Chameleon SSD Optimizer is an optimization tool for Solid State Drives. It can enable TRIM on non Apple-branded disk, increase durability reducing I|O writing cycles, set hibernate mode and save space disabling sleep image. Chameleon is able to read sata system profiler info and you can easily check trim status, disk speed or properties. We added the reading of S.M.A.R.T. data how OS X does, so you can control the temperature, the firmware version and more. Now you can disable the local Time Machine, the Sudden Motion Sensor or noatime set for the system.

A query to those who know more about TRIM and SSDs than I do:
I have a MacBook Air 2012 that came with SSD so I understand (correctly?) that there is no need for 3rd party TRIM as it is enabled with Apple devices? I ask as the System Information does not list TRIM as an option under the Storage tab.

I do have an external SanDisk 128GB SSD that I use for Time Machine. I believe (from what I have read here and elsewhere) that I should install TRIM for this external SSD. As with the internal SSD, System Information does not list TRIM as an option under the Storage tab for the external SSD.

Am I correct in my understanding? If someone who is more conversantwith TRIM could answer, I would be thankful, and I suspect others would be also.

Is there anyway to check Apple support (or otherwise) for TRIM on SSD on MacBook Air?

It will be enabled as it's an Apple supplied drive. So no need for software like this to enable it.
System Information shows TRIM support under SATA/SATA Express and then the drive name. It's not shown under Storage even though it does seem more obvious.

I tried it with the Yosemite Beta and my MacBook would no longer boot. All I got was a progress bar at startup, underneath the Apple logo, which never completed. Instead, after several minutes, the computer displayed an international "Do Not" symbol and hung. It's not my main computer so the failure wasn't critical. Still, I had to reformat the drive and reinstall the OS, which took forever.

do you think we should pay to enable trim?

I contacted the developer through his web site. He gave me a temporary fix. He said he is working on the Yosemite version of Chameleon.

Chameleon Dev.

If you anytime(any PB and any minor/majar update) support TRIM enable, I pay share fee.
I want to pay for nice hack dev.

Thank you for updating this free software. Trim Enabler works fine, but charging 10 bucks for a thing you can do with one simple command from your terminal is just stupid.

Trim Enabler is free to use for most feautures. It is only when you want to use things like the speed benchmark that you need to pay.

As of July 2, 2014, this program doesn't seem to be compatible with 10.9.4. It was working fine on 10.9.3, I went to .4. TRIM support went from Yes to NO in the OS X sysinfo, as expected after a system update. I REAPPLIED Chameleon, and Sys Info still showed NO for Trim support. My first clue that this probably wasn't going to work was that after the update to 10.9.4 and first launching Chameleon, under TRIM support in the program (not OS X sysinfo but the Chameleon program itself) it didn't say No, but 'Unknown'.

I tested this on throwaway test partition, so no harm done, but suggest you should not update to 10.9.4 until this is worked out, or find another TRIM solution.

Afterwards I did a check of the IOAHCIBlockStorage.kext file (unaltered) between 10.9.3 and 10.9.4 and they are binary different so I suspect the position of the "Apple OEM" string in the file that Chameleon tries to modify has moved, which means that the Terminal commands floating around the web to do the same thing probably would fail as well?

at this site http://www.return1.at/trim-enabler-for-osx/

they appear to have updated the Terminal commands with the proper string positions for 10.9.4, confirming that in fact it DID change from 10.9.3.

sorry, check website. I uploaded a beta for 10.9.4 but i didn't update here.

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

ChameleonSSD 0.9.4 was working great up to 10.9.2, but since this update I can't enable TRIM anymore. If I switch to ON it loads, restarts my MacOSX and after that it's back to OFF/Apple Only.
Is this a common issue or is it happening only to me?

Works fine on my Mac Pro after the 10.9.2 update. Just had to re-enable it (as if I were running the app for the first time) and let the machine reboot. Some updates overwrite the files the app changes, so it's necessary to reapply the changes via the app after such an update.

Having said that, the procedure at the link you provided should work if the app doesn't for some reason. I'd suggest contacting the dev if you try again and can't get this app to work. I emailed him last night about something else and had a reply this morning; my reply to that message got a nearly instant response, so he's definitely out there and listening.

Thanks Brossow, I know I have to reapply the patch every time the OS gets updated, but this time it wasn't working anymore. Probably it's something related to the permissions, but using the script I provided fixed the issue (before that I tried repair permission, reboot, and again Chameleon with no go).
I was already talking with the developer about this issue (he's very kind!) but it seems it was a specific problem with my installation, not related to Chameleon which is working fine on 10.9.2. :)

I usd this enabler because it was recommended by Intel support as I bought a new 530 240g SSD for my Mini. Only ever used Intel because its so part of Mac and it just "works". Rather than go through the terminal command which I did up until now and also reading about the fued between Trim enabler (O.Groth) and the other chap G.Panell I thought if it's good enough for Intel, then it's good enough for me.
Installed it on my new drive which was cloned by CCC and upgraded to Mavericks OS. Hit the button and rebooted when it aske me. There is a minute or two whilst it goes through the automated Terminal commands but thats just tea making time. Then do a system profile and ther it is ...Trim enabled. Job done.
From what I have read, is that whenever there is a OS update/upgrade the trim will revert to "NO". So you just run Chameleon again.

After I installed my SSD and Chameleon SSD Optimizer, SmartSleep started behaving oddly. Are they compatible? Some of their controls overlap, specifically regarding sleep image, hibernate mode, etc.

Chameleon is compatible with smartsleep and similar software, I don't know if smartsleep can works with another software that check and change the sleep status.
