What is sharingd on Mac?
sharingd runs AirDrop, Handoff, Instant Hotspot and the shared computers in the Finder. AirDrop transfers can show under it.
Where you see it
sharingdis in the list in Activity Monitor › Network, innettopor in Kilobat.- A firewall or network monitor asks if
sharingdcan connect. - Traffic appears when you use AirDrop.
What it is
The man page says that the Finder uses sharingd for AirDrop, Handoff, Instant Hotspot discovery, shared computers and Remote Disc.
It first appeared in Mac OS X 10.9. The program is /usr/libexec/sharingd.
Why it uses the network
- AirDrop. AirDrop sends files directly between devices, over a peer-to-peer Wi-Fi link.
- Discovery. It finds nearby devices for AirDrop, Handoff and Instant Hotspot.
- Shared computers. The Finder sidebar lists other computers on the network.
Is it normal?
Yes. Traffic during an AirDrop transfer is usual. It does not use your internet connection.
