Sonoma 14 Mac book constant fan and overheating

Hey guys, try using the software CPUSetter to limit the % of CPU used by the processes that are using too much CPU processing power. In my case, I limited the processes "sharingd", "contactsd" and "CMFSyncAgent" to allow each of them to use only 10% of CPU (see screenshot), it resolved my issue, but you can also check which processes are consuming more CPU in your case in Activity Monitor. I have also downgraded to Macos Ventura and it looks like it helped a lot.

Here to echo a couple others... changed my wallpaper and screensaver to plain photos, not rotating images or motion pictures and the fan speed reduced immensely!! Common, Apple!!!!

Edit: solved it for about 5 min, now back to loud

This was the easy fix. I turned my Wallpaper to a static or dynamic image and the fans ramped right down. MBP 2018, Radeon Pro Vega 20

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.

I could recommend you check you fan, it might be dead.

If you want to do a quick self check, you can start up the computer by pressing down Option D, it should give you a code if something is wrong.

That's the same thing the repair shop did for me, and told me my fan is dead.

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.

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.

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 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.

Apple movers and shakers do not visit here. If you want them to know you think this is a problem, you need to contact them at Apple support and work with them fro either find a solution, or file a bug report on your behalf.

or you can use the Product Feedback page to tell just them about it.

Let's don't sink this thread. Apple needs to fix this terrible overheating issue!

Thx, your method was actually my issue, too.

i stopped randomize wallpaper and now my kernel_task is back to normal, no more over hearing CPU.

Immediately after an upgrade and for at least the next several hours of 'awake but not excessively busy' time, your Mac will be rebuilding the Spotlight index. This index of every word in every document is used to provide fast searches and also a quick reference of what files have recently changed, used to make Time machine run MUCH faster than otherwise possible.

After Spotlight search becomes available (indicating indexing is done) and your next Time Machine backup has completed, things should calm down.

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.

downgrade takes all afternoon. MacOS will never install older version unless all traces fo newer version are GONE.

You have to make a full backup (which you should have already) ERASE your disk, install MacOS. and then restore your files from backup.

Instead of doing that, Consider downloading and running this little "discovery" utility, Etrecheck. it changes NOTHING.

it contains little tests for speeds of devices, CPU utilization, memory usage, energy usage and a digest of recent problems, in one easy to use package. it does not even need to be Installed.

if you follow the directions faithfully, its report (pre-laundered of all personally-identifiable information) can be "Shared" to the system ClipBoard, then Pasted into an Additional text window in a reply on the forums.
