It's not loud, it's annoying. It is whisper quiet, but the high pitch sound from it is unbearable. It's like a very very VERY VERY quiet whistle. Barely....just barely noticeable. But it is non stop and so darn annoying. Like I keep saying, I would like a louder Mac without the whine.
My Mac Studio Ultra is dead quiet. It's a great computer.
What was Apple's response when you inquired about having that fixed/replaced?
