How to Transfer Video to the MacBook Air (9 Steps)

Attach a USB hard drive to a secondary computer and copy any video files you wish to transfer to your MacBook Air. On either an OS X or Windows-based computer, highlight the files you want to transfer and use your mouse to drag them onto the external hard drive.
Eject the hard drive and connect it to your MacBook Air. Use the hard drive's USB cable to connect to a USB 2.0 port on the side of the MacBook Air.
Wait several seconds for the hard drive to appear within the MacBook Air's Finder. Select the hard drive's entry under 'Devices' --- on the left side of the Finder window --- to bring up the hard drive's contents.
Select the video files saved on the USB hard drive. Drag them with your mouse from the USB hard drive onto your MacBook's desktop. This will cause a transfer progress bar to appear. Once the bar is finished, your video files will be transferred onto the MacBook Air.
