How do i reset admin password. no disc but system automativally logs me in as administrator and can access root user mode

I recenly got this macbook, MA&00LL/A, max OS X, V:10.4.11, 2GHz IntelCore 2 duo, 2GHz, When I power up it automatically logs me on as administrator but prompts for password when I try to access/change certain features.  I got the macbook from my cousin who has forgot password and has lost disc.  I can access root user mode but as iam unfamiliar with apple I am hesitant to delete anything without making things worse. Is their anyway I can reset this admin password without the disc or simply delete this user and reconfigure system as myself as administrator. step by step instructions would be appreciated at this stage till i familiarize myself more.  Any help would be greatly appreciated.  If it came down to buying a disc, how much roughly do these cost???  thanks again

If you don't have your install disks you can get the 10.4 gray disks by calling Apple Store Customer Service at 1-800-676-2775 They can send them to you for about $16 per disk plus S & H. Just give them your serial number and they'll know which ones you need.
To find your serial number go to the Apple in the upper left corner and select About This Mac, then click on More Info, the System Profiler will then come up. The Serial Number (System) is down near the bottom of the Hardware Overview list.
If you don't have your install disc handy,then follow these steps
1. Start up in single-user mode (hold Command-S as thecomputer starts up).
2. Type: mount -uw /
3. Press Return.
4. Type this: passwd (user's short name) Replace "(user's shortname)" with the short name of the user account whose password you wish to reset. If you are not sure what the account name is, you can get a list of usernames by typing: ls /Users
5. Press Return.
6. Enter a new user password.
7. Press Return.
8. Type: reboot
9. Press Return.

  • How do you reset Admin password (when not logged in as Admin)??

    Here's my predicament. I set up 3 accounts on our laptop - one for me and my wife (Standard accounts) and a House Account as the only Admin. Now, I don't remember the password for the House Account, which serves as the Admin.
    I am trying to load new software, but it request administrative privileges. To make matters worse, when I try to install the MAC OSX startup disk (like the help manual says you should to reset the admin password), before my computer will restart the startup disk, it asks me for the Admin password. Because I am not logged in as the Admin, I can't even restart the computer when prompted by the startup and install the OS again.
    Any suggestions or help with this issue?
    Eric

    Did you create an Open Firmware password as well? If not then just insert the OS X Installer Disc into the optical drive and restart the computer. After the chime press and hold down the 'C' key until the spinning gear appears below the dark gray Apple logo.

  • I'm trying to access a forum that requires a user name and password.  When I do it on my mac it tells me the password is incorrect but when I do it on my iPad, I can access it without any problem.  I can confirm the username and password are the same

    I am trying to access a forum for which you need a username and password but it keeps telling me the username/password i've entered are incorrect.  Bizarrely, when I enter the same username/password combination on my iPad, it grants access without any problem. 
    What could be causing this, is it an issue with cookies, caches or similar.  How can I resolve it?  The forum administrator is at a loss as to what the problem is.

    Try the following steps in Safari to see if they help:
    1) First try clearing the Safari cache.  To do this pull down the Safari menu and select 'Empty cache...', then try logging into the site again.
    2) If the issue continues then reset Safari by pulling down the Safari menu and select'Reset Safari...'. You will be presented with a list of items that can be reset. I suggest selecting the 'Reset saved names and passwords', and 'Remove all website data' options at a minimum.
    Here is a list of the options and what they do. I pulled it from the Safari help page.
    Clear history:
    Clears the list of webpages you viewed.
    Reset Top Sites:
    Clears any changes you made to Top Sites, such as adding or pinning sites. If you also clear your history, your Top Sites page reverts to showing the webpage previews displayed when you first installed Safari.
    Remove all webpage preview images:
    Clears any thumbnail images Safari saved of webpages you viewed.
    Clear the Downloads window:
    Clears the list of files you downloaded from websites. Only the names are removed; the files themselves are still on your disk until you remove them.
    Remove all website icons:
    Removes website icons, which are small graphics that help identify sites on the Internet. You see them in the Safari address field and bookmarks list, and other places. These icons are stored on your computer.
    Remove saved names and passwords:
    Removes user names and passwords that Safari automatically fills in at websites that require them (if the AutoFill feature is turned on).
    Remove other AutoFill form text:
    Removes some personal information, such as telephone numbers, that Safari uses to automatically fill in forms on webpages (if the AutoFill feature is turned on). Removing AutoFill information does not remove information from your address book.
    Close all Safari windows:
    If you don’t close all Safari windows, someone could use the Back and Forward buttons to view the webpages you visited.
    Reset all location warnings:
    Clears any information websites saved about your location.
    Remove all website data:
    Removes cookies, tracking information, and other data that websites stored on your computer.

