Apple Mac mini (Late 2014) - Manual (Page 5)

Let’s get started
Press the power button to start up your Mac mini, and Setup Assistant
guides you through a few simple steps to get you up and running. It walks
you through connecting to your Wi-Fi network and creating a user account.
And it can even transfer your documents, email, photos, music, and movies
to your new Mac from another Mac or PC.
Sign in with your Apple ID in Setup Assistant. This sets up your account in
the Mac App Store and the iTunes Store, and in apps like Messages and
FaceTime, so they’re ready the first time you open them. It also sets up
iCloud, so apps such as Mail, Contacts, Calendar, and Safari have all your
latest information. If you don’t have an Apple ID, create one in Setup
Assistant.
