Just installed UE4 on Windows and see that menu system is completely different about Android. Menu File->Package Project contains Android even if i do not set any of environment variables. Also Project Settings contains Platforms: Windows and Android. On Mac OS these menu items is absent. In Device Manager there ability to add unlisted device for Android platform and it not presence on Mac OS version. So as i understand there is no support for Android on Mac OS platform. (Thanks Epic for my lost weekend)
