Hello,

I recently bout an iPhone 11 Pro Max and created apple id and used Messages app for quite some time. Two months back I got a Macbook Pro 2017 and I wanted to wire my Messages to be used on my mac. But I cannot login into messages, I always get: An error occurred during authentication. •

I tried:

Logging in and logging out of my iPhone and my Mac and I got this on my iPhone:

• Resetting NVRAM (not sure if that was a successful operation)

• Adding more "contactable at" addresses (iPhone seems to instantly react and ask me to add the email)

If you can't sign in to your iMessage account or FaceTime on ...
