An Apple ID is a key part of owning an Apple device and is used to access iCloud, App Store, iTunes, Apple Music, and more. It is also required to sync content between devices, use Find My, make purchases, and more.
Creating an Apple ID is free and easy, and it's the first step in setting up an Apple device if you're new to the Apple ecosystem. Here's how to create an Apple ID on a Mac.
Register through system preferences
Open System Preferences.
In the empty profile interface, tap "Login".
Click the "Create Apple ID ..." option at the bottom of the window.
Follow all prompts and fill in the required information to create an account.
You will be asked to enter your first and last name, country, date of birth, a password, and a series of security questions.
Apple ID account records will need to be verified and Apple will send a verification email. Your Apple ID will be the email you signed up with, which is worth keeping in mind.
