I know, I know.  I'm being extremey finicky and it's effectively a non-issue.


I've done some research and it seems like many keen eared users have also noticed this on other MacBook models.


Whenever the backlight is turned on, if you put your ear to the keyboard around the '8' key there is an tiny tiny electrical buzz (almost like a dimmer switch - which doesnt surprise). By tiny, I mean the room has to be near silent to even notice this, however, I often use the machine in bed in my flat and ever since notcing it it's driven me crazy worrying it's a defect.


So my questions are:

- Is this normal and functioning correctly (there are no symptoms)

- Does your MacBook (preferably Retina) have this extremely faint buzz.


As said, Im being extremely anal, but having paid £2500 I want this thing to be out of box perfect.
