Last week’s mac techmail was Protect your privacy with Little Snitch for Mac which talks about Little Snitch, one of my absolute favourite and essential mac software tools. Little Snitch is an outbound firewall, so it will alert you if any applications try to make outbound connections (anything from a new browser trying to get out and connect to port 80, or curl from the command line). So many apps try to self-update or phone home, Little Snitch makes it easy to allow what you trust, disallow what you don’t want, and allow on a case-by-case basis everything else. Awesome application.
