If you have a relatively new Mac computer running either Lion or Mountain Lion versions of OSX, then you probably also have Air Drop. This is a new feature in Finder that will allow you to quickly and easily move files from one nearby computer to another. What’s different about Air Drop is you don’t have to have a Wi-Fi connection to do it.
To see if you have Air Drop, open your Finder app and look in the app’s sidebar. You should see the Air Drop item towards the top of the list. Click on it and you’ll see an icon representing your computer appear in the main pane. When other Macs nearby also have Air Drop active, you’ll see icons for those computers too – like you see in this example. When you do, you’re ready to start Air Dropping files.
The easiest way to do this is to select the files you want to copy, right-click on them and choose Share > Air Drop. A window similar to this one appears on the screen asking that you select the destination by clicking on the icon for that computer, then click the Send button.
The receiving computer must accept the files before they will be transferred. A screen similar to this one appears on that computer giving that user the opportunity to accept or decline the file(s).
Once accepted, the files are transferred to that user’s Downloads folder.
To shut down Air Drop on your computer, just choose a Finder item other than Air Drop.
In Mac families like ours, this is the easiest way to share files between computers. It can also be quite useful in a conference situation where Wi-Fi connectivity is limited. Take a minute to see what Air Drop can do for you. I think you’ll be pleasantly surprised.
