^^ I have no idea at all why the Mac OS can't be opened. After a bit of goooogling it seems like it might be some file-permission issue (https://www.reddit.com/r/Unity3D/comments/5xfgy2/unity3d_osx_application_cant_be...) and seem to require some extra work to open. Very weird, I will look into this more asap.
