Q: Never-ending loop on Mac with 2-step verification
I've got a new Macbook and all is set up fine, however when I try to buy more iCloud storage, with it being a new computer it asks for my Apple ID password, and once input does the usual verification code sent to your trusted device. Both my iPad and iPhone get the request, however the screen on the Mac never changes to allow the verification code to be input. It simply says 'enter your password followed by the verification code sent to your trusted device' - when I enter the password it repeats the loop, sending a new verification code to both iPad & iPhone and the Mac again asks for my password followed by verification code but the box to put the verification code in never appears........
MacBook Pro with Retina display, OS X El Capitan (10.11.6)

Try doing exactly what the message says -- "enter your password followed by the verification code sent to your trusted device"
e.g., if your password is xyz and the verification code is 123456, enter xyz123456 into the password area.
The newer "two-step authentication" (not the older "two-step verification") requires that method of input on devices running older versions of the OS. Not sure why that would be happening in your situation but it is worth a try.
See the quote below from Two-factor authentication for Apple ID - Apple Support
If you use two-factor authentication with devices running older OS versions, you might be asked to add your six-digit verification code to the end of your password when signing in. Get your verification code from a trusted device running iOS 9 or OS X El Capitan, or have it sent to your trusted phone number. Then type your password followed by the six-digit verification code directly into the password field.
