[Elecraft] USB to Serial on MacOS

[Doug Person]

I know there are a lot of guys that are very good at macs here. I'm 
stuck. I'm trying to get a USB to SERIAL adapter to work on a mac. I've 
tried 4. None work. I look at System Information but I honestly can't 
tell if there's a serial port adapter there or not or if it even works. 
I did install Prolific drivers. OS is 10.13.6.

Thanks for any help.
