Firmware password protection in Mac OS X ...

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.

How to reset a firmware password?

do you know how to reset the firmware password on a workstation ultra 30?
each command on the ok prompt ask me for a firmware password. i tried (of course unsuccessfully) several.

@rukbat,
You are partially correct. It depends if the security-mode is set to "command" or "full" (and if auto-boot?=true). If it is set to command, he can put in the other systems disk (in the same slot) and enter "b" to boot, then enter the eeprom command as root after he logs in. However, he cannot boot to cdrom because the boot-device is directed to the hard drive and cannot be changed without the eeprom password. I have used this technique to set security-mode=none on several E250s in years past.
If it is set to "full", his only option is to enter the password and log in to get an OK prompt, which leaves him where he currently is.
You dont have to get your prom from SUN. The SUN part number for an Ultra30 prom is: 525-1669, which you get several hits on if you search. IIRC, anysystems.com doesn't list the part but they can probably help you out.

Open Firmware Password Protection?

Anyone had any luck setting this up? I don't see it on the DVD... I am hesitant to use the one from my Tiger CDs... anyone know how to setup Open Firmware Password Protection on Leopard?

Thanks for detailing your solution Mac Campbell.
Unfortunately I can't locate the Firmware Password Protection application in the directory you listed nor any other folder for that matter. I'm not confident its been installed on my system (clean install of Leopard btw). Could you please confirm its exact location for this Terminal newbie.
Many thanks in advance.

Any one know how to reset the open firmware password?

iBook G4. 1.33ghz. 1GB RAM.30 or 40GB HDD. Running 10.5.8
I got this from a friend, who got it from a friend. And its acting funny. It works. But a lot of options are missing from the System Preferences pane. And another friend said to reset the NVRAM and all the setting in the open firmware. Only no one seems to know the open firmware password. And I can't seem to find how you'd reset all the setting in the open firmware. I'm working on locating the installation disks for this iBook. But will that even help me with this resetting open firmware business?

I did a google search and here is one link that might have some helpful information -

How can I reset the open firmware password?

I wanted to installed Mac OS X Lion from scratch on my newly purchased MBP 15,4"
I put the installESD.dmg on a USB pendrive, then I boot on it. I used Disk utility to erase en encrypte my drive, and at the same time I set the Open firmware password.
I launched the installation process, after a while the computer reboot but I got an error:
there was a problem installing mac os x try reinstalling
I google this error and found many people who solved this issue by erasing the PRAM using the shortcut: cmd + opt + P + R. I'm asked to enter the password which I did but it's still keeping asking for the password so I guess its wrong which is weird cause I typed it in few minutes ago, so I might have done twice a typing error or I don't know.
So my question is how can I reset this password to be able to install my OS? (I cannot access to any OS cause the installation process failed).
Thnak you for your help

Yes I did use the disk utility to restore the dmg on my USB drive. The USB drive is perfectly fine, I can boot on it without any problem, well before setting this open firmware password I could do it.
Now the situation is:
No system installed,
Lock with a password
I have the disk to install SL but I cannot boot on the DVD because it is asking me for this password.

Reset or change Open Firmware Password

I recently set up a few computers with an Open Firmware Password.
I've read the following information on the Apple Support Site:
+Important: If you reset the PRAM or Open Firmware, you need to reselect your startup device prior to resetting the Open Firmware Password.+
+Warning: The Open Firmware Password can be reset and changed by any one of the following:+
+1. By any administrator user, as designated in the Accounts preferences (or in Server Admin).+
+2. Via physical access to the inside of the computer.+
+3. When the computer is started up in Mac OS 9.+
Here it says that an administrator can reset or change the Open Firmware Password, but it does not say how to do it. Can someone explain how I can reset or change a password.

Insert your "Mac OS X Install Disc" for Leopard, it contains a program to set and reset the firmware password. Because the corresponding folder on the disc is hidden you have to change directory by choosing "Go to folder" from the "Go to" Finder menu and typing in the dialog box:
/Volumes/Mac OS X Install Disc 1/Applications/Utilities
Now Finder will display the contents of that folder. Copy "Firmware-Password" to your Applications folder. You have to be an administrator in order to change the password with that program. Let me know if that worked for you.

Lost open firmware password - any way to reset?

Hi
I lent my PB to someone and I don't know exactly what happened, but now the PB can't start up. I get the flashing Finder icon and question mark, so I got out my install discs and tried to repair permissions/reinstall. But I set an open firmware password which I have now forgotten, so I can't boot up from the disc. Is there any way that I can reset the password, or somehow reinstall?
I did check the airport card, it seems to be seated properly.
I'm running 10.3.9 on the 1.33 GHz PB.
Any help will be hugely appreceiated. Thank you.

