Hi. I would like to be able to close my iBook and still be able to listen to music playing in iTunes through my headphones. Is there some sort of patch or program that would make this possible? Or would I have to somehow mess with my hibernation mode settings? Additionally, sometimes I shut down my iBook and think that it is completely off and close the lid, and it automatically goes into hibernation mode. Any way to get it to go ahead and shut down completely? Thanks.
