Radio Silence Prevents Mac Applications From Calling Home, You Can Now See Traffic in Real Time
Mac: We were big fans of Radio Silence when it launched a few years ago because it was one of the easiest and cheapest ways to spy on Mac apps secretly calling home. A recent update makes Radio Silence easier to use and it now shows you traffic in real time.
As with the original version of Radio Silence, you can simply select from a list of apps and set up blocking for them so that they cannot transmit data back to the base ship. This update adds a new monitor mode that shows you not only which apps are currently sending data, but also where it is going. This can help you keep an eye on apps that may not even be transferring data. You can try a trial version of Radio Silence before deciding if you want to shell out $ 9 for the full version.
