The first time your iMac starts up, Setup Assistant walks you through the simple steps needed to start using your new Mac. You can respond to all the prompts, or skip some steps and choose to complete them later. For example, it might make sense to set up Screen Time—which you can set for different users—after initial setup.
Setup Assistant guides you through the following:
Set your country or region: This sets the language and time zone for your Mac.
Accessibility options: View accessibility options for Vision, Motor, Hearing, Cognitive abilities, or click Not Now. To learn more, see in the menu bar, you can add it. Open Sign in with the same Apple ID to use any Apple service, on any device—whether it’s your computer, iOS device, iPadOS device, or Apple Watch. See Siri on your Mac.
Set up Touch ID: If your keyboard supports it, you can add a fingerprint to Touch ID when you set up your 24-inch iMac. To set up Touch ID later, or to add additional fingerprints, open System Preferences, then click Touch ID. To add a fingerprint, click Mac tips for Windows switchers.
