I have a Mac Mini, iPhone, Apple TV, and Apple Watch and been using them fine. Tonight I used my MacBook Air that I hadn't used in a few weeks. It told me that my AppleID or password was invalid. I retyped it a few times with no luck. It then sent me to reset it. I did that. Now all my devices repeat this same message and I'm positive I'm typing it right. The other odd thing is my iPhone seems to have access to everything it should need my iCloud ID for after it says it was invalid. Any ideas how to fix?
