TRIM Support Enabler

hey folks

i have this SVP100S2256G (kingston ssdnow+) which was beautifully working with 10.6.8: trim enabled, very fast boot/reboot times.

with lion i am experiencing lower performances, especially when it comes to boot/reboot times; trim is correctly installed and i did several times the terminal commands.

anyone else had this issue?

This is 3rd party software related. The same happened with 4 friends and my iMac + MBP 2011 and after I uninstalled the HP software and left only the drivers installed, it's all good now. (With the iMac I couldn't even leave the HP drivers installed so no print there until HP company update their drivers)

Some of my friends had issue with the Stuffit Deluxe magic menu causing that problem and it was solved with the version 15.0.4 of Stuffit Deluxe.
So you figure now that many softwares could be causing that, start cleaning your status bar, finish some services and you will see it all working as it should.

Edit: Just to make myself even more clear, this has nothing to do with Trim or your SSD, it's all about OSX Lion and the softwares installed.

Cheers

In 10.7.2, we have IOAHCIBlockStorage upgraded to 2.0.1 and the IOAHCIFamily 2.0.7. Any new patches?
 
I have the following message in my kernel.log. I could be wrong but I think it's been logged every time the machine (MBP) reboots.

jnl: error 45 from DKIOCUNMAP (extents=ffffff80147ae000, count=25); disabling trim for unknown-dev

I am running 10.7.2. When I run fsck in single user mode, it does show "Trimming unused blocks". It does this very quickly tho, almost no time. Is this normal? I have 50% free out of 320GB.

When I type exit to get out of single user mode, I believe there is a trim error being logged to the screen but the computer reboots quickly and I have no time to read it. I am thinking it's the same error above. Anyone knows what this is?

Also, system profiler reports Trim enabled: yes. I don't think it's working tho. My xbench scores are very poor for the disk.
 
Just to clarify :

The new beta Trim Enabler here is much improved from the previous Trim Enabler (1.1 and 1.2).

Earlier TRIM Enabler distributed a pre-hacked kext which it installed. This was troublesome, because if you updated to a new OS version and repatched, you installed an old kext.

this version copy’s your OWN kext to desktop, and patches it LIVE. that way it makes sure you always have the correct version of the kext, and it makes sure Trim enabler will work on future OS updates.

hopefully the finished version will edit the kext right in your extensions folder, however I am finding this is troublesome to do in Objective-C because of permissions. so for now it copies it to the desktop first.

But any "potentially dangerous" stuff is as of this beta, fixed. It's just a matter of wrapping things up in a nice package now.
 
I'm shortly hoping to install a 256Mb Crucial M4 SSD in my Macbook Pro running OS X Lion 10.7.2 - I'm unclear whether its a good idea or not to run Trim Enabler with this drive - the M4 has some built-in "garbage collection", though I hear its not that great, but would this conflict with the enabling TRIM in the OS?

I've tried to trawl through some posts about TRIM and the M4, but the information seems inconclusive and/or contradictory! Any guidance would be most welcome, thanks!
 
Thanks OP for your hard work dveloping the app and answering questions! It's much appreciated!

I just installed an Intel series 320 SSD on my 2007 MacbookPro 3,1, running OS 10.6.8. Should i use the Trim Enabler 1.1, or is 2.0 good for older OS than Lion?

TIA
 
2.0 works for all OSX with trim capability (10.6.7 and above)

im sorry the latest version still looks like crap, been busy but will try to wrap it up tomorrow
 
v1.2 worked on my late 2007 MBP 3,1 running an Intel Series 320 SSD, 160GB on OS 10.6.8.
I actually couldn't find v2.0 on the OP's website.

I ran the terminal commands, and did an xbench test. My prior untrimmed number was 190.93, now it's 185.44.
I don't really think it makes a difference, and i'm happy with TRIM longevity vs the minor drop in Xbench number, but should that have happened?
Do i need to wait some period of time before seeing an increase in performance?
 
Just used the latest Trim Enabler beta on my MBP 10.7.2 with Crucial M4 SSD and used KextHelper to install it...all worked...Trim enabled. Thanks Cindori.

My question is what about the Win 7 Bootcamp partition on the same SSD? Assume this does not benefit from enabling Trim in OSX, and that I will have to enable AHCI mode in Windows 7 for the native Windows Trim to work. Not a simple task from this link.

Any comment

I found the same thing on my Crucial M4, using Quickbench, a little bit slower with Trim enabled. Not bothered. As you say small price to pay for the benefit.
 
Is there any mac software for life status of SSD drive (not speed test)...
Something like S.M.A.R.T. status for SSD. :confused:

Simple question, I'm sure I'm missing the obvious. Where is my "Recovery HD" after running the 1st step in OPs directions to go from 1.2 to 2.0? I've unhidden files in Finder and see a "Volumes" folder on my boot drive, but when selected, I only see the 5 physical drives. By doing a clean install of Lion on my SSD, do I no longer have a hidden Recovery HD?

After I run the command in terminal, all I get is the following, which I'm assuming is the standard terminal return for this function.

Usage: diskutil mount [readOnly] [-mountPoint Path] DiskIdentifier|DeviceNode
Mount will mount the volume in the "standard" place (/Volumes), unless an optional mount point is specified.

you must use '' around recovery hd
like this:
diskutil mount 'Recovery HD'

Macmini late 2009 and OCZ Vertex 3. TRIM enabler don't work

Hi,

Recently I put an OCZ Vertex 3 90 GB in my Macmini late 2009 (IC2D 2,53 GHz with 8 GB RAM) with Mac OS X 10.6.8.

I want to activate TRIM in Mac OS X using TRIM Enabler but this is the result:

trim.jpg


Translate:

"TRIM Enabler has unexpectedly quit
Click Restart to reopen the application. Click Report to see more detailed information and send a report to Apple
Ignore Report Reboot app"

I use in first time the version 2.0, but then I used versions 1.1 and 1.2 (download from unofficial :-( sites) with the same result

Any idea or suggestion? Can I activate TRIM support form terminal? How?
Thanks in advance
Alberto

PD: Here is the report:
