MPLAB IPE gives "Connection Failed" on MacOS

I was given a PIC32MZ board. I am currently very interested in lightweight cryptography, and the PIC32MZ seems like a great target. It even has BSD4.4-lite port! I was trying to use the MPLAB IPE and I kept getting:

Connecting to Starter Kit on Board...

Connection Failed.

Apparently, you need to run the MPLABCOMM program to install the USB drivers. The file is included with the IPE, but it apparently skips that step in the installation. The IPE worked magically after that.
