Trim Enabler

Steer clear of this company, especially for something as key as a disk utility. Their Zendesk customer support site was disabled and they never responded to my report that their app was flagging that it was out of date when it wasn't.

I've have had this App and used this before on an ssd and nowon this one and am able to track the health of this one also.

Use Terminal command for free TRIM: sudo trimforce enable Type password, type y (twice) and wait for restart.

Works really well in Mojave (to 10.14.5 thus far).. Have it on multiple upgraded 5690 MacPro 5.1's with Samsung SSDs as Boots and Storage.

This is a MUST have if you want to have SMART on all of your drives! Recognized by DriveGenius and others.

Beware! Trim Enabler 3 is not working with High Sierra and Cindori asked me to pay extra to upgrade to 4 so that I could use it on 10.13. Thus beware before investing in apps that are not future proof (as a matter of fact Condori are one of the few - if none - developer I know who asks for money after purchasing their product so that it works on macos upgrades!!). Buying this product will most probably draw as well some more money from your pocket sometime in the future. Not to mention that you can enable trim in the terminal with one line of code...

google how to enable trim on macs, apple's own site shows what to do ;-)

Not sure anyone would still need this. macOS enables this for all SSD support trimming.

There is an issue with version 3.6 that causes the Trim Enabler pane not to appear when the program is started on at least some systems (reported so far for systems running 10.7.5 and 10.8.5). The developer is working on resolving the problem.

Not sure but doesn't OSX10.11 enable trimming for support for all SSD even if it is not an official SSd from Apple?

Exceptional program! Worth every penny! Thanks to the developer! =D

Trim Enabler is no longer working (at least for me) under 10.9.5 since I instaled the latest security update (2015-008 released today december 9 - 2015). Looks like the patch isnt sticking anymore, despite turning it ON and reboted numerous times. Hope there will be a fix soon. Otherwise it's a great software that I purchased long time ago !

Good stuff, have used it for years (payed version) but thanks to Apple - no longer needed

IF YOU OWN A SAMSUNG EVO OR EVO PRO, 840 OR 850, be sure to install the latest firmware before turning on TRIM support
http://www.samsung.com/global/business/semiconductor/minisite/SSD/global/html/support/downloads.html

There is a lot of confusion about the multiple issues with the Samsung and the need for firmware update. Some users are insisting the problem is only with Linux, and you don't need a firmware update. Not true, there are actually TWO critical issues discovered so far with the EVO drives, one Linux related, the other NOT.

One problem, related to the drives having an incorrect bit set that tells the OS what type of NCQ queing command it supports. The incorrect bit says that EVO supports beyond normal sequential queued TRIM commands (it does not) and then Linux attempts to implement (which does support more than sequential) and runs in to problems.

Windows and OS X ignore this bit because as of now, they only support 'normal' sequential TRIM, so is unaffected BY THIS ONE PARTICULAR PROBLEM.

HOWEVER, there is ANOTHER issue with Samsung EVO related to reading data that is 'old' (not been accessed for a long time) where the charge may degrade, requiring multiple attempts to read the data. This problem is not OS specific and deals with the actual physical nature of the drive itself. The latest firmware from April 15, 2015 fixes this by periodically 'refreshing' in the background all the data on the drive to keep the charge strong, even data that isn't accessed. This problem affects the drive regardless of OS, so highly recommended you update the firmware. Read more about this SEPARATE PROBLEM UNRELATED TO THE LINUX PROBLEM HERE:
http://www.extremetech.com/gaming/203449-new-samsung-840-evo-firmware-will-add-periodic-refresh-capability

Firmware update is provided as an ISO bootable CD image that will boot Macs or Windows PC., using a Linux micro kernel, that locates and updates the drive. I've updated without issues.

As for all the conspiracy theories about why Apple did not enable trim support for non Apple branded SSDs, until now, this is a perfect example. Apple no doubt tested all kinds of brands and manufacturers when deciding who to use in their own machines, and likely found that many had bugs in their implementation TRIM. This has been confirmed now in early drives using Sandforce controllers in which live data could be incorrectly marked and deleted by using TRIM. Apple did not want people turning on TRIM with other drives, and then be accused of data loss or issues which were outside of their control, and be BLAMED for it, as people would automatically assume based on their experience with rotational drives that 'it can't be the drive, it must be Apple'. BAM ! Class action suit. So after testing and finding out the brands they would NOT use in their machines, Apple decided the safe approach was only enable TRIM on the drives that passed their testing. Publicly, Apple would never issue a list of BAD drives; that's not their responsibility, and they have complex relationships with component manufacturers they have to protect. Company X may have a bad SSD that Apple won't use, but it still buys memory chips from X, for example.

To that point (that some SSDs brands are not fault free or were not early on) here it is mid 2015 and even a brand as popular as Samsung EVO, we're still discovering issues. If you have an older drive with a Sandforce controller, you may want to consider upgrading too. Note that OWC which sells SSDs using Sandforce controllers, from day one tried to convince everyone their drives didn't need TRIM (bogus)....well now we kind of know why they were saying that. Amazing how their marketing turned what was a undisclosed bug into a reason to buy the product.

To enable TRIM on 10.10.4 and above, simply type sudo trimforce at the UNIX command prompt! You don't need a TRIM application any longer...

Good news at last,

https://www.cindori.org/trim-in-os-x-el-capitan/

"In Mac OS X 10.11 El Capitan, Apple has done a full 180 and opened up parts of their driver that allows access to Trim functionality.
This is great news for Mac users around the world that are using 3rd party SSD’s. In Yosemite, we had to deal with lifting a lot of security features in order to benefit from Trim.
With this new driver functionality, we can enable Trim in El Cap (and upcoming Yosemite 10.10.4) without risking the issues with gray boot screen."

I just bought a Samsung SSD 1 TB, 850 EVO for my late 2013 27" iMac, model 14.2. Then I heard it may not be compatible with Yosemite. I called Samsung, they said I need to download Trim Enabler, and it should be fine. He didn't inspire confidence though. Is he right? My SATA is 3.5". Do I need a case or enclosure for my 2.5" SSD? Can both drives coexist? thanks

Please note that some SSD drives do not support TRIM. It is easy to find out if your SSD drive supports TRIM .Do the following: -Launch "About This Mac" under the Apple menu -Click on "System Report" - After it loads, Click on "SATA/SATA Express" - Click on each of the drives till "Medium Type" in the list says "Solid State". - The line right below this will say "Yes" or "No" to "TRIM SUPPORT" If it says "NO" TRIM will NOT work on your SSD.

Might anyone be able to point to link that tells how to totally remove Trim Enabler and restore back to default? In this case, it was version 3.0, which was installed on 10.6.8, where it seems to be unsupported. If this info is on the developers site, I have not been able to find it.

I have a 500 GB Crucial M4 SSD in my MBP. After updating to Yosemite I disabled Trim Enabler. I don't know if this has anything to do with it but I just had the second time since then that the Microsoft Entourage database containing my mail got corrupted. The first time it happened I rebuild it and it went from 9.5 GB down to 6.6 GB. This time it seems I lost all email since 10th of November. Could NOT having Trim enabled be the cause of this?
