Cargas de mensagens de erro opendirectoryd no log do sistema

Estou vendo esses erros nos meus arquivos de log do sistema MacOS (10.12.1) em grandes quantidades.

Alguma idéia de onde isso pode vir? Não foi possível encontrar nada útil no Google até o momento. Eles parecem persistir mesmo se todas as redes estiverem desativadas.

Este é apenas um trecho - eles são postados no log a cada poucos segundos.

Acredito que isso possa ser devido ao Dropbox. Tente desativá-lo e veja se as solicitações param.

Eu tive o mesmo problema e usei o Etrecheck para limpar alguns links quebrados e alguns adwares; funcionou como um encanto, agora o log do meu console voltou ao 'normal' e o uso da CPU também.

Você pode tentar, recomendo fazer um backup antes de excluir qualquer arquivo, mas como eu disse, o Etrecheck fez um ótimo trabalho ( http://etrecheck.com/ ).

Boa sorte.
