Overheating MacBook Pro after Big Sur instal

Yes, BLoi, I have the same problem. I too disabled Google Chrome Helper from within my Chrome settings and it does periodically appear in the Activity Monitor with an increasingly high energy impact. I force quit the application and all is well for a while. I find it hard to decide where to place the blame - Big Sur or Chrome...very frustrating

I had the same problem after I installed Big Sur on my 2014 all-solid-state Mac Mini. Most of the time the computer became almost too hot to touch. Updating to Big Sur version 11.4 actually seemed to make it worse. I eventually found that inactivating the new Ken Burns screen saver cured the overheating problem. (I'm now running the Word of the Day screen saver.)

Big Sur 11.4 has other problems: It occasionally restarts for no apparent reason, and I sometimes lose unsaved changes in Photoshop or Microsoft Word documents. Warm restarts are often very slow – five minutes or more – whereas restarts if I turn off power and restart the computer, or do a warm restart soon after a cold one take less than a minute, and every time the computer is restarted, even by my choice, it tells me the restart was due to a problem. Zapping the parameter ram doesn't cure any of this. It's all very irritating. I'm hoping Apple gets a handle on these issues and provides a better update version 11.5. Hard to understand why a company with such good products would introduce such a bug-laden upgrade to its operating system after all these years. Overconfident programmers and insufficient testing before releasing software is a well-known problem; could management changes that come with growth have caused Apple to lose understanding of that?

In addition to inactivating the "Ken Burns" screensaver, which pretty much cured the overheating problem, I recently discovered that unmounting all my external drives (or Command-E to eject each of them) after restart eliminates most of the other problems I have been experiencing with Big Sur 11.5.1 (i.e., Finder freezes, frequent unsolicited restarts for "problem", and long 5-minute+ restart times). When I need to access files on any of the external drives, I summon up the Disk Utility and reload that drive just long enough to do the work, then unmount it again.

I'll be interested to see if Apple's promised upgrade to the next OS generation eliminates these problems or if perhaps they are totally oblivious to all the wasted time and anger these issues are generating among Mac users. Or perhaps they could just provide users who choose to do so an easy path for downgrading to Catalina. That OS had all the bells and whistles I ever needed without the problems.

I deleted bitdefender antivirus and that solved the issue. After deleting the antivirus make sure to delete all its kexts.

It is the mail app pushing the heat on your Mac.

If you kill the process, heat goes away. Hopefully @Apple fix this real soon.

Cheers!

Feb 2021 and still heating issues with Bigsur. I installed it recently. I did some tests in safe mode. It is the I/O. When I run "ls -R /" temperature goes from 53 to 90 Celsius.

I had the same issue and when I checked activity monitor, secd (security daemon) was in process using over 100% of the cpu causing heat and fans to work in a high speed.

secd involves iCloud therefore I logged out and logged in to myMac using the appleID , Now works perfect.

Had the same issue. For me it was mds_stores process that caused overheating. This process is indexing for Spotlight. I dont use Spotlight so I turned off indexing by running this command:

sudo mdutil -a -i off

It immediately helped and CPU temperature went down

I was having the same problem (MacBook Pro 2015) for weeks and it wasn't going away, but somehow deleting Chrome helped on my computer too. It's only 1hr post deletion but the problem for now seems to have gone away. I need Chrome for work so at some point I'll need to reinstall, but amazingly the fix worked or at the very least helped.

I had the same heating/battery issue for many months and finally found a way to resolve it. Tried all the normal routes: resetting SMC, restating the machine, waiting for the indexing to complete, etc. The truth is, nothing really worked for me and it was painful to work on this machine. I feel that it is kind of sick (having a fever) due to some software bugs.

I think the root issue is with intel/apple's algorithm for turbo boosting (or some background programs triggering it constantly). In normal use scenarios, there is really no reason to turbo boost. You can see the issues clearly with the application called Intel Power Gadget. There are regular turbo boosts (frequency spikes every minute or so) even when the laptop is idling. This is bad software engineering. Resetting the SMC could not fix this issue.

I installed an app called Turbo Boost Switcher and with its help the temperature went down from 70+ C straight back to 40- C and the system is running smooth and calm again. If we use external displays/high graphics apps, the GPU may kick in and that increases the temps, but at least that is known/expected. If I plan to do some high performance tasks, I can purposely and temporarily turn on the turbo boost feature while plugging in the charger, and expect some high fan work periods. That is okay, too.

In my opinion the Turbo Boost feature should be turned off 95% of the time, unless the user wishes to have it. Otherwise it is a really bad user experience. With the turbo boost turned off, I am a happy camper and enjoying my macbook pro 16 very much again. Hope this helps you!

I turned off the Google Chrome helper extension and my fan no longer kicks on I also reset the SMC before hand as well. How do you turn off the turbo booster? I have a MacBook Air maybe that doesn’t apply

I've had this problem ever since installing Big Sur on my Mac Mini (Late 2014), 3 GHz Dual-Core Intel Core i7, 16 GB 1600 MHz DDR3 Memory, with 1TB Solid State Internal Hard Drive. Currently at Big Sur 11.4, and problem continued, computer becoming very hot during use and while asleep. In addition, simple warm restarts not requested immediately after restarting often require five minutes or so and indicate computer was restarted because of a problem. Also, Finder 11.4 frequently crashes and sometimes restarts on its own.

Recently I discovered that deselecting the Ken Burns screensaver appears to cure most of these problems. I switched to the Word of the Day screensaver, but others also appear to help. My computer is definitely running cooler, also much cooler when in sleep mode with the screen saver active, and a lot fewer (almost none) Finder crashes or unsolicited restarts during use.

Are you using the "Ken Burns" screensaver? If so, go to System Preferences (under Apple logo menu), "Desktop & Screen Saver", and switch to "Word of the Day" screensaver. That made a big difference in heating for my Mac. It didn't seem to matter if the Screen Saver was actually being displayed. The overheating occurred even when using the Mac for other tasks.

finally found the solution: just install macos catalina

Still running fine after PRAM and SMC - 5 days on
