Hey Everyone, My new Macbook Pro 15inch Retina is about almost a month old, and the past two or three days, it has happened three times where the computer shuts down, and says that the computer was restarted because of a problem, and click any key to enter. I did some research and it said its a kernel thing...I have no idea what that means. Is this a problem? My macbook is brand new and I love it, but don't know what is happening. Is this is ok, and just something that normally happens? Very nervous! Thanks for the responses in advance!
