Sto riscontrando un problema con il mio Retina iMac che genera regolarmente un errore "È stato rilevato un problema grafico". L'iMac ha l'opzione AMD Radeon R9 M295X.
Alla fine della giornata me ne vado e lo lascio ai suoi dispositivi. Io non lo spengo o lo metto esplicitamente a dormire. Al mattino mi aspetto di svegliarlo e andare avanti, ma spesso deve essere acceso e avviato.
Quando si riavvia, viene visualizzata una finestra di dialogo con il messaggio di errore "È stato rilevato un problema grafico".
Nel log della console vedo una serie di messaggi "Provare a riavviare GPU". Di seguito è riportato l'ultimo di questi messaggi e tutte le voci del registro precedenti.
Qualcuno sa come risolvere il problema?
