memo: Trim Enabler on Yosemite

メモ

 

Kernel Extensionは署名が必要になったけど、TrimEnablerは署名されていないので、OS側を無署名でも動くように設定を変える。

sudo nvram boot-args="kext-dev-mode=1"

再起動して1分ぐらい待ってから

$ sudo kextcache -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions

Invalid signature とか言われてるけど大丈夫かな?
ここでも再起動させれば、TrimEnablerが動くはず
