Default Booting to single-user mode - 03-19-2009, 03:31 PM

Greetings and thank you all to those who made this possible (and particular thanks to mechdrew, who wrote the instruction set that got me around a number of gotchas).

Now that I'm installed, I naturally want more RAM, but equally naturally, I want to make sure it's working correctly. Memtest has been my ally several times before, providing iron-clad evidence to RAM sellers that I have a bum stick. But to use memtest properly, you have to boot into single-user mode. There are many references to doing so on this forum.

But none of them tell you how to do it.

Doing a normal start with Command-S held down gives you the Dell splash screen, then the Darwin/x86 boot page with various options to follow "boot:" Pressing Enter takes you right into OS X, while using the -v switch brings on an attack of verbosity followed by OS X. Typing ? and Enter yields nothing.

Elsewhere someone suggests that the right way to do this is with one of the options from This is doubtless the "right" way, but I want to do this the familiar way.

What should I be doing to get into single-user mode?

I believe the (important) boot switches are as follows
-v Verbose
-f Force kext load (ignores kext cache)
-s Single user mode (terminal, no gui)
-x Safe mode (loads minimal kexts, includes gui)

Thank you - the -s switch did the trick. Memtest is running now (and this memory was obviously made on a Monday - string after string of errors).
