TRIM Support Enabler

Cindori: 2.66 i7 MacBook Pro w/ 200GB Vertex 2 here & 8GB of ram here.

Any idea why enabling TRIM would make the system seem to run better overall, but slowdown browsing in Chrome/Safari/Webkit to a crawl?

Unfortunately, I had to disable TRIM due to that side effect.

Deleting files also took significantly longer.

Apple's implementation of TRIM definitely seems like it isn't ready for primetime.

So I got overly excited and hit Patch before hitting backup. Am I f'ed? What happens if I hit Restore? Will it do nothing since I didn't hit Backup first?

Anybody have manual instructions on how to roll back if I need to? Worst case I can just reinstall Snow Leopard right?

Edit: Just to add I have a 2011 MBP with an OWC Mercury Extreme Pro 250GB SSD and this worked fine. It says TRIM support enabled and my boot time was very fast, faster than before. Also everything else (day to day use) seems snappier. Browsing is just as fast if not faster and deleting files, etc. is fine too.

I wonder why other people are having other issues.

Just tried this and my boot / shutdown times plus performance have increased dramatically. Not had much time to test it fully yet as got to look after the little one, but before shutting down and checking about this mac, I've lost 2GB of RAM. Red light on the riser is on. Complete coincidence? The RAM was pretty hot and it wouldn't be the first time I've had it go (OWC lifetime warranty). Are there any risks associated with running something like this? It's put my system back to how I would expect it to run but if it's gonna hurt stuff then I'll go back. Cheers.
 
Great tool by the way. Thanks! How come this makes my system so much faster? I mean, the spinning cog at the beginning has gone from 25 rotations down to 6 and I'm in! Also, running Logic Pro at a fairly low buffer size (128 Samples), with a fairly large project used to be a bit clicky when skipping to different sections (Project disk is Intel 2G SSD) but now it's smooth. I'm very impressed as long as it's not taxing my hardware! Cheers.

So even if I didn't hit backup, restore will still restore the default kext if i choose to?

It will restore to a MBP 10.6.7 default driver, that has support for Apple SSD trim only, and is not hacked.
Has worked for everyone.

If you definately absolutely positively must have the exact old driver you were using... just download the combo update pkg from apple, open it with pacifist, pull out IOAHCIFamily.kext, and restore with the tool...

You doesn't. The software which has been put together by Cindori makes the OS X to operate properly with SSDs that do it automatically. TRIM is to be enabled, not executed by the user. The SSD does it by itself.

That's what I wanted to know. Thanks.
 
This thing worked wonders on my 120gb owc extreme pro. Halved my startup from 24 to 12 secs. Top work OP!
 
Hello, which file is the latest? enabler.zip or TRIMenabler.zip?

On the website, both are posted... (?)

Thanks,

Just installed my brand new 120GB Intel 320 Series SSD and cloned my boot drive over to it. After confirming everything was working well, I ran the Cindori's tool to activate TRIM for the drive. Did not bother erasing free space or running the Terminal commands again, as the drive is fresh out of the box and I haven't used it, so any free space on it should never have been written to.

Ran XBench again, the results are attached along with a screenshot from System Profiler. You can compare against the results immediately before activating TRIM and rebooting once in the post linked to from the above paragraph.

There was a decrease in some speeds after activating TRIM, but I doubt the difference is significant or even related. Of course, since the drive is brand new, I did not expect to see any difference at all in speeds. I would attribute the differences to normal variance. I did not notice any difference in boot times or the time it took to empty the trash (will continue to test these more in the near future).

Will report back if anything changes! In the meantime, thanks Cindori!

I also had to restore due to poor Chrome performance. Using Google Maps was very frustrating after enabling trim, and flash games lagged badly. Restoring fixed the issue. Another thing I'm noticing, now that I'm restored to default, is that bootup time is actually faster with trim disabled.

Things seem to be going good, fast, stable, all OK.

But, I seem to be leaking disk space. After erasing, re-patching and all, I had 40.1 GB of disk space, now I have 40.06, this is over two days. Went from 40.08 to .06 in just 4 hours of use, web browsing, some emails.

Maybe I am more sensitive about it since I am in "Q/C" mode? Hardware is 09 MBP 13" 2.53, 8GB of ram, Intel 160GB G2 SSD.

Or.....?

What type of SSD do you have? I ran this on an Intel X25 G2 and a 2010 MBA and am not seeing any negative trade-offs with the same applications you mention (except I don't play flash games so can't compare).

I ran the patch, erased disk free space and ran the patch again.
 
Can't seem to get the terminal commands to work. Running the 1.1 ver 2 caused the same issues...

Code: 
mac:~ user$ sudo chown root:admin /
mac:~ user$ sudo kextcache -system-prelinked-kernel
Can't create kext cache under /System - owner not root.
mac:~ user$

Any advice?

sudo touch /System/temp seems to work ok?

Edit: fixed
sudo chown root /System
 
Thanks really easy.

Just backup, patch, reboot and it works.:cool:
