Are there any MacOS utilities for investigating hardware so I can begin implementing support for it?
Yes. Apple has quite a few useful utilities located at: ftp://dev.apple.com/devworld/Tool_Chest/Devices_&_Hardware There are at least three useful subfolders in this directory: • Apple_Desktop_Bus – utilities to work with ADB • NuBus_Slot_Manager – contains the Slots utility • Display_&_Video_Hardware – utilities for investigating video hardware Many thanks to Alan Palmer (apalmer@il.us.swissbank.com) for providing the above information.
