    I can’t download it. 404…
    Any help, please?

  2. Cindori 7 years ago

    It should work now.

  3. Dan 7 years ago

    thanks, worked like a charm on my macbook air.

  4. Mark 7 years ago

    Thank work on my MacBookPro7,1 with an “INTEL X25M G2 160GB” on OSX 10.6.7. I can confirm this upgraded my IOAHCIFamily.kext file from 2.0.4 to the 2.0.5 version. Thanks

  5. Mark 7 years ago

    Also worked on Mac Book Air3,2 with 10.6.7 Can someone advise if these is anything you need to do to TRIM all the existing free space on the drive. HardMac mentioned using Disk Utility Erase Free Space utility?

    MacBook Pro 8,1 Mac OS X 10.6.7, Intel X25-M 80GB SSD im Optibay installation okay, no problem

  7. syzipus 7 years ago

    Thanks a lot.

    It works perfect on my MacBook 5,1 (Aluminum Unibody Model); Mac OS X 10.6.7; OWC Mercury Extreme Pro SSD 60G.

    MacBook 4.1 Mac OS 10.6.7 Crucial RealSSD C300 128 GB firmware 006: Trim enabled

    iMac 9.1 Mac OS 10.6.7 Intel Postville 80 GB firmware 02M3: Trim enabled

    But how to confirm if it really works?

  9. Mike 7 years ago

    could you insert a “trim disable” button,please?

  10. Lichtlos 7 years ago

    works on Lion (10.7) too

    How can I check if it really works?

  14. Sebastian 7 years ago

    Hi,

    Any possibility to add an “disable” button, since I need to go back as my firmware on the OCZ Vertex is too old and I have noted some issues.

    Regards,
    Sebastian

  15. dobuzz 7 years ago

    rebooting in 32bit mode failed! – I got no mouse & no keyboard !
    so now I would like to know: I this a sideeffect of the patched kernel?
    An if so – how could I get the 32bit kernel patched too ?
    Any comments are appreciated !!!

  16. Cindori 7 years ago

    There will be a update with Restore button

  17. mazi 7 years ago

    @Sebastian
    Which version SSD from OCZ do You have ?

  18. SaM 7 years ago

    Wow… Thanks man!

  19. tangles 7 years ago

    Okay, so hats off to Cindori for yet another valuable tool, but I’m more interested in how to test this to determine if ASP is simply reading an attribute/flag of yes from the kext, or is it truly performing trim related commands with/to SSDs.

    Anyone who’s knowledgeable enough, please provide a means to test this.

  20. aone 7 years ago

    Can you point me to the forum with the alternative way to just delete the identifier, please?

    I’m on the iPhone now so I can’t see your app, but if it contains the hacked version of an Apple kext you can be contacted by apple! Remember Airprint enabler (or whatever the name it is)…

  21. Mark 7 years ago

    The following posting describes the approach to manually make the change.

  22. Joel Penner 7 years ago

    I tried this for my 48 GB Wintec Expresscard SSD. It didn’t work.

  23. Chris 7 years ago

    @ Joel Penner: I also have a Wintec FileMate. So, what happened exactly? Did your system crash?

  24. Steve B. 7 years ago

    Will this work on hybrid drives?

  25. Ken 7 years ago

    Although I was able to successfully enable TRIM support for my OCZ Vertex Agility 2 256GB SSD, the performance has degraded a lot. I used XBench to test the performance before the patch and after the patch and the performance has decreased considerably compared to the original state after the patch. FYI, I was using OCZ Vertex Agility 2 Firmware v1.11.

    Could you please release a version to disable the patch?

    Any help would be greatly appreciated.

    Thanks.

    Installation workes (MBP2010, Crucial C300) but
    there is a large decrease of performance at application-starts
    and reading large files.

    No recommendation from me.

    hi,

    i’d like to know what do i need to activate trim step by step.
    it’s not about trust. i need to know what am i doing here exactly 🙂
    thanx

    Perfect, worked like a treat on my 2010 MBP with Intel X-25M SSD. Thanks!!

  36. niewiesznic 7 years ago

    Hello,
    It is not working on MBPRo Unibody 5.1, 8Gb RAM, Samsung SSD PB22-JS3 with TRIM.

    Not working also on Mac Mini 1.1 with Kingston 64Gb SSDNow V Series. 🙁

    Take care,

    P. G.

  37. Matt Henderson 7 years ago

    I installed it on my late-2008 unibody MacBook, with OWC Mercury Extreme Pro SSD 256GB (revision 310A13F0).

