I understand from my findings on the topic that sharedfilelistd is an "agent that is used by applications to read/modify recent documents/servers/hosts" and distnoted a "distributed notification services".

What I don't understand is why those two process very frequently start using between 130 and 200% of CPU (Monitor).

I tried various combinations of apps loaded or not that would be causing the problem, but I was unable to discern a pattern.

I can't tie this issue with any noticeable event (update, install, config tweak, ...).

Any idea ? (while I continue looking into possible causes)

  • To rule out if these have legitimate work to do, what happens if you disconnect all network connections and restart the Mac. These daemons should process all remaining work and then be mostly idle 20 minutes after you log in. – bmike May 6 '18 at 15:27

I had the same problem with sharedfilelistd consistently taking over 100% of my CPU. I don't have file sharing enabled.

I opened up Terminal and found the processes with pgrep -lf sharedfilelistd, noticing two of them running; that might have indicated a problem. I killed both with sudo pkill sharedfilelistd and they terminated and one restarted, presumably via launchd.

After the single process returned, it took between 30-75% of my CPU, perhaps averaging 50%, and my machine is back to normal. There might be some impact to some service I'm not aware of or do not use, but this worked for me.


I also had this problem, which I solved when I emptied the Trash

I shut down the file sharing and remote combo in the preferences and the two processes automatically exited

  • I've turned off all sharing in system prefs and still very high cpu. Will restart and see what happens. – David Clarke Jun 28 '18 at 23:59
  • I see no effect turning off all sharing either. – Trejkaz Sep 14 '18 at 5:43
