Cannot login to iCloud on Mac Pro after changing to two-factor authentication.
I have changed to two-factor authentication, but cannot login to iCloud on my Mac Pro (macOS Majave 10.14). After submitting my AppleID and verification code, the login process seems to hang (wheel keeps turning). I have already restarted my system. Everything seems to work fine on my iPad and iPhone.
What can I do now?
