I have tried everything I can think of to install the drivers to my mac pro(mountain lion 10.8.2). I've installed monkey and tried different usb cables made sure my hd500 was plugged directly into my usb ports. Nothing is working. I've tried installing the drivers for my hd500 both from monkey and directly from the site. but it still shows up with nothing. I'm not sure what else I should try. When I pull up both the sys prefs and monkey it shows that my drivers are not installed when I've repetedly tried to install different versions of the drivers but at this point I'm at a loss for words. Any help would be great. Thanks
