I’m currently struggling with kernel task on my 1 year old Macbook Pro 16″ 2019.
Basically I’m currently using an external monitor which is connected to my macbook via a usbc to displayport cable which is connected to the right side of my macbook along side with the DC cable. On the left side I only have a dongle which I use to connect my mouse to my macbook.
Here are a couple of pictures showing my temperatures. I’d like to highlight the fact that I’m not running ANY task on my macbook. I just connected the external monitor.
What I did so far in order to try to mitigate the issue:
- Resetting the SMC
- According to some people, kernel_task is triggered by “thunderbolt left proximity” temperature, but it doesnt seem to be my case. I tried completely disconnecting the dongle, the temperature reaches ~38 degrees, yet the issue persists
- Completely wiped my mac to make sure the issue wasnt one of the softwares I had installed, but the issue persists even with almost no programs running in the background
- Tried different monitors and cables. I tried using HDMI cables and my old BENQ monitor and my television, the issue still persists.
- I tried using my macbook in clamshell mode and I bought a vertical laptop stand because according to some people it helps dissipating heat, but of course it wont work.
I know kernel_task is supposed to make the CPU less available to those processes which are causing the macbook to overheat, but why is it taking so much CPU when there’s literally no user processes using the CPU and the macbook is not even hot?
