I have found an unpleasant vibration/resonance when using the demo
"A Guided Tour of Macintosh". In the "Mousing around" section there is
a sound demo showing a piano keyboard. Click the key and you get
the sound. However on my MAC there is a bad vibration or resonance
from about F to A below middle C. Do other machines do this? Is
something loose in my machine or is there some inevitable resonance
to to placement of speaker, cavity size etc. (Let me know before the
warantee runs out).
Thanks
