It's the first time I see that an user deletes the OS X kernel by mistake. Be more careful the next time.


As you made a Time Machine backup before, it's easy to recover all your files:


1. Insert the Mac OS X Leopard DVD and press the C key while your computer is starting to start from the DVD.


2. After the disc has started, go to Utilities menu, choose the option to restore the backup and follow the steps

Is there a way to do it without starting from the DVD? My disk drive is broken. Will I be able to hook up an external disk drive and boot off of that? The reason I was doing all this was because I was trying to upgrade my operating system and accidentally bought a mac super drive. I found a workaround on the internet to use it with my mac book, but i accidentally deleted mach_kernel.
