Here is the system configuration: MacBook Pro (Retina, 15-inch, Mid 2015) I have a maxed out MacBook Pro which can't handle two monitors? It's kernel_task which is using absurd amounts of CPU (sometimes spikes up to 600%)īefore I used to have a high CPU load as well (with the additional monitors connected), but that got resolved after following the instructions in this article, CPU usage is too high with Yosemite and an external monitor, kernel_task spikes to 600%+. When I have the monitors connected, the CPU load is very high with fans running at 5500-6000 RPM and a processor temperature of 54☌.
I connected them using Mini DisplayPort to DisplayPort Adapter cable to my MacBook Pro. I recently ordered two 4K monitors (LG 27UD88).
