Worked great with the 2019 MacBook Pro. I installed the beta version for Catalina and decided to switch back to Mojave because there are too many bugs. If you do this for some reason WiFi won't work and no software will be installed without connecting to Apple servers due to t2 chip and security. Connected, works without problems.
