My mid-2015 MacBook Pro is having serious performance issues. I opened the activity monitor and realized that the kernel_task is showing a load of more than 200% when it is no worse than that. I noticed that in this load condition, besides being slow, it is also overheating. The problem only happens when I connect one of the display ports, because I like watching Netflix on my MacBook Pro. I imagine that something may be wrong with the chassis cooling, but what does the kernel_task have to do with it?
