A bit of a tangent but... are you sure?

I just replaced a dead drive in an old Mini with an SSD, then installed Yosemite. I'm not really an Apple guy, so I was not aware that Yosemite implemented kext (driver) signing, which had the side effect of 'breaking' TRIM support for 3rd party SSDs. It was never supported to begin with, but prior to Yosemite you could enable it by changing strings in the kext; doing so now will render the Mac unbootable unless you globally disable kext signing. Apple does not offer any other ability for a 3rd party to write their own driver to make this work, short of possibly rewriting the entire AHCI stack, which is not feasible.
