It keeps asking my apple ID and password,but everytime I enter it it says that my apple ID has not yet been used in the iTunes store and I need to review my account information

I didn't need to save a payment method. The issue was my vpn, which was discussed on a different forum in the community. Turning off the VPN app and restarting the computer took the sign in process for the App Store out of the endless loop.

When you get that message on your screen, tap Review -> review your account information.

Try to download a free app at the Mac App Store.

Log in at appleid.apple.com and make sure you have payment information stored there.

I do not want to save payment information to my Apple ID account.

You may need to have a payment method on file, even if the app you want to download is free. Check which payment method you have on file and make sure it hasn't expired, been declined or failed.

I'm having the same issue with my MacBook Pro. I'm trying to update the apps that came with my computer, such as keynote, and I get the message that I need to review my account information. When I tap Review ->Review your account, I'm asked to sign in again and then I'm once again informed that I need to review my account.

I signed into my Apple ID on appleid.apple.com and confirmed that I'm using the correct ID email and I updated my password.

I've tried downloading a free app and got the same message about reviewing my account.

I do not want to save payment information to my Apple ID account.

I have updated these apps since I got the computer, because of this issue.
