MacOS: Keyboard inputs are directed to the terminal, rather than to the game window

When launching eduke32 or mapster32 over the terminal on MacOS, all inputs end up going to the terminal in the background, rather than the game itself. Furthermore it is apparently not possible to have the window refocus and the inputs be directed to the game.

This is according to a user who would like to use mapster32 on a Mac machine (temporarily).

Even if this turns out not to be a bug, I would be happy to know any possible solutions or workarounds for this problem.
