    Hi guys - i recently updated my 2.4 ghz leopard macbook and i've noticed that it no longer makes the recognizable double-tone high pitch machine noise when booting up, coming out of standby or loading up vmw fusion.

    Just out of curiosity - what happened? everything is running normally and from what i can tell nothing has changed.

    The noise you refer to is the MacBook checking the DVD drive for any inserted optical media. So maybe the update (system or what?) has also changed that behaviour.

    There was an EFI update followed by a SuperDrive firmware update recently that would make the machines no longer run the optical drive check at every powerup/wake cycle.

    i see - well that makes perfect sense. while i had grown accustomed to that noise - i imagine stopping unnecessary checks/movement/noise etc can't be a bad thing.

    thanks guys!
