Macbook still not recognising Apple ID password
My password is being recognised everywhere else but not on my Macbook (Settings). Have tried advice given on previous post https://discussions.apple.com/thread/8315669 but no verification code is sent. Nothing happens at all. I am not changing my password AGAIN (this doesn't work either)!
Any assistance from Apple would be greatly appreciated.
MacBook Air 13", macOS 10.13
