EFi/Firmware Password and Recovery Partition

Before I get my Macbook Air, I want to know, does having an efi password set prevent you from booting with cmd+r without the password.
I already know that Cmd+s, Cmd+opt, cmd+opt+p+r, do not work.
It would be great if someone would just test it on their Macbook Air running Osx Lion with a firmware password set, and tell me if the Unlock dialog comes up.
Thanks!

I'm pretty tired but when I had Firmware pw set, it boots instantly into your login dialogue and then proceeds to load (or not load) the OS. So unless I'm being re.tarded, as soon as you enter in the firmware password, you're effectively starting from where you'd be if you didn't have the password set.
To your question, I'm 95% sure that yes, you would be prevented from getting around the firmware password. I don't think you could...? I'd test it for you but my recovery partition has melted into the lba - apparently....

Removing EFI Firmware Password

When I bought my MacBook Air in February 2011, it came with OSX 10.6.6. Since then I have set the firmware password, and then upgraded to 10.7 and now 10.8. Currently at 10.8.2.
I now have to do something that requires me to boot in safe mode. To be able to safe boot I have to unset the firmware password (fortunately, I know the password).
But how do I go about removing the firmware password? Do I use the USB key with 10.6.6 software on it? Or do I use software from the Recovery partition on the HD?
Do I have other options?
Thanks for your comments.

You can use the one you want, but as you are running Mountain Lion, you can use Recovery HD.
1. Press Command and R keys while your Mac is starting to start into OS X Recovery.
2. When it has started, go to Utilities menu and select the option to set up the firmware password.
3. Turn it off and restart your computer

Boot Process with active EFI Firmware Password

I have a MacMini with Linux installed (for an embedded application) on the internal hard drive, and Mac OS X 10.5.6 available on an external Firewire / USB drive. The machine is a 1.83 MHz 2008 production unit with EFI version MM21.009A.B00 firmware installed (no later update is reported as available via the OS X Software Updater).
The system normally boots from the internal (Linux) disk without user interaction when first powered up.
In order to restrict users from starting the system from alternate devices, we activated an EFI firmware password. After doing so with the Open Firmware Password application on the OS X installer DVD (booted with option key and selecting the DVD icon, or with the C-key held), the system no longer automatically boots either of the two available hard disk devices. Rather a flashing file folder icon with question mark appears when the machine is powered up without any user interaction.
With the EFI password active, it is necessary to hold the option key down, enter the password, and then select the desired disk device icon (either internal Linux or external OS X device) in order to boot the system. It appears that the system can no longer automatically select a boot device when started up, even if only one is available. This requires that every user of the embedded system must know the EFI password in order to start the system. This seriously compromises the protections that a user would expect to achieve by using the EFI password capability.
Is this the expected performance of the firmware after the EFI password has been activated, or is this performance the result of a design flaw in the EFI code when the firmware password is active (i.e. is this a"feature" or a bug)?

Welcome to Apple Discussions!
The EFI firmware protection is there for people who work in environments where their machines must be secure from intruders, and secures information in event the machine gets stolen. If that sort of protection is too much for your needs, just setup your security and account preferences to log out when energy saver and/or screen saver is activated, and automatic log on is disabled. That's pretty good unless a person who steals your machine or has access to your machine has the original discs which came with the Mac, or newer retail operating system (up to the limits of the machine's hardware). So consider how much security you need, and you can ask the system to be that secure.

How can I remove an EFI firmware password in a 2012 MacBook Pro Retina?

This computer was bought used. The SSD in it is dead, and it has an EFI firmware password blocking all my boot options. How can I remove it? The closest store is 400 miles away.

"YOU" CAN'T. You need to take the system to an Apple store or possibly an Apple Authorized repair center and ask them to remove it.
If you bought it used contact the original owner and ask for the password. Once you know that "YOU" can remove it.
If you come back with I can't get in touch with the original owner then I have no more help for you. Take it to your nearest Apple store.

