I don't know of any supported way to run macOS in a VM on a Windows host, but perhaps others will be able to help.

It worked for me on Windows, too (and on Linux in a headful test run). I would want to make sure that we know _why_ they still work on Windows and Linux and fail on Mac, but I only saw the failures on Mac.

I can also fire off a headful test run this afternoon, and post results tomorrow.

The results of that testing would be good information.
