Procurei nos menus do iStat e notei que um processo chamado lsd
consumia 99% da minha CPU (de 400% para 4 núcleos). Procurei um pouco, mas não consegui descobrir o que era e por que está usando tanto poder de processamento. Não é o Little Snitch Daemon, pois nunca o instalei. Alguém disse que poderia ser o Launch Services Daemon, mas eu pensei que era esse processo É o Launch Services Daemon.launchd
.
Ao procurar no console, noto estas mensagens ao procurar lsd

Quanto a esta mensagem:
22/12/2015 3:44:07.469 p.m. sudo[45308]: MyUsername : TTY=ttys000 ; PWD=/private/var/db ; USER=root ; COMMAND=/bin/mkdir lsd
Eu tentei fazer um dir chamado /private/var/db/lsd
como root.
Além disso, o uso da minha CPU parece ser muito intermitente (o que nunca aconteceu antes).
Examinando /usr/libexec
, descobri lsd
e notei que ele foi criado em 17 de setembro de 2015. Por que é tão novo (além de tudo o mais nesse diretório)?
