Mi problema real es que cuando se utiliza un muy largo periodo de tiempo, el comando tarda mucho tiempo en ejecutarse porque hay una abrumadora cantidad de registros de las bibliotecas del sistema, por lo que el uso de grep no sería de ayuda, prefiero el filtro de la real registro de comando.
El filtrado con messageType == 'default' elimina algunos, pero no a la mayoría. Agregar el predicado subsystem == '' hace nada para mostrar y subsystem == null produce el mensaje de error:
log: invalid predicate:
*** -[__NSSetM addObject:]: object cannot be nil
Hay una forma de filtrar la biblioteca de registros con un predicado o otro argumento?
