Create an Apple ID on Mac
An Apple ID gives you access to all Apple services, including the App Store, Apple Music, iCloud, iMessage, FaceTime, and more. It consists of an email address (for example, firstname.lastname@example.org) and a password. Apple recommends you use the same Apple ID for all Apple services. For more information about Apple ID, see the Apple ID Support website.
You can create an Apple ID on a Mac, an iOS or iPadOS device, or at the Apple ID account page.
You can create an Apple ID on your Mac using your current email address, or have an iCloud email address generated for you.
In some countries and regions, you can use a phone number instead of an email address as your Apple ID. See the Apple Support article Use your mobile phone number as your Apple ID.
On your Mac, choose Apple menu > System Settings, then click “Sign in with your Apple ID” at the top of the sidebar.
Click Don’t Have an Account? then follow the onscreen instructions.
After you create an Apple ID and sign in, you can manage your Apple ID settings on your Mac. See Manage your Apple ID settings.
To keep your purchases and access to Apple services secure, don’t share your Apple ID and password with others. To share your purchases with family members, you can set up a Family Sharing group with up to five other family members. See What is Family Sharing?
