Hello MacRumors. I'm getting a bit tired of this now.. Feels like I'm pushing the power-button on my MacBook Pro every week because of the kernel_task. Here it is: Kernel_task is up at 100%. The computer feels very slow and I want to do a restart. Some of the apps have stop responding as well. I'm doing a normal restart which means the Apple menu - restart button. The grey screen appears with a loading picture. I wait and wait.. Nothing happens. So I hit the power button. And boom, the computer restarts and all is fine for a week or two. Then back to 100% cpu kernel_task and I need to do this all over again. I have done several Pram resets but nothing seems to work. I'm on a retina macbook pro with 10.8.2. I'm happy with the computer but not the OS. In the console.app I can't find anything useful. Maybe a fresh reinstall helps? I'm out of ideas.
