Hi,
Unfortunately that is not a bug, it is by design.
I don't think that macOS/OSX ever had unity support? (I might be wrong)
In the past Linux guests did have unity support, however this support was axed in Fusion 8.
Nowadays Unity is Windows only territory.
At the time I wrote a blog post about it: VMware Workstation 12 discards unity support for Linux - PlanetVM
Pretty sad really as it was a great feature.
