After setting up defaults, it monitors the user's system for programs that attempt to send data out. In terms of function, the program requires little interaction and runs in the background. While advanced users would not likely have a problem with this, the potentially complicated permissions needed to tailor the program would be too much for beginners. Technical support and updates exist, but the program contained no visible instructions on how to use it. An extensive and complicated end-user agreement also needed to be accepted. While it does include a native installer, loading the program proved tricky and required a restart in order for it to work. After that, $29.95 buys the full version with no restrictions. Little Snitch for Mac can be tried out for free for 30 days.

I lost the mailing list archive in which they had said this as the person who contacted the dev pasted in their email exactly. Almost their words exactly which I don't quite understand.

I talked to the auther and they don't want to make little snich's check boes accessible because they clame that voice over is a danger to the mac.
