Laptops :: Using MacBookPro Boot / Open Firmware Password Protection?
Dec 24, 2008
I have MacBook Pro 2.4GHz Penryn 15". OS X Leopard, 6 months old.
In trying to add up to a wireless network at home (with a PC and a laptop Windows XP) I switched to "start from network" on System Preferences. On reboot, shows image of file with a ? or flashes a world clip. Usual command+S or C, Alt, attempt to reboot from CD fail. Before attempting anything else I don't want to lose my documents. When reboot with Alt, the padlock with space for password appears. I didn't set a password when I installed OS.

I have downloaded Open Firmware Password.dmg at the link provided in the article. Anytime I try to open it, a message comes up: "The following disk images couldn't be opened: Open Firmware Password.dmg, Reason: legacy image should be converted."

My MacBook Pro (Late 2011) which is fully up to date, no longer boots up. The last thing I did was set a firmware password via Lion Recovery mode. After setting the password, I restarted the MacBook Pro, logged in, unbound the Mac from AD and OD, gave it a different computer name and chanegd the IP settings to DHCP. I shutdown the MacBook, plugged in a Firewire cable and turned it back on whilst holding down "T" to boot into Target Disk Mode.
The screen turned on for a second then suddenly turned off and the light on the front of the MacBook slowly pulses as if its in sleep mode. I've restarted the MacBook several times, with and without holding down any buttons and now it will not boot up properly. When you turn the MacBook on, you can hear the CDROM Drive/HDD moving - like it usually does but with no feedback on the screen. After the normal sounds have stopped the light on the front of the MacBook pulses as if its in sleep mode.

Mac OS X (10.7.2)

I've just set up an Open Firmware Password for the first time. My understanding is that this would prevent booting the Mac from another volume (i.e. an OS X install DVD). After setting up the password and rebooting my machine, I decided to test things out by inserting my OS X install DVD and selecting it from the "Startup Disk" preference pane. Lo and behold, it rebooted from the DVD without asking for the password.

I tried to download the lastes version of open firmware, but it is incompatible with the version of my computer. Don't tell me to use a disk I got with my computer, that would be for a Macbook Pro, not a Macbook, which is what I have. Please tell me if you can find a link to a firmware password program for Mac OSX 10.6.8, or if you have another way of installing a firmware password.

I have a iMac G3. I can't make it boot from the CD to install the OS. Keep pressing the C key, but no luck. How can I edit it in open firmware to make it boot from the CD? Or, is there another option to install the OS from a different Mac? I have Mac OS X installed on a PC.

I have the Open Firmware Password enabled, which prevents my machine from booting into Safe Mode when I hold the shift key at startup (as expected). As a result, if I want to use Safe Mode I have to boot up from my install DVD, disable the password and then reboot. Very time consuming! I just read about a way to boot into Safe Mode:
(at [URL="http://support.apple.com/kb/ht1455"]Apple Support[/URL)]
by entering the following terminal command: sudo nvram boot-args="-x"
I'm a little hesitant to test it out in case I run into some sort of Open Firmware/Safe Mode conflict.

My open firmware password wont reset.
I tried the method of removing some ram and yes i did it correctly plenty of times and got nothing.
then i also opened the whole intire computer and disconnected the battery and also got nothing.
also right now the system has no O/S so i am not sure what to do from here. I cant use any boot commands or anything.

I just picked up an old eMac today that I'm trying to get it working. The problem is the open firmware password is set, and I have no idea what it is. If the open firmware password is set, it prevents you from doing anything without it including booting from a CD and zapping the PRAM. I changed the ram, removed the internal battery and hit the PMU reset button expecting this to clear the password, but it didn't work. Removing the internal battery did reset the system clock to 1/1/1904, but didn't change anything else.
Also aside from the practical question about resetting the password, I'm suddenly left wondering where the system stores the open firmware password. If it isn't stored on the hard drive, and it doesn't depend on the internal battery, then how is it saved? Just for clarification I have no idea who the original owner was or where it came from. So there is no chance of just finding the correct password.

So, I'm still having trouble with the MacBook I posted about here. It kernel panics even more frequently now, a month later, about once every 30 minutes. I'm running 10.5.8 now (no Snow Leopard for me!).
Anyway, the problem I'm posting about is that I can't boot into Open Firmware. It works fine just booting straight through to OS X (except about a third of the time I start up it kernel panics right after the Apple logo appears) but it won't boot into Open Firmware. I hold down Command-Option-O-F to no avail and it just won't go. (I'm trying to do reset-all to see if that helps any.)
I tried booting into Open Firmware successfully on my other Mac so it's nothing I'm doing, this MacBook obviously has some serious issues.
I'd rather not have to take this computer to the Apple Store again - every time I do they just reinstall the system/replace the hard drive and don't take me seriously when I say the problem is not with software. (Plus the warranty on this machine is up now and I'm trying to avoid paying hundreds of dollars!)
Anyone know what the issue could be? i really need a new computer hahaha...
Oh! I also tried booting into Open Firmware by holding down the power button continuously as suggested here... the on/off light blinked 3-4 times, the computer made a really long beep (like I was trying to do a firmware update), then started as normally. So I don't think that worked either lol.

I have a dual 1.8 PPC G5 power mac that I bought used about a year ago. It came with OS 10.5 preloaded but the only discs I have for it are the original system disks(10.3). I've got it hooked up to a HP 19 LCD via DVI. The other day I tried to boot into open firmware using the command-option-O-F start up command. Well, something happened cause OS X never came up, but nothing else did either. The screen just stayed blank, the fans starting ramping up and just got gradually louder and louder. I tried entering mac-boot via the keyboard thinking that maybe I was in OF even though I couldn't see anything on screen, but nothing changed.