    Lesson learned: I should have waited for the release of the TRIM installer/enabled with the “Restore” function.

    It initially seemed to work, and the computer ran fine for a couple hours. Then the fans came on and everything beachballed. Restarted, and it ran for about three minutes before “mdworker” went mad — 80% CPU, 90% CPU, 100% CPU… whole computer beachballed again. Over and over and over.

    Fortunately I restored from a SuperDuper backup, and everything’s back to normal.

  38. lnzju 7 years ago

    >Then, when I was nearly done, a user on Macbidouille forum had discovered that you don’t even have to edit the kext, you can just remove the identifier altogether.

    as to this, could you give a the link ?

  39. xexe 7 years ago

    Late-2008 unibody macbook pro w/ OWC Mercury Pro 120gb. Works a charm (several hours uptime)

  40. Ken 7 years ago

    I’d like to issue a warning to all early-adopters of possible performance degradation with this fix until Restore functionality is added to this hack.

    TRIM: YES is not an indication of whether it actually boosts performance.

    I tested the performance before and after the patch and found out that it actually degrades performance a lot. Please be advised before applying this patch.

    Does anyone measured performance before and after the patch that shows the positive change? In my case, it was the other way around.

    Be careful!

    Applied TRIM enabler to Samsung SSD 64 gig.
    Ran XBench multiple times in multiple settings, ie, other applications running and just boot up. Saw really no performance degradation, but a slight increase. Xbench performance varied a lot during the course of spot testing throughout the day.

    Actually, had Samsung SSD for about 6 months, and saw NO performance degradation even without TRIM support enabled over that time, unlike some Windows users.

  43. Chris 7 years ago

    Okay, I just contacted Wintec’s technical support and they stated that their Expresscard SSD was not capable of the TRIM command! I also asked, whether it uses garbage collection or not. To this one, they did not respond at all! That’s ridiculous imho…

    Just thought i’d mention this to anyone who was in my position when considering this update…

    I just ran this prior to an ‘erase free space’ command on my 2010 2.4GHz 13″ MBP with an intel x25-v installed in the optical drive bay with no problems.

    System profiler also says that TRIM is enabled.

    Stats from Xbench show exact figures experienced when i tested the disk out of the box (and after a firmware update) i.e my disk is back to its former glory of snappy boot times and application loads.

    Thanks Oskar!!

  48. bobics 6 years ago

    have a Late 2008 15″ Unibody Macbook Pro with a 120 GB OCZ Agility 2 SSD. Here are my XBench results (best of 2 runs after a reboot):

    220.62 – initial reboot of my stock system
    246.93 – upgraded my OCZ firmware from 1.20 -> 1.32 (latest)
    242.97 – ran TRIM tool 1.1 (latest as of 3/29 12 AM PST)
    232.71 – after zeroing free space
    233.94 – after running terminal commands
    234.51 – after removing TRIM tool

    It looks like zeroing free space caused performance to degrade, and as you can see, running the terminal commands after that didn’t help.

    Since running the tool didn’t seem to help (and may have made things worse), I’d rather avoid the voodoo of enabling a feature Apple intentionally left out. It appears the Agility 2 has garbage collection anyway.

  49. ikir 6 years ago

    Works but sometimes it seems my Mac freezes for 1 seconds after this patch. Pretty strange.

  50. josh 6 years ago

    Hi

    I ran the installer and now my macbook wont boot after restart – it sits with the spinning gear at the grey apple logo screen indefinitely. Tried safe mode boot also but no luck. Any ideas on how I can get it back to functional? I made a backup with Carbon Copy Cloner beforehand so haven’t lost any data but would rather avoid having to do reinstall. SSD is 60GB OCZ Vertex (not sure of firmware version but bought it about 2-3 years ago).

  51. Matt Henderson 6 years ago

    @josh — You shouldn’t have to “reinstall”; you should be able to use CCC to simply restore your MacBook’s startup drive from your backup. If CCC works like SuperDuper, it’ll do a “smart” update; only updating those files that are different/changed.

  53. r00fus 6 years ago

    I did this with a MBP 2010 13″ and Vertex2 60GB.
    Everything went fine (did superduper before, and also used TRIM enabler’s backup feature).

    Same speeds before and after the TRIM.

