Ho un MacBook Air, all'inizio del 2015, con MacOS Mojave in esecuzione. Nelle ultime 2 settimane, è stato arrestato in modo imprevisto e riavviato per periodi di tempo diversi.
Dopo aver controllato i log di shutdown, ho trovato che il codice di shutdown era -128 ; controllando varie fonti su Internet, ho scoperto che si trattava di un codice "catch all hardware issues". Molte fonti hanno dimostrato che ciò potrebbe essere causato dal surriscaldamento del computer, dalla RAM o dalla batteria malfunzionanti.
Il mio computer non si surriscalda quando si spegne / si riavvia; la batteria sembra funzionare bene e non ho installato alcuna RAM di terze parti. Informazioni di sistema sembra mostrare sia le schede RAM che lo stato "OK".
Ho provato a fare quanto segue
- Ripristino di SMC.
- Ripristino della NVRAM.
- Avvio in modalità provvisoria.
inutilmente.
Il problema è iniziato all'improvviso quando eseguivo macOS High Sierra (l'ho eseguito per un po 'di tempo e il sistema operativo era stabile). Ho appena installato macOS Mojave (cancellando tutti i dati precedenti), quindi sono abbastanza sicuro che questo non sia stato causato da malware di qualche tipo. Apple non mostra alcun messaggio come "Il computer si spegne a causa di un problema" e i registri non mostrano alcun Kernel Panics.
Ho eseguito la diagnostica hardware, ma non ha mostrato alcun problema. Ho anche eseguito First Aid sotto Utility Disco per sicurezza.
Un'altra cosa che ho notato, che non sono sicuro che ci fosse prima, è che durante l'avvio, con la barra di caricamento verso la metà, lo schermo del computer diventa improvvisamente nero per un secondo o due, e poi ritorna per continuare da dove era stato interrotto. Non sono sicuro se questo è collegato.
Per essere chiari, il periodo di tempo tra i riavvii e gli arresti è molto vario; una volta, è stato riavviato tre volte durante l'uso entro un minuto o due. Solitamente, si spegne solo nel sonno (non causato da autopoweroff , sempre lo stesso codice di spegnimento), dopo ore di mancato utilizzo.
Ho notato che il log di shutdown è esattamente il momento in cui lo avvio. Non so davvero cosa farmene.
Ecco alcuni log del secondo prima dell'arresto del computer con il codice -128 (e anche l'ora in cui stavo tentando di estrarlo dal sonno):

C'è qualcos'altro che posso provare prima di consegnare il MacBook a un professionista? Lo uso da circa due anni e non è coperto da garanzia.
