Plex using 400% of my cpu power, 2018 MacBook Pro, Running Mojave

I am running version: Version 1.13.8.5395-10d48da0d

I am seeing that constantly the application is causing my laptop to overheat and my fan goes on full speed. When I close the application, heat goes back down and fans slow down to the point where I cannot hear them anymore.

That’s not necessarily unexpected behavior depending on what you’re doing at that time. If you’re e.g. watching a movie that requires transcoding, Plex will put quite some bit of work on your processor (and if that has multiple cores, Plex will happily use all of them -> hence probably the >100%). Same goes for certain background activities of Plex (e.g. if you configured it to create video thumbnails of your content).

a laptop is verry bad slow i have an i7 4790k 16 gig ram gtx 1060 pc and when 3 4 people are watching i stil have only like 35 20% cpu useage sometimes it goes lower most of the times it’s even on 15%. :slight_smile:

I understand your perspective, but I use Plex almost everyday. The time when the application causes to use so much processing power happens to be when I am actually not watching anything (just have the Plex server on in the background). I started noticing it after the latest Plex server update/MacOS Mojave update. Both happened right around the same time, so I am not sure if one or the other is causing it, or both.

I am currently testing with a 1080p clip and there are no transcoding sessions. Film is streaming perfectly fine and CPU usage for Plex Media server is hovering between 2-3%. It is bizarre.

Have you checked your Maintenance Schedule
