Hello Rayd8rn,
We want you to be able to use your new Mac, so let's get you past this iCloud step.
Since it has been stuck here for quite a while, we suggest using this resource to restart: How to turn your Mac on or off
Specifically, these steps: "Turn off (shut down) your Mac
The best way to shut down your Mac is to choose Shut Down from the Apple menu .
Just as your Mac follows a startup process after it turns on, it follows a shutdown process before it turns off. That process includes automatically quitting all open apps and logging out of your macOS user account.
If your Mac doesn't shut down, try Force Quit to close any apps that aren't responding. If that doesn't work, press and hold the power button until the Mac turns off."
After it restarts, make sure you are connected to a strong Wi-Fi network before you begin the iCloud sign in process.
We hope this help. Have a great day.
