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. As the linked StackExchange thread mentions: But on reconnecting kernel_task would be at it again.Ī few weeks ago I saw this tweet float by:ĭo you charge your Macbook on the left or right side? Turns out right is better! Īnd yes, that totally explained my problem. TLDR If your MacBook Pro runs hot or shows a high CPU for the kernel task, try charging on the right and not on the left. The Intel Core i5-3210M is one of the fastest dual-core CPUs and features clock speeds. I have a working setup made from MacBook Pro (Retina, Mid 2012) connected to.
Many iMacs and MacBook Pro have two graphics processors. At the core of the re-design of the MacBook is the CPU based on Intel's Ivy Bridge architecture. If your machine has a gpu, consider disabling Atoms usage of it with: atom.

Upon disconnecting the charger, the load would drop back to normal levels. Only 64-bit systems are supported, and you can install the operating system on other computers.

CPU load and drain my battery – even while connected to a charger.
