How to reset EFI password ??

i got stuck on efi password . how to reset and can i update my os without efi password ??

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 arrow button below the icon.
From the menubar select Firmware Password from the Utilities menu.
Yes, you can upgrade software without a firmware password, but you do need an admin password for your login account. I think you have these two confused.

  • How to reset master password?

    Hi Experts,
    I have installed NW CE 7.1 and NWDS 7.1. It got installed successfully. During installation it asked me for the master password that will be used for all users. I have provided the password as "password1". But now it is not working for any of the users when I try to login. I tried with users "j2ee_admin" and "SAP*".
    Please help me to figure out what could be the problem. Or how to reset the password.
    Thanks in advance.

    1)Your going to have to go to the manufacture's website for the orginal password. Once you have that you will have to setup you network again.
    2)After your network is setup again you will go to general setting menu on the ATV. Select the Network option then Configure Wifi option. It will take a momment and load all the WIFI networks in you area.  Once you selected your network, it will prompt you to enter the password.

    There is no reset if you can't remember it. You'll have to restore as a new phone & delete your existing backups & start over. I'd suggest you try & remember it.

  • TS2446 i am trying to reset my security passwords but it will not let me. I have read alot of articles and i cant seem to find how to reset the passwords, Please Help.

    I am trying to reset my security passwords because i have forgotten them. i have read other articles but i still can not seem to figure out how to change these passwords.

    If you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then you can try going 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 might see an option to send security question reset info to your rescue email address.
    If you don't have a rescue email address then see if the instructions on this user tip helps : https://discussions.apple.com/docs/DOC-4551
