Log - Default: 12, Info: 0, Debug: 0, Error: 0, Fault: 0
Activity - Create: 3, Transition: 0, Actions: 0Mon problème réel est que lorsque j'utilise un intervalle de temps très long, la commande prend beaucoup de temps à s'exécuter parce qu'il y a une quantité écrasante de journaux provenant des bibliothèques du système, donc utiliser grep ne serait pas utile, je préférerais filtrer à partir de la commande de journal réelle.
Filtrage avec messageType == 'default' en supprime certains mais pas la plupart. Ajout du prédicat subsystem == '' ne fait rien apparaître, et subsystem == null produit l'erreur :
log: invalid predicate:
*** -[__NSSetM addObject:]: object cannot be nilExiste-t-il un moyen de filtrer les journaux de la bibliothèque avec un prédicat ou un autre argument ?
