My new mac is making a loud noise, but the speakers are off. It is like a buzzing white noise. Anyone know how to stop it?

Is your kitchen light Fluorescent ? or a compact bulb ..... the ballast maybe throwing off RF interference ........ like a Cell Phone too close to your speakers ...

My lights are track lighting on wires, the think in the center needs to be replaced (It goes bad about every year and a half.)

If it only happens in the kitchen, can you isolate it to the lights (by turning them on and off)?

Whatever the issue is, the lights should not be emitting enough RF noise (even at a harmonic) to bleed into the audio circuitry of your Mac...

Like RadioPatrol said; if it was fluorescent, then this is possible as it could be a bad ballast (fluorescent lighting is "noisy" electrically) , but with track lighting, something's not right. :shrug: - OR the filtering for your audio circuitry could be bad on the Mac, but the problem should happen in other places as well.

Try using a power filter.

Her power brick should have a power-filter built in, unless that is dorked... but you are right, it would be a good test to try a power-strip with sometype of power filtering, or a simple filter...

Another way to test is to run from battery alone and see if it does it (no A/C in, no electrical line noise from the house.) :yay:
