TRIM Support Enabler 1.1

TRIM Support Enabler 1.1
March 28, 2011 Oskar

Whats new:

  • Fixes problems with long boot times
  • Restore driver button
  • Backup driver button
  • Automatic updates

Will add a page for TRIM Enabler explaining the app…


Did you already patch and don’t have backup to restore?
You can try using Restore and selecting Default driver.

    How about a download link for 1.1?

  2. Cindori 8 years ago

    there ๐Ÿ˜‰

  3. beefcoder 8 years ago

    Thank you. Lets test it. ๐Ÿ™‚

  4. Roman 8 years ago

    Thank you very much, the restore with the default drivers worked ๐Ÿ™‚ Speed is back to me and my ssd!
    Regards, Roman

    How about a message that the permissions repair is done?

    It is a litte confusing seeing that spnning wheel on the one hand and the reboot message on the other hand.

    beef: not really sure I follow, can u screen?

  7. Christopher 8 years ago

    The new patch works for me. Long boot times with 1.0 and Intel 510. With 1.1 only 15 seconds boot time. Good job ๐Ÿ™‚

    Way to go Oskar! Can’t wait to try it

  9. Weust 8 years ago

    Backup, patching and restore seemed to work alright on this MBP from 2009.
    Restored because the BTO SSD does not support TRIM at all.

    Will try it later in my Mac Pro with a Vertex Turbo. At least I know that one has TRIM support and shows it in the “About this Mac”.

    Happy to finally see TRIM support on Mac OS X. About time ๐Ÿ™‚
    Thanks for the application.

    Works great on Macbook Pro 13″ MC374 with OCZ Vertex 2 120 Gb fw 1.32. Thanks for the utility.

  12. Glen 8 years ago

    MacBook Pro5,1 and NVidia MCP79 AHCI with Apple SSD SM128 don’t work

  13. Cindori 8 years ago

    Apple SSD SM128 does not have TRIM, sorry.

  14. Glen 8 years ago

    Ok no problem ๐Ÿ™‚

    But I like your work!

  15. Thibaut 8 years ago

    It doesn’t seem to work on my Hackintosh with a Kingston SSDNow V Series 128GB. Vendor says it supports TRIM but maybe it’s because of the Hackintosh ๐Ÿ˜‰

    Motherboard is an Asus P6T with minimal kext patching; downloaded and installed the 2.0.5 IOAHCIFamily.kext then patched. Doesn’t break anything but system profile still reports no TRIM support.

  16. Stefan 8 years ago

    My Macbook hangs at boot now ๐Ÿ™
    I have a Supertalent 120GB SSD installed.
    I tried to move the backuped kext to System/Library/Extensions manually by booting the OSX install CD, but no luck.

    Any Ideas?

  17. rufrei 8 years ago

    Same as Stefan on mini. It got solved by booting an external drive and reapplying the MacOX 10.67 single update. Then booting into Install-DVD
    (changes the System from Time to Space) and doing a Rights-Repair.
    Booted into the mini OCZ-Vertex 2 and trim support was there.

  18. Stefan 8 years ago

    fixed it, by moving the backuped kext in place and doing a repair permissions afterwards. but no trim for me ๐Ÿ™

  19. beefcoder 8 years ago

    @ cindori

    I have been testing your new version for some hours now and it seems to be good. Thanks mate.

    What I meant above was:

    When I use your tool, it repairs automatically the disk-permissions before it opens a window saying “patch applied, restart”. During this process it shows a spinnig wheel continuously (like on the start of Mac OS – the grey window)

    What I try to explain is, that it could be helpful to see a message when the permissions were finally repaired. The wheel keeps spinning and spinning and spinning and you don’t know if it was finished or not (without opening the acivity monitor)

    I hope it helps.

  20. Ken 8 years ago

    My initial trial was not very successful. However, I can report that after restoring the system to the original state using the restore functionality, updating the SSD firmware to the latest one, and re-applying the patch with v1.1 actually increased the performance by about 5-10%.

    Thanks for the fast update!

  21. Pierre 8 years ago


    Does not seem to work for me with an Intel X25 Postville 80gb, still says Trim NO. Restored previous driver, everything is ok. Questions:

    – I get the feeling that this does not work with 64bits kernel … could that be the problem ?
    – Does anybody know how to upgrade the firmware of an Intel X25 on a Mac ? all firmware tools are for Windows …

    Thk. Pierre.

