Depuis quelques jours, je rencontre un problème étrange : OS X 10.10.3 ne réagit pas aux entrées du clavier ou de la souris, à l'exception des gestes multitouch comme les balayages à 4 doigts. Cette absence de réaction persiste pendant environ 20 secondes (je n'ai pas encore compté), puis tous les clics et appuis sur les touches que j'ai effectués pendant ce temps semblent être exécutés rapidement les uns après les autres, comme s'ils avaient été mis en mémoire tampon quelque part et que celle-ci avait été vidée.
J'ai associé ce problème au message de journal suivant dans la console
IOHIDSystem: postEvent LLEventQueue overflow.Ce qui est logique puisque ça correspond aux symptômes. Cependant, je n'arrive pas à comprendre ce qui déclenche exactement ce comportement.
J'ai un MBP 9,2 avec 8 Go de RAM, un SSD Samsung EVO de 120 Go comme disque principal et un disque de 500 Go dans la baie optique. Les deux ont plus de 30 Go d'espace libre. De plus, selon Activity Monitor, les gels ne coïncident pas avec une pression mémoire élevée.
Je n'ai jamais eu ce problème avant la récente mise à jour 10.10.3, mais je ne peux pas dire si c'est vraiment lié (depuis la mise à jour, j'ai aussi des problèmes graphiques occasionnels, donc il se peut que la mise à jour ait été boguée, c'est impossible à dire).
La question est de savoir comment diagnostiquer exactement le problème ou comment le réparer.
EDIT : Les messages de journal précédents semblent banals, comme ceci
