It is suspected to be an issue in your settings as this hasn't been reported by anyone else.
What version of Cross do you use.
Is your 'Mix' knob fader full left.
Are your inputs set to none (if possible in your setup).
If still no good, please post a capture of your audio settings and of the GUI. Also some more info on the hardware setup might help.
I'm not really into Mac, but latest version is optimized for Yosemite, as Apple changed several things without backwards compatibility.
