Updates to Bluetooth wireless networking, combined with new software in Apple's iOS 7 and OS X Yosemite, have changed how you transfer files between iPhones, other iOS devices and Macs. Using Apple's AirDrop technology, you can transfer files between a Mac and an iPhone using a combination of Bluetooth and Wi-Fi without the fuss of Bluetooth pairing.
On the iPhone
From the iPhone's Home screen, slide up to reveal the Control Center.
Tap the Wi-Fi and Bluetooth symbols to turn these network services on, if necessary. Tap AirDrop and change its setting to Everyone; this ensures that the Mac will pick up the iPhone's signal.
On the Mac:
Click the Finder icon in the Dock.
Click the File menu, and then click New Finder Window. Move the second Finder window so you can see both windows.
Click the AirDrop shortcut in the second Finder window to see your iPhone and any other nearby OS X or iOS devices.
Locate the files you want to transfer in the first Finder window.
Click the files or folders to copy in the first Finder window. Drag them to the iPhone AirDrop user icon in the second Finder window to transfer the files to the iPhone.
