Tip : Enable Lion's Airdrop on unsupported Wifi cards / USB dongles
I just have to sharethis.
Lion includes a new technology called "AirDrop" which is Apple's name for adhoc wifi data exchange.
When two machines that both run Lion are visible to each other ( nearby , "ad hoc networked" ) , Users can launch Finder, go to "Airdrop" in the sidebar and will see each others Machine. You then can simply drag and drop all sort of documents onto the icon of the mac next yours without having to think about setting up a network or dig deeply into Networking details.
This new technology is not enabled for all wifi "Airport" cards and never for 3rd party devices ( usb dongles , pci cards etc that have OS X drivers available )
Now here is how to enable Airdrop on EVERY wifi device, regardless of vendor,make or type. The device needs only to work in Lion of course.
fire up the terminal.app and write :
defaults write com.apple.NetworkBrowser BrowseAllInterfaces 1
then hit enter ,
now restart the Finder to have the new sidebar item visible ( a animated radar screen ) with this command :
killall Finder && open /System/Library/CoreServices/Finder.app
Et voila !
