Overheating MacBook Pro after Big Sur instal

Same here in Toronto. Installed Big Sur prematurely before waiting for online reviews or issues. Sadly, I can probably cook an egg on the underside of my beloved 500Gb SSD MacPro. Nor can I find what is running either. Any one have a way to revert back from my external backups?

Hi I had the same trouble with my 2020 MBP 13” i was able to revert to Catalina . Although i had Time Machine backups when i tried on Big Sur they dis not seem to work properly until eventually I effectively was left with a brick. However I guess that when I went into full restore to factory mode it must know the MBP originally shipped with Catalina so thats what it downloaded and installed which I am please with. Even better although it downloaded Catalina from the net , it did restore most of my apps and most of my documents etc which I guess were sitting in the iCloud. I was pleasantly surprised to see everything almost back to how it had been minus a few odds and ends and minus Big Sur. Read up in how to restore your Mac but ensure you have iCloud enabled and synced first. Good Luck.

Depends on what progarm you use to do your backups. I use Super Duper which clones the HD making an exact copy. Therefore, to restore, I just need to erase HD then copy back from backup. It takes a while but I revert to the exact state as when I did the backup. In fact, I usually keep previous OS backups for weeks following upgrade in case. True, I lose everything created since the backup but I return to a state where I can use the system. Hope this helps.

My Macbook Pro is really heating up and making a noise with its fan after the upgrade. I have shut it down several times and still it keeps heating to a level it is no longer a laptop but a hot plate. I need help for this one as it is painful to be in office or at home working with an instrument that is blowing hot air.

Activity monitor showed massive energy impact by Google Chrome Helper so I "quit" that. Here's a good article to help you disable Google Chrome Helper. I think having done this may have solved the problem for me. Good luck everyone. https://www.wired.com/2014/10/google-chrome-helper/

When I’m downloading movies for example on my MacBook Pro 16 or anything else, it starts to heat up abnormally, like wtf apple, I see that temperatures on my processor start to go up and down, as if the computer is making some computations, and it’s draining the battery super fast. It’s just downloading, there is no reason for it to heat up..

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 am not an electrical engineer, and I shouldn't have to be. I am, like many others that purchase Apple products, a consumer. I have performed all the recommendations and to no avail. Catalina had a few problems when it was first installed; however, it didn't take months to correct. The only conclusion to make is that Big Sur was designed with some major flaws. It will either require a major fix/update or if you have the ability to restore Catalina, then that is what I would recommend, until Big Sur gets a fix. For those who haven't updated to Big Sur, wait until the fan issue/power drain issue has been resolved.

I have the same problem with my MacBook Air. It's been 3 days heating and its fans working hard continuously. It is problematic because I won't be able to work (I teach by Zoom) with this noise in the background. I'll try leaving it logged on until tomorrow, but last night it was really noisy and couldn't sleep well due to my computer's noise and my concern with its functioning...my computer is my main working tool.

I can confirm that I actually tested this and my Macbook pro 16 is randomly Turbo boosting even on normal or low load. I also tested with Firefox, chrome and Firefox developer edition being used and chrome helper is not the cause as some stated as the laptop will turbo boost regardless.

Turning off Turboo boots using Turboo boost switcher my CPU temp dropped from a constant 75C to 40-50C.

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 called Apple support team and we tried everything for 5 consecutive days. Nothing improved the situation. Lastly, my boyfriend did a search online and found the problem. In my case, after updating to Big Sur, the problem was Google Chrome Helper: https://www.wired.com/2014/10/google-chrome-helper/

Try removing it. You will find it in your Activity monitor. Good luck!

Same thing happened to me. MacBook Pro 2018 regularly got too hot to keep comfortably on lap after Big Sur Upgrade. Then.....my MBP bricked completely. Genius Bar says I have to send in for $575 repair fee. I think Apple owes me a free repair. I upgraded per their suggestion and my computer died due to known power mismanagement issues.

Oh nooo! What a nightmare! I couldn't eliminate definitely Google Chrome Helper, it reappears continuously in my Activity Monitor, heating again my laptop above 100 degrees. I don't know what to do either, I regret having uploaded to Big Sur, it is a disaster.