How to create rescue and recovery partition for my thinkpad edge 11

Hi,
I'm using thinkpad edge 11 with win 7 home Premium 32 bit.
Before, i tried to restore to factory setting, there is a drive partition of rescue and recovery in my thinkpad.
But, when I was trying to restore to factory setting, I missed the steps and made the drive partition of rescue and recovery formatted.
So, now, I don't have it again in my thinkpad.
Then, after that, appeared another drive partition in my thinkpad with name S: Sytem, beside C: WIndow7 and D: Data.
So, I need the solution from you all as knowing more about thinkpad edge in this forum.
1. How I remove the unkwon drive, S: System from my thinkpad?
2. How I can create again the rescue and recovery partition on my thinkpad(wih Win 7 Home premium 32bit installer inside plus all the drivers)?
Thanks...

Hello mate,
To restore the Q: partition you have to use the Lenovo Recovery Discs. Hope you burn them before erasing the partition, otherwise you have to order them from Lenovo.
Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it.

H535s and recovery partition

Hiya,
Bought Lenovo H535s desktop from friend of mine. He has installed he's own copy of windows 8.1 on it, but i wanted to get it back to factory windows 8.1. Any idea how?
I have checked and i still do OEM and Recovery partitions on it untouched.
Cheers in advance,

hi mark_uk,
Welcome to Lenovo Community Forums!
Try turning off the computer first
Turn it back on then start hitting F2
If the partition is still intact and not damaged by the installation made it should provide options to get to Recovery.
If this failed, the only way now is to get Recovery CD from Lenovo (Fees may apply)

Firmware password and non-US keyboards

Hello everyone, I decided to post it here for your information. Anyone who have plans to set a firmware password to his Mac, and doesn't have a US keyboard, BE CAREFUL with the inclusion of symbols of its own keyboard layout (for example, I'm italian and so I've: "èàùéòì" but also "@" in different positions unlike the US layout). That because, as shown here: http://goo.gl/VJtOzA the system, during the setup will follow the classic layout of your keyboard (if you are Italian, "it-IT"), BUT during the insertion process it loads the default layout ("en-US") and so the symbols will be located in different places.
I have no idea why Apple did not warn of this thing in the process of setting!

Hopefully the following might help clarify my response:
If I had a work-around for this problem (other than the obvious "don't do that"), I'd have provided it.
If Apple were likely to see a problem report here, I'd have not passed it along to the Apple folks manually and directly. They've received and acknowledged the report.
If Apple were likely to see and act on problem reports and postings here, I'd have not suggested it be reported formally.
Unless the reports are in the Apple bug-tracking systems, I'd not expect to see the reports particularly considered.
Botching the keyboard handing for a password prompt is not something I'd consider appropriate behavior. I'd consider it a bug.
Whether  considers this a bug and worth pushing out a fix to the firmware and/or the bootstrap, I don't know.
For what it's worth, an article on Mac firmware and password processing from 2001 is exceedingly unlikely to be relevant to any current Mac systems. PowerPC (PPC) processors were used in 2001, and with completely different firmware (Open Firmware / OpenBoot, IIRC) than is used with the current EFI-based firmware present within all of the Intel-based Mac systems. Open Firmware / OpenBoot is very different from EFI / UEFI firmware.
I didn't follow the original shortened link, as I didn't know where that is going. One of the available link unshorteners translates that shortened link as a MacWorld article for OS X 10.1 which references Open Firmware password handling. In summary, it would appear that somebody else has created the same basic bug, a ~dozen years on.

I forgotten my bit locker password and recovery key.i need help .................

i lost my bit locker password and i lost recovery key,i need help ..please help ......such important things are there in my e drive....pls mail me [email address redacted]

Unfortunately if you lose the password and the recovery key you are not able to decrypt and access the information, that is the sole purpose of BitLocker.

How to create up-to-date Recovery Drive and Recovery Partition on Windows 8.1 U1.