         mv local.nidb local.old
         rm ../.AppleSetupDone

    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.

  • I recently inherited a power mac from my dad how do i change admin passwords and such so I can use it

    I recently inherited a power mac from my dad how do i change admin passwords and such so I can use it?

    And if you can't log into the machine at all, you'll need:
    Mac OS X: Changing or resetting an account password.
    You'll need a system recovery or Mac OS X install disc. Don't drop your Dad's user account, though. If he's got any serialized software, it may not function for all users on the machine, and you may need to go back to his account.

  • Reset admin password in Weblogic 9.2

    How do I reset the admin password in Weblogic 9.2?
    I attempted to create a new user with the following:
    java weblogic.security.utils.AdminAccount adminuser weblogic .
    and renaming the boot.properties file, but the server does not start. I get the following error (after starting weblogic and entering in the newly created username/password):
    <Jan 12, 2009 5:51:08 PM MST> <Critical> <WebLogicServer> <BEA-000386> <Server s
    ubsystem failed. Reason: weblogic.security.SecurityInitializationException: Auth
    entication for user adminuser denied
    weblogic.security.SecurityInitializationException: Authentication for user admin user denied
    I feel that I am missing something obvious to reset the admin password. Any help is appreciated

    This is a very useful thread and definitely works. The above Python code is proper, only that Python requires indentation, and would not work otherwise.
    The reason everyone seems to be having problems running this code is because the intentation is missing. See my modified code below. I have put in </tab> to indicate there indentation should be. Simply replace </tab> with an actual tab using Notepad++, Textpad or a similar text editor. I have also made a little modification as I could not get the username and password to display correctly with the above code. The code has complex path processing in function processBootFiles(rootPath, processFunc) which perhaps misses out on the main boot.properties file, even though its coded in.
    The key is in getting this function to run explicitely: processFunc("./boot.properties"). Please check the paths for your wlst.sh/.cmd installation and ensure that you are currently in the directory with boot.properties file and run a command to call wlst & this script (call it wlsdecrypt.py) from that directory. This will work and indeed display the username & password :-)

  • How do a reset my password on my iMac

    If its your admin password, then reboot into recovery mode: (Holding down Command+'R' as it restarts.
    Then when you get to the Mac OS X Utilities, go to 'Utilities' at the top and select 'Terminal'.
    When the terminal opens up, type in 'resetpassword'.
    It will open up a window where you can reset your admin password. Then just reboot and you'll be good to go.

I have tried with a newer installation disc "tiger" and this does not work. Can anyone help me.

  • Resetting admin password from non-original CD

    We have a 400 Mhz Powerbook G3 running Mac OS X 10.3.3. We got it from eBay as is––no CD's, no other information. Now that I have inadvertently locked System Preferences, that is a problem because we do not know the admin password.
    I see that you can reset the password by booting up from a Mac OS install disc. My question is, would it be possible to do that using the OS X install disc for v. 10.3.7 that came with my iBook G4?

    Usually the OEM install disc that comes with a particular computer model will not work with other models. However, you can give it a try. If you can get it to boot the Powerbook, then after the installer loads select Reset Admin Password from the File menu.

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

    View Solution.

    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.
