Oh my bad! I didn't build a mac version of 0.9.1 because I didn't think it was affecting Macs. I can build and post that tonight.
In the meantime if your macbook supports vertical resolutions higher than 1050 you can try to manually set a higher resolution in this file:
[your user folder]/masteroid/settings.json
Worst case if you update that file and the game fails to start you can simply delete the settings.json file and the game will generate a new one with default settings.
