    I am having a problem with my refurbished recently bought macbook. But it sucks that the problem occured after the 90 days.
    I cannot install updates or even do anything without the administrators name and password. I set up the name and password when I first got it and when I log in it logs in fine but just when I want to install updates it gives me a message saying that : You must type an administrator's name and password to make changes to Software Update.

    And I know for certain that the name and password are correct but it keeps on giving me this message when I try make any changes. I have even tried changing the name and password as well but still no luck.
    When I type something that is wrong it would tell me : Sorry, you entered an invalid username or password.

    I tried calling apple but there no use because my 90 day technical phone line is finished.

    I have no idea what is going on. If anyone out there can help me I would be ever so grateful.

    Is your user account setup with administrator privileges?

    To check, goto System Preferences-->Accounts. Under you name, does it say "admin?"

    If it doesn't, is there a box to check saying "Give administrator rights to this computer"? Check that box. If not, maybe give this a try:

    -Insert Your Leopard DVD.

    -Shutdown and restart holding down C

    -Pick your language

    -from the menu go to Utilities

    -Pick reset Password

    -Pick your hard drive (mines Macintosh HD)

    -From the users list select system Administrator

    -Enter a password and renter it and select reset

    -Quit password reset

    -Then quit OS x installer

    -Click the restart button

    -When your system restarts go to system preferences

    -Accounts and click the unlock button (the padlock in the bottom left hand corner)

    -It will ask for user name and password

    -For user name use the name root and the password you entered in the password reset.

    -This should unlock all the greyed out menus.

    -Check the Allow changes box to give you back Admin status.

    -Restart your computer.
