With a firmware password enabled how to boot in to an other volume?

I found this:
Some startup keys don't respond if both firmware password protection and FileVault 2 are enabled
Some startup key combinations that you can use when your Mac starts, such as those which use the Option or Command keys, may not respond if a firmware password has also been enabled.
If you have a firmware password enabled on your Mac, you must successfully enter that password before you can boot to another startup volume, or before you can access the Startup Manager.
Is it not so that if I boot from lets say a DVD or External HD, I will be asked for the Firmware PW before being allowed to go on?

I haven't tried it with FileVault so I can't tell you the answer for that question, but note that FileVault only affects to the internal drive, which would mean that you are not asked for FileVault. Another user has to confirm this

With Multi-Factor Authentication ENABLED how can office 365 admin connect remotely to manage Office 365 with Power-Shell ?
When I key-in my credentials, auth fails with invalid username and password ?
Does any know the procedure ?

This question was closed over a year ago. You will need to start a new question. You can post a link back here if you think it helps.
I also recommend asking in the O365 developers forum for how to do bulk license upgrades. You can use the answer here and just remove and then add the new license.

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

Can you still access Windows partition with open firmware password installed?

Can you still access Windows partition with open firmware password installed? If so, do you still use the Option key upon restart?

I don't use Bootcamp. However, I do know that with a firmware password, pressing the option key at startup will cause the password entry screen to come up; after entering the password, you will get the boot device choice screen.
So, if Bootcamp partitions normally show up on that screen then it should work just fine, or so I'd imagine.

Zap PRAM with Open Firmware Password?

I'm wondering if there is any way to do this...
I have an older MacBook that had some kind of issue recently, that first prevented it from booting at all, and after resetting the SMC it would boot but the screen is black...
I remember from many years ago that there was an issue with the screen staying black that would be fixed by zapping the pram...
Problem is the system has an Open Firmware password. And while I do know what that passowrd is, it's kind of impossible to go in and disble it with a black screen...
In essense, is there any possible way I can zap the PRAM that doesn't involve psychicly guessing what I'm doing???

I'm fully aware of the key combination. The problem is when Open Firmware password is enabled, holding CMD-OPT-P-R has no effect.... The only way I know to be able to use the key combiantion is to disalbe the Open Firmware password first, then reboot and hold hte keys down.
Which is where my problem lies, as I can't zap the PRAM until I disable my Open Firmware password, and I can't go though the steps to disable my Open Firmware password until after I zap the PRAM in order to re-enable my screen...

Missing firmware password, can't access boot options

Hi,
I own a Macbook Pro (13") which I bought from Ebay a few months ago. I recently changed my password to my administrator account, but I cannot remember it. I know of several bypasses to this, but as I attempt each one, they all seem blocked by a firmware password. I have tried contacting the original owner, but he does not remember what he set that as. I'm locked out of all boot options and my administrator account, I'm typing this now from the guest account which I enabled a while ago. Solutions?

If your MacBook is one of the following models there is no way to circumvent a firmware password, outside of a trip to the Apple Store:

How to get them please?
===========================
Sorry - no - all well, they seem to be all coming back - back just after I put this question.
Mysterious to me but very satisfactory.
Profile doubtless that of an ignoramus.

Ok, so I was able to find one but the one i'm most diappointed is the "free music" app i purchased and it had hundreds of songs that i didn't put on my desk top to save. So just so we're clear, I cannot get that app back again with all my songs if it wasn't in the "purchased" place?
Also,
my husband has a iphone 4 and i've been trying to connect it to our Garmin GPS through bluetooth. Now both devices recognize it but once a call is made or received, nothing goes through the GPS. I've had it working before but it was before a couple of upgrades. It is currently on ios7.2 upgrade. Is that why it won't work?
Thanks

Help with Open Firmware Password Utility

Hi,
I tried to run the Open Firmware Password Utility on Kittendaddy's indigo iMac (running Tiger 10.4.11) and nothing happened. The app acted like it was going to open, but didn't.
I found the app here: www.apple.com/support/downloads/openfirmwarepassword.html
What did I do wrong?
Thanks in advance!

Thanks, everyone. Unfortunately, it looks like Kittendaddy's iMac may have died the true death earlier tonight (and it had nothing to do with trying to install the open firmware password utility!). I just hope I can get it to start up one last time so I can get his music off it.

Does time capsule backup two separate users with their individual passwords or how do you set that up?

