Where does it say PC that would give you the thought that it's Windows capable? It has MAC all over it (says Intel or PPC but that does not mean Windows) and the user manual is Mac only. And it's not a music server product; really a DAW (digital audio workstation; ie. a client product). Probably better for the Apple Forum. But what the heck if there are folks here that serve to an Apple laptop I guess, they could use this..it doesn't interface well to iTunes though..? At least that's what the reviews said were it's downsides..
Edit: the iTunes downside was that it cannot save presets, so the reviews say it is limited to one app. Still if that one app is music it should work.
