Catalina and Mojave drivers are notarized. Legacy drivers (signed) for OS X 10.13, 10.12. 10.11, 10.10/10.9, 10.8, 10.7, 10.6, 10.5 (PowerPC) are also available. I purchased your driver and I am happy to report that it solves both issues I saw with the other drivers. I'm having trouble with my CH340 Arduino UNO, it says device or resource busy when I try to access /dev/cu.usbserial-1420. Have you got it to work in Catalina? I already instealled the CH340 drivers and still doesn't work.
