I noticed there were a number of questions regarding 'empdaemon' on here, but none answered my specific dilemma. I noticed 'empdaemon' was appearing regularly at the top of my Activity Monitor CPU, especially when watching youtube. It also used small amounts of CPU even when I wasn't watching video of any kind. I looked into it and found out it was the result of 'Elmedia Player'. I don't even remember installing this, and couldn't find any sign of it on my system apart from some files in my library. I ran the 'uninstall elmedia player', and deleted the library files. However 'empdaemon' is still appearing in my CPU processes when I start up my mac. Via terminal I looked to see if I had any third-party kernel extensions, and indeed 'elmedia player' was listed (along with one for soundflower (something I downloaded a while back and never use)). Can someone explain how to resolve this? 1) why is it still appearing on my system, and 2) how do I remove it? Does the fact it's a third-party kernel extension mean it is restarted every time I boot up my mac? (apologies for my lack of understanding on something which is no-doubt very basic) Also, as a final question, what is the point of Elmedia Player?... when watching youtube, if I quit 'empdaemon' via Activity Monitor, it has no impact on the streaming of the video.
