Select the option Share files and folders using SMB (Windows), and then check any local Mac OS X accounts that you want to enable for sharing. Next, click Options (shown as “A” in the next screenshot). When you enable File Sharing, you simultaneously enable the Samba server service. NOTE: In previous versions of Mac OS X, the relevant option was named Windows Sharing. In the Sharing preference pane, enable File Sharing. In the System Preferences panel, in the Internet & Wireless icon group, open the Sharing item.
