Mac OSX 32 64 bit kernel boot command

last week, I launch a article about 64 bit kernel booting.

But I found a command today to set up kernel easily form the Apple official site.

#sudo systemsetup -setkernelbootarchitecture x86_64 


#sudo systemsetup -setkernelbootarchitecture i386



These two commands can set the kernel model type, after you restart your Mac using uname command in your terminal to check your kernel mode.                                                                            


#uname -a


If your terminal display the mode that you set, you set up successfully.
