I recently got a new 600Mhz snow iMAC and an iSub a few weeks ago I picked up the 10.1 update and to my suprise Ten does not fully support the sub it periodically turns off and there is no control for it in the sound panel. I've already been to apples support page for iSub and it doesn't hint at an update anytime soon does anyone did they leave it out for some weird reason anyway USB is still a little iffy in 10.1 so far
