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.

Intel iMac, Open Firmware Password Protection and booting from CD

I have an Intel iMac I'm setting up for use in a public library. I want to prevent single user login with the Open Firmware Password Protection utility, but if I do, how do I boot from the OS disc, zap PRAM, etc? The OFPP page has instructions on removing the OF password, but it does not work on Intel Mac's. Also, is there an alternative way to prevent single user login?

No, you were right, I just misunderstood. Technically it's called single-user mode. But, you were right.
Anyway,
Since it seems that there might not be an answer directly related to your topic you could maybe give this a try.
In Simple Finder the user can not restart or shutdown. They can only sleep and log out.
The other problem, however, is if they log out then there are those Sleep, Restart, and Shut Down buttons on the login screen. Luckily, though they can be turned off.
So as of now, if some is logged in in a Simple Finder account they can not restart or shut down the computer in order to get into single-user mode. They can also not get into the Administer account since it is password protected.
The only problem I can see with this is that a person could do a hard shut down, hold the power button down until it turns off, and then boot up and enter single-user mode.
If you want to go ahead and do this, in order to get the computer up and running in the mean time, just post back and I'll be glad to help you set up a Simple Finder account.

Open Firmware password

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

Disable Firmware Password Protection

I have a G4 Digital Audio. Since i installed a 1,7GHz procesor upgrade (Sonnet Encore) and had to apply a patch to the firmware it seems that open firmware password protection is enabled. Now i'm in trouble as i can't start up from a selected disk (i didn't consider it's on a > 128 GByte partition) and as i don't know the password (i haven't enabled it) i can't use the option key, so i can't startup the computer from any disk. Reading this: http://docs.info.apple.com/article.html?artnum=106482 i realized about the password protection and that there may be a way to bypass it having fisical access to the computer. Any hint what i can try to start up my computer again?

Hi, Olaf -
There is a way to do that, but to help others avoid having their Mac's security breached (particularly those with laptop machines) it is not publicized. You should contact Apple Support by phone, or take your machine to an AASP.

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

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

Has Anything Replaced Open Firmware Password?

Has Anything Replaced Open Firmware Password?

It's a loaded question you're using in someways. If what you mean is, "Is there an Open Firmware equivalent for Intel-based Macs?" then the answer is yes. See the following Apple KB article for full details: http://support.apple.com/kb/ht1352
======
YES, that's what I meant. I have a late 2010 MacBook Pro w/ Core-i7 CPU
I read the article and I find confusing info. In one paragraph it says Intel Macs use EFI and in the following paragraph It says "Any Intel Based Mac" can use Open Firmware*
"All Intel-based Macintosh computers support firmware password protection.
The following Apple computers can use the Open Firmware Password application:
▪ iMac (Slot Loading) and later models of G3 iMac
▪ iMac (Flat Panel) and later models of G4 iMac
▪ iMac G5 and later models of G5 iMac
▪ iBook - all models, both G3- and G4-based
▪ eMac - all models
▪ PowerBook (FireWire)
▪ PowerBook G4 and later models of G4 PowerBook
▪ Power Mac G4 (AGP Graphics) and later models of G4 Power Mac
▪ Power Mac G4 Cube - all models
▪ Power Mac G5 and later models of G5 Power Mac
▪ Any Intel-based Mac*
▪ MacBook Air: see MacBook Air: Recovering a lost EFI firmware password"
So do I use Open Firmware or EFI?
"Apple make up your mind please..."

Can't Bypass firmware password protection. Don't remember it

Hello, so i've recently installed windows 7 for bootcamp. But when i press option, it takes me to a lock symbol with a password protection. I dont remember my firmware password, and i've looked everywhere for a solution. Resetting ram doesnt work, downloading the open firmware password utility doesnt work, and pressing cmd + r doesnt work either. Im running Lion v 10.7.4. Help! I certainly do not want to reboot everytime to switch partitions!

