I’m unable to reach the GUI bit of the OS X installer in VirtualBox. It keeps getting stuck at the Shell/Terminal text. For the ISO, I have the installer .app. I went in and found the InstallESD.dmg file and then converted it to .cdr, and then .iso. I’m not sure what I’m missing here. No issues with Snow Leopard. I’m thinking maybe there’s some additional steps since I’ve never tried with a non disc version for VirtualBox.
