This is a collection of OS X configuration options that I recommend for new setups. Most of these recommendations are security related. Currently, this information is based on OS X 10.6 (Snow Leopard) options but may be applied to older versions.

These are general recommendations. Obviously you may a need to choose different settings (for example, don’t disable the remote control if you use one).

Simple Desktop Lock

• In Exposé & Spaces Set a Hot Corner to “Start Screen Saver”
• Under Security -> General enable “Require password [immediately] after sleep or screen saver begins

System Preferences -> Security -> General

• Enable “Disable automatic login”
• Enable “Log out after [30] minutes of inactivity”
• Enable “Disable remote control infrared receiver” (or pair with a specific remote)

System Preferences -> Security -> Firewall

• Ensure that your firewall is on and review the specific settings under “Advanced”.

System Preferences -> Network

• “Ask to join new networks” should be enabled (I think this is on by default)

System Preferences -> Bluetooth

• Turn off Bluetooth when it’s not needed

System Preferences -> Sharing

• Change “Computer Name” to something more relevant
• Choose “Edit” and also change the computer name there
• Turn off all services that are not needed
• Ensure that enabled services can only be used by the proper accounts
• In public networks it his highly recommended that all services are disabled

System Preferences -> Accounts

• Disable the “Guest Account”

System Preferences -> Date & Time -> Time Zone

• Ensure the time zone is correct
