Ho sostituito il disco rigido originale per Samsung SSD e anche la memoria aggiornata.
Ora ho installato El Capitan e voglio eseguire Apple Hardware Test.
Ho già provato 'D', Option + 'D' entrambi non hanno fatto nulla.
Ho controllato sotto "/ System / Library / CoreServices" e nessuna cartella ".diagnostics". Ho provato a copiare questa cartella su CoreServices e non sono in grado di farlo poiché il messaggio di errore non dice autorizzazione.
sudo cp -R /Volumes/AppleHardwareTest/System/Library/CoreServices/.diagnostics /System/Library/CoreServices
