J'ai regardé dans iStat Menus et j'ai remarqué qu'un processus nommé lsd
consommait 99% de mon CPU (sur 400% pour 4 cœurs). J'ai cherché un peu, mais je n'ai pas pu trouver ce que c'était, et pourquoi cela utilisait autant de puissance de traitement. Ce n'est pas Little Snitch Daemon, car je ne l'ai jamais installé. Quelqu'un d'autre a dit que ça pouvait être Launch Services Daemon, mais je pensais que ce processus était C'est Launch Services Daemon.launchd
.
En regardant dans la console, je remarque ces messages lors de la recherche de lsd

Quant à ce message :
22/12/2015 3:44:07.469 p.m. sudo[45308]: MyUsername : TTY=ttys000 ; PWD=/private/var/db ; USER=root ; COMMAND=/bin/mkdir lsd
J'ai essayé de créer un répertoire appelé /private/var/db/lsd
en tant que racine.
De plus, l'utilisation de mon processeur semble être très intermittente (ce qui n'était jamais le cas auparavant).
Regarder dans /usr/libexec
J'ai trouvé lsd
et j'ai remarqué qu'il a été créé le 17 septembre 2015. Pourquoi est-il si récent (comme tout ce qui se trouve dans ce répertoire) ?
