Se il display del Retina MacBook Pro 2012 si è addormentato quando il computer passa dalla scheda grafica discreta Nvidia a quella integrata Intel, WindowServer si blocca. Sono in grado di spostare il cursore e persino controllare le applicazioni (ad esempio, annullare la pausa di iTunes) facendo clic alla cieca, ma l'immagine sullo schermo non verrà aggiornata.
Un modo sicuro per riprodurlo è quello di connettersi al computer tramite VNC causando che il computer passi alla grafica discreta. Quindi chiudo il client VNC sul mio telefono e utilizzo un angolo caldo per mettere il display in stop. Ogni volta che il server VNC realizza il client disconnesso, torna alla grafica integrata, attivando il bug. Tuttavia, questo non è esclusivo di VNC, poiché posso attivare questo bug con qualsiasi applicazione che utilizza la grafica discreta.

Punti di interesse: 13:18:53, mi collego tramite VNC. 13:19:14, il computer tenta di passare alla grafica Intel e ottiene molti errori. 13:19:38, uccido loginscreen tramite SSH per riavviare WindowServer.
Questa è un'installazione pulita 10.9.2 eseguita ieri utilizzando la partizione di ripristino. Il giorno prima ho avuto un 10.9 di installazione che ho aggiornato da 10.8 e 10.7 che non ha avuto questo problema, quindi non penso che sia un problema hardware. Non ho installato estensioni del kernel di terze parti.
