Apparently works perfect here on both my hack in rig and my girlfriend's macbook pro mid 2010. Both have OCZ vertex2E 60gb (the last ones with 25nm architecture) and 10.6.7 snow leopard.

p.s. now that we have a patched kext it is necessary to install it in S/L/E or maybe in the future we can use it also in e/e??

As always.... thx for this hack!

regards, stefano

There's no way to check on osx for now. I've read somewhere that it actually works and proved it by removing a file and then checked with linux if there was some trace left of the space where the file was and there wasn't (something like that :D)

 

BTW, the fix worked with my Corsair F60.

this is a patch that need to be done to an Apple kext, and is not a plist mod that can be achieved with a dummy kext, so yes it needs always to be in S/L/E/ because it need to overwrite the original one and because it has some dependencies that /extra can't solve.

 

BUT in future you can just use the terminal code to patch the "already in SLE" original one.

Intel SSD 320: (80Gb)

 

Works fine with H55M-UD2H, xBench gives 260 before and 300 after trim activation.

 

On G31M-ES2L however, the status does not show up at all, and after some research it looks like ich7 doesn't really support trim, or you need some special windows drivers. Too bad.

It would appear that generally ICH7s are OK, from this Intel link: Intel ICH Features

 

Anyway MBP2,2 with ICH7-M and Intel 320 is showing Yes for TRIM support here.

Ran the terminal command on 10.7 (11a511), and it appears to have activated Trim for my G.Skills Falcon2 and OCZ Agility3 disks. A bit early yet to report beyond that. Thanks for providing it.

Damn, I had no idea GA-G31M-ES2L didn't support SSD? I just bought a Intel X25-M G2 disk and when checking disk info the Protocol says ATA and not SSD as others, and running Trim Enabler doesn't do any difference, Trim doesn't even show up as "No".

 

Any more experience to share?

Thanks!

Yep it's good to go. You'll most likely see TRIM support unless your drive somehow doesn't support it, your mobo doesn't support SSD's or if you RAID em.

 

sweet

thank you Sir :)

 

10.6.8 keeps hanging on my SSD, with or without the TRIM enabler

guess i'll stay on 10.6.7 in the meantime.

 

Question; does this tool work for Lion, or is it not needed over there?

 

thanks

konsole says TRIM ON,

trim says NOT WORKING,

sys profiler says TRIM NO

 

version 2 beta 4.0 on samsung 830 64GB, rebooted,

 

so i did it the manual method, edited the kext in hexeditor

(APPLE SSD replaced with the name of my drive (first 9 digits))

and it works.
