AirDrop is an ad-hoc service in Apple Inc.'s OS X and iOS operating systems, introduced in Mac OS X Lion (OS X 10.7) and iOS 7[1] that enables users to transfer files to another supported Mac computer and iOS mobile device without using email or a mass storage device.[1] OS X and iOS use different AirDrop protocols and are currently not interoperable.[2] AirDrop in OS X operates over Wi-Fi, whereas the iOS implementation utilizes both Wi-Fi and Bluetooth. Once OS X 10.10 Yosemite and iOS 8 are released however, users will be able to AirDrop between their computer and mobile device.

There is currently no size restriction to how large a file can be sent over AirDrop, Apple users have reported movie files over 10GB being sent over AirDrop without any problems. A restriction on AirDrop is that the two computers have to be within 10 meters of each other for AirDrop to recognize the other party. To date only a small number of applications implement the AirDrop facility.

Routine[edit]

AirDrop on an iPhone

On devices using OS X 10.7, AirDrop is available through a special folder in Finder, and as of OS X 10.8.1 can be accessed through the menu option Go > AirDrop or by pressing Shift+ Cmd+R. For the feature to work, Wi-Fi must be turned on in order for AirDrop to recognize the other device. The other device must also use the same AirDrop folder in Finder to be able to transfer files. Furthermore, files are not automatically accepted; the receiving user must be willing to accept the transfer.[3] This is done to increase security and prevent others from tracking who is nearby.

On iOS 7 and later, AirDrop can be set only through the Control Center introduced in iOS 7. It is located just below the quick toggles. Both Wi-Fi and Bluetooth must be activated for AirDrop to work. There are also a variety of options to increase the security of AirDrop, on activation, including:

  • Turn off device Discovery,
  • Allow Contacts only to be able to discover the device,
  • Allow everyone to be able to see the device.

Sharing on iOS is different from versions 10.7 to 10.9. Starting with OS X 10.10 Yosemite, the old version of AirDrop for mac has been replaced with the one for iOS. However, a legacy mode will exist in Yosemite for compatibility with Mavericks and prior versions. On supporting versions of iOS, if an application implements AirDrop, it is available through the share button. AirDrop is subject to a number of other restrictions, such as inability to share music from an iPod app. On supporting versions of OS X, any file or folder can be dragged to send.

In both instances, other devices appear as floating bubbles in Finder, which will usually display the other device's computer name and image. The design of AirDrop is similar to a radar display; however, devices appear randomly on the AirDrop page and there is no correlation to their physical location.

System limitations[edit]

AirDrop is not officially supported on older devices (iPhone 4S and earlier) because of hardware limitations,[4] and can be used only on these models, or newer ones:

Running iOS 7 or later:[3]

AirDrop can be enabled unofficially on iPad (3rd generation). Although not supported by default, AirDrop can be enabled by jailbreaking the device and installing "AirDrop Enabler 7.0+" from cydia. This procedure is not supported by Apple.[5]

Running Mac OS X Lion (10.7) or later:

AirDrop is also available on Hackintoshes (generic PCs running OS X) that have AirDrop-supported Wi-Fi cards, such as Broadcom's 4322/94322. Despite Apple's legal restrictions, developers have found that AirDrop can be enabled on any Macintosh running OS X Lion with a shell command,[6] and will work over Ethernet as well. In order to get AirDrop to work, both Macs have to use the same network interface.
