I have Mac OS 10.9 and have done an uninstall and reinstall of the new driver according to instructions. All audio stutters and is distorted … sound from the DAW (ableton), from browsers, from movie playbacks, from iTunes. Are there any known issues — programmes working in the background, etc. — that mitigate against the C1 working in 10.9. It worked just fine with Mountain Lion …
Thx
