Try charging on the right and not on the left

<i>high CPU usage by kernel_task is caused by high Thunderbolt Left Proximity temperature, which is caused by charging and having normal peripherals plugged in at the same time.</i><p>Did anyone ever figure out why exactly the temperature sensor was making kernel_task go crazy?

This doesn&#x27;t make sense, and I&#x27;m a bit worried: I &quot;cheaped&quot; out and have a &quot;left side only USB-C&quot; MBPro from 2019.<p>Should I understand that having any kind of load on the measly 2 ports I have on my 1600€ computer will lead to abysmal performance? Like, attaching a USB hub to add basic necessity like HDMI or USB A?

I noticed my 2019 MacBook Pro physically hot to touch even after being idle for 8 hours at night. Now I unplug my USB-C monitor and USB-C-to-USB-A adapter at the end of the day and that has solved the problem. Now when I come to the machine in the morning, it is nice and cool, and I plug-in my peripherals again. It seems Apple has noticed this sub-par pro performance and moved back to the MagSafe charger in the latest pro models. Also, for the cynical among us, I would like to point out that each issue I&#x27;ve had with a MacBook, Apple has fixed for free. Don&#x27;t assume they wont fix it until you take it to the Apple Store and ask.

Strange. The proprietary software you run after you perform a repair has a specific port requirement and you can only use the left side ports. I always wondered what was so special about these ports.

How does something like this happen without QA knowing and Apple fixing it?<p>I mean, it&#x27;s happening cause charging it, that&#x27;s something all users will do :S<p>Sounds a lot like the antennagate

I have set up several macs to spin up the fans more aggressively. Subjectively this seems to help a lot.<p>And the noise is not much worse, because eventually they spin at full blast anyway; just a bit too late when presumably thermal throttling is already hitting.

Before I found this solution, my MBP would basically hang up with the fan going crazy whenever I&#x27;d have an MS Teams call. It still feels ridiculous when it happens and I switch plugs. It feels like such a strange thing to have to do on a pricey device like this.

And here I thought this was about charging electric cars: <i>&quot;Audi thoughtfully put charging points in both fenders, but only the right one is suitable for high-speed use.&quot;</i> -- <a href="https:&#x2F;&#x2F;www.cnet.com&#x2F;roadshow&#x2F;reviews&#x2F;2022-audi-rs-e-tron-gt-review&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.cnet.com&#x2F;roadshow&#x2F;reviews&#x2F;2022-audi-rs-e-tron-gt...</a> (Picture caption, about pic #4 from the top.)

Earlier this year, suddenly had my 2017 MacBook pro freak out and freeze on using the camera or screenshare: fans would go nuts and cpu meters were completely loaded. After reinstalling and upgrading the OS with no luck it occurred to me to check for dust. Indeed, there was much dust and after a good proper clean all is normal again. I used compressed air for best results.

Non-obvious debugging involving a mental model of the physical world reminds me somewhat of “the case of the 500 mile email” [0]<p>[0] <a href="https:&#x2F;&#x2F;www.ibiblio.org&#x2F;harris&#x2F;500milemail.html" rel="nofollow">https:&#x2F;&#x2F;www.ibiblio.org&#x2F;harris&#x2F;500milemail.html</a>

This is the reason I have a couple of monitors lying uselessly on my table.<p>Everytime I connect an external monitor, it makes the GPU go crazy and overheats the Macbook enough to summon this kernel_task demon.<p>Couldn&#x27;t comprehend why one of the best laptops on the planet cannot handle one external monitor.

On my HP Envy x360 (2020 - AMD Ryzen) I got the same problem if the power is going through a USB-C Hub. My thermals are 10 degrees higher while charging through USB-C than when charging through the barrel connector.

I run a displayport hub connected to a M1 MacBook pro and i noticed it crashes sometimes when in the back port. So i have to keep it in the front port.

At least Apple realized USB-C only was a stupid idea after a couple of years and reverted...

Apple hardware quality and the design decisions have gone to shit since jobs died. The folks thet were feed up with the hype of his return to a diying company (and with a good reason, since the company really improved) are the ones keeping the company alive... In my opinion unless something changes it wont take long for it to be the dying company they use to be... They have a grat &quot;body&quot; but they lack the &quot;heart&quot; (and apparently the brain also)
