I recently bought an iMac Pro. It runs the latest version of Catalina (10.15.3) Now when recording audio, there are lots of clicks and pops. Also, the USB sync light flashes red/blue continually. I tried to reinstall the driver, but now only the universal control app exists on the website. I downloaded it. the only option it gave me was to update the firmware, so I did it. Now the blinking light continues, but in addition, the Mac no longer recognizes the AudioBox 1818VSL in the sound part of the system preferences. It also isn't listed as an available interface in logic.
Any help would be much appreciated
