    When I launch terminal and enter some sudo commands for example it starts the process and then at the end it shows a required entry for password that is locked ( the key symbol is locked ).

    Typing is now locked out.

    What’s that all about and how do i fix that ?

    1. blankMukhtar Jafari Reply

      Turn off your system then turns it on. Press and hold the command+s to navigate to the recovery mode
      Then type those commands that we’ve mentioned in the post.

    I upgraded to OS Sierra. I lost my login ability. It did not accept user password. I was searching for away to get my data back. I tried this with success. I lost my original username and was able to create admin user. After this I still did not have access to any of my files.

    Are there any other ideas? Can I revert OS back to the old way and get my files?????
