How to recover my administrator password in OS X Lon 10.7.5 on Macbook 13-inch, Early 2009

I have a macbook 13-inch, Early 2009
and installed Lion 10.7.5
How can I recover or resset my admin. password?, because I put that I remember but is incorrect.

The only way to reformat (erase) and restore to factory settings is by booting from the install disc that came with the Mac. Apple install discs are, "machine specific" meaning they can only be used on the Mac they shipped with.

    How can I recover my administrative password without paying a fee?

    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Utilities from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access the Menubar at top.

    Terribly sorry Joseph Kriz. I had absolutley no intention of annoying anyone. This was the first time I have been communicating in a discussion group, and as I wrote my comments I had no idea how my typing would reflect and where my question would be going. Hope my unintentional typing will be forgiven and causes no further agitation.The only additional comment I can make on your response is that "I do not use capital letters or CAPS LOCK while I try to enter my administrator password". Thank you for guiding me

    Hi BobRz,
    As this is a new issue for me, I believe I had the incorrect approach, maybe you can help me. What I want to do is recover a few files in my desktop, and some information i had on the iCal application and the Mail application as well.As I do not want to do a full migration into this computer (which is not mine) I believe that starting the damaged MBP in Target mode should allow me to search and cop the files I need. But:
    1. Can I open the Ical and mail apps to look for the info I need while reading it as an external HD  ?
    2. Do the target machine (my friends) still need to be updated to ML o Mavs so that it recognizes my MBP as an external drive if starting it in Target mode ? (no migration assistant)
    Thanks.

  • How to recover BIOS Admin password on HP ProBook 4740s?

    Excuse me, do you know how to recover BIOS Admin password on HP ProBook 4740s?

    Hi,
    Unfortunately,  business machines such as Probooks or Elitebooks have more stringent security than consumer models - they don't produce 'halt codes', the password cannot be derived from the Serial No. and the code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case.
    If you Contact HP Business support they should be able to send you a customised SMC.bin file which you can use at boot to reset the password.
    Regards,
    DP-K

  • How to recover a lost passwords?

    Hi everyone,
    I recently tried to help a friend in installing software she has for her Mac.
    I was prompted for a password but she could not remember what her password was since she has not installed anything for a while.
    I thought it was kind of careless of her not to write it down but I did not give her a speech about it.
    Can anyone inform me how to recover of change passwords please?
    Or a link to instruction please?
    Rio.

    NOTE: The following information has been publicly disclosed on a number of Internet sites, and is not a new find. I'm simply repeating it here for the sake of completeness.
    Read the detailed section of this article for step-by-step instructions on regaining access to your root account.
    Originally posted by QuantumFusion on the MacNN forums, and repeated with slight readbility changes, here are the steps to regain access to root:
    Click Restart at the login window
    While the computer is restarting, hold down "Command-S" until you see text scrolling through the window. This boots the computer into single user mode.
    At the Localhost% prompt type:
    /sbin/mount -uw /
    /sbin/SystemStarter
    You will then see various services starting up.
    When the Localhost% prompt reappears, type:
    passwd root
    It will then ask you to type the new root password twice, so do so.
    After entering the new password, type:
    reboot
    At the login window, enter username root wih the new password. Once you are connected, you can use the Multiple Users application (/Applications/Utilities) to change your normal user's password, or create a new user account.
    Good luck.

  • How to recover my administrator passcode

    How can I recover my administrator passcode on my MacBook?

    You can't recover it but you can change it. Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive. When it does start up, you'll see a panel asking you to choose your language. Just press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Reset Password.

  • How To Recover A Lost Password

    I don't know the administrator's password, does anyone know how to recover it? I am the administrator, and I'm posting this from a standard account. Not being able to log into MY account limits what I am able to do.

    I don't believe you can recover it. You can reset it without knowing the old one:
    http://docs.info.apple.com/article.html?artnum=106156
    and scroll down to the last section. You'll need to boot from an install CD.

    Did you disable UNIX group and ENS login authorities? Check with:
    # /opt/tarantella/bin/tarantella config list --login-ens
    # /opt/tarantella/bin/tarantella config list --login-unix-group
    They should both return 1. If not use config edit to set them accordingly.
