I am in need of help. I have a MBP w/Retina from August 2012. It has worked beautifully until a couple of weeks ago (I think maybe when I installed Mavericks), and it then started to slow down considerably.
I have noticed high memory usage by 'kernel_task' but have no idea what that is.
See the attached picture to give you the idea. Please help me to get my MBP w/Retina back to being awesome again.
