Im trying to update firmware on my SSD drive. However, when I hold down the option key it requires a password to select a disk. This does not allow for the .iso imagine, on the DVD, to be seen so I can update my drive. How do I remove this requirment in 10.8.2?
MacBook Pro, OS X Mountain Lion (10.8.2)
if i dont remember my Firmware Password, so how can i do this ?

Another method that I used is: assuming you can log into OS X and have sudo abilities then open the terminal and type "sudo nvram -p" where the password will be your login password. It will display the security password string. Then type "sudo nvram -d security-password". Reboot. Should be gone. Then you can reboot and hold down command-R to boot into the recovery console and set a new password or just leave it alone. At any rate, I've had to do this a few times myself as I forget what I set the firmware password to.
Hey, try this, it might help you remove your forgotten firmware password. Try removing 1 stick of ram from your computer, leave the other one alone, then turn on your computer, then write away press and hold the command, option, p, and r keys. After you here the startup chime beep 4 times, you can release the keys, then turn off your computer and put the stick of ram you removed, you should be good to go. Let me know if this helps you.
As already stated, if you don't know the firmware password, you will need to contact Apple. The RAM trick mentioned by boisebimmer does not work on recent hardware. The post marked solved by mtnbk7 should not work, and if it did at some point, that was a serious security flaw that I would hope has been fixed.
Sorry if it seems obvious, but which is the security password string? (I get a bunch of lines with efi in them) And after do I have to write "security-password" or copy something that came up in the previous command? Writing security password just gives the normal main line in terminal.
Thank you
If you do not know the password, the only way to remove it is to take it to Apple and have them do it for you, for security reasons.
To remove the firmware password you need to remove the ram and swap it with diffrent ram. Then do a PRAM reset.
This will remove the firmware password.
Perfect. Thanks ever so much.
