I have had a problem on a couple of PCs (not Macs) where the 3D view would look empty - although the model was still there and could be selected - just not seen.
These PCs use GeForce graphics cards.
When I uninstalled a program call "GeForce Experience" all worked as expected.
Here is a post about the problem ...

GeForce card installers can install a lot of extra software - all you need are the drivers.
