This afternoon I found my new MacBook Pro running even though I am sure I had turned it off. Perhaps I don't know how to turn it off? I clicked on the
on the menu bar, and then choose "shut down", I later went back and closed the cover, I am sure the screen was black at that point, put the MBP in a kitbag, but when I got home, I realized the MBP was still on! What have I done wrong?
