• AirPort — If WiFi is not necessary, go to System Preferences > Network and “Turn Airport off.” Then head to “Advanced” and click on the TCP/IP tab. Set “Configure IPv6″ to “Off.”

• Software Update — [R]egularly applying system updates is extremely important, says the NSA. Go to System Preferences > Software Update, click “Check for updates” and set to daily

• System Accounts — Go to System Preferences > Accounts > Login options and disable Automatic Login. Set login to display name and password.
