Because all the ports on your Mac Mini are open in a hosted environment, it becomes more important to deploy a firewall to control who can have access to what services. In this screencast tutorial I cover the built in firewall including:

  • The differences between a hosted Mac Mini and a home Mac Mini behind a router.
  • Some of the differences between the previous firewall version (IPFW) and the current one (PF).
  • How to turn on your firewall and what services to make sure to add to those that accept inbound connections.
  • The various features surrounding the built in firewall interface.
