Here are a few simple steps to help you get up and running.
First, press the power button to start up your iMac Pro.
Your rechargeable Magic Mouse 2 and Magic Keyboard with Numeric Keypad are
already paired with your iMac Pro. If you purchased a Magic Trackpad 2 with your
iMac Pro, it will also be paired. To begin using these devices, simply turn the on/off
switch to on (green will be visible).
Next, Setup Assistant will help you connect to your Wi-Fi network, create a user
account, and migrate your documents, photos, and music from a Mac or PC. It can
also help you create a new Apple ID or sign in with your existing Apple ID, which
sets up your account in the App Store, the iTunes Store, Messages, and FaceTime.
Setup Assistant also configures iCloud, so apps such as Mail, Contacts, Calendar,
and Safari will have your latest information.
