What would be the average CPU for this task? I read around about it a bit and got the whole "it's not really a task" shpiel.... I'm running an iMac 27 core i7 with 8gb ram. I run parallels win7 plus Photoshop cs5 light room and iPhoto.... All at the same time often processing in parallel.... The kernel_task goes to around 40% ..... From what I'm seeing in forums I don't need to worry unless it's past 100%.... But want to get other's view....
