After upgrading to Snow Leopard (OS X) 10.6.2 from 10.6.1, I found that my system could not boot, no matter what option I chose at the boot prompt (-x, -v, -s etc). After trying for nearly half an hour, I was about to give up. Finally, I tried replacing the kernel and it rocked! I think I should share my solution here because I couldn’t find something like that on Google.<\/p>\n

What I did:<\/strong>
\nReplacing the kernel of OS X 10.6.2 by OS X 10.6. You can find the old kernel from your backup (if you have), or from the Snow Leopard installation disk.<\/p>\n

Steps:<\/p>\n

    \n
  1. Grab your OS X 10.6 installation disk.<\/li>\n
  2. Boot the system using the external DVD-Rom or USB Flash Drive.<\/li>\n
  3. After booting to the installation screen, select your language and continue.<\/li>\n
  4. Open Terminal<\/li>\n
  5. Type the following:<\/li>\n<\/ol>\n
    cp \/mach_kernel \/Volumes\/XXX\/<\/pre>\n
    where XXX is the name of your system directory. If you are not sure how to find it, you can try to run:<\/p>\n
    df<\/pre>\n
    Warning(Side Effect):<\/strong>
    \nWhen the system upgrades to OS X 10.6.2, it upgrades both the kernel (the brain) and the apps (the body) to 10.6.2. Now, we are downgrading<\/strong> the brain back to 10.6. It may cause unexpected behavior because the brain and the body are speaking different languages. You can think about the problem this way: The brain is speaking an old language while the body understands the new language only. Will they get along together? May be. Only Apple knows the answer.<\/p>\n
    So do it at your own risk.<\/p>\n
