How to make the Editor appear?

So,

Mac OS X 10.9.3
Unreal Engine 4.2.1

As I open a Project the Editor won’t show. He seems to load it.
Also I have to force quit it when I load a project because the
engine simply does nothing. I would like my money back and
the developers to call this a beta or something. That’d be all.
Also this question space is super ******. It can remeber the text
I wrote but not the section? Great!

That worked. The engine folder in the Shared folder by the way.