Thanks Gossamer, but I can't reset the PRAM because I've lost my open firmware password.
I'm basically stuck with a PB that won't start up until I remember my open firmware password (which is unlikely) or I am able to reset the password somehow.
I didn't mention in my first post - when the PB goes into open firmware mode, the screen displays:
"Invalid memory access at SRR0: ff84a4d0 SRR1: 0000b030"
Does this indicate a problem with the memory?

How can I reset my firmware password?

Hi when I bought my macbook pro second hand, I didn't realize there was a firmware password for the computer making it impossible to enter the boot options menu. I have tried the password that came with the computer and my user password and neither worked, so how can I reset the password? Is there a general default password? Any way I could do it without going to the apple store as the nearest one is three hours away and I don't have transportation to get there.

Welcome to Apple Support Communities
You can only reset the firmware password if you know it. Also, you need to start from OS X Recovery or the OS X disc in order to reset it, so it's not possible to do anything else. The only thing you can do is to take your computer to an Apple Store or reseller, because there's no way to reset your firmware password that we already know

Open Firmware Password; not on Snowy Upgrade DVD; how do I get hold of it?

hey;
my MBP15 came with 10.5 & i got the snowy upgrade dvd from apple; there's no Open Firmware Password utility on the upgrade DVD (i even searched using pacifist) and it cannot be downloaded from apple's downloads. this seems a serious omission since i protect my mac (somewhat) with it.
does anyone know how i can get it, since i think it's pretty product specific; if it's actually different from the version on the original 10.5 disk that shipped with the machine or would some kind soul with the same machine (MacBookPro5,1 MBP51.007E.B05) have to share it with me?

actually, don't trust me; i'm wrong.
thank you so much, roam! you do indeed have to boot from the dvd!
what had me fooled is that pacifist didn't find it, and it used to be a discrete file which you could simply drag from the utilities folder of the install disk on to your mac.
i have now enabled the firmware password!
thanks again!

I can't seem to reset this password. I've tried taking the battery out and hitting the reset button.
Anyone have any ideas?

Protect macbook with Open Firmware password

Hi. I'd like to protect my MacBook air by enable an Open Firmware password.
How can I do it ?

Open Firmware was available in PowerPC-based Macs, so your MacBook Air hasn't got it. Instead, it's a EFI firmware password, that will ask you for a password every time you want to start in a mode different than the normal one (without holding any key while your Mac is starting up).
To enable it, hold Command and R keys while your Mac is starting to start up into OS X Recovery. Then, go to Utilities menu (on the menu bar) > Firmware Password Utility, and enable it.
Don't forget the password. Only Apple knows how to reset it, so you will have problems

TS3554 open firmware password

hey
how can i reset the open firmware password? i'm using a 13" macbook pro 2011 intel core i5 running on OS X lion 10.7.5
ps> i have already tried to remove or add ram stick and restart pressing alt+cmd+p+r nothing

Welcome to the Apple Support Communities
Open Firmware is only on PowerPC-based Macs, so you want to reset the EFI firmware password as you have a Intel-based Mac.
To reset your EFI firmware password, hold Command and R keys while your Mac is starting to start in Recovery HD. Then, go to the Utilities menu, open Firmware Password Utility and disable the EFI firmware password.
If you don't remember the EFI password, take your computer to an Apple Store

Open Firmware password works or doesn't work on MBP?

I'm confused...
This article describes how to set up Open Firmware Password on Macs, including, Intel-based Macs and even states what OFP disables on Intel-based Macs when enabled:
http://docs.info.apple.com/article.html?artnum=106482
just to finish the article at the bottom with the following sentence:
"Note that Intel-based Macintosh computers do not use Open Firmware. Thesesteps do not apply to Intel-based machines."
So, what is what? OFP works or not on MBP? If yes then what works and what doesn't?
I've read one post here stating that it didn't stop booting from CD at all.
An expert advice will be appreciated.

I'm another confused MBP user.
I have a 15" MacBook Pro (MBP) and want to protect the Intel based machine using Apple's Open Firmware Application.
Since the MBP doesn't have an open firmware layer, how do you apply a firmware password? Apple's site is of no help and has conflicting information.
I tried the OF Application (V 1.1) from the Tiger install DVD and receive a message about my firmware being too old to use with the application. The MBP SMC version is 1.2f10 and the Boot ROM is version MBP11.0055.B03. Both are current.
Has anyone been successful???
thanks

Resetting a firmware password when never put a firmware password on Macboo Pro OSX Lion

I have never put a firmware password on my Macbook Pro OSX Lion (2012). But now when I am trying to reset it, its asking for a password how can I reset this or remove it.

Hi macbookprowilliam, I have the SAME problem, that grey lock just appeared trolling me. I dunno the password and I wan't to sell this macbook! I need the password. Maybe it's a new malware! I don't even know how to set a firmware password and I am the only user on this computer too! I have a thread about that too: https://discussions.apple.com/thread/3926399?start=0&tstart=0
So, did you fix it or got around it? Please reply! I am desperate.
Thank you