I am running 8.1 and exploring the recovery options.
I'm periodically creating recovery images, etc. but would like to do better than that.
I'd like to know how to:
Create an updated Recovery Partition that will restore to a Recovery Image (WIM) that I choose.
Modify / Create a Recovery Drive that includes a system image
of my choice, as opposed to an image created by the manufacturer / supplier (and the extra work that that implies). If I can create an up to date partition and mark it as such, then I'm clearly done. Should I not be able to sensibly
make my own partition, how do I create this on a USB recovery drive? (The built in interface has a Boolean option, use hard drive recovery partition OR use nothing. This would be solved if it
also had an option to use current recovery image. I'm happy to write simple code to make this happen if that's what it takes.)
Put another way. I can make a recovery image at will, how do I create a recovery partition and recovery drive to match?
I'm no expert on the ins and outs of Windows 8.1 recovery, if this is already covered elsewhere, I'd appreciate a link.

I have documented an unsupported process for creating an automated recovery for use in a task sequence
here. However, if I read your post correctly you are suggesting being able to do this from USB media. The method for creating the recovery partition is simple. It is simply a partition containing a folder called RecoveryImage with your install.wim
inside. Reagentc is the tool that will actually tell Windows where that recovery is. While I don't personally have a use for what your suggesting, I may give it a shot just to see if it can be done. I suspect it will work.
Here are the links that got me started:

Accidentally deleted OS X and recovery partition

Hello, I was playing around with dual booting Ubuntu on my Macbook Pro and it seems like I accidentally deleted my mac partition. Only ubuntu boots on it now.
I tried all the recovery startup commands but none of them work, leading me to believe I also deleted the recovery partition.
Any help in reinstalling OS X on my machine would be greatly appreciated.

What is the EXACT model/year MBP that you have and what is the OSX?

EFI Firmware password question

Is there a commandline for the setting the EFI password using the Open Firmware Password Application ?
Thanks

Here's what I found:
Enabling Open Firmware Password
The Open Firmware password is a security feature available on modern Macintosh systems. If you enable the Open Firmware password, the computer will execute a secure boot sequence. Specifically, enabling the Open Firmware password prevents users from starting up the computer from a volume other than the chosen as the startup disk (chosen in the Startup Disk preference panel within the System Preferences.) Also, enabling the Open Firmware Password prevents users from booting into single user mode using Command-S key combination at boot time.
There is currently no public programmatic solution to setting the Open Firmware password (r. 3075615). This means this setting can not be set by an installer. However, an administrator can enable the Open Firmware password using the "Open Firmware Password" application located at: http://www.apple.com/downloads/macosx/apple/openfirmwarepassword.html
This was taken from Technical Note TN2062.
Sorry, but best I can do. Maybe you'll have better luck if you post the question in the Unix Forum.

Rescue and Recovery PARTITION not accessible

Hi,
I just wanted to reset my Thinkpad R52 (1846-CG) back to factory settings and therefore attempted to enter the RnR partion. After I selected the appropriate option in the boot menu, I got the following error:
Inf file txtsetup.sif is corrupt or missing, status 18.
Setup cannot continue. Press any key to exit.
I googled this error message, but all I could find was help concerning Bart PE and windows installation from USB-drives.... However this isn't my Problem...
Can anyone please help me on fixing this?
Every Idea, hint and/or suggestion will be very much appriciated, THANK YOU !

Hi,
the file "txtsetup.sif" is a so called "load file". This means, that this file usually contains informations on the load process , when you are starting into a Windows Pre Desktop area. This file hase always his specific loaction and in your case, what the error message want to tell you is that this file is missing and therefore the system has no imput on how to load all the files and library files, so that it can load the GUI <Graphical user interface> so that you can use your mouse, etc.
So in this situation I assume following:
You get this message, when you start the system and press F11, or the blue ThinkVantage button and after a short while it just shows you this error.
So here is what I would do:
- if possible start into Windows
- start the repair Rescue and Recovery => this should trigger RnR to "recheck" if all the files and folders are on the correct loaction and should basicaly repair also this file.
Please note, that you must use the same RnR version, so that nothing will go wrong. I would advice to check localy on your system or user Add/Remove programs to reinstall RnR.
Let me know, how it went.
Unforatunatelly I have not experienced such situation with RnR, but I did experienced it during my multiple Image deployments, where I have used WINPE.
Cheers
