AirDrop is a feature in Mac OSX Lion for transferring files between two Macs, great feature my my wife’s Mac is on the list of Macs that do not support AirDrop. Yesterday while working on an unrelated issue, I discovered that the Deeper tool has an option to activate AirDrop on any Mac running Lion or higher. So I gave it a try, and sure enough my wife’s plastic MacBook was able to see my own Mac via AirDrop. My Mac however was not able to see my wife’s Mac. As it was after midnight I didn’t spend any time figuring out why.
This can also be enabled via the command line, so installing an extra tool isn’t required:
