New Client + Instruments+Mac= No Sound :(

[WillaWonka]

So I've recently downloaded the recent V6 client, which is 10x better then the old v5.11 or something. The frame rate when my client is full screen, has an average of 20-21 fps, which is best. And I can actually see everything around me instead of having a small space to look through. Only problems I am having with it is the instrumental sounds. Whenever anyone plays any musical note it doesn't play on my computer. i tried downloaded the Instrumental Sound Pack from the Install Packages menu and it still doesn't work, then uninstalled reinstalled again, still nothing. I mean the instruments are noisy and annoying as hell but hey, if I found good music that i want to play and have the chance to buy a instruments, well i'm SOL.
