I emailed a teacher who uses Creo on Macs in his school and has lots of experience with his students installing on their computers at home. Let's hope he has seen this before.
A couple of weird/not so helpful ideas
If its a desktop Mac turn the monitor upside down Only kidding 😞
If you have a spare screen, plug it into your Mac and connect as a projector. There may be an option to invert the image (for projectors mounted in the ceiling).
