Question

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

For situations like this you most definitely need to open a support ticket with the support team so they can do a deep dive to determine if it's software or if there's a hardware issue. Answers is not the place to do that.

Please take a moment to register your AudioBox 1818VSL in your https://my.presonus.com account.
