Non ho mai avuto un singolo panico del kernel sull'iMac retina da 21 "(Fine 2015) da quando l'ho preso all'inizio di quest'anno.
Questa mattina, quando ho iniziato a usarlo (di solito non è spento perché ci sono compiti che devono essere eseguiti durante la notte) c'erano due aggiornamenti pronti per l'installazione: 1password e iTunes. Una volta eseguita l'installazione (non ho idea se siano collegati in qualche modo) l'iMac ha avviato il kernel nel panico abbastanza regolarmente senza un accenno a una possibile causa.
Questo è l'ultimo rapporto:

Ho iniziato a rimuovere 1password e disabilitare l'helper di itunes. Non ha aiutato Ho disabilitato ogni tipo di cose all'avvio: niente. Ho creato un nuovo utente: boom. Ho controllato il disco con l'Utility Disco: nessun errore trovato. Ho avviato il programma di test dell'hardware e non ho riscontrato problemi.
Ha iniziato a diventare pescoso una volta che si è schiantato in modalità provvisoria e - successivamente - in esecuzione su una chiavetta USB appena creata (su un altro Mac, come si fa in questo caso) con El Capitan 10.11.5.
Ho staccato ogni tipo di dispositivo, rimosso il monitor esterno, ho tirato fuori il cavo lan, ho persino cambiato il cavo di alimentazione: ancora in crash.
Che cosa fare ora?
