  • HT1752 I have forgotten my admin password and need to create another user

    I have forgotten my admin password and need to create another user. Have no disks to boot from!!

    You need an installer disc in order to reset an admin password. I don't know if the following will work on your system, but give it a try:
    You can also 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 their directory is called in the Users folder.
    Now, start up the computer while holding down Cmd-S. It should boot into a command line. (If it doesn't, you may need to reset the firmware password, which is detailed elsewhere.)
    Type these exact lines:
    mount -uw /
    ifconfig lo0 up
    cd /var/db/netinfo
    netinfod -s local
    Now you'll need that short name. (You did write it down, didn't you?) Type "passwd", a space, and the short name of the admin. For example, if the admin was - rather prosaically - called "admin", you'd type "passwd admin".
    The computer will now prompt you to change the password for "admin" (or whatever the short name was). Go ahead and type a new password.
    Now, type:
    sync
    reboot
    and the machine will reboot. The admin password should now be changed.

  • Have just bought an ipad but have forgotten my gmail password.  I have used this gmail account for my apple id, if I set up a new email account on the ipad , do I have to change this apple id.  Am a very confused novice!!!

    I have recently bought an Ipad but have forgotten my gmail password that I use on my Mac.  I have used this email as my apple ID.  If I now set up a new email account on my Ipad, do I have to change my apple ID as well as my apple password!  HELP A VERY CONFUSED NOVICE!!!

    On your Mac, try to access your gmail account. There should be a link you click for "Forgot My Password". Click it and try to retrieve your password.

  • I have forgotten my appleID password and the email it is linked to is deactivated, security questions aren't working. This is on my iPhone and iTunes acs so I can't sync with my new computer. How do I merge AppleID accounts and shut down the old one?

How do I merge AppleID accounts and shut down the old one (when I have no password and the security questions aren't working?)

    You cannot merge Apple ID accounts, that has never been supported.
    You can contact the Apple ID Security folks per the listing in http://support.apple.com/kb/HT5699 and they can help reset security questions and get the account working.

    Hi,
    If you normally sign-on with an email and password, you can reset the password via another PC from the Microsoft page on the following link.

  • I have forgotten the iPod password.

    I have forgotten the iPod password.  How do I start over so I can use it with iTunes?

    Hello Larry
    What you would need to do is put your iPod nano into Disk Mode and then plug it in to your computer to then restore it in iTunes. Check out the article below for the steps to do that.

  • I have forgotten my administrator password and can't find my Mac OS X Install Dvd..what can I do?

    I have forgotten my administrator password and can't find my Mac OS X Install Dvd to reset it, what can I do?

    OK, try this:
    http://osxdaily.com/2010/08/10/forgot-mac-password-how-to-reset-mac-password/
    Be very very careful if you decide to use Terminal. Even a small typing error can cause a disaster. And terminal commands must be typed exactly as shown, including spaces.
    Good luck.
    p.s. Your Apple ID and password - different from the computer log in password - are what you used to get to this discussion.

  • I have forgotten my administrator password, and there are no hints. I have a Mac OS X Mavericks. When I get to the reset password screen, it has no hard drive to select. What now?

    If you're using FileVault, you first have to unlock the startup volume in Disk Utility. Select it and click the Unlock button in the toolbar. Of course, this is only possible if you know another password to unlock the volume. If you don't, follow instead these instructions.

  • I was trying to update my ipod to iOs 5 but I have forgotten the backup password

    I was trying to update my ipod to iOs 5 but I have forgotten the backup password help please?

    You need to restore your iPod to factory defaults/new iPod.  That is the only choise.
    Warning: If you encrypt an iPhone backup in iTunes and then forget your password, you will not be able to restore from backup and your data will be unrecoverable. If you forget the password, you can continue to back up and use the device, however you will not be able to restore the encrypted backup to any device without the password. You do not need to enter the password for your backup each time you back up or sync.
    If you cannot remember the password and want to start again, you must perform a full software restore and when iTunes prompts you to select the backup from which to restore, choose set up as a new device.
