Mac Basics: AirDrop helps you share items with others nearby
http://support.apple.com/kb/ht4783
When you select AirDrop, OS X looks for other Macs that are close by and also using AirDrop. If you don't see someone in the AirDrop window:
- Make sure Wi-Fi is turned on at both computers. Although you don't have to connect to a specific network, Wi-Fi needs to be turned on to transmit and receive files wirelessly.
- Make sure that the recipient has selected AirDrop in the Finder. If you don't see this option in the Finder, refer to the Additional Information section of this article to make sure the computer is compatible with AirDrop.
- Try moving the computers closer to each other. AirDrop is designed to work within a range of approximately 30 feet (9 meters). If you need to send a file to someone further away, consider using File Sharing, iCloud or email instead.
AirDrop requires that both Mac computers include Wi-Fi hardware that supports AirDrop mode. Both Mac computers need to have OS X Lion or later installed.To see if your Mac works with AirDrop, make sure you’re in the Finder by clicking the desktop (the background area of your screen), or by clicking the Finder icon in the Dock. Then, check to see if AirDrop is listed as an option in the Go menu. If you don't see AirDrop listed, your Mac doesn't support this feature.
