Tengo un MacBook Pro de mediados de 2012 y lo actualicé a OS X Yosemite hace unas semanas. Varias veces desde entonces, la GPU se ha bloqueado y aún puedo mover el cursor del mouse por la pantalla y escuchar el audio, pero todo lo demás en la pantalla no responde. Solo logré remediar esto reiniciando la máquina.
¿Hay alguna manera de evitar que esto suceda?
