My husband is in early stages of Alzheimer's and just bought a Macbook and was trying to set it up but got himself locked out, can't get past the initial sign in screen. He forgets things most immediately sometimes so has no idea what he did. He has tried all of his email addresses, 3, and different passwords but is now locked out. Have tried the password reset from IPhone but not getting anywhere as we never get the change password prompt. Is there a way to do a reset so he can start over? I don't use Apple products so am totally out of my element.
