Apple ID not working on MacBook
My Apple ID works just fine on my iPhone XR. It always worked on my MacBook Pro as well, until recently. Suddenly it keeps making me login over and over and telling me an unknown error occurred. I tried searching the problem and did everything i could find as far as trying to fix this "unknown error" message loop wanting me to keep logging in. Nothing has worked. Restarted MacBook, Signed out of Icloud, updated macbook, removed macbook from my icloud account on my iphone and tried to re-add it after... nothing is working. HELP!
