My new MBP messed again. The volume icon is grey and there is no sound. When I plug in the headphone, the icon become black again. It's a hardware switch malfunction, which sometimes happens to iphone too. Does anyone have this kind of ****** problem for any other thousands of dollar expensive electronic devices? Apple's hardware and OS are so terrible, if they can't continue to come up with innovative designs, it's gonna fade away again sooner or later.
