    In the “Finder“, select the “Go” menu, select “Connect to Server“.
    Enter the address to where the resource is you wish to map in the “Server Address” field. (i.e. smb://servername/foldername)
    Select the + button to save the Server Address to your list of “Favorite Servers“.
    Enter the username and password that is required to access the resource. Check the “Remember this password in my keychain” box if you wish to store the credentials for use at a later time.
