Max book pro requires four digit code to login
my friends mac book pro won't let him login.
instead of asking him for a password, it asks for a four digit code.
theres a ”apple.help@gmx.com” link below the code entry form to contact.
is this ransom ware?
he tried booting using cmd+R while powering up, but an image of a padlock
and the four digit code entry form appeared instead of a login screen.
what should he do?
thanks!
