I am running OS 10.8 and am trying to use the Recovery HD to repair my drive.  But when I try booting up using Command-R, or Command-option-R, or even just option, it reboots to a lock symbol asking for a password.  My admin password does not get past it.  I have full permission on the computer otherwise, but am not sure how to get past that screen.  I even tried setting up the recovery HD on a thumbdrive and get the same results on startup.  Any ideas?

MacBook Air, Mac OS X (10.7.3)

    Have you set password for your firmware ?

    That's what it is.  I just need to figure out how to reset it without the snow leopard CD.  It is packed deep in my garage.   Do you know how i could do it.  I was trying to navigate the apple support website but didn't readily see it.

    It depends on a computer or OS versions

    you may try:

    Add or remove a stick of RAM (change the amount of RAM - if you have one stick in, add one and if you have two in remove one).

    Power on the Mac and immediately press and hold command-option-P-R.

    The system will restart with the ‘bong noise’, allow it to do this 3 times. On the third ‘bong’ you can let go of the keys.

    The machine will now boot with a cleared password and reset PRAM/NVRAM.

    You can shut down the machine and replace the original RAM configuration.


    For later computers if you do not know the password the only option might be to shedule a meeting with Apple Genius....

    there is another way, which is far too complicated http://jerseycityrepair.com/remove-firmware-password-macbook-air/


    I am not sure that Snow Leopard disk will solve your problem, as the reset password utility may require an original password to change it.
