How can I unlock my Mac Book Air if I don’t remember the 6 digit NIP?
Question by Shelbi Joseph /

My Mac Book Air got locked. It is asking for 6 digit NIP to unlock. But I don’t remember. Is there a way I can get the password or log in without this step or even reinstall the system? Any suggestion or help is much appreciated. Thanks in advance!

    If your Mac gets locked, the “easiest” way is to use your installation disc.

    Have you try CMD+OPTION+P+R ?

    I haven no idea what could ask for a “6 digit NIP” let alone what this is supposed to be.

    On a Mac there are only passwords which are also named that way:
    – a firmware password during boot (if set)
    – user/admin password e.g. on logon
    – FileVault password on boot if you encrypted your hard drive (10.7+)

    If iCloud does ask you for credentials it is your Apple ID (email address registered at Apple/iTunes/App Store…) and the appropriate password ~ nothing else, nothing “digit only”.

    The only things that will ever ask you for digits only (8 of them) on a Mac is when you connect your Apple Wireless Keyboard or when using the Migration Assistant via network.

    Whatever is asking you for 6 digits has to be some third party application and service. The only thing I can suggest at this point is doing a Safe Boot which disables all third-party services, start-up items etc…

    If that doesn’t work I suggest to revise what you installed on the system and what could cause this “6 digit NIP” lock.

    I am assuming you are talking about your OSX login password, I quick how-to on it  and have had a very high success rate with this method: http://richardcarpenter.weebly.com/1/post/2010/10/forgot-my-mac-password.html 

    If you have any questions, feel free to ask.

       No Mr Carpenter. It’s not the user/admin password. I think it is findmyphone/icloud NIP.It acepts only 6 numbers. Thanks

    If you have a MacBook Air, then why do you say your system is Windows?

    And what do you mean by 6-digit NIP?

    • Shelbi Joseph

       Mulder, I can’t log on to the system, so I have to use a window computer to post to MUO. It’s not the user/admin password. I think it is findmyphone/icloud NIP.It acepts only 6 numbers. Thanks

    if the password was saved to the firmware then will be difficult.

    •Hold Apple+S when booting to enter single user mode
    •#sh /etc/rc
    •#passwd yourusername
    •#reboot

    1) Insert the OSX install disc that came with the MacBook.
    2)Re-start the MacBook and when you hear the chime sound hold down the ‘C’ key.
    3)Choose the proper language and hit continue
    4)Now you will be at the installer. Choose Utilities and then Reset Password.
