Update at your own risk and feel free to post "About This Mac" screenshots when you've updated.

From his README:

READ Carefully !!!!

1- install comboupdate ! don't restart !

2- install kalyway kernel pkg ! choose kernel you need for your pc ! (if you want keep your old 9.2 kernel so install this pkg without selecting 9.3 kernel !!!)

if you stuck at bsd root after reboot ! so type "update -v" without quote at f8 darwin prompt ! it should work !
