Little Snitch

See and block every connection your Mac apps make

Mac$59 once

The verdict

The firewall built into macOS covers incoming connections, and Little Snitch covers the other direction, alerting you each time an app tries to reach the internet so you can allow or block it. Its Network Monitor maps every connection and how much data went where, and daily updated blocklists stop trackers. You answer a prompt for each new connection until your rules are built, and $59 is a lot if you only want trackers gone.
