I received a message "Installer is trying to install new software. Type your password to allow this." but I can't remember my password. Is there any way that I can retreive or reset my password? Thank you.

    Forgot Your Account Password

     

    For Snow Leopard and earlier

     

         Mac OS X 10.6- If you forget your administrator password

     

    For Lion/Mountain Lion

     

        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 downward pointing arrow button.

     

         When the menubar appears select Terminal from the Utilities menu.

         Enter resetpassword at the prompt and press RETURN. Follow

         instructions in the dialog window that will appear.

     

         Or see Reset a Mac OS X 10.7 Lion Password and

    If I do the second option, will it reset/erase all of the information from my computer? Also, I am not sure if I have snow leopard or mountain lion. How can I figure that out?

    You need to use the method corresponding to the OS X version you are running. The second option, for example, isn't going to work unless you have Lion or Mountain Lion installed. The method for Snow Leopard or earlier requires an installer DVD.

     

    There is not erasing your files.

     

    Select About This Mac from the Apple menu. It will display the installed OS X version.

    I believe I have the Lion version and when I tried option two it gave me a few options. I can't remember them all but one was 'search the web for help' and another was 'restore' and things like that. I'm sorry, I can't remember the options exactly. What do I do after that?

     

    And thank you so much for all of your help so far. It really means a lot!

    Use the second option and follow the given instructions. Be sure you read them carefully, because I haven't a clue to what you are referring.
