AirDrop is one of the amazing features in Mac OS X Lion. With AirDrop you can easily send files and folders wirelessly without setting a Wi-Fi Network.
To send files, Select ‘AirDrop‘ from ‘Go‘ Menu. Your Mac will automatically detect any AirDrop users within 30 Feet. Just drag and drop files on any listed name.
When user accepts the request, file will be transferred in encrypted format to downloads folders.
Note: If AirDrop isn’t listed under ‘Go’ Menu, it means that this feature is not supported in your Mac.
