    Unable to login after installing Mac OS X Mountain Lion on Macbook Pro

    Recently installed the mac os x mountain lion on my macbook pro, the installation completed with no major errors. After the installation ended I can't login with the the same account. Typing the same password does nothing here. What should I do now, any procedure to skip this step?

    Hello Friend

    1)You will Restart in single User mode.

    2)But remember that Single-User mode always uses the US English Keyboard Layout.

    3)At the Prompt, type this followed by Return.

    4)You will type the Below.

    Launchct1 load/System/Library/Lauchdaemons/com.apple.directroyservices.plist

    5)now press return. Type this , then press Return: is/Users.

    6)Look at the listing and note the short name of the affected user account.

    7)Type this dsc1.-delete/users/username AuthenticationAuthority

    8)Now again press return.
