How to customize the hostname in Mac OS 10.10

    This document is to show you how to change your Mac computer name through the command line and make it permanent.

    For hostname

    $ sudo scutil --set HostName MacBookPro  
    

    After the command is executed you can verify that the changes took place by typing:

    $ hostname
    

    You can also set a temporary hostname change by using the following command:

    $ sudo hostname new_hostname
    

    This will reset itself after your Mac reboots though, so if you want a permanent hostname change, use the above command instead.

    For share computer name

    $ sudo scutil --set ComputerName MacBookPro
