Noted the constraints over AVB with High Sierra. However the articles talk about recording over AVB. I'm recording with Capture via Firewire and have CS18 and RM32 connected via MOTU AVB switch. As far as I'm aware the control is delivered via UC Surface. So the exam question is whether the AVB issues interfere with this configuration. My immediate thoughts are no, but before I jump I'd like to ask the community if there are people using CS18, RM32 with Capture and UC Surface on High Sierra? I can't afford to overlook something.
