Ok, I have both windows and mac os on my imac. I can connect my home speaker system to the Windows partition fine; Auto installed the drivers and everything. But when I am using my Mac OS the drivers do not install or they are nonexistent. I looked online for hours trying to find a driver to download but to no avail. If anyone can help me get this resolved so that I can run my mac os audio through my speakers at home (JVC RX-D412 AUDIO/VIDEO CONTROL RECEIVER) It would be greatly appreciated.