    I think lots of SSD chipsets like Samsung’s and the Sandforce chipset already have native garbage collection, so TRIM (which is just OS driven GC) doesn’t really help speeds.

    However, I did get a weird “halting” issue (pause for 3-20 seconds) every once in a while (week or so)… perhaps with TRIM enabled, this will go away… haven’t seen it crop up since enabling TRIM, but it was not a common occurrence anyway.

  54. Tiger 6 years ago

    I did it following the guidance, but it did not work.

    Hi I have a MacBook Pro 15 ” (late 2008) OSX 10.6.7, I bought my Mac with an Apple SSD, the Apple SSD TS256, I try to use the last version of Trim Enabler the v. 1.1 but when I reboot my Mac if I check the System Profile I always find “Support Trim: no” Why? Anyone can give an answer about that? Have my SSD the GC?

  62. Cindori 6 years ago

    You can check by installing linux and checking with hdpharm if there are zeroes on the blocks after you delete a file in OSX (or something like that, check Trim Enabler page from the menu)

    But yeah, its been proven to work correctly as long as it says “Trim Support: Yes” in System Profiler. 😀

    Does anyone know how to uninstall the patch?

    Adam, click the restore button.

    Had it working on my Corsair F120. Writes ans reads seamed ok. But deleting was a pain. Running rm. Oa 500 MB test file was taking appr 10 seconds. After restoring the original driver things are back to normal. rm takes milliseconds while read/write was the same. I wounder if this is related to the old firmware on the drive (1.0). Maybe someone can crosscheck?

    Xbench gives funny results anyways. Never above 180MB/sec while a dd reaches 260 MB/sec. Is there a more suitable freeware check around?

    Kind regards,

    Hi,

    My Intel X-25-M 160GB SSDSA2M160G2GC already showed Trim Support: Yes before. Does that mean I don’t need this patch? How to use the full advantage of having a trim-supported ssd? Do I have to execute anything more in the Mac OSX 10.6.7? Thanks!

    Worked fine on my Crucial C300 256GB, until I tried opening my VMWare Fusion virtual machines. I tried 2 and they both were unusable – completely unresponsive, and one of the Mac’s CPU core running at 100% continuously whilst the VM was running. Strangely, I checked the SSD activity and there were no read/writes happening.

    I’ve just uninstalled it without any issues, and the VMs are back to normal. More than coincidence I think….

    how to make this work on Wintec ExpressCard 96GB? (cuz it doesnt work)

  72. Pinarek 6 years ago

    Hello

    In a original Mac (MacBookPro) and I have a PC Hackintosh.
    Tells you because maybe other friends who also have a Hackintosh, if it goes as well?

    I think it may have several causes.
    On 1 I have my SSD (the Mushkin 240GB) in 4 partitions with MBR (not GUID = GPT) formatted. I had to choose the MBR due to an existing
    Windows XP partition.

    I have tested various versions of fsck, across these 2 lines:

    ** Trimming unused blocks.
    ** The volume SSD appears to be OK.

    were not available, so it will not be good.

    By the way, you can do it in normal operation in the console access this fsck command. Only if the current partition (the working partition) will
    examine what indeed is not possible during operation, then you have it at system boot with -s after the Chameleon boot make Hackintosh PC
    with cmd+s for original Mac.

    I hav a small 30GB SSD from Kingston (a Snow-V Series), this time I will only as a GPT partition (is GUID) format it.
    Then I will again consider the tests with different versions of fsck are then whether these 2 lines in it.

    Only in this Blog you deal with the TRIM command very intense.
    In other forums where I am also member (InsanelyMac etc.), as you wrote but that there is the trim-hack, but whether it really
    works nobody knows.

    I’m 57 years old and am working for 3 years with the Hackintosh thing I have on both my PC (the one with MSI P55-GD65 Board
    and i5-650 processor and other PC with Asus P7P55EVO Board and i3-540 Processor).
    It is still running MacOSX 10.6.7 and Lion Dev. Version 1 and 2 on the two machines very satisfactory.

    If you do not have information about my problem I would be very happy if you write me.

    I am not satisfied until I really looking that the trim on my hack and my Mushkin SSD and it works on the Kinston-SSD.
    Otherwise useful but the TRIM-Hack with the only indicator in the System Profiler but nothing.

