I'm able to run JMRI on a Mac running OS 10.15.4 and an RR-Circuits LocoBuffer-USB. I don't know if this will work for you, but I found that I did NOT need to install the drivers recommended for LocoBuffer. The system just recognized the device when it was plugged in and all was well from there. I did try installing the extensions as the documentation suggested, but then it wouldn't work. So I uninstalled them and it's working again (with a reboot in between to ensure they weren't still running) Strange, but since it was working I stuck with it.
Thanks, I understand some macOS releases have an Apple-supplied FTDI driver in /System/Library/Extensions.
