Can someone teach me how to reset it? I do know that 2. is invalid already. I'm running a Macbook Pro Late 2011 on OSX Mavericks

  • How to reset a firmware password?

    do you know how to reset the firmware password on a workstation ultra 30?
    each command on the ok prompt ask me for a firmware password. i tried (of course unsuccessfully) several.

    @rukbat,
    You are partially correct. It depends if the security-mode is set to "command" or "full" (and if auto-boot?=true). If it is set to command, he can put in the other systems disk (in the same slot) and enter "b" to boot, then enter the eeprom command as root after he logs in. However, he cannot boot to cdrom because the boot-device is directed to the hard drive and cannot be changed without the eeprom password. I have used this technique to set security-mode=none on several E250s in years past.
    If it is set to "full", his only option is to enter the password and log in to get an OK prompt, which leaves him where he currently is.
    You dont have to get your prom from SUN. The SUN part number for an Ultra30 prom is: 525-1669, which you get several hits on if you search. IIRC, anysystems.com doesn't list the part but they can probably help you out.

    It would block usage of all the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option, and Shift, as well as booting from anything but the Hard Drive.

    Forgot Your Account Password
    For Snow Leopard and earlier
         Mac OS X 10.6- If you forget your administrator password
    For Lion/Mountain Lion
        Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
         When the menubar appears select Terminal from the Utilities menu.
         Enter resetpassword at the prompt and press RETURN. Follow
         instructions in the dialog window that will appear.
         Or see Reset a Mac OS X 10.7 Lion Password and
         OS X Lion- Apple ID can be used to reset your user account password.
    If you are unable to boot from an installer DVD:
    (these will only work on Leopard or earlier)
      1. Boot to Safe Mode by restarting and after the chime press and hold down
          the COMMAND-S keys until a black screen with white type appears.
      2. At the prompt, type the following commands pressing return after each
          command line:
         /sbin/fsck -yf
         If you do not receive a "Filesystem OK" message then repeat this command
         until you do.  If after seven tries you still do not receive a "Filesystem OK"
         message, then the system is corrupted and needs to be reinstalled.
         mount -uw /
         cd /private/var/db/netinfo
         mv local.nidb local.old
         rm ../.AppleSetupDone
         shutdown -r now
    The second-to-last command above will cause OS X to think that the operating system is newly installed, and when the new owner starts up the computer it will send him/her to the startup wizard where he/she can start a new user without reinstalling.
    This last method does not actually change a password. It simply removes the user accounts and lets you create an initial admin account as if the computer were new out of the box.
    Reset Admin Password Using The Terminal
    You can reset the password by printing out (or writing down) and carefully following these steps.
    First, find the short name of the admin user on the machine. The easiest way of doing this is by looking at what the directory is called in the Users folder.
    Now, start in Single-user Mode. It should boot into a command line.
    Enter these exact lines. Press RETURN after each.
    mount -uw /
    ifconfig lo0 up
    cd /var/db/netinfo
    netinfod -s local
    Now you'll need that short name. Enter "passwd", a space, and the short name of the admin. For example, if the admin was rather prosaically called "imadmin", you would enter "passwd imadmin".
    The computer will now prompt you to change the password for "lmadmin" (or whatever the short name was). Go ahead and enter a new password.
    Now, enter:
    sync
    reboot
    and the machine will reboot. The admin password should now be changed.

  • How can I reset my firmware password?

    Hi when I bought my macbook pro second hand, I didn't realize there was a firmware password for the computer making it impossible to enter the boot options menu. I have tried the password that came with the computer and my user password and neither worked, so how can I reset the password? Is there a general default password? Any way I could do it without going to the apple store as the nearest one is three hours away and I don't have transportation to get there.

    Welcome to Apple Support Communities
    You can only reset the firmware password if you know it. Also, you need to start from OS X Recovery or the OS X disc in order to reset it, so it's not possible to do anything else. The only thing you can do is to take your computer to an Apple Store or reseller, because there's no way to reset your firmware password that we already know

  • Resetting a firmware password when never put a firmware password on Macboo Pro OSX Lion

    I have never put a firmware password on my Macbook Pro OSX Lion (2012). But now when I am trying to reset it, its asking for a password how can I reset this or remove it.

    Hi macbookprowilliam, I have the SAME problem, that grey lock just appeared trolling me. I dunno the password and I wan't to sell this macbook! I need the password. Maybe it's a new malware!

    So, did you fix it or got around it? Please reply! I am desperate.
    Thank you

  • I cant figure out how to reset my security password

    i cant figure out how to reset my security password so i cant buy any apps can anyone help

    If you've just added an address to your account then it will be an alternate/secondary email address, a rescue email address can only be added by answering 2 of your security questions. If you already had one on your account then go to https://appleid.apple.com/ and click 'Manage your Apple ID' on the right-hand side of that page and log into your account. Then click on 'Password and Security' on the left-hand side of that page and on the right-hand side you should see an option to send security question reset info to your rescue email address.
    If you don't have a rescue email addressthen you will need to contact iTunes Support / Apple to get the questions reset.
    Contacting Apple about account security : http://support.apple.com/kb/HT5699
    When they've been reset (and if you don't already have a rescue email address) you can then use the steps half-way down this page to add a rescue email address for potential future use : http://support.apple.com/kb/HT5312

    There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
    1. Boot from your recovery partition (10.7 or later), a local Time Machine backup volume (10.7.2 or later), or your installation disc (10.6.8 or earlier.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
    How to back up and restore your files
    2. If you have a working Mac, and both it and the non-working Mac have FireWire ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive.
    How to use and troubleshoot FireWire target disk mode
    3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

  • Firefox crashes when I try to reset the master password using chrome://pippki/content/resetpassword.xul

    # Question
    Firefox 3.6.10 on Windows 7 crashes when I try to reset the master password using chrome://pippki/content/resetpassword.xul. Is there an alternate way of resetting the master password?

    You can delete the 2 files that contain password details, they will be re-created automatically. First open the profile folder, for details of how to find it see the [[profiles]] article. Now close Firefox and delete key3.db and signons.sqlite. If there are files called signons.txt, signons2.txt and signons3.txt you can delete those as well, they are from earlier versions of Firefox.