I Have two separate users on my computer and want the backups to reflect that. I don't want one user to have access to my stuff and vice versa. Does time capsule do this automatically or do you set this up somehow?

TM does the whole computer.. it is designed for home setup.. where people not that worried about security.
It is always possible for any user to access any other users account.. given enough time and skill. TM backups make it easier in a way.. I have tested it myself and I can recover TM backups from unknown user in a Time Capsule with an unknown password. It was tricky but anyone with brains can read the net.
There are solutions.. as I said.. if you are worried you should be using Encryption. Never depend on passwords in a shared computer to prevent access.
If your files are encrypted then even if a person recovers them they cannot read them without the key.
It may need for your files to be on a separate partition.
See Pondini's info on file vault and interaction with Time Machine.
http://pondini.org/TM/25.html
Of course for a person to hack in.. they have to want to do it.. in most people's home situation that is not a hassle.
For a business setup you would be using superior security.. proper active directory server etc.

After downloading Mozilla Firefox 4.0 Beta to my desktop I restarted the computer, but I do not receive any prompts to create an account with a Secret Password. How do I set up the account if the prompt never show up?

Several months ago I installed the Firefox Home app on my iPhone to sync the bookmarks that I had on my Windows XP home computer. It has worked just fine until a few days ago. Just recently I was notified that the app would no longer work because of changes that have been made. I have tried to follow the instructions that were emailed to me regarding how to setup the new Firefox Sync add-on, but I am having a problem. After downloading Mozilla Firefox 4.0 Beta to my desktop and restarting my computer, I do not receive any prompts to create an account with a password and a secret phrase, as the instructions specify. How do I set up the account if the prompt never shows up?

Click on the Firefox button then select Options to open the Options dialog. Now go to the Sync panel for the option to setup a new account.

Disable Firmware Password

Hello, I'm running OS X 10.5.1 on a MacBook Pro 17", 2,4 GHz Intel Core Duo.
I have enabled the Firmware Password with the Tool that was offered on the Install DVD.
It seems with the firmware password enabled i am no longer able to reset the PRAM by holding down the altcommand+rp keys on startup.
Is there any other way to reset the PRAM? Or, is there a way to disable the firmware.keyword? I only found options to change it.
Thanks in advance.

hello - first of all: thanks for the quick response!
i just found a solution myself on retry, it is even simpler:
boot from cd, select the firmware password utility, then unmark the box sying something like "require password for editing firmware settings" (i use a german localization of os x leopard).
that's all.

Firmware Password Question

I just enabled firmware password protection for my MacBook. Everything is working as advertised but I just have to ask this question.
Anyone with a Leopard install disk can change you account password or firmware password. Is this correct?

What Niel means is that if auto login to the admin account is turned on, then the Startup Disk preference pane may be unlocked. This will allow the user to set a Leopard DVD as the startup disk, without further authentication.
no, that pref pane is always locked unless you manually unlock it with the admin password. automatic login doesn't change that. the same is true with the accounts pref pane. you don't need to unlock that one to change the password of the current user but you do need to enter the current user password in the password change popup. such obvious security holes are plugged in. but you are right about the firmware password not giving data protection in case of theft.
The firmware password simply prevents booting up from any other disk that isn't the set startup disk. A Mac with a firmware password set will still boot up from DVD if the DVD is set as the startup disk.
Once booted up from the Leopard DVD, the admin password may be changed without knowing the old one.
As a side note, many people misunderstand the use of the firmware password, and believe it will protect them from data theft if their Mac is stolen. It won't, because it can be easily defeated without knowing the password. Encryption is the only way to go to protect yourself from data theft.

How can I enable firmware password for normal boot?

I've enabled firmware password protection, but it won't work unless you try to boot in other mode ( like holding c, d or option to boot from other drives ). However, what I want is a complete lock from opening my computer. Is there a way to enforce this?
Best Regards

Even if with the firmware password, you're not safe. There are ways to bypass both the firmware password and the login password. To be as safe as possible:
1) Turn on the firmware password, as you have done
2) Turn off auto-login, so that users have to log in to use the machine
3) Set the login window to ask for name and password instead of displaying a list of users
4) Use good encryption with a good password to protect any sensitive data
or,
4b) Don't ever let the machine out of your sight!
Disk Utility can help with #4 through use of encrypted sparse disk images on which you store sensitive data. File Vault can also help by encrypting your entire user folder, but IMHO this is a bad idea unless absolutely necessary, as it complicates backups and means that any little disk corruption could trash your entire user directory (since it'll be stored in one big, encrypted file).

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.
