Restart fseventsd on a mac
if fseventsd is taking 100% or more of a CPU you can restart it by quitting it in Activity Monitor (after which it restarts automatically).
- Open Activity Monitor
-
fseventsdwill probably be visible if it's having an issue. You can also search for it, if it's not for some reason. - Double click it.
-
Click
Quitin the pop-up window.
It's usually not an issue, but when my machine has been up for a couple weeks and I've been using multiple file watchers a bunch it can freak out.
Quitting it and letting it restart itself clears things up.