  22. beefcoder 8 years ago

    @ Pierre

    Here you go:

    go to the Intel support downloads page;

    choose Solid State Drives and Caching;

    choose your disk;

    download Intelยฎ SATA Solid-โ€‹State Drive Firmware Update Tool;

    burn this ISO (it is bootable);

    think of your latest backup before flashing the disk!!!

    start your mac from the Intel firmware disk; follow the instructions. you don’t need windows

    the update utility doesn’t work with optibay-drives

  23. Lol Gatto 8 years ago

    Thanks a lot for very useful utility. I’ve just installed TRIM Support Enabler 1.1 and feel much worth, yet without measurements. I have my 10.6.7 on Kingston 128 Gb SSD (besides other HDs) and i7 6-cores processor, so it need fast respond to fulfill its cores. Having my new comp not for a long time I didn’t know about TRIM at all. My respect to you, young man!
    Now I wonder, does patching the kext affect ALL SSD disks I might have — OR, e.g., only my boot drive? If I make this patch on a boot volume not on SSD disk, may such kext replacing have negative effect on the performance anyway?
    Thank you in advance, good luck to you and your work!

  24. jlzhou 8 years ago

    It works fine on my MBP374 with Intel SSD 120G G2 INTEL SSDSA2M120G2GC.

    Good job! Many many thanks!

  25. Eddie 8 years ago

    Seems to work fine with my Crucial C300 256GB on my 2011 i7 15″ MacBook Pro 2.2GHz 8GB ram.
    So far so good, hate mail to come should it go haywire ๐Ÿ˜›
    let’s hope not.

  26. Klausmac 8 years ago

    Super!!! Thank you for the work done.

  27. Robert 8 years ago

    it is normal that speeds go back but this is only in the first time let it run for a while then the speeds should return. it like a harddisk defragemtation. you don’t do a speedtest for hd while you run a harddisk defragmentation. i let mbp on for 3 hours i got same speeds as before. i got a ocz vertex 2 version 1.32

  28. Pierre 8 years ago

    @beefcoder: thks, so that’s another project … I have an Optibay ๐Ÿ™‚

    @cindori: does TirmEnabler modify both the 32 and 64bits kext or just the 32bits ? I am not even sure that both do exists but I am reading evrywhere: “A 64-bit Kernel can load only 64-bit kexts (kernel extensions).” Here for example: (because of course I am booting 64).

    Thks. Pierre.

    worked on my macbook pro 1,1 and INTEL SSDSA2M160G2GN

    pleasantly surprised

    Man, just wait for Lion 10.7, should be by summer time.

  31. adnium 8 years ago

    Just restored using 1.1 utility having previously enabled TRIM with the 1.0 release. Under 1.0, the machine would take about 14 spins of the Apple “gear” at startup to boot.

    Re-patched under 1.1, this now takes about 3, which is still slightly longer than before un-TRIMed, but speeds are roughly what they were pre-patch after 1.1.

    I noticed that Trim Enabler 1.0 was more efficient than 1.1. I used Xbench to verify my SSD performance.

    I use Lion preview.

    I’ve restored the default driver and after a reboot re-patched.

    1.1 worked with a WDC SSC-D0128SC-2100. Not yet sure about speed improvements, but System Profiler does report that TRIM support is enabled.

  34. Aelisium 8 years ago

    1.1 working on MBP, 1.1 with 120 GB OCZ Vertex 2 SSD.

    You rock dude! You have no idea what a terrific service you have offered all those running SL. Boot up speeds are insane! Just amazing! I can’t believe what a difference TRIM makes… I am blown away… truly.

  35. plans 8 years ago

    My OCZ vertex II 240Gb was patched fine but then my system began to hang even after multiple restarts. I reverted. Not sure what went wrong here.

    I love this tool Oskar – perhaps I did something wrong on my end.

  36. staywolf 8 years ago

    I can’t unZip the ? Why …

  37. Cindori 8 years ago

    Perhaps your download is corrupt.

  38. Simon 8 years ago

    Used SuperDuper to back up the Macbook Pro. Then ran 1.1 without problems. So far solid as a rock.

    SSD is a vertex2 240G

  39. dobuzz 8 years ago

    Since the performance on my mac (after applying the patch version 1.0)
    is fine but read about version 1.1 “should be better”:
    What was changed and how (if at all) would I benefit from it?
    โ‰ˆ Versionhistory would be appreciated ๐Ÿ˜‰

  40. Cindori 8 years ago

    The version changes are listed in the post above.

  41. Cindori 8 years ago

    If you are experiencing long boot times then you should patch with the new version
