AirDrop is a feature in iOS and macOS that lets you wirelessly share files between nearby Apple devices. AirDrop uses Bluetooth low energy to discover and negotiate connections and point-to-point Wi-Fi to transfer information. You can use AirDrop to share photos, videos, websites, and locations between devices that are up to about 30 feet apart. AirDrop was introduced in Mac OS X Lion (Mac OS X 10.7) and iOS 7. It requires iOS 7, iPadOS 13, or OS X 10.10, or later. Both Wi-Fi and Bluetooth must be turned on to use AirDrop. AirDrop is generally considered secure as long as users take precautions such as setting it to "Contacts Only" or "Receiving Off." Apple has implemented several security features to ensure that data transfers are private and secure.
