I'm not giving up on mac. I am however putting it on hold for now until the game is 100% finished.
I believe I can get a mac version running just as well as on windows. It's not a 100% sure thing yet though. I'll put my energies into mac support as soon as the game is locked down.
Right now VR, and polishing the game is the priority.
There has already been vast improvements made in terms of visuals, and game-play.
I expect the game to be finished sometime in April.
