Lets your Apple devices talk to each other for Continuity features.
What it is
rapportd handles communication between your Mac and your other Apple devices for features such as Handoff, Universal Control and unlocking with Apple Watch.
It can show up in network activity or firewall prompts because it talks to nearby devices.
Should you worry?
No. It's part of macOS.
What you can do
- Turn off Continuity features you don't use in System Settings › General › AirDrop & Handoff.
