  • Sequoia: High CPU Use

    From RJH@21:1/5 to All on Sat Oct 5 22:24:35 2024
    The fans on my iMac (Intel 2020) have started kicking in since I updated the
    OS to Sequoia 15.0.1. Hardly ever heard them before.

    Two processes are constantly using 85/70% respectively of the 400% CPU - WallpaperVideoExtension and VTDecoderXPCService. Wallpaper is a static image and I don't have any screensavers etc. The CPU use of these processes remains constant, whichever apps are running.

    Any idea what's going on?!

    Hello Rob

    Sorry to learn of your dilema. May I suggest that you start your
    computer in Safe Boot Mode and then restart normally.

    This is the procedure:- https://support.apple.com/en-gb/guide/mac-help/mh21245/mac

    I hope it helps.

    Good luck! 🙂

    The procedure doesn't always work first time!

    Do make sure you see "Safe Boot" in red in the top right hand corner of
    your screen. https://i.ibb.co/n8hXvYT/IMG-0169.jpg
