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.

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!

Works as advertised, but I'm not liking the iOS 7 GUI. I wish developers stick more with the correct GUI for the correct operating system.

Abbott

I agree. Would much prefer an OS X interface over iOS.

Part of the iOSification I really dislike is all the in-app purchase links, which I found very annoying. It's fine for the author to seek payment, but I'd much prefer a single subtle button like "find out about advanced options" button—just ONE button. Or else allow us to just click ONE place, say "not yet" and then have ALL of the add-in options simply be grayed out or vanish altogether.

I'm sticking with v2.x, which had a very nice, clean, usable interface.

I rather like the new interface via the Menubar (: Also have the pro version and the program works very well!
On first launch the program warns me that, in my occasion on a 10.9 Preview, trim is already 'Activated' via Mac OS.

I've also performed some tests with both the build in benchmark test and the Blackmagic disk speed test program.

I can say for sure that, on my MacBook Air 13-inch Mid 2011 with a 1,8 GHz Intel Core i7, the performance is MUCH higher with Trim Enabler 3.0 activated!!!

Sequential Reads reaches a steady 395 Mb/sec with Trim Enabler 3.0 activated. Sequential Write and Rewrite are a steady 255 Mb/sec with Trim Enabler 3.0 activated.

Maybe it's because the Mac OS Trim in 10.9 is still in beta/preview, but the results are much lower and very unstable.

Sincerely.

@Dokter_mac correct me if I'm wrong but isn't trim already enabled on the MacBook Airs with factory SSDs/flash storage?

Also, doesn't trim only speed up writes not reads?

Dokter_mac
+0

@macambulance: You're asking very good questions!

-Yes, the majority of Macs with an ssd HD installed from within the factory are Trim enabled by default. Only the very early ssd HD's where not enabled. Now if you upgrade your Mac with a ssd HD for a speed bump and you buy one in a store, then you have a big chance that trim is disabled. It's a PC thing... Windows you know ;).

-On your second interesting question I have to answer also yes you're right! My test results with the benchmark app proves this also.
It has to do something with how the flash memory in ssd HD's works... When you enable Trimming you're force the ordering of the MLC in a ssd to write/read/rewrite in a Page that it only can save in 4k! Even when you're file is 1k. The result of this ordering of the MLC is faster write/rewrite, for obvious reasons (all the MLC's in a Page are 4k). The reading of a trimmed ssd is in some cases also faster because of that. An example is when the ssd HD is almost full. It keeps the read speed constant.

I hope that my explanation is somehow understandable for English speaking people :) My language is Dutch and I'm from Belgium you know... And please correct me if I have made a mistake because of that...

Sincerely.

That's what I thought, which is why it was odd that your 2011 MBA would get such a noticeable read rate increase given that it would already have trim enabled without the need for 3rd party software.

My 15" MBP has a Crucial M5 in it, and is definitely faster at saving large files with trim enabled, but I wouldn't expect it to start up any faster (only take 8 seconds as it is) ;)
