Sonoma 14 Mac book constant fan and overheating

This happened to me as well, what I did was downgrade back to Catalina10.5 and then back to Ventura 13. And it fixed the heating and fan problem. NOTE: this will reset your Mac. so make sure it is backed up.

1. Shut down mac
2. Press the Power button and immediately press and hold Option-Shift-Command-R.
3. Put in wifi and wait until utilties screen
4. Select the Reinstall macOS option
5. And then just follow the steps.

now your mac will be on Catalina 10.5. and then go to How to download and install macOS - Apple Support and download Ventura 13 under "use the app store"

The same thing is happening for me on my MacBook Pro, 16-inch, 2019, 8 TB SSD, 64 GB RAM, Intel.

I had hoped that the latest update would have helped, to no avail.

The most basic tasks create enormous heat. I wish that I had not upgraded from Monterey.

I may have run into a solution from another post. I went to the system settings and searched for login items. From there I turned off the Google LLC login item. So far, fingers crossed, my imac has stopped trying to take flight.

If all of these problems were caused by ONE underlying issue, it would already be known and fixed.

If any of the over 200 Posters who posted or clicked the "Me Too" button are actually serious about fixing the issues they are experiencing, you need to start a NEW discussion. This discussion has so many different computers and MacOS and slightly different issues, Readers can not possibly keep things straight to actually solve anything.

Be sure to create a title that will attract readers who can help, and include:

model year and screen size of your MacBook Pro.

Exact version of MacOS.

exactly what symptoms, and when they occur.

and an Etrecheck report:

This. I was having issues with my relatively small Photos library (20GB) not syncing, not detecting Persons/Pets/Duplicates, so I made a new library to test things out. With a fresh library I am getting the "Mac Needs to Cool Down" message and nothing in macsfancontrol indicates that anything is running hotter than usual. I am in clamshell mode FWIW.

I just upgraded to Sonoma in place from Ventura 13.6 where I did not have this issue. :(

This happened to me aswell when updating to Sonoma 14, and it became even worse when i updated to Sonoma 14.1.1. I have a Macbook Pro 2,3 GHz 8-Core Intel Core i9 with 32 GB 2667 MHz DDR4.

The fan is at full speed even though the CPU idle is at ~87%.

Apple needs to find a solution for this!

not make any difference. I just update and my mac battery is draining so fast :( I had to update for xcode version :(

There must be some apps running in the background eating up energy.

System Settings > Login Items > disable and delete all apps there and reboot.

Also uninstall 3d party modifier apps, VPNs, antivirus apps.

Apple don’t care about your complain, they only care about your money. That’s why they add prices every year on this concept products that never get completed. I have never seen any constructive feedback from an Apple customer service on how to solve/fix a Mac or iPhone problem. All their products are prototype. They keep increasing product price every year just by adding one functionality on an iPhone or changes it size from old to new. A company that does it marketing research by selling prototype products to it customers.

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.

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.

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.

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.

I just did the update, hoping there would have been some fix. 14.3 has the fans running even more than 14.2.

Ugghhh...

BS. The common denominator for changes is Sonoma. This is a typical deflect/redirect reponse.

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.