    Greetings Pinarek

  73. Cindori 6 years ago

    Hello Pinarek

    You can read about proof on the hack here:
    http://www.xlr8yourmac.com/archives/mar11/032511.html

    It does not just appear in System profiler, it actually works.

    If you can not get it working on your SSD, it either not supports TRIM, or needs a firmware upgrade to support it.

  74. Pinarek 6 years ago

    Hello Friends Cindori and unknow User

    All they linked here, I already know, I’ve already read everything.
    The test with Ubuntu Linux is the only interesting, but not instaled Ubuntu.
    Are so similar that not even for MacOSX to get a real proof for the functionality.

    I hav read in Mushkin-Forum that my 240 GB Callisto hav a SF1200 Controller and all this can IGC. And IGC is up 90% we TRIM-Support.

    My liddle Kingston 128 GB “Kingston Snow-V-Series” hav a old mix Jemicron and another Dialer Controller, an for this SSD will test in future this Trimm-Enabler1.1 again. i will formatting this 30GB SSD with only 1 Partition in GPT-Partitionstable.

    Ok i write here in next Time.

    I have an early 2008 MBP 2,4 GHz with a Crucial C300 256 GB. Trimming worked after the patch, but I realized a significant decrease in starting programs and also some “freezing” for 1-2 seconds while scrolling. In addition it worked very bad with my Parallels virtual Win XP (caused some blue screens).

    Was worth a try, but finally I restored my backup and live with Crucials Garbage Collection again.

    it worked perfectly on an iMac 27″ with Kingston V+ SSD. Even VMware makes no problem.
    It works on an MAB 11,6″ 64GB but only after a save start. Afterwards it works perfectly.

  80. Dan 6 years ago

    I’m not sure if the TRIM function of this program works (I assume it does based on other comments and my trust in the developer). But it sped up my bootup time by about 2.5X what it was when I installed my SSD without TRIM. I have no idea why, but it fixed my SSD, even though it was installed the same day.

    Thank you so much for this enabler.

    Trim Support Enabler v1.1 worked spectacularly for me and my equipment:
    MacBook Pro 13″ mid-2009 2.26 GHz, 4 GB RAM, OWC Mercury Extreme Pro 120 GB SSD. After enabling trim, secure erasing the free space, and using the 3 Terminal commands listed in the posts above, I rebooted the MacBook and found to my surprise an tremendous increase in boot speed. After initially installing the SSD, my boot time improved as measured by the gear beneath the Apple logo revolving about 14 times (as opposed to about 30+ times with the original 160 GB hard drive). After enabling Trim support, the spinning gear only requires 5 revolutions in the boot process, about a 3 to 1 improvement. I still can’t get over the improvement. Thanks for all your hard work to bring this feature to Mac OS!

  84. Travis 6 years ago

    Just a heads up for anyone in a similar situation as myself. I’m running a OCZ Vertex 3 SSD on an early 2011 13″ MacBook Pro 10.6.7 and although TRIM Enabler 1.1 worked to enable TRIM, it caused occasional beach balling that varied in duration from approximately 10 seconds to as long as 30 seconds. The laptop would also permanently beach ball when resuming from sleep.

  85. Raymond Uphoff 6 years ago

    Guys… My hackintosh was also suffering in performance decrease after running TRIMEnabler, but…. today I uninstalled a kext and regenerate kext cache files. now shutdown and systemboot is seriously faster. I don’t know the voodoo.kext was the problem or regenerate mkext was the solution.

    By the way I used pfix 3.1 for regen kext-cache.

  86. benFnord 6 years ago

    Didn’t work on my:

    MacBook Pro 7,1 (13″, early 2010) with
    OCZ Vertex 2 240GB, firmware version: 1.11

    This may be due to the old SSD firmware (current version: 1.33), which I have to use since newer versions result in 30 sec. hangs of the whole system.
    Luckily, I backed up the kext and was able to copy it back while booting from the install DVD. Thank you for implementing that backup feature, Cindori! 🙂

  87. Régis Derimay 6 years ago

    Hi there,

    I am experiencing exactly the same problem as Travis (comment 133).
    Installation worked fine but caused a major performance decrease and beach-balling especially when coming out from sleep or sometimes when heavy actions where running.
    Uninstalling solved the problem.
    Any advice would be greatly appreciated.

