Seems you have this set then...


Firmware password protection in Mac OS X ...


http://support.apple.com/kb/HT1352


It would block usage of all the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option, and Shift, as well as booting from anything but the Hard Drive.


Force Removing Password Protection


1) Add or remove DIMMs to change the total amount of RAM in the computer.


2) Then, the PRAM must be reset 3 times. (Command + Option + P + R).

hi BD, i followed the directions below and successfully entered a new password. my computer then re-started after i typed "reset-all" but once again at the login command the new password is not working...when i was entering that info i chose,"setenv security-mode none" as well. i feel like im getting close but still no success getting in!


what should i do from here?



Procedure

Enabling Password Protection

1) Boot into the Open Firmware. (Command + Option + O + F)

2) At the command prompt, type "password" (without the quotes, of course). You will be prompted to enter in the password you wish to use. Type your password, press the return key, retype your password again, and press return to verify that that the first password you typed is indeed the password you want. (Note: the password is stored in the "security-password" variable, but the contents of this variable is never shown via the "printenv" command.)

3) Type "setenv security-mode full" OR "setenv security-mode command" OR "setenv security-mode none", depending on which level of security you wish.

4) Then type "reset-all" to restart the computer.

Ah, OK, so it IS a login PW & NOT Firmware PW, great...


Reset OS X Password Without an OS X CD...

Admin Hack...

Starts up like the first time you buy a new Mac, but after filling in all that info again, you should have access to the computer and the other Users & files will still be there... give the new User a different name than an existing one.


PS. Something is wrong with the c key, the Optical drive, or the Install Disc.
