After instaling new macOS on my MacBook Pro it continuously heats up to 75C while doing nothing. I resterted my mac couple times with no effect, and i checked if there is no any app running in background. Is anyone got same problem after that update?

After every major upgrade there are processes that occur in the background such as new indexes and databases for such things as Photos or Search. These take time and the system needs to be up and running to resolve it. Try setting system NOT to log out or shut down for a day or so and you should see improvement.

Yes! I'm having the same issue. Ever since upgrading to BIG SUR my fans are almost always blowing very heavily and loudly, even when I'm barely doing anything intense. I have a 2019 16 inch Macbook Pro that I purchased a couple of months ago and one of the main reasons was because I hated how hard and loud the fans would blow when I'd hop on zooms. I bought this new model and the problem did improve. But after updating to BIG SUR a few days ago the issue is back and louder than ever. But that's not even the worse part...


The worst part is I bought this laptop mainly for video editing. And a week ago before the update I was editing a project filmed in 1080p perfectly fine. Everything was as smooth as butter and fairly quiet. After updating I went back into that project yesterday and today to finish it up and no matter how many times I restart my computer and close every other app other than final cut pro, every time I start editing the footage the fans start blowing full at force and I'm experiencing a serious lag as I play the video I've been editing on my timeline. An issue I was not experiencing before the update. It's literally the same footage as last week and the only difference is I updated my OS.


I'm so upset by this, I feel like this update has ruined my smooth workflow, slowed everything down, and made the experience of editing very annoying as everything lags and the fans are super loud. I spent close to $5k to get an almost fully spec'd out laptop a couple months ago and it's now operating slower and worse than the 2015 model I had. Thanks for making that entire purchase I just a complete waste of money. I seriously hope you guys fix this issue ASAP in an update!
