Macbook Pro iCloud Verification Failed

Hello oneadam211,

We would suggest that you start by working through these steps found at If you can't connect or sign in to iCloud - Apple Support that help with sign in issues:

If you can't remember your Apple ID or password

If you can't remember your Apple ID, check these settings and services to find it. If you've forgotten your Apple ID password, learn how to reset it. 

If you get a message that your Apple ID is locked or disabled

If you or someone else enters your password, security questions, or other account information incorrectly too many times, your Apple ID automatically locks to protect your security and you can't sign in to any Apple services. Learn how to unlock your Apple ID. 

If you can't sign in to iCloud.com

Learn what to do if you have trouble signing in to iCloud.com. 

If you're not able to sign in using cellular data only

Make sure that your iPhone, iPad, or PC has a strong Internet connection and that you've turned on cellular data on your iPhone or iPad by going to Settings > Cellular or Mobile Data. If this setting is off, you might not be able to access your Apple ID and iCloud when not connected to a Wi-Fi network. 

If you're having trouble receiving verification codes, or your verification code is rejected

Learn how to get a verification code and sign in to iCloud with two-factor authentication. If your device is running iOS 8 or OS X Yosemite or earlier, sign in using two-step verification instead.

If you see a Could Not Create Apple ID or Could Not Set Up iCloud message

If you see one of these messages, it means that you have exceeded the number of new Apple IDs you can set up with iCloud on a single device in one year. Learn what to do. 

There is additional information on that page should you need it.

Cheers.
