The installation VodooHDA.kext on some systems is a example of a kexts that may make your system to not boot. Accreditation: Giorgio Multi post found here. Wiki post found here. Edited by p.H and Rampage Dev Method 1: Mac OS X Using Single User Mode Part 1: What Is Single User Mode.
'Single User' is a boot mode, you actually tells the unix shell that the OS should load only prompt (no GUI), and the local console login is the only login available (can't be logged on from the network),- In 10.6.x, if the drive is connected prior to booting into single-user mode, you need only mount it as usual ('mkdir' and 'mount' lines, above, modified to reflect the ID of your drive). An aside: the reason I wanted to mount a flash drive here was to be able to run a shell script that reset a clean install after initial setup/login/updates.
- Replace 'name.kext' with the name of the kext you're installing. This fixes the kext's permissions (basically what System Utilities does in Multibeast). If you're running Mac OS X Lion, this is all you need to do. If you're still running Snow Leopard, you also need to clear the kernel cache. Type in this: sudo rm -R Extensions.kextcache.
sometimes the system requires an administrative actions by the administrator, such as disk checkup, partition altering, drivers uninstalling, backups, etc.

at this delicate tasks you don't want other users to touch/create/remove/use files, hardware, CPU, and use resources. this is why you enter into single user mode.
What can you do in 'Single User' Mode?
Single User Mode Sql Server
since single user mode is for administrator and no GUI is available then every task you can do from terminal (command line) as root user you can do here, which is practically everything (on the current system) it wasn't meant to be used for regular work such as surfing the web (there is no network) or reading files etc. you can use all the unix commands available for OS X and all the command line utilities and applications available on that machine.
How to enter Single User Mode?
- Restart your computer
- Continuously press F8 until you see the Darwin boot prompt
- write '-s' without the quotation marks and press enter (for real mac do this instead)
- you will soon reach a prompt
- note the lines written to the console about fsck and mount
- write: /sbin/fsck -fy
- press enter and then the system should write:
** The volume XXX appears to be OK
or
***** FILE SYSTEM WAS MODIFIED *****
if it is the second option, then repeat the fsck command (6) until you get the first line saying the volume is OK - write: /sbin/mount - uw / this will mount your file system
- thats it you are in 'Single User'
