The kext posted is like a driver with support for TRIM so it will not work only if there is something else that break it. I think that on 10.6.5 it could work. If I can I'll try it on 10.6.4 but before I have a lot of other works to do.

P.S.:
I belive that Magnifico sad that because of the subtitle of this topic, for what I know he doesn't have a 10.6.5 build to test it.


I have installed the 10.6.5 on the clone, does not work , but because you have fear of Apple store?

:unsure: :)

This is great, too bad I don't have an SSD :/. I have one in an old mac running leopard, wish I could use it on that.

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.

eMatoS .. I know what you mean, I've also read
Perhaps the professional developers will find a way to get the right to test

My Mushkin 256GB SSD and 128GB SSD run my Kingston
no obvious errors. I hope it will suffer the SSD memory do no harm.

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.

Remember, if your SSD has garbage collection in the firmware, it was probably already doing a reasonable job of optimising performance without Trim.

Listens Scrax, but can be made a script, for the future of the kext? Instead of the commando from finishes they?

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.

do not use this tool, it will slow down your Snow/Lion System ... I tested this on 128GB SSD C300 and 64GB SSD OCZ ...
