World generation not working on macOS

[remuzel]

Describe the bug

The world generation completely fails on macOS, and the mouse sensibility is absurdly high.

To Reproduce

Steps to reproduce the behavior:

1. Run ./build/open-builder on a macOS system.

This has not been tested on other operating systems.

Expected behavior

As per the attached image, the only thing that is generated is what seems to be an ocean.
Using the space key I am able to fly out of to infinity.
Using the shift key I am able to dive down under the water and sand down to oblivion.

Desktop:

• OS: macOS Mojave Version 10.14.6
