Hi all, I've posted this on the Apple forum as well, so sorry for the cross posts... But firstly I must say I love this computer (Black Macbook 2Gz). It's fast and looks great. But this noise is rattling me. I do audio/music for a living and, well, it ain't really cuttin' it. I've 'Googled'. I've watched the 'moo' movie and I've and downloaded the widgets but to no avail. I'm beginning to think that maybe this sound isn't the 'moo' that everyone is talking about? I've included a little (very little - 10 secs. lo res) MP3 of the sound in the link below: http://www.theflowershoprecordings.com/moo.mp3 Any ideas? Cheers and thanks for the help, R.
