Airdrop has always had the potential to be great, but by limiting it to like OSes, we’ve never really used it much. That might change in Yosemite. Apple has finally allowed iOS and OS X to communicate over Airport, so we can instantly and easily share notes, photos and whatever else needs to get from our MacBooks to our iPhones. Just click on the option in the sidebar of the Finder, wait until you see the name of your iOS device, and drop whatever you want to send on the icon. (MacLife)
