MacOS is famous for the fact that out of the box the user gets a set of necessary software, which covers most of the needs. What is missing is a utility for monitoring network connections. This is where the Little Snitch program comes in handy .
What a beast
After installing the utility, every other program will access the network with this window:
We will see the application that wants to connect to the network, the IP address and the port on which the connection is made. You can immediately set a basic rule for this program. Either allow connection to a specific address, either by the selected port, or by a combination of the first and second.
You can even give the program full access for any network activity or one-time permission to connect.
So after a few hours of work at the computer a full set of rules and exceptions will be formed for all the main programs.
You will see which utilities crawl into the network, find out the connection addresses and the frequency of network requests.
Why do you need it
It is clear that no one will limit the browser, mailer and messengers, but it will be very useful to see other processes and programs that pull traffic.
Sometimes this is the only way to prevent intrusive updates of heavy utilities that clog the entire channel when downloading an update. It turns out to completely ban access to the network for offline applications, which usually send statistics to the developer.
Having configured several profiles, you can disable cloud client synchronization, silence instant messengers or mailer with one touch. And you will clearly see how many processes in macOS regularly consume traffic, taking up a communication channel and discharging a laptop battery.
Fans of statistics will have at their disposal a powerful tool for analyzing the consumed and transmitted traffic. You can monitor network activity directly from the system menu bar.
Profit from Little Snitch will see any user, whether he uses the basic system utilities or has an extensive set of specialized software.
