I was able to circumvent the expected Security Check (never a good thing to do) but believe WaveForms v3.12.2 needs to be updated to have a digital developer certificate or it will stop working (no override permitted) in a coming release of Catalina. For macOS users, System Preferences, Security & Privacy, General and there will be an option to Lanuch Anyway. This is not a good idea and you are on your own once you do that. DO NOT BLAME ME.
The FTDI Extension was blocked, but the device appears to be working with the FTDI Driver that was already installed.
This software needs to be updated for digital developer certificate or it should not be considered for use on macOS.
