Data Migration
Data migration was originally part of Apple’s One to One program. This was a training program offered at Apple retail stores. Through this program that cost US$99/year you could learn more about your Mac and get assistance from an Apple retail employee. The program was shut down in 2015.
But now when you buy a new Mac in an Apple Store, an employee will migrate your data from your old computer to your new one for free. For more knowledgeable users, macOS has a built-in Migration Assistant where you can do this yourself.
Migrate your data for free, but if you just bought one of the new MacBooks, forget about doing anything with it using THAT keyboard!
