feature to Mac OSX. It's as easy as flipping a switch.

What's New

Version 3.2.4:
  • Fixed an issue with the helper application
  • Added a accessibility menu item. Blind users can now use the Actions menu item to enable/disable Trim
  • Fixed some French translation issues Trim Enabler

Requirements

  • OS X 10.7.0 or later

Version 3, which is a menu bar applet, misses an obvious interface element to quit the applet when I don't need it any more (cmd-q works when the menu is open).
Haven't registered to try the pro features, but basic options seems to more...

If you have SoftRAID, it can enable TRIM on 3rd party SSDs.

Nice pickup. Thanks. Does this apply to non-SoftRAID volumes, though?

Support for hardware RAID depends completely on the RAID card/controller. Generally, they don't support Trim.

Version 3.2.1 was unusable on my Mac Pro 2010 with 10.9.2 (immediate crash). The current version does not have this issue anymore and now everything works as expected. Thanks!

Hi, this is a bug with the 3.2.1 version and OSX 10.7.
Please downgrade to 3.1.3 while I sort this out.
3.1.3 can be downloaded here:

V. 3.2.1 crashes on my Mac Pro 2010 (10.9.1) - EXC_BREAKPOINT (SIGTRAP). Surprisingly, the previous version works fine...

Hi, please create a topic on the support forums (groths.org/forums) where you detail the error and what system you are using.

Diarbyrag,

Short answer...the preponderance of evidence is that TRIM would improve performance of the SSD, that is, provided, as in your case, you have a thunderbolt connector.

Are Trim enablers necessary for the newer SSD's drives? Presently, I have a LaCie 120GB SSD and the LaCie tech support indicated it is not needed.....is that correct?

FYI....the issue with a SSD with a USB connector is that the SSD will not be recongized by the Mac and hence no support....see full reponse:



If we are talking about P9223 SSD on Mac..

SSD itself supports TRIM.
But through USB 3.0 device is not seen as SSD so no TRIM support in USB 3.

Through TBT, SSD is recognized by OS, so TRIM may work but Mac OS does NOT support TRIM on EXTERNAL SSD BY DEFAULT.

With TRIM enabler Mac OS should manage TRIM on the external SSD. (but remember you "force" the OS to do something "special" that it is not supposed to do ...)



Thank you, and please let me know if you have any further concerns.

ie. short answer needed > is it required/does it help or is it a waste of time on new macs, I have new MacBook pro late 2013 & LaCie 120GB ssd rugged drive

As of 9/19/13 links for Trim Enabler 3.1 resulted in a zero byte file download. The download through MacUpdate Desktop was a correct dmg file. I guess if that makes me a shill for MacUpdate, so be it...

It should be noted that Trimenabler is no longer totally free. For so called advanced features, like SMART status information , you have to pay $10.

True, but these are new features. So what was free still is, for some new 'pro' stuff you have to pay.
I actually don't need the 'pro' stuf, yet still payed because it is such a great app to bring out the potential of your SSD!

"So what was free still is".
Not Quite SMART was also available for free.
There is nothing bad to support the developer though.

@Ratti
You are right of course. It is just that I have many more apps that look at SMART for me so I did not put value on it, but that is personal indeed.
I stand corrected!
