Audio-Technica 2020 mic works on 2011 Air running El Cap (USB 2.0) and on 2012 MBPro 13" (USB 3.0) running Sierra. Isn't recognized in System Preferences->Sound nor in the USB device tree in System Information on the new Air running High Sierra out of the box. Mic didn't work from the jump or after patching with latest HS patches from App Store. Booted it into Sierra from an external drive and mic still not seen. Any thoughts on why the hell a simple USB device won't work on this new Air? AT support tells me it's Apple's problem HS and the USB Audio Codec. Seems more like a hardware issue since it doesn't work with Sierra either. Anyone with some insight? Thanks.
