nrfjprog cannot connects to PCA10056

Ken

nrfjprog is reporting "Cannot connect to J-Link." while trying to erase on MacOS Catalina

Board used to work properly, but attempting to re-connect after a wipe of my MacBook.

Log.log is attached.
Is there some compatibility issue with Catalina or are there other program installs required besides the nRF-Command-Line-Tools and JLink Driver?
