Guys, The AC Adapter of my new Macbook Pro has started making a weird noise. It is not very loud, but is noticeable if you're close to it and is a kind of sizzling. If it is plugged in, then you can hear it, even when you disconnect it from the laptop but keep plugged it in the socket. Do you have the same issue? I haven't noticed it earlier, so maybe it started doing it recently... Should I call Apple???
