Free, though tedious, solution for Intel Mac users. These instructions will NOT work for M1/M2 machines. Writing these directions from memory after just updating an old Spider IV 75 from 1.x to 2.x, hopefully they're accurate.
* Install Virtualbox: https://www.virtualbox.org/wiki/Downloads or if you're a Homebrew user `brew install virtualbox`
* Download free Windows Virtualbox VM: https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/
* Start Virtualbox and Import the VM, or just double-click the .ovf file that came with the VM download
* In the VM Settings > Display > disable 3D Acceleration or the VM likely won't start based on my personal experience
* Connect your Floorboard to your Mac via USB
* Start the VM
* Add the Floorboard to the VM USB
* Do everything else within the VM, download and install Monkey, open Monkey, login via Monkey, yada yada and it should all work fine
