Just letting my readers know that , the patched kernel for old AMD and intel users (pre Core series). nawcom has created an installer that would just do that for you. You may download it from here. Please make sure that you’ve followed my updating OS X Guide first if you are about to update 10.6.x to 10.6.4 .
The good news about OSX 10.6.4 is that now we have variety of support for Intel Core i series and not to mention new drivers for the onboard Intel card. I’ll update EmpireEFI in the upcoming weeks to enable support from booting from OSX 10.6.3 DVD with the new stuff. Be prepared for that guys !
Changelog after the jump !
