TinyWall is another free firewall program that protects you without displaying tons of notifications and prompts like most other firewall software. https://skieyasian170.weebly.com/blog/word-count-shortcut-microsoft-word-mac.

There are a number of third-party applications/firewalls on the market such asmurus. But they basically provide the user aGUI to configure PF on macOS - of course sometimes with other useful featuresas well - and they are mostly paid application (although murus does have alite version that is free).
But if you’re comfortable with command line as I am, all GUI applications areoverkill for the problem in hand. It’s possible to configure PF to blockoutgoing traffic in several easy step and less than a few minutes!
- First, create a new anchor file named
/etc/pf.anchors/jetbrains
with thefollowing PF rule to block traffic on interfaceen0
for any traffic sent toIP multicast address230.230.230.230
:You would need sudo privillege to create file under/etc/pf.anchors

/etc/pf.conf
as shown here. - This is a detailed wiki about PF and its command line
pfctl
andpflog
etc. Good read if you’d like to see more example usages of these tools. - This is a great guide with discussion of security and privacy on macOS to abroad extent. It also touches packet filter and discusses options forthird-party firewalls (including options that may not use PF).
