which will let you run /sbin/fsck -fy without your osx disk! Even with a password.
sudo nvram boot-args=-s
this will add a string to your firmware that sets osx to single user mode.
sudo nvram boot-args=
This will remove it. These are the only two commands you will need and for fuck’s sake,
write down the second one or you’ll be shit up the creek without a paddle when you reboot
from this blog and forget how to change it back and can’t get here to find out.
