What Is rapportd on Mac?

rapportd is the daemon behind device-to-device communication between your Apple devices: Handoff, Universal Clipboard, AirPlay and Sidecar discovery, and similar Continuity features.

No. rapportd connects to your own iPhone, iPad, Apple Watch and other Macs on the local network.

It runs as your user from /usr/libexec/rapportd.

rapportd listens on UDP 3722 and a TCP port chosen at startup, and its connections go to link-local IPv6 addresses (fe80::), meaning devices on your own network. That's why network monitors show it talking to unfamiliar-looking addresses: they're your other Apple devices. Denying it in the firewall breaks Handoff and Universal Clipboard.
