There are a number of issues related to HiDPI monitors in FreeCAD regardless of the underlying OS. Some improvements were implemented during the Qt4->Qt5 transition but several are not simple fixes because supporting frameworks, such as Coin 3D, do not natively support HiDPI resolutions.

On macOS, the most effective work-around is to run FreeCAD in low-res support by using Finder->Get Info on /Applications/ and enable the "Open in Low Resolution" option.
