Sonoma 14 Mac book constant fan and overheating

First get rid of CleanMyMac and such apps from your Mac. And then go to System Settings > Login Items > disable and delete all that's there. Then reboot.

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.

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.

One more update: I recommend turning Power Nap off completely for battery and power cord. I did this and my MBP is running about 5 to 10 degrees C cooler overall. It will jump when opening apps, doing more intense work but it cools pretty fast. I've got 6 applications open right now and i'm at around 52 C.

Computer might heat up depending on the apps you use, so what are those 6 applications?

I was having the same Sonoma problems with my 2018 MacBook Air. I did the Shut down keyboard process, and then disabled all auto-starts. Ends up for me, Chrome is what is causing the fan to come on. As soon as I open it, fan kicks on. Close it, it goes off. I have been a Chrome users for years, but luckily I pretty much only use my laptop for remote access into my company's systems to work. It's frustrating to have these fan issues each time we upgrade.

I have the same issue but since started using Chrome instead of Safari for a couple of days my powerbook pro 2019 w/sonoma has not run the fans.

I had the same issue with my 2019 MBP. I decided to go back Ventura as it was reported to have solved the problem. I was going to use my last back up with Ventura. I had to use Migration tool but inadvertently just migrated my latest back up (same day) under Sonoma and only migrated Apps and System - not my files. When I restarted my MBP was running much cooler. Idles around 50 to 60C now. I had to use Disk Utility to fine my partitioned drive with my files but it seems to have solved the problem. I don't how but it did work. So, rewriting the file seems to have fixed the problem for me. I also let the laptop sit overnight on battery and it was no longer draining. Now, when running Chrome, mail, Zoom and a few other programs it runs around 68 to 73C. I did install SMCfan and set it on high RPM, I run a cooling pad and run an outside fan on the back too, which all appears to be helping keep it in the 60's. Still warm but not the 80's or 90's C I was getting. Hope that helps!

FYI, when running screensavers it still pushes into the 70's C. So, I also set Low Power mode in the Battery setting for All the Time on battery and plugged in. Whatever.... just don't want this thing overheating.

Idling at 50°C is not cool enough at all. Mine is a 2018 15" MBP and the battery temperature while running Safari (5 tabs), Skype and Finder is 26.4°C.

You must be having some 3rd party apps running in the background. Check in System Settings > Login Items > disable and delete them. It could also be that the air vents are clogged, or the fans are dusty that they won't pull in enough cool air in.

What the use of using Chrome on a MacBook, when Safari is made for it?

Chrome is a heavy energy eater in Linux and Windows too. If you need to use Google products, why not use them online on Safari and save the headache?

2019 iMac, core i5, 500gb SSD 16gb RAM.

Same. Upgraded to Sonoma (WHY, IT WAS WORKING JUST FINE????).

Now the fans are cutting in constantly, processor temps up in the 90s (celcius) and my Adobe apps are slow as F. Activating my second monitor makes things worse. I have the same refresh rate set.

Bug reports remain unresolved.

Going to back up and downgrade to Ventura when I have a spare hour.

Discussions here are not tracked.

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.

Official Apple Support

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

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.

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