Removing open firmware password -- too easy?

I've had an open firmware password set on my computer for the last two years to provide some protection for client data stored on it. But last night I had to do some troubleshooting using startup commands, so I wanted to temporarily remove the password. I found instructions for removing it by booting into open firmware (command-option-o-f), but this startup sequence did nothing.
Eventually I booted from the Snow Leopard system CD and opened the Open Firmware Password utility. This utility had a simple checkbox that let me remove the password, without entering the current password. Is it really that easy to remove the open firmware password? If so, I don't think it's worth the occasional inconvenience of keeping it on there.

There's nothing you can do to prevent a determined hacker with physical access to your machine from getting access to everything on your hard drive. What you should do, however, is make sure that any information that is sensitive is encrypted. You could use an encrypted disk image made with Disk Utility for this purpose... many do. Also, note that your keychain is encrypted and thus passwords and other things stored there are safe... but only as long as you do not auto-login with an auto-unlocking keychain or leave yourself logged in with the keychain unlocked. Although your account password could be reset by someone with the right knowledge who wanted in, this does NOT affect the keychain password.

Turn off open firmware password without OS CD, or transfer account?

I've got the open firmware password turned on on the iBook I use for work. The laptop's CD drive recently stopped working, and I don't have access to an external CD drive. I need to bring the laptop in for repair, but want to move my account onto another iBook while this one is in the shop. Because the open firmware password is on, I can't use the migration application. Because the CD drive doesn't work, I can't use the OS CD to turn off the password.
I do have access to an external hard drive. It would be a pain to have to reset everything on a new computer, so I'd greatly prefer to be able to transfer my account instead of just my files. Is there any way to turn off the firmware password or transfer my account using the external drive?
Many thanks!

Change your RAM configuration (add or remove a RAM module). Then reset the PRAM by holding down command, option, P, and R. Keep them down until you hear the third startup bong. That will defeat the firmware password protection.
But if I read your original post correctly, you shouldn't need to bypass the OF password. Just boot up your iBook, plug the external drive into your iBook, and copy your files over. You can even use a program like SuperDuper to make an exact copy of your internal drive to your external one.

Open Firmware Password for Intel MAcs

I had used this application and password protection for my G4's. Does it work for Intel Macs?
20" iMac Core Duo 2/ 14 iBook [1 ghz] Mac OS X (10.4.7)

Yes,this support article says that Intel does support open firmware password and gives the steps to set.

Firmware Password Protection for Intel Macs?

PPC macs can use the Open Firmware Password utility to protect the computer from someone booting of another drive to access your data http://docs.info.apple.com/article.html?artnum=106482
How can this same protection be accomplished with Intel-Macs? Intel Macs use a different fireware/boot process, so OFP above doesn't work. according to the apple article above, it can be done - but it doesn't explain how:
"Intel-based Macintosh computers can be protected by firmware passwords as well. The firmware in an Intel-based computer uses Extended Firmware Interface (EFI) technology"

Install DVD1 apparently has a Universal Binary called 'Open Firmware Password' on it that works just the way it did on PPC Mac's (not tried it personally)
According to this post it was fixed in 10.4.6

Open Firmware Password option in Lion?

When I upgraded to Lion on my mid-2009 MacBook Pro yesterday, I discovered that the Open Firmware app from Snow Leopard no longer works. Is there an Open Firmware Password app for Lion? Normally, I'd pull it from the disk after install, but obviously there's no disk for Lion. Thanks for you help!

It might be easy to circumvent, but I didn't say you had to use only this password...
It is an additional protection...
And if your Mac gets stolen by someone who is less an expert, he won't be able to (easily) reinstall anything on your Mac...

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!

Forgotten Firmware password protection And no OS on hard drive

I really need to know how to get it off. My hardware has been wipped and there is absolutly nothing on it. And i need to take Firmware password protection off in order to install anything onto it.
