Occasionally my macbook get's incredibly hot and the fans speed up despite me not doing anything particularly intensive. Today, after shutting down every application that was running it kept getting hotter and louder so I looked into what was causing it (while I have to use task manager on pc a lot I'd never come across Activity Monitor until today). I've included a screenshot but I'm seeing Spotify Helper (Renderer) running at over 100% CPU. Questionable maths aside is there a reason this is happening? Spotify itself is closed. Ending the process saw temps drop in a few seconds and it's was back to being silent within 20 or so seconds, so clearly this is the culprit.
