Not knowing about this issue, I believed it was the apps that came with the webcam that were causing the fans to spin up and the machine to slow down. Oddly enough, I personally ran into this problem a few months ago while reviewing a USB-C webcam. Again moving power back to the right side, restoring State B, resolves the problem immediately.Д®rgo, high CPU usage by kernel_taskВ is caused by high Thunderbolt Left Proximity temperature, which is caused by charging and having normal peripherals plugged in at the same time. Moving power back to the left side, restoring State A, quickly restores the temperatures and kernel_taskВ again comes back after 3-4 minutes. The left side temperature drops and the kernel_taskВ goes away within about 15 seconds. State BВ cures the kernel_taskВ problem by moving power from the left ports to the right. About 3-4 minutes later the dreaded kernel_taskВ high CPU usage starts.

You can see the Thunderbolt Left ProximityВ temperature sensor rise quickly.

State AВ a USB-C hub (a mouse and keyboard, plus power) and a USB-C HDMI 2.0 adapter, both on the left side. Image via вЂњAdamвЂќ on StackExchange showing the macOS kernel_task dominating CPU usageДЄdamвЂ™s graphed test results are too big to post here, but they conclusively show that plugging in power on the right side resolves this runaway state. Suddenly the fans spin up on the MacBook Pro and CPU usage is maxed out. Which port should you charge your MacBook Pro With?ДЄdam discovered that if youвЂ™re charging your MBP using the left-hand ports and have other accessories plugged into that side, the computer heats up so much that a sensor - Thunderbolt Left Proximity - is alerted and a macOS process named kernel_task appears. The cause of this sudden quirk? Adam, a user on StackExchange, came up with a way to test what was happening and fully documented his results. The result? The machine would slow down while the fans on the device went into high gear. On StackExchange and other sites, MacBook Pro users documented situations where charging using the left side USB-C ports caused unusually high CPU usage. While these powerful notebooks have USB-C / Thunderbolt 3 ports on both sides, weвЂ™re going to tell you why you should charge your MacBook Pro using the ports on the right side. Photo via hardware Do you have a recent MacBook Pro? doh! What if.Right-side USB-C ports on a 16-inch MacBook Pro. You smell it once and its easily recognizable for the rest of your life. But since I didn't see with my own eyes, where each was soldered I thought I'd get a second opinion.the center 'core' wires carry the voltage (vo) and the outer 'sleeve' goes to ground (gnd), right? Seems like a stupid question, but I keep thinking 'what if.?' What if I plug it into the wall, hear some crackling sound, then smell the sharp smell of burning resistors, diodes, capacitors etc. It will be a normal apple 45w 24v t-connect magsafe adapter, from the core2duo era of macbook pros. I didn't unsolder the cord from the board myself, and its been long enough since i've done this, I thought I'd make extra sure I have each of the 2 wires going where they should. There's no wire to splice onto, so I'll have to solder it to the board. I've got a good power adapter I can use with a spare magsafe cord I have. I'm going to be without an adapter for a few days, so I'm going to put one together from my collection of parts I've saved over the years. Replacement MagSafe cord- I found mine on eBay for like $16. Capacitors can hold a charge for a while so it's best to leave the adapter unplugged for a bit prior to working on it.

Next, I decided to figure out how to crack open the adapter and replace the entire cord and that's the process I'll demonstrate with this instructable.Д«e careful and make sure the adapter is completely discharged. Then I decided to splice out the shorted sections of cord which did work but left me withВ relativelyВ short cords for charging the computer. I used to buy new MagSafe adapters but that got expensive fairly quickly. Having owned several Apple notebooks which utilize the MagSafe adapters I've seen my share of failures.ДЄnything in from stuck pins which prevent the computer from charging to my cats deciding the adapters are made out of some rare form of addictive kitty-crack and shorting out the cord by chewing on it.
