Sonoma 14 Mac book constant fan and overheating

I started experiencing the same thing with my 2019 MBP. Turned everything off that I could, put everything on low power mode, still goes to 170F when in screen saver mode. If left on battery overnight it's dead in the morning. I'm sure this heat issue is killing my battery too. Certainly something is running in the background causing this heat issues. Come on Apple, fix this.

Hoping there is a fix to this issue soon. Ever since the Sonoma release my iMac's fans have been running at top speed. Have to constantly interrupt my work to put the cpu to sleep so the fans will shut off. This is a temporary fix as the fans will kick back in shortly after.

Tried that:

New MacBook Pro, 16", M3 Max, Space Black… - Apple Community

Very hard to give up the last Jony Ive designed MBP to go backwards to the new design with irrelevant HDMI and SD card ports, especially since they can't get the anodization right either.

No. Apple is doing exactly what they’ve been sued for many times. They are purposely putting out software to give the illusion that you need a new laptop. A top of the line MBP from even 5 years ago is still plenty of power and should last another 5 years minimum. There’s no need for an upgrade. There’s a need for good customer service for loyal customers who have ALREADY purchased laptops. Good lord you need some common sense.

This I agree. Mine is nearly 5 years old and doing pretty well. Not heating up, battery as good as it was new, etc. But, most of the problems the device owners usually get are due to their way of usage. How many users ever read the user manual, by the way? When we get a new dishwasher, we read the instructions, don't we? It has too many buttons and options than the last one.

Why should you want to have any MS AutoUpdates at login and in the background? Isn't its better to do that manually, and when you want, not when MS wants?

I've been experiencing the same thing on my M1 Pro MacBook Pro 14". I will say, however, that my computer has been running much smoother since the update, and many system animations are smoother. I don't know if these improvements are worth the overheating

I just updated my MacBook Pro, and now having issues. DID NOT have overheating issues and fans constantly running prior to update. Went from Sonoma 14.1 to 14.4, and now having issues. Don’t run anything heavy, and again was fine before update. Update caused my problem.

I have the same issue! The battery is just gone whenever I want to use my laptop again. It gets really hot and the fan is always working even without using any high-demanding software. (I have 2020 Macbookpro 2 GHz, 16GB LPDDR4X, Sonoma 14.4.1) Such a disappointment that my Mac causes a lot of trouble now with just an update.

When you use (or stop using) your Mac for more than a few minutes, if AC power is available, Plug it in!

Your Mac will NEVER over-charge.

Closing the lid REQUESTS (but does not guarantee) your Mac Sleeps.

For more predictable results, choose "Sleep" off the Apple menu.

I have fixed the issue for now.

I removed the screen from my iMac to upgrade the RAM and add a drive.

While I was in there I found the processor cooling fins to be thick with dust. I Hoovered them out then checked the case and sure enough, the vents at the bottom of the case were clear (I vacuum them regularly) but inside there is a plastic grille running the whole width of the case and it too was clogged with dust.

This is speculation on my part, but I'm guessing that Sonoma places a higher demand on your processor, and if your system was already maligned with cooling issues, then upgrading to Sonoma is the straw that breaks the camel's back.

Anyway, managed to get the screen off and on a couple of times without damaging it. Last week I laid it down to clean some adhesive tape off the back of the case and caught the corner of the screen on my work surface and cracked it :(

Still - at least it doesn't overheat anymore.

can you tell me the spec you have, because i have the same Mac (2019) but in Core-i9, doing noting my mac goes up-to 100 degree's when only watching youtube and a couple of tabs open on safari, i have nothing running in the background , so i am really confused on what the problem is.

Although I would usually recommend against update on older models, but I did noticed that my Adobe PS runs much smoother with the SONOMA 14.1.1 update.

Usually I would expect it to just add unless feature, and slow it down.

Me too! Same thing

I have been having this same issue as well. If I downgrade to an older macOS version would other packages and installations for my coding tasks be backed up too?
