Little Snitch, from the maker of the sublime LaunchBar, just got updated with a new Silent Mode that makes the app about a million times better to use, especially the first time you install it. Little Snitch is a network monitor that tattles on every other bit of software on your Mac, telling you when an app connects to outside servers.
That’s pretty much its only function, but Little Snitch Version 4 packs a ton of neat touches that tell you everything about how your Mac is connecting to the outside world. I’ve been using it for the past week or so, and it makes keeping your Mac safe far less annoying.
