Overview of Single user mode: Think of DOS in 1984. Or Apple 2 computers.
More details: Single user mode is the mode where UNIX operating systems only have access enabled on the console and have just enough processes running so a sighted person can interact with the computer. If there are additional disk drives, network connections they are not started. Essentially when the operating system startup gets to the point where daemons are started it does not start those daemons but instead starts up a UNIX shell. When the UNIX shell is exited with command-D, then the rest of the operating system startup will be processed. It is really only useful for running some specific utilities. In older UNIX systems where it was essential that there be multiple Disk drives present then when one of those essential disks failed automated boot checks the UNIX system would come up in single user mode. -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
