The guide on O’reilly Network covering howto bypass the OS X GUI doesn’t seem to work on 10.4.x (I haven’t verified it on previous versions yet), as the guide mentions you need to uncomment the first
console entry & comment out the second entry in
You then need to goto
/etc/mach_init.d/ & remove
I highly recommend that you move the file into somewhere else instead (I moved mine into
/etc as it’s alot easier to roll back).
Once you’ve rebooted & logged in you should find that the system stays at the shell instead of jumping to a blank blue screen with a cursor.
