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.
