MacBook Pro (16-inch, 2019) problemi all'avvio

[bugsbunny]

Buona sera il mio MacBook mi da problemi all'avvio.
lo accendo col tasto mi compare la schermata, mi chiede la password poi compare la barra orizzontale, si illumina progressivamente poi schermo nero con un sottofondo tipo "documento nel cestino". Riavvio, lo fa di nuovo... alla terza quarta volta riesco finalmente ad entrare...

Sistema operativo MacOS Catilina 10.15.4

Grazie anticipatamente per l'aiuto

Abbi pazienza... come si fa?

Niente da fare, il problema rimane.
Forse è leggermente diverso il comportamento del Mac ma rimane. Lasciato "solo" pr un ora circa si è spento lo schermo, è rimasto nero con il logo bianco e ho sentito distintamente il suono che ho descritto nel precedente messaggio.


Quando l'ho fatto ripartire mi ha segnalato che si è spento scorrettamente e mi ha dato il log da inviare a Apple.

Qualche altra idea?


Nel seguito ho incollato il log.

Sembra un problema alla scheda grafica. Esegui un reset della PRAM e poi se si ripresenta fai un BACKUP, inizializza e reinstalla macOS. In quel caso dovrai fare attenzione a quando inizializzi il disco avviando da command+R.

Mandato il Mac in assistenza. Mi hanno sostituito la scheda logica.

Ora funziona perfettamente...

Grazie a tutti

Grazie a te per il riscontro bugsbunny!