  88. MikeB 6 years ago

    Hi, just to let you know guys that I discovered a strange thing. I use an app called Softstep (made for a midi footswitch of the same name). Well, this app refuses to load whenever TRIM is enabled. As soon as I ‘restore’ (thanks for this new option) the app works again. Any idea ? Is the app allergic to Trim or it doesn’t like a .kext to be modified ? I guess there must be a way to make it believe it was NOT modified, but how ?? Thanks for your tricks…

  89. Cindori 6 years ago

    It does probably not interact with TRIM, but maybe uses a buggy driver that has some buggy permissions. Try Repair permissions in disk utility.

  90. Jon Kane 6 years ago

    I am not seeing the 3 terminal commands referenced above. Could someone please repost these terminal commands? I am running a Crucial C300 in a MBPro 13″ (2010) and I get intermittent pauses when running applications.

  91. Cindori 6 years ago

    the c300 has garbage collection and is only affected negative by enabling trim.

  92. MikeB 6 years ago

    “It does probably not interact with TRIM, but maybe uses a buggy driver that has some buggy permissions. Try Repair permissions in disk utility.”

    Thanks Cindori, of course I already tried repairing permissions, but no success.
    Well, I passed the info to the Softstep developers and we’ll see. As you said, it must be very buggy as, except this one, none of my apps I use cares about the modified kext.

    Results with Intel 320 depend vastly on the benchmark – beware!!!
    OK, I just got a 300GB Intel 320 and I’m using about 2/3rds of it.

    With xbench the results are similar. Maybe with a slight edge towards the TRIM version but it’s inconclusive. I’ve attached bitmaps of the xbench screens.

    But with postmark (NetApp benchmarking tool – used for testing heavy random I/O) I got VERY different results. I ran this a few times to make sure.

    Before TRIM:

    Time:
    16 seconds total
    11 seconds of transactions (1818 per second)

    Files:
    20163 created (1260 per second)
    Creation alone: 10000 files (2500 per second)
    Mixed with transactions: 10163 files (923 per second)
    10053 read (913 per second)
    9945 appended (904 per second)
    20163 deleted (1260 per second)
    Deletion alone: 10326 files (10326 per second)
    Mixed with transactions: 9837 files (894 per second)

    Data:
    557.87 megabytes read (34.87 megabytes per second)
    1165.62 megabytes written (72.85 megabytes per second)

    After TRIM:

    Time:
    39 seconds total
    31 seconds of transactions (645 per second)

    Files:
    20163 created (517 per second)
    Creation alone: 10000 files (3333 per second)
    Mixed with transactions: 10163 files (327 per second)
    10053 read (324 per second)
    9945 appended (320 per second)
    20163 deleted (517 per second)
    Deletion alone: 10326 files (2065 per second)
    Mixed with transactions: 9837 files (317 per second)

    Data:
    557.87 megabytes read (14.30 megabytes per second)
    1165.62 megabytes written (29.89 megabytes per second)

    I restored the original driver and it went back to being fast for postmark.

    I wonder if TRIM is interfering with the benchmark since it tries to clean up on the fly and doesn’t let the SSD do its thing. The difference is huge so I’m leaving it off…

    FYI all, I ran postmark (it’s a CLI tool) with the following settings:

    set buffering false
    set size 500 100000
    set read 4096
    set write 4096
    set number 10000
    set transactions 20000
    run

    It will randomly create 10,000 files from 500 bytes to 100,000 bytes in size, and will then do 20,000 operations on them. You can configure it any which way you want but I’ve been running like this for years (I also work at NetApp, check out blog at http://www.recoverymonkey.org where I’ve done similar testing before).

    Thx

    My XBench score went up a bit after enabling TRIM on my laptop. I tried it on a colleague’s machine with the same specs and SSD (although 4 GB of RAM) and the score went down, mainly because of slower writes. But, it wasn’t a big difference and the read scores went up a bit. The scores are pretty low overall so I think the machine’s SATA interface is a bottleneck for the SSD.

    Tried TRIM Enabler 1.1 w/ 2010 MBP + 256GB Samsung S470 series SSD.

    After some experiments, I got the conclusion that my Samsung SSD doesn’t need this TRIM enabling. With TRIM enabled, Xbench disk test scored what like 300 around while disabled it scored what like 450 around.

    Actually, without TRIM enabling, uncached read/write speed were like 250/220 as Samsung SSD specsheet says. So determined not to use this.

    I think that you can’t get the performance boost if your SSD has native garbage collection feature.

    But I wanna say Cindori did a very good job for people, especially when not many people cares about Mac hardwares.

