I would like to change a user password for a guest installation of Snow Leopard Server.
I've looked around, and found that one proposed solution was to hold Command-S after the chime. I tried several times, and never had it boot any differently.
I have the installation disk, and it's a guest on OSX High Sierra.
Thanks to @Tetsujin's kind help, I got in Single User Mode.
But if this is Single-User Mode, it's the most noop of a Single-User Mode I've seen in any Unix. The text appears clipped, although that's tolerable; what I don't understand is that none of the commands generate any output besides the shell giving another prompt.
I started to try to mount the filesystem to change the password, but this seems a broken Single-User Mode. Is there anything else I should be doing to get a Unix command line?
