I just got a MacBook Air, and because it's my first Mac, I set up an Apple ID and account while setting up my MacBook. However, I can't sign-in to the App Store. Here's what happens:
Box that says "Sign in to download from the App Store." And I sign-in.
Another box says "This Apple ID has not yet been used with the App Store. Please review your account information."
I click on "review", a new box says "Sign in required for account creation."
So, I enter my password, and the box that says "This Apple ID has not yet been used with the App Store. Please review your account information" comes up again.
From here I encounter an endless loop.
From what I found online, setting up payment information should fix this situation, but I have entered payment information and this problem still persists.