    I’m trying to use the Restore feature of TRIM Enabler (to restore Default). The app says it was successful, but after a reboot, Profiler still says TRIM: Yes and performance is still bad.

    Any ideas on how I can manually disable TRIM? The Restore feature doesn’t seem to work.

  105. Cindori 6 years ago

    Apple SSD has TRIM enabled by default in 10.6.7.
    This tool won’t make a difference for you.

  106. Christian 6 years ago

    Before running TRIM Enabler, Profiler says TRIM Support: No and performance was good.

    Now after, Profiler says TRIM Support: Yes and performance is bad.

    I’m just trying to restore but I’ve tried it several times and it’s stuck in a bad state.

    Thanks for your help.

  107. Cindori 6 years ago

    that’s wierd.

    download 10.6.7 again from apple.com/support and reinstall. this will restore your system.

    I tried this on my Mac Pro 6 core 3.33 (2010) using a Patriot Inferno 120GB. It patched successfully, but after using it, web browser performance went through the floor (near unusable). Most other apps including FCP and Photoshop still seemed fine, but Safari and Chrome basically wouldn’t scroll a page if another tab was loading. After restoring back the browser performance is fine. Very strange.

  114. Justin Ayers 6 years ago

    Nergol,

    The SSDNow V+ 100 SSDs don’t need TRIM. They have very aggressive garbage collection:

    http://www.anandtech.com/show/4010/kingston-ssdnow-v-plus-100-review

    However, since you have an earlier model (not V+ 100), I don’t know how aggressive the garbage collection is. Anandtech reviewed a tiny 30 GB unit and said it supports trim but not NCQ (native command queuing). I assume that you should use the trim enabler with a regular V series drive like the one you have.

  115. Jan 6 years ago

    Will I have to run this again when OS X is updated to 10.6.8? Will I have to restore the original IOkit driver before updating?

    I have enabled TRIM on my kingston v+100, would this be a problem? The description on the SSD says I can use it with TRIM but I’ve read conflicting things with the mac enabler that it may actually be a detriment to use the enabler with it.

    Please let me know if keeping the TRIM enabler with my v+100 will help or hurt my system performance!
    Thanks!

    Huge performance degradation on macbook pro core i7 with crucial real ssd c300.

    Everything performed poorly, took a while to discover the cause! Youtube was jumpy, scrolling in chrome was jumpy and program launch times were reduced.

    Out of desperation tried uninstalling and found an instant fix! 4 weeks of annoyance solved, the issue did not arrive immediately, hence the difficulty in finding the problem.

    I say, wait for Lion to implement TRIM, this tool did not work as expected.

  118. Cindori 6 years ago

    dont install patches just for the fun of it, if you have an SSD with aggressive garbage collection (like C300), TRIM is not for you.

    Ultimate Question:
    If I want to know my SSD have an aggressive garbage collection, when I SEE?? In whats specs?!
    Then for my SSD the TRIM is necessary?

  122. Alfr3d 6 years ago

    Cindori thankz.
    But I don’t found anything!! 🙁
    In this link: http://www.ocztechnology.com/ocz-vertex-2-sata-ii-2-5-ssd.html specs.

  123. Alfr3d 6 years ago

    Ehm Thankz.
    I’m not a newbie in this situation.
    But at this time I don’t found anything.
    It’s no difficult search in google.
    Difficult is UNDERSTAND anything for this technology (SSD).
    Now , with this GARBAGE COLLECTION, I setup TRIM ON or OFF?!

  127. Patrick 6 years ago

    I have been running OS X 10.6 with a OWC SSD for a few months. I was concerned about the slowdown. After contacting them, I found that they have a very well supported aggressive garbage collection feature built in that you should leave TRIM support off 🙂

    After three months of HARD use on a drive with less than 10 percent available I get 129MB/s Write and 110MB/s read. This is what it has been from day one. Not as fast as some, but no change in performance is key 🙂

  128. Joeeeeeeee 6 years ago

    Does TRIM support Lion??

  131. Promethean2 6 years ago

    TRIM is important for long term performance with new CRUCIAL M4 as garbage collection is not as aggressive as has been seen on other drives.

  132. Vendini 6 years ago

    What about a Lion’s version?
    The GM version doesn’t activate TRIM by default for all SSD, so we need your help!

