Hello,
I followed this tutorial using mountain lion, thus I did not follow the additional steps. I have gotten the OS to boot in virtual box however its totally broke. I cannot run sudo in terminal, I get a error "sudo: unable to cache user root, already exists".
I try to install an app from a dmg but it asks me to authenticate with name and password - I enter my name and password and it doesn't work. I even changed password in system and still didnt work.
