Selecting text in the "Join Password" and "Admin Password" fields acts funny. It selects left of where you are actually clicking.
Also, I don't think shadows are working on Mac version.
I'll attach my console with a pretty prominent bug that I'm assuming is Mac specific. Hopefully Badspot reads this. The console is me attempting to join a server, then just hosting my own and loading a build.
I non-stop get the error:
LightManager::uninstallGLLights: no lights installed!
