OS X :: Open Firmware Password - Booting From Another Volume

Nov 5, 2010

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.

MacBook :: Install An Open Firmware Password On 10.6.8?

May 3, 2012

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.

Info:
MacBook, Mac OS X (10.6.8)

OS X :: Safe Mode And Open Firmware Password Enabled

Nov 11, 2010

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.

Software :: EMac - How To Reset Open Firmware Password

Sep 9, 2009

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.

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.

MacBook Pro :: EFI Firmware Update 2.5 & Booting OS 10.6.x?

Apr 23, 2012

Are there any known compatibiity issues with booting from an OS 10.6.x drive after installing EFI Firmware Update 2.5?I am running Lion (10.7.3) on my MacBook Pro (13-inch, Mid-2010) but have held off installing the firmware update because being able to boot from a 10.6.x backup drive is more important right now than internet-based Lion recovery. If there's no issue booting 10.6.x (and running apps), then I will go ahead and install the firmware update, otherwise I'll wait awhile longer.

Info:
MacBook Pro (13-inch Mid 2010), Mac OS X (10.7.3)

MacBook Pro :: Most Recent Firmware Update Prevents Computer From Booting?

Feb 24, 2010

I recently attempted to install the most recent firmware and security updates for mac os x 10.5.8 on my macbook pro 17 inch (purchased about 14 months ago). Computer asked me to reboot, i did, it then gave me instructions for firmware updates.

The screen went dark, and it did its thing, and I returned 10 minutes later. The computer had not rebooted.I pressed the startup key and it gave a long beep. Screen remained dark. Some minutes later it ran the boot cycle, but booted into windows (i have dual boot set up). I can only get into windows now.

OS X :: Move Applications Folder On Non Booting Volume?

Mar 28, 2010

I was wondering how I can move the Applications folder of my boot volume to another drive? The 'other' drive is an ExpressCard SSD as I want to take advantage of its speed. I used to run SL from it but I keep having this stupid problem. So the next best thing is to run frequently used files from the SSD in hope that it works fine. Btw, unfortunately I cannot simply create a symlink to my boot volume as I cannot remove the Applications folder from it.

OS X :: How Important Is A Firmware Password

Mar 1, 2010

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?

OS X V10.7 Lion :: Cannot Set Firmware Password

May 4, 2012

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.

MacBook Air :: How To Enable Firmware Password On Laptop

Nov 2, 2010

This is my first mac. Very happy so far (7 seconds boot time is fast!). Anyways, I am used to enable firmware password on my laptops so if it get stolen I know it cant be used. On PC you can usually press a button, get into bios and set it there. After googling around I found out I need something called Open Firmware Password or something from Apple. It says I should install it from the disc, but I didn't get any disc. So where do I get it? Do I find it on the recovery USB? Or can I download it? (I don't have the recovery USB with me, that's why I ask).

Software :: Forgot Firmware Password On MacBook Pro?

Apr 3, 2006

Some weeks ago, i set the firmware password on m y MacBook Pro. I set it to something complicated but memorable ... But now, of course, I can't remember it!

I've been googleing the subject, but there seems to be nothing about resetting the MB Pros Extensible Firmware.

The problem is even bigger, because I wanted to repair permissions yesterday and thus booted from the indtall dvd. I had forgotten about the EF passeord, so I set the startup disk to be the DVD drive, and now I cant get the machine to boot from its harddrive, so I have no access to my data.

I have tried to remove the 1gig ram block, that should reset the password in the old Open Firmware macs but no dice!

Im desperate because later today Im being interviewed about my mac and tech in general, and i really need my notes and stuff on the mac, plus it would be so embarrassing that iv'e set a password i cant remember - might as well cancel the interview :-(

Is there anyway to make the MBPro boot from the harddrive again, or is there a reset button on the motherboard?

MacBook Pro :: Won't Boot After Setting Firmware Password

May 21, 2012

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.

OS X :: Apple Hardware Test Versus Firmware Password?

Jan 5, 2009

is it possible to use the Apple Hardware Test if I have a firmware password?

I know firmware password stops you from using the "c" or "d" during the boot, and I haven't seen any alternate way to start the Hardware Test (I managed to use the Disk Utility by booting to the DVD, but there wasn't an option for the hardware test that I found there).
