    Just to note this bug doesn't happen on 2020.2.4f1 and works as intended, and also happens for .mb files that Unity converts to FBX via Maya 2019. I personally couldn't recreate the bug in Windows, and things worked as expected (although it took a while), the FBX models in the project are opened without issue by Maya and seems to just be a bug in unity's loading of them in MacOS.
