Most kernel extensions are signed, because OS X developers can easily
sign their extensions with an OS X developer certificate. The glaring
exception is a third-party TRIM enabler kernel extension which hasn't
been signed by the developer, and therefore will not load on machines
running 10.9+. And OS X 10.10 comes with built-in TRIM support which
means that extension is no longer necessary.

Disabling kernel extension checking in OS X is *extremely* bad advice to
give other OS users who may not know the implications of doing so -
especially considering TRIM support is built into OS X 10.10.

There's no need for most people to disable it.

You've been shown to be wrong in the past about this, and you are just
as wrong today. The fact is TRIM isn't necessary with modern SSD models.

Also, OS X 10.10 has built-in TRIM support which means the particular
unsigned kernel extension that you seem to love so much is *not* needed.

> And Yosemite only enabled TRIM for APPLE branded SSDs.

As usual, you are wrong. OS X 10.10 has built-in TRIM support for *all*
SSD makes and models. The unsigned kernel extension you seem to love so
much is *unnecessary*.

Wrong as usual. The utility is built into OS X 10.10.

There are no unsigned kernel extensions other than the useless TRIM
enabler you seem to love so much.
