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

Open Firmware Password Doesn't Work

I've been using O.F.P. v 1.05 on both my computers for over a year. All has been well until recently. Now when I reboot holding down the option key I either get the O.F.P. screen without the password line so I can choose any bootable disk or I get the password line, but when I enter the password nothing happens and I have to reboot normally.
Both computers running 10.4.3 with all latest updates.
What's going on?

Well, I just searched the Apple Support Knowledge Base and found this text here at http://docs.info.apple.com/article.html?artnum=106482. In the section "How to enable the Open Firmware Password" it says right in the first paragraph:
1. For Mac OS X 10.1 to 10.3.9, Download and Install the Open Firmware Password application, which you can get here. For Mac OS X 10.4 or later, you must use the updated version that can be copied from the software installation disc (located at /Applications/Utilities/ on the disc).
The link for version prior to 10.4.x leads to OFP 1.0.2, so 1.0.5 might already be the updated version that ships with Tiger. I can not check right now because I am not at home where my copy of Tiger is; maybe others can check it in the meantime.
If you not already have done so, maybe you could try to update 10.4.x to the latest version (which is 10.4.3) and get all other available patches as well, just to make sure.
Regards
Jim
AiPB 15 1,25 GHz;; iMac 17 1 GHz (flat panel) Mac OS X (10.4.3)
UPDATE: And I doublechecked that I am indeed running version 1.1 (1) of OFP on my installation. I am not aware of having it updated manually, so it must either have been this all along since I installed Tiger or been updated in the procress.

I cannot access my old email address anymore, however I have used it for my apple ID and now I want to delete it because the account has never been verified in the first place so my password for it doesn't work. So when I want to download apps I have to sign in with apple id but I can't so I made a new one, However I can't seem to be able to delete the old one. What do I do?

You can't merge Apple IDs. You also can't cancel (delete) and existing ID, you can only choose to stop using it.
If your old ID was compromised and you can no longer access it, you'll have to contact Apple for assistance. Go to https://expresslane.apple.com ; click 'See all products and services' at the bottom of the page. In the next page click 'More Products and Services, then 'Apple ID'. In the next page select 'Other Apple ID Topics' then then 'Apple ID account Security’.

You can't open Detour preferences because it doesn't work on an Intel-based

i downloaded a program called 'Detour'
it clearly should not have been installed on this computer.
it is not in my applications folder, however it is a pane in my preference program. the error that comes up is this:
"You can’t open Detour preferences because it doesn’t work on an Intel-based Mac"
how do i find this troublesome program and delete it for good?
much appreciate the help
Foti

Welcome to Apple Discussions.
It may just be the preference pane. Right click on the Pref Pane in System Preferences and "Remove".
Is it interfering anywhere else?
If the app is not in your Applications folder and it exists, look in the Utilities folder.
Alternatively, try AppCleaner

Update 10.5.7 "You cannot open Sharing preferences because it doesn't work"

Please help,
After installing the 10.5.7 update, I can not access my sharing settings in System Preferences. It says "You cannot open Sharing preferences because it doesn't work on an Intel-based Mac."
Any Ideas?

Install the combo updater. Somehow, the Intel slice of the binary got stripped out on your machine (and/or the binary patching failed in a way that corrupted the relevant part of the Mach-O header). Don't ask me how that would happen, but apparently, it did.

Thanks for replying, I'm a real techno-cretin. What do you mean by not using the backup? I'm busy trying to restore my new phone and it's doing a 6 hour download with updates. Can I restore the data from my old phone backup onto the new iPhone 4S when the download is done?

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.

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 -

Open Firmware Password..oops

Today I decided to see if the startup disc on my external HD was working properly. I went to System Preferences and clicked over to the Maxtor as my prefered choice. I did not click the lock at the bottom. I then clicked Restart, everything on the desktop dismounted and the screen went dark and then came back up with the gray screen with the spinning wheel....and stayed there.
I noticed that there was a circle with a line through it and then I noticed that my iPod was still connected, it was dismounted and charging.
I shut off the power, to the iMac, disconnected the iPod and turned the power back on, and the gray screen with flashing folder with a question mark appeared.
I went to the MacBook and did a search in the discussions and the only thing I could find out was that I needed to boot from the install discs, hence the oops.
I have Undercover installed, and part of their setup is to enable the Open Firmware Password.
How can I get my iMac up and running if I can't use the install discs or target disc mode?
Any suggestions would be greatly appreciated.

ddougYo, I have the Orbicule software on 5 MAcs (it nearly got one that was stolen back for me too) and also had its predecessor, Lapcop which also used the Open Firmware Password utility.
You are not going to be able to boot up until you can get through the Firmware Password Utility and there are only two ways: the password itself, or the method that Baltwo has suggested. If the password is not working then you have possibly not entered it correctly.
If, for some strange (unidentified) reason that is not the case, then Baltwo's solution is all you have left. Have a look at the manual: getting the iMac's RAM out should not be hard. Do you have one or two modules? If one, try putting it in the other slot.
