Cannot Login to iCloud - MacBook Air
I have tried several times (also after restart and shut down) to log in to iCloud from system preferences, but I am unable to log in (while I am still connected on iPhone, iPad, and Safari). When I submit (the correct) email and password combination, the system just returns to the sign-in window with no error message.
Any advice?
MacBook Air, macOS High Sierra (10.13.1)
