• Automatic Profile Switching:

  This new feature allows you to assign networks (for example your Wi-Fi network at home, a public hotspot, etc.) to certain profiles. Whenever you join one of these networks, Little Snitch detects the network change and switches to the associated profile automatically.

  When you join a network for the first time, Little Snitch shows an alert window allowing you to choose the desired profile. Alternatively, you can configure a default profile that will be used for all unknown networks.

  The mappings between profiles and networks can be reviewed and edited later in Little Snitch Configuration, either in the profiles section of the sidebar, or in the new “Known Networks” window (⇧⌘K).

  Automatic Profile Switching is disabled by default. It can be enabled in Little Snitch Configuration > Preferences > Automatic Profile Switching.
