Kernel_task on a new MacBook Air
I bought my MacBook Air a few days ago and am very pleased at how well it runs... except when it doesn't. In the course of using the computer, all of a sudden things will get very slow and the mouse and keyboard will barely respond. The mouse moves erratically and keypresses take a while to show up.
Opening up Activity Monitor shows that kernel_task is taking up 50%+ of the CPU. I've tried to isolate any programs that may be doing it. Shutting down iTunes now seemed to have bring kernel_task back down and the system responsive. But other times it doesn't.
Is this is a known bug? Can someone point me in the direction of a solution?
