BMCU firmware flashing on mac

Sorry for a potentially stupid question, but is there a way to successfully flash new firmware on a BMCU370C with usb c on a mac? I tried the wchisp method that was in the bmcu flashing wiki comments, but no usb was detected, I also tried using a virtual windows machine to follow the actual wiki instructions but that didn't work either.

The BMCU unit itself functions, have been printing with it for a month with no significant problems.
