Greetings forum. I have a patch that sends DMX via the ENTTEC DMXUSB Pro using the serial object. For some reason my Macbook Pro running Catalina doesn't see the ENTTEC when I ask it to report devices using the "print" message. Other macs in my lab with older operating systems do report the ENTTEC and the patch works fine on them. The Catalina computer does see the ENTTEC box in the System Report and we're able to send DMX to it using ENTTEC's PRO Manager test application, it's just Max that's not able to connect to the ENTTEC. The Catalina machine is running Max 8.1.1. Any idea what might be going on here? Thanks!
