AirDrop

AirDrop is a Wi-Fi ad-hoc service in Apple's OS X operating system, introduced in version Mac OS X 10.7 "Lion". Using AirDrop, users can share files with other supported Mac computers running OS X 10.7 or later without the need of a Wi-Fi network or any configuration and without the need of USB mass-storage devices. The feature is available through a special folder in Finder, and as of OS X 10.8.1 can be accessed through the menus Go > AirDrop or by pressing ⇧ Shift+⌘ Cmd+R.

AirDrop is limited to these models and newer:

• MacBook Pro (Late 2008 or newer)
  • The MacBook Pro (17-Inch Late 2008) and the white MacBook (Late 2008) do not support AirDrop.
• MacBook Air (Late 2010 or newer)
• MacBook (Late 2008 or newer)*
• iMac (Early 2009 or newer)
• Mac Mini (Mid 2010 or newer)
• Mac Pro (Early 2009 with AirPort Extreme card, or Mid 2010)

AirDrop is also available on Hackintoshes (generic PCs running Mac OS X) and which have AirDrop-supported WiFi cards, such as Broadcom's 4322/94322. Despite Apple's claimed restrictions, hackers have found that Airdrop can be enabled on any Macintosh running OS X Lion with a shell command, and will work over Ethernet as well.
