No I just ordered one online, its not the same disc.

OK so I got in single user mode
type in sh /etc/rc I can't even see # on the laptop keyboard.  I get /etc/rc: line 28: $1: unbound variable.

So I type in sh and I get sh-2.05b# as the prompt then type /etc/rc and I get access denied.

Any ideas.

Boot the computer from the OS X install disc it came with and reset the password using the tools in the installation menus. Insert the disc, reboot the computer and hold C to boot from the disc. Select "English" language, and then Reset Password from the Tools or Utilities menu.

Sorry for the delayed response.

I have tried all and nothing works, I just purchased a OS X 10.3 disc and try boot up off thr CD and I get a big No sign (Circle with diagonal line).

Any ideas ?

IS the 10.3 Install CD a generic Install CD or was it designed for a specific Mac??

Usually inserting the CD .. then restarting the Mac with the C key held down should force it to use the CD .
However you may want to try booting with the Option (alt) key held down and see will it recognise the  Installation CD

I am wondering why you were unable to get to Single User mode .. do you have a standard USB wired keyboard connected to your Mac?
You need to use an install disc of the same version as the client software 10.3 restore disc wont work with a 10.4 workstation

If you are using a more recent version of os x 10.4 or 10.5 use these steps to change the change the password (from

   1. Boot into single user mode (press Command-S at power on)
   2. Type fsck -fy
   3. Type mount -uw /
   4. Type launchctl load /System/Library/LaunchDaemons/
   5. Type dscl . -passwd /Users/username password, replacing username with the targeted user and password with the desired password.
   6. Reboot
