What keystroke combination will allow me to boot into a Unix prompt upon startup?

Thank you!

    Provided open firmware protection is not enabled you can log in as root by holding down Command-S when you boot. Refer to this article for more detail.

    Why do you want that? The computer is not usable in text mode.

    Also note that "You cannot enter single user or verbose mode if the computer owner or administrator has enabled Open Firmware Password Protection".

    Hi Ken,

    > It is to those who know what they're doing.

       Yes and Mihalis is one of the absolute best there is. Fortunately for us, he's also one of the most helpful; check out his posts on the Command Line & Terminal discussion.

       Mihalis is also correct that despite the power of the command line, in single user mode without any services started, the computer is a mere shadow of what it can be. Remember that according to Sun, "the network is the computer." Mihalis could be trying to determine what Carla means by "boot into a Unix prompt upon startup." It could refer to single user mode or it could inaccurately refer to the ">console" login. (Does that still work?) If it really refers to single user mode then it probably indicates a problem to be solved and Mihalis could be trying see if we could be of assistance with the problem.

    I'm sure he is, but to say it is unusable is a little over the top, wouldn't you agree?

    Gary was right about what I was thinking. Gary, thanks for your kind words.
    Also, if someone cannot find how to boot into single user mode, it is unlikely that he/she will know how to use it.
    My opinion is that Carla whats to boot into text mode (linux uses it a lot) but not in single user mode.
    Ken, you are also right that the system is not unusable, provided that you know what you are doing.

    This is what I hope comes in Mac OS X 10.5, however I'm pretty sure the chances are slim to none.

    Yes, you're both right--I was unclear about my intentions because I was a little confuzzled about my iBook's bad attitude at the time.

    I meant both: single mode, and literally text mode; the latter as in a boot loader, like LILO or GRUB. I could have sworn that that ability was built into the system (being BSD and X11), but I was wrong, methinks.

    I do know my way around single-user mode, which is the term that was escaping me, and therefore the reason I was so unclear. I apologize. I couldn't remember the name, let alone the keystrokes.

    So, I apologize: Command + S is my friend is the answer to part 1; nope, to part 2.

    This is what I hope comes in Mac OS X 10.5, however I'm pretty sure the > chances are slim to none.


    Would be nice. However, the rumors (?) I've heard are that that point will be moot for me, since 10.5 will apparently be leaving the G3 behind. Oh, well.

    Thank you all for your help. Sorry about the confusion--I'm a technical writer by profession, I know better!

    Hi,

    Long time PC user who's brand new to the Mac World. I'm trying to boot to the terminal prompt. I have a Logitech keyboard. What key substitutes as the Apple/Command key? Thanks!!!
  • mjcotter Level 1 Level 1 (0 points)
    Found it. It was the Windows key. I tried it initially. Guess I didn't let go of it soon enough.
