  • Power on your Mac and launch Terminal.

  • Copy and paste the following command (or type it exactly) into Terminal:

  • sudo nvram AutoBoot=%00

  • Press [return]. If prompted, enter your administrator password and press [return] again. Note: Your return key may also be labeled ⏎ or "enter."

Prima di iniziare questa procedura, devi disabilitare la funzionalità Auto Boot del tuo Mac. Il Boot automatico è già attivo sul tuo Mac non appena apri il coperchio e quindi può essere attivato accidentalmente in fase di smontaggio. Usa questa guida oppure segui le istruzioni abbreviate qui sotto per disabilitare l'Auto Boot.

Accendi il tuo Mac e lancia Terminal.

Copia e incolla seguente comando (oppure riportalo esattamente) in Terminal:

sudo nvram AutoBoot=%00

Premi [return]. Se richiesta, inserisci la tua password di amministratore e premi di nuovo [return]. Nota: il tuo tasto return può essere etichettato anche come ⏎ o "enter."

Ora puoi spegnere in sicurezza il tuo Mac e aprire il case inferiore senza rischiare di accenderlo inavvertitamente.

Quando la riparazione è terminata e il tuo Mac è stato rimontato con successo, abilita di nuovo l'Auto Boot con il comando seguente:

sudo nvram AutoBoot=%03
