    Hey all. I bought my rMBP last week, and it's really an amazing machine. I just noticed that if I dim the display brightness down about 3/4 of the way, the screen starts to emit a high pitched humming noise. It get's louder as the display gets dimmer...

    Also, whenever the keyboard backlight is on, there is a similar high pitched buzzing noise at all levels of brightness.

    Just wondering if anyone has experienced the same thing, and if this is normal behavior? Thanks for the help!

    I don't have a rMBP but I doubt that is normal behavior.

    Thanks for the response, Dark Void! I've made a genius bar appointment for today, so hopefully it'll get straightened out there.

    Hi, did you manage to solve your issue? I can hear it too - especially with my keyboard backlit - whenever it's on - there is quite noisy buzzing, which i can hear even when sitting half a meter from the macbook...

    It's normal... the new iBee feature is just showing off. ;)

    Very funny ;) My hearing is over sensitive for that kind of electric buzzing. So yours does that too?