I have a 500GB g-drive that I use with my macbook Pro(running Leopard O/S, current version). Because I just about maxed out the hard drive on the mac, most of my Aperture photo libraries reside on the g-drive, in a volume labeled "Aperture Photos." Something very weird happened a couple days ago that really spooked me. The G drive is configured in 4 volumes, and upon ejecting one of the volumes from the Finder window (by dragging it to the Trash which normally doubles as an Eject mechanism) my volume disappeared without the usual prompt that says something like: do you want to eject all So here I am, looking at my Finder screen, and 3 out of 4 of the G drive volumes remain listed in my Devices list, but the one with the photos on it is gone. With fear in my belly, I looked in the trash, and it looks like the contents of the entire volume ended up in there!!! So panic mode set it what do I do?!? How do I restore it? Whats weird is that the missing volume and its icon shows up on the desktop, but not in Finder, making it all but useless.

I was travelling and added a firmware password a few months back, I now want to disable this to install Ubuntu on a partition of my MacBook - but there are no directions how to in the utility.I looked at the Apple doc I originally used to set the password: [URL]/HT1352, and I cannot find a companion document for taking it off. So, if anyone knows how I go about doing this,

I need help setting a password protection that would be activated when there has not been use for 30 sec. My kids have gotten on when I was working on important files and now many are missing.

I have password protection enabled on my operating system so that I can lock the computer, and also so that a password has to be entered after the computer has been sleeping or has been closed. However, when starting the computer from being powered off, no password is required.
My question is: if the computer is in sleep mode or is closed, if someone powers it off and the turns it back on, will they be able to bypass the password protection?
I know I can set the computer to ask for a password before logging in after startup, but it seems that if the computer is in a password protected sleep, that the sleep image would make the computer remember that it was password protected, and would prompt for a password before logging into my account.

I use Time Machine to back up my data and am very satisfied but have one problem with it. Is there anyway to password protect the backed up data or even the entire external hard drive?
My user account is password protected but it appears as if anyone who has physical access to my external hard drive can access all of my information. If this is the case, how can I protect my data?

I have a time machine back up of my mac on an external hard drive. If this HD was stolen/lost would an avergae joe be able to access the data. i.e if it was plugged into another computer would all my files be accessible.
I use a password to login to my admin account and i'm the only user account.
Do i need to add some protection to my external? I realise that a clever mac user could get around any protection.

I use PowerPoint for work, and I sometimes receive password-protected files that my iMac (OS X, 10.5.8, PowerPoint for mac: 2008) cannot open.
If I want to open and work on such files, do I have any options besides running Windows?
If I run Windows, should I use XP or Vista? I do not have any use for Windows except getting to those password-protected PowerPoint files.

I was looking to buy an iomega hard drive because of its portability and firewire. Here's one I found on amazon at a discount : http://www.amazon.co.uk/Iomega-500GB...9149335&sr=8-1
Everything seems fine but for something so portable and easily lost (or stolen/misplaced) as well as carrying my entire mac backup (docs, photos, videos, etc.), I think password protection or some other security feature is essential nowadays.
Does anyone know whether the imoga hard drives have password protection or not? If not, are there any other hard drives with both firewire as well as good security?

I am running version 10.4.11 of OS X and would like to find software that will allow for password protection for a folder(s) on an external hard drive used with my MAC. I want others to be able to access most of the files on this drive however. Setting multiple users with passwords will not accomplish what I am looking to do.

Gah, internet is messing up, logged me out I have to rewrite my whole long message....when transferring between my new MBP and ibook G4 on 1st startup.... it asked me to connect by firewire. Idon't have a firewire that has 1 side the new firewire connector and the other side old (I didn't even know that the shape of the firewire had changed). I tried to do it wirelessly and it said it was going to take 106 hours so I stopped it to use my computer.
Now I am trying to transfer again. I don't have a firewire cable that will work. I have an ethernet, but when I try to connect to my computer server (through ethernet or wirelessly) it says that I don't have sufficient privileges. My password (which I am sure is correct) DOES NOT WORK and I don't know why. I tried to disable all security so I can get in with no password, but nothing I do is working.
Any ideas?How can I transfer my files? How can I get back to that transfer wirelessly screen that occurred at start up? Migration Assistant only gives me a firewire option. Is there a firewire that will connect between old and new firewire models???
How do I set up a network connection with no password protection? (Or why isn't my password working?)

A while ago, I set a firmware password on my Unibody MBP's HD and now I'd like to remove it. (I haven't forgotten it or anything, I'd just like to remove it)
I did it using the Leopard install DVD (firmware password utility) but when I open that utility again, there's no option to 'turn it off' .

Can someone point me to a link or provide some clarity on what NOT having a firmware password means in terms of security and, as a home user, do i need to put on on?
All my personal files are in 'Knox' dmgs - i work out of the dmgs - works perfectly. But i dont know for sure where else other background/usage info is stored on the computer.
I remember i while back reading that without firmware password if someone got your mbp (physical possession) then they could reset the password and get into your user account (with mac osx cd) ... can someone confirm (im reasonably sure this is correct).
I had the password on my last mbp but havent got around to putting it on this new one. I was about to today but its been awhile and maybe there is new information or perspective for me to consider.
How many of you have a password installed?
What are the pro's & con's?

At my company, we have a MacBookPro8,2, running Lion v10.7.3.. We are trying to set the firmware password on it and don't seem to be able to do so. Booting from the Recovery Partition, we choose the Firmware Password Utility, turn it on and set the password. Upon rebooting and holding down the Alt/Option key on the keyboard, we are not presented with the lock icon, nor are we asked to enter the password we just set. Booting back into the Recovery partition and opening the Firmware Password Utility, we must enable it again and set the password again.
