TRIM SSD Support Enabled in Mac OS X 10.6.8 Update
The recently released Mac OS X 10.6.8 Software Update has quietly added native TRIM support to Macs equipped with SSD drives. TRIM insures that your SSD drive will be functioning at optimal speed and extends the life of the solid state disk, making this a must-have update for any Mac user using solid state storage.
Enabling native TRIM support on your Mac’s SSD drive is just a matter of installing the Mac OS X 10.6.8 software update and then rebooting your machine. Installing the OS X 10.6.8 update eliminates the need for the assorted third party hacks that surfaced to hack TRIM to work, so it may be a wise idea to disable those tools before installing the official update.
Mac OS X 10.7 Lion also includes TRIM support natively, and is due for a public release sometime this July.
Update: We can confirm that TRIM is enabled on Apple provided SSD’s with 10.6.8 installed, but some third party SSD’s continue to not support TRIM despite the update. Lion may address this, or you can continue to use the third party TRIM Enabler tool.
There is the Angelbird SSD with native mac TRIM support.
No hacking needed. Works out of the box!
This worked with mac mini mid 2011 with Plextor 128M2P and OCZ vertex 2
Hello!
I have an iMac (27″ 3,4 Core i7 1TB…) and i put an SSD into it(Kingston SSDNOW V100). I have lion on this, but the TRIM is not working and the machine crash always after one week…
I tried to fix with these apps, but these are not working.

MBP 5,3 with Apple TS256A, TRIM support still says “NO” after 10.6.8 update. Any ideas?
I have the same drive (APPLE SSD TS256A) and even upgraded to Lion and the Trim support still says “NO”.
I’m not sure why this drive seems to be the only one with this issue. Every post I read pertaining to this drive and Trim Support is having the same issue.
Hopefully someone could shed some light on the problems soon.

Trim support has been around since 10.6. OSX daily even covered it. why is this news?
https://osxdaily.com/2011/03/04/mac-os-x-10-6-to-get-ssd-trim-support/
meant to say 10.6.6
That was specific to MacBook Pro 2011 models, the 10.6.8 update expands to all Apple provided SSD’s
ok cool
same model, apple TS128A, trim=no
APPLE SSD TS128A , TRIM = NO – any idea why? have you found any solutions to that? just wondering :) peace.
Same here. APPLE SSD TS128A, TRIM=NO :(
Trim is still not enabled on my late 2008 aluminum macbook with an Apple SM128 128GB SSD on 10.6.8.
Important to note that in order for the TRIM support to actually DO anything on a drive that has been in use, you MUST perform the procedure listed above, in order to re-write the files that were previously written without the TRIM support.
I got my OCZ working with Trim Enabler 2

YMMV
here’s directions from MR forums:
*************
To TRIM your disk after enabling TRIM:
1. Open Disk Utility
2. Select your SSD from the right-hand-side bar
3. Click “Erase” tab
4. Select “Erase Free Space…”
5. Select the fastest method (no need to add extra write cycles by doing it multiple times) and click “Erase Free Space”
If you run Erase Free Space, you should run these commands in the terminal afterwards:
sudo chown root:admin /
sudo kextcache -system-prelinked-kernel
sudo kextcache -system-caches

The same in Intel G2 80GB SSD (no TRIM)
TRIM is also no for second generation Intel X25-M.
No TRIM for a 120GB Intel X25M neither.
Well that answers that! I would agree that Apple has good reason to enable trim on their branded drives.
OWC Merc SSD’s are quite the performers, unfortunately the cost of SDD’s can’t be justified as I am running the Seagate XT Hybrid… performs awesome. Also my newborn does need diapers. ;) Maybe by the time she doesn’t need diapers, SSD’s will be CHEAP!
Many new SSD’s have advanced garbage collection methods and don’t actually need TRIM at all. Be cautious with that aftermarket TRIM Enabler app with new SSD drives, it can actually slow them down. I would say use TRIM when Apple supports it only, there is good reason they are not enabling in all drives by default until OS X 10.7.
Read the comments on http://www.groths.org/?p=308 to see some firsthand reports.
I have a really old OCZ that I paid a small fortune for and it’s still not working. Too old of firmware maybe? Bah, wait for Lion and cross our fingers I guess.
Trim=No on my OCZ Vertex 2 240 GB – any suggestions?
That’s why you’re a stupid pirate running a Hackintosh. You’re lame.
Works for me, Apple branded Samsung
My 250 Gb Apple SSD is fine and now Trim enabled but I have a 48 Gb Express Card SSD in my 2010 Macbook Pro. System profiler reports Trim Support on this as No.
Is there any way to enable trim on this please?
Doesn’t work with my OCZ Vertex2 SSD.
I’m running C300-CTFDDAC064MAG. 10.6.8 says TRIM = no to me.
Is the native trim only for Apple SSD’s, or will third party SSD’s be supported?
I have a feeling it’s only for Apple SSD’s
Good question, I can confirm only for a MacBook Air with Apple supplied SSD but I have heard it extends to some others. I’ll update when I hear more.
I think you are not right, because I have a MBP 2009 issue
with Apple installed 128 GB SSD by Samsung, and SL 6.8.6 s/w. My current System Profile says No to Trim Support. How can I get Trim active for my 128 GB ssd? Will Lion do it?
FINALLY!
