So, now we know that TRIM is hardcoded in IOAHCIBlockStorage, со does any one know how to hack this driver, to expand support for non-Apple SSDs ??

I hope Developer or Hacker found a way for hack this kext or Bundle and this work for
ALL SSD-Products !!.

Joy my mac friends! Today, from Russia and Germany, there is a discovery of how to enable TRIM Support for third-party SSD. Simply rename APPLE SSD in IOAHCIBlockStorage.kext binary to the first 9 symbols of the your SSD name with spaces if presented, but no more than 9 positions in HEX.

And remember some things:

1) You need IOAHCIFamiliy.kext from 10J3210.
2) Always rebuild the Kernel Extensions cache.
3) Repair Permissions.

Reboot and Enjoy!



And there is a more detailed info.

armdn - is me.

Hav this read: ???
Just a few more things to conclude:
Before trying to activate TRIM, make sure that your SSD supports it. The first models, even the ones that Apple shipped in 2008 do not support it.
TRIM is a command that was implemented very recently in Mac OS X, so it is still hard to tell whether is really makes a difference.
Theoretically, this command prevents the disk from decreasing in performances while it is filling-up.
Also, we can only see that TRIM is marked as active in System Profiler, but we don't have any proof that would allow us to
say for sure that it is really active.
In the next few weeks, we will keep looking into and we will keep you updated on what we find.

As long as no clear evidence of the actual functions are provided, I use it not to not have disadvantages to gain from it.

It works. For me as minimum. Checked with hdparm method from linux. On linux trim is turned off by default.

Only Lion ?
Or Snow Leopard 10.6.6
Thanks

[ARMAGEDDON]

10.6.7 and 10.7

Thank's i dont have 10.6.7 , now upgrade, if send my IOAHCIFAMILY kext to you, please it modifies for me ????

[ntsmkfob]

It's certainly put Trim Support = Yes for my Samsung PB22J SSD on System Profiler. I already had the VBM1901Q firmware installed, which added Trim support to the drive.

I guess someone will do some benchmarks before and after to see if it actually speeds things up. Fingers crossed.

Thanks to Armageddon for putting us on to this.

Here is the absolut fantastic Result for Universal SSD-Trim in MacOSX with More as 1 SSD.
I hav installed this and work !! with my 2 SSD-Drives.

Here read self:

Trim-Universal

Update:

I did just test (benchmark) with Disk Tools Pro MacOSX 10.6.7.
Result: not slow down and not faster speed.
The trim is supposed to be the only slow or stop after a long time? The performance increase
does not come, I thought so.

i hav write here a link for the universal-patch this musst NOT change with
hexeditor !! is it patched finish !!

Here is the Link for this Manual !! and read this please !!!
Universal IOAHCI-Patch

First, download  IOAHCIBlockStorage. It is the binary file, not the extension itself. to reach the original file, right click on
the extension, choose "Show package contents" and navigate to IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage
Replace the original file by the one you downloaded, launch Disk Utility and repair the disk permissions. Check in the list of
results that the replaced file is mentioned and marked as repaired. If it is not the case, repair directly the extension, by
making a command-I on it, clicking on the lock, entering your password, clicking on "Apply to enclosed items..." and then
saying yes to the warning coming-up

and here is this File:
