Overheating MacBook Pro after Big Sur instal

hey ya'll. Had fans running after Big Sur install. Found a fix. Activity Monitor told me that Goole Chrome Helper was chewing up most of my CPU. Deleted Chrome, restarted my computer. No fans running. Downloaded NEW Chrome (released a few days ago), opened still no fans. Problem has been fixed.

I stumbled across the same problem. Updated my MacBook Pro 2020 to Big Sur yesterday and since then my fans have been working like crazy turning on and off without any reason whatsoever. Before the update the fans turned on only while gaming, and were silent even with multiple applications.

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!

Mine also. It has been four to five days now that I have updated with Big Sur, and my laptop is still overheating. Battery is drained in under 2 hours, and I am not using more than one app. VERY frustrating. Someone said it was the Spotlight indexing. Uhmmm. I don't think so. GRRR!

One possible solution:

I had the same problem with my 2017 MacBook after downloading Big Sure last Monday. Nothing suggested here (like removing/updating Chrome, waiting for the program to be fully installed, etc...) ever worked for me.

I went to check my computer at my lab yesterday and the person in charge finally found the problem: Malwarebytes was the cause of the overheat. After removing it, my computer was back to normal (@Gérard/Pouchet: thanks a lot!).

It's a little bit tricky to remove Malwarebytes though : you may have to update it to be actually capable to uninstall it. I guess there should be some help online. Otherwise, we have to wait that Malwarebytes or Appel fix the problem.

I've had exactly the same issue with my MBP 13'' 2019. For me the noice hasn't been that serious, but simple tasks turn the fans of my computer at low-medium intensity. I updated as soon as possible and it hasn't improved as expected. It's really crazy how simple tasks like opening Netflix (ugh, it's the worst with Disney +) could do this. Specially since that never happened to me before updating. At times, I'd close every single program to see if something changes but the fans would still be running.

GUYS, CHROME . all has to do with chrome. Download the "intel version" from their download site and instal it over the one you have. Don't delete the old one. It will keep all your settings this way. Good luck!

The apple store at king of the Prussian updated Mac OS Big Sur on my MacBook Pro 13 today (November 22). Just used for 12 minutes, it pretty warm. I told the technician when I picked up the MacBook Pro, he just said it no problem. Otherwise I can request a cooler test. So I took home and it has the same problem when I use at home.

Sorry, but the entire OS is no good if it cannot run properly - that's pretty well cut-and-dried. If anyone puts something out there that has this many bugs, then, no matter what it is, it's no good to do what it is designed for, full stop!

I have shut down everything and am now unable to shut down the computer because it tells me that something is running, but there is nothing. So I checked in the background because the fan is still going crazy, and the thing that seems to be taking up a lot of power is this APUdevicesAgent. Some places say it is affected by external hd which I have but eject regularly. So far I can’t figure out why it’s running all the time and making the fan go crazy. (Just bought this MacBook in Aug, so should be fine). If anyone has any info, pls let me know! Thx!

Just a Chrome browser page is getting it crazy...

My MacBook is from 2015 but it's a i7 and it has 16GB DDR3, it doesn't suppose to have issues like that.

It might be about indexing files, so let's wait a few days.

If is not than, maybe the first update will fix that thing.

I think apple needs to update for the intel users again I have the same problem but this update so far is too well adapted for arm chips and not intel soon there's probably going to be an update that optimises for Intel too

Yup same here with my 2020 MBP 16 inch. Ever since updating it has been running extremely hot, almost to the point where I was thinking of freezing a towel to put under it to help it cool off. KernelManagerd is running in the background with 50% CPU usage, and I can't turn it off. And no I don't have any sort of anti-virus app to disable like Sophos

Mine was running aforementioned APUDevicesAgent in the background - I think it was trying to connect and sync to, but failing to do so, my iPhone. I had so mnuch connecting problems that it would not recognise or sync iphone, that I called Apple and was on for 1 1/2 hours, spoke to three different people and tried the same inane things only to be told in the end to wipe both phone and computer - I said no as this did not see a solution.

SOLUTION:

I force shut down the APUDevicesAgent (you can force shut down anything that it running in the background), force shut down the finder and the computer, then started up again, and now nothing untoward is happening, and I can sync my iphone with no trouble.

Hope this works for you, but if not, please let us know because this board is better than all the Apple "geniuses" put together!

Hi, I also am having issues with my Mac Book Pro, Mid 2015 retina A1398 model after updating to Big Sur. My fans continue to run, although it has not overheated. I am not technology savvy but I feel this should not be happening. Are there any suggestions maybe Apple can offer? Thanks!
