I installed Big Sur the other day, I've had some major issues since installing, but I've managed to sort them out one by one, including the fact that it removed my admin account. Anyway, when I run a video in safari, be it a news Chanel or any other site, after a few minutes of watching the video, the CPU usage, jumps to 105% and the fan goes nuts. Then, after around 10-15 mins, the video will crash. I'm starting to wish I hadn't installed it! I'm running it on a 2019 MacBook Pro 15". I've tried clearing the cache and internet history, this works for a short while before the problem reemerges. What could be causing this issue?
Big Sur - High CPU usage running video
Big Sur is absolutely terrible. I hope Apple does something about it. Catalina was way better. Don’t change something if all ready great. Thank you.
