How to Enable AirDrop on Unsupported Systems

One of the more interesting features of MacOS X 10.7 Lion is the ad-hoc, wireless, peer to peer networking feature called AirDrop.  Unfortunately, this is only supported on the very latest hardware.  It turns out that you can easily enable AirDrop for many older Lion systems with a simple visit to the Terminal.

At the commend line, you need to enter:


defaults write com.apple.NetworkBrowser BrowseAllInterfaces 1


Then, restart the Finder with the following:


killall Finder


Open a new finder window and you should now see AirDrop listed on the left-hand side under favorites.
