Sorry guys, i inserted device in recovery mode, than connected to wifi and after download - appeared this message on the screen. The same dump you gave me. How i can unlock this password? sorry for double message
after flash the bios please then turn it on and immediately hold down these four keys together: Option, Command, P, and R. Keep holding the keys for about 20 seconds, during which your Mac might appear to restart. (If you have a Mac that plays a startup sound when you turn it on, you can release the keys after the second startup sound.)