  133. Jeppe 6 years ago

    Apparently this seems to work better with Intel SSDs. Is it because Intel does not use a Sandforce controller for it’s SSDs? I’m planning on buying either an OCZ, Corsair or an Intel, but it seems like the Intel would be the better choice if it supports TRIM, even though Intels SSDs are slower in general.

  134. TeeJoe 6 years ago

    I just installed an OWC Mercury Electra 6G in my mid 2009 (2.53GHz) Macbook Pro. My Xbench disk test score was previously 265, and now it scores consistently over 300.

    But just anecdotally, my applications load significantly faster, especially the Creative Suite applications. And the reboot time dropped significantly.

    Thanks for the app, very helpful.

  135. kidtreo 6 years ago

    Wow lots of speculation…can anyone actually confirm for sure that Trim Enabler is GOOD for 10.7 with Vertex2 firmware 1.33? Thanks!

  136. Nick Donaldson 6 years ago

    Just did the patch! Worked perfect no problems. Seems to be quicker, used to have the wheel quite alot not now. Thanks to the developer! Wow!

  137. Jeppe Thegen 6 years ago

    I tried this with an OCZ Agility 3, and the results were quite similar to the ones without TRIM. I’ll keep using it, due to the fact that it increases the lifespan of the SSD.

    Thanks!

  138. BMAG 6 years ago

    Has anyone tried it on Lion 10.7? I just upgraded my Mac which has an Intel 320 and it shows no support after reboot…didn’t want to be the first. 🙂

    Just installed Lion (release version) to my MBP 2011 with Intel 320 SSD, it is so sad that no TRIM is supported.
    So I run the SSD Enabler and now show TRIM is supported. Unforunately I forgot to back up IOAHCIFamily.kext 🙁

  140. Some Random Guest 6 years ago

    Same here:
    Lion + Intel 320 SSD = No Trim support 🙁

    But I took the risk and:
    Lion + Intel 320 SSD + TrimEnabler = Trim support 🙂

    Thanks for keeping my SSD in a good shape.

  141. Fabian 6 years ago

    Lion+Intel 320 SSD + TrimEnabler seem to work for me too.

    MBP6,2 + KINGSTON SNVP325S2512GB (TRIM off) + Snow Leopard. Xbench Sequential: 180.68, Random: 538.61

    On a Kingston web page, I found this:

    If you use one of our drives that have effective garbage collection (SVP100, SVP100E, SVP180, SNVP325), you will not see any significant performance decrease in non-TRIM supported configurations.

    In view of their (double negative) wave-off, I will leave TRIM disabled.

    a) Crucial C300 doesn’t have aggressive Garbage Collection, SF1200 has it but Crucial use Marvel controller and is famous for his performance on 4K but also for the loss performance on long time.

    b) for who use Lion and can’t use ‘Erase Free Space’ in Disk Utility: with trim enabled fill with file the SSD and after delete it, if all works fine it should -trim- 😀
    For example in terminal with ‘dd’ fill free space with zero (/dev/null)

  159. Alamgirian 6 years ago

    Hey guys… The Patch was working beautifully in Snow Leopard. I have Intel 120GB G2 SSD.

    However, since upgrading to lion, if I open a torrent client, it crashes my system to white screen. Earlier today, it crashed my system without even opening the torrent software (this has just happened once). But with torrent software (vuze or bittorent) it keeps crashing my system.

    Some help. Should I consider clean install of OS Lion (foregoing time machine) and manually just backup data…. or is it that my Hard Drive needs replacement from Intel ?

    Thanks in advance.

  160. nanofunk 6 years ago

    the trim enabler worked fine, although the Console.app Messages kernel[0]: IOSurface: buffer allocation size is zero were appearing much more often than without TRIM enabler. can this issues be related?

    If I apply this to a RAID 0 stripe (using Disk Utility) of 2 x 115GB Vertex 2 drives, will it work? Does TRIM work across a RAID volume?

  167. Duke 6 years ago

    Works, but system occasionally hangs for several seconds. Seems to only happen when using Safari, not sure though. I get same errors as nanofunk. I uninstalled Trim Enabler, or rather installed the old kext and I have no freezing issues. 2011 27″ iMac i7. OWC Electra 120GB.

    I installed TRIM Enabler on my MacBook Pro running Lion (10.7) and on my iMac also running Lion. I installed Crucial’s m4 SSD on both machines, then discovered that they have built-in automatic garbage collection and do not need TRIM.
