Da un paio di giorni, ho sperimentato il problema strano che OS X 10.10.3 non reagisce agli input da tastiera o mouse, eccetto i gesti multitouch come i 4-finger swipes. L'insensibilità persisterà per ~ 20 secondi (non ho ancora contato) e poi tutti i clic e le pressioni dei tasti che ho fatto durante quel periodo sembrano essere eseguiti rapidamente uno dopo l'altro, come se fossero stati memorizzati in un buffer da qualche parte e il buffer avesse poi stato lavato.
Ho associato questo problema al seguente messaggio di log nella Console
IOHIDSystem: postEvent LLEventQueue overflow.
Che ha senso in quanto si adatta ai sintomi. Tuttavia, non riesco a capire, cosa fa scattare esattamente questo comportamento.
Possiedo un MBP 9,2 con 8 GB di RAM, un SSD Samsung EVO da 120 GB come unità principale e l'unità da 500 GB di serie nell'alloggiamento ottico. Entrambi hanno > spazio libero da 30 GB. Inoltre, secondo Activity Monitor, i blocchi non coincidono con l'alta pressione della memoria.
Non ho mai avuto il problema prima dell'aggiornamento 10.10.3 recente, ma non riesco a capire se rappresenti realmente (dall'aggiornamento ho anche occasionali problemi grafici, quindi potrebbe essere che l'aggiornamento fosse bug, è impossibile dirlo) .
La domanda è: come posso diagnosticare esattamente il problema o come posso risolverlo?
EDIT : i precedenti messaggi di log sembrano insignificanti, come questo
