Macs have a built-in way of letting you transfer files from one Mac to another using Airdrop over a wireless network connection.
According to Apple: “AirDrop lets you quickly send files, clippings, webpages, and more to anyone near you—wirelessly. AirDrop doesn’t require passwords, setup, or special settings. It makes sharing with neighbors as simple as dragging and dropping.”
I tried using Airdrop to transfer about 4 gigs of P90 workout videos from my 13-inch Macbook Pro running OS X 10.9.4 (Maverick) to my new 15-inch Macbook Pro Retina with the same operating system version. It was easy and fast.
To transfer files between 2 Macs, just open Finder on both laptops and also click “Airdrop” on both laptops. Each laptop will show the other laptop’s icon in Airdrop.
Choose the files or folders that you want to transfer, and then drag and drop them onto the Airdrop icon of the other laptop. You’ll be prompted to confirm that you want to send files to the other computer:
Then on the other computer you’ll be prompted to confirm that you want to save the files:
After you confirm both prompts, the files and/or folders that you selected will start to copy to the other machine.
The transferred files will show up in the Downloads folder of the second machine, and from there you can move them to wherever you want them to go.
