What Firewall settings needs to be enabled for Airdrop?

Which option in the built-in firewall in System Preferences needs to be enabled to allow AirDrop to receive files on a Mac?

The Mac can currently see iPhone's and other devices in Airdrop, but does not show on the iPhone as a target for Airdrop.


Solution 1:

  1. Open System Preferences -> Security & Privacy -> Firewall

  2. Select Firewall Options

  3. In the list set "sharingd" to "Allow Incoming Connections"

Alternatively, tick "Automatically allow built-in software to receive incoming connections"
