rapportd (Rapport Daemon (Device Discovery)) is a safe macOS network process. rapportd is the macOS daemon that handles local device discovery and communication for features like Universal Clipboard, Handoff, AirPlay, and Sidecar. It uses Bluetooth Low Energy (BLE) and local Wi-Fi networking to discover nearby Apple devices signed into the same Apple Account, then establishes encrypted peer-to-peer connections for seamless data transfer between them. rapportd scanning for and connecting to nearby Apple devices is its normal function. Be concerned if rapportd is flagged by your firewall as attempting connections to non-local IP addresses — it should only communicate on local network and via Bluetooth. Unexpected remote connections would be abnormal.
Rapport Daemon (Device Discovery)
rapportd is the macOS daemon that handles local device discovery and communication for features like Universal Clipboard, Handoff, AirPlay, and Sidecar. It uses Bluetooth Low Energy (BLE) and local Wi-Fi networking to discover nearby Apple devices signed into the same Apple Account, then establishes encrypted peer-to-peer connections for seamless data transfer between them.
High CPU when many nearby Apple devices are discoverable
Network port warnings from firewalls about rapportd listening for connections
Handoff or Universal Clipboard not working between devices
Excessive Bluetooth activity draining battery on MacBooks
Go to System Settings > General > AirDrop & Handoff and ensure 'Allow Handoff between this Mac and your iCloud devices' is enabled. Both devices must be signed into the same Apple Account with Bluetooth and Wi-Fi enabled.
If you don't use Handoff, Universal Clipboard, or AirPlay Receiver, disable them in System Settings to reduce rapportd's activity. This is especially useful in environments with many Apple devices (offices, classrooms).
If you use the macOS firewall or a third-party firewall and see rapportd connection prompts, allow incoming connections for rapportd. It needs to accept connections from nearby devices for Handoff and AirPlay to work.
Click the Bluetooth icon in the menu bar and toggle it off, wait 10 seconds, then re-enable it. This forces rapportd to rediscover nearby devices and often resolves Handoff or device discovery issues.

CoreLock monitors rapportd's network connections to ensure they stay within expected local-network and Bluetooth bounds. It alerts you if rapportd or related device discovery services attempt unusual network communication that doesn't match normal Apple Continuity behavior.

rapportd is the daemon that enables Apple's Continuity features — Handoff, Universal Clipboard, AirPlay, and Sidecar. It discovers nearby Apple devices using Bluetooth Low Energy and establishes secure connections over local Wi-Fi for seamless data sharing between your Mac, iPhone, iPad, and Apple Watch.
rapportd listens for incoming connections from your other Apple devices to enable features like AirPlay Receiver and Handoff. This is normal behavior. It only accepts connections from devices signed into your Apple Account and encrypts all communication. Firewall prompts about rapportd are safe to allow.
Yes. rapportd is a legitimate Apple system process that handles device-to-device communication for Apple's Continuity features. All connections are encrypted and authenticated using your Apple Account credentials. It is code-signed by Apple and protected by System Integrity Protection.
