High cpu use on mac os x 10.9 (Mavericks) by kernel_task

I switched recently OS X. I bought a new macbook pro 13' with retina and I'm amazed hot buggy it is. I'd compare it to Vista, to be honest (don't throw stones mac lovers).

One of many problems I've encountered was high CPU usage by kernel task. Solution? plug off your headphones. #amagad

Well, plugging in your headset should not do that in the first place. If unplugging your headphones helps, then it comes to mind that maybe you installed some software that is audio related that is messing up somewhere. Got any audio grabbing, streaming, equalisers installed? Get rid of them first to see if the problem is resolved then.

It's easy to write this off as an OSX fault, there are still many of them in Mavericks, but most of the time there is some sort of reason for this behaviour (incompatible software, for one).

Makes me wanna return my Mac Mini back to BestBuy just as quickly as I can. Maybe wait 'til they get these glitches out of their OS and maybe soon they'll ship the Mac Mini with an SSD.
