I can SignIn with Apple ID on the website, but not on my Mac, why ?
I have an Apple ID that is activated. I can sign in with the credentials on the website of Apple, BUT, when I use them to sign in on my Mac, I set them and then nothing happens. As if I'm not signed In, no pop up messages of errors or success, neither the form is redirecting somewhere else... It just displays again the same form again in order to sign in again. I can't use my email app, can't use Apple store, can't use anything ...
