Why is my area light doing nothing?

I set up a very simple scene with two cubes, a sphere and an area light.

problem: area light doesn’t seem to light anything.

I disabled skybox and directional light to see exactly what was going on, and really nothing is going on at all.

What’s going on?

There’s that warning about SM2.0 and GLES2.0 that makes no sense to me, but I can’t see why hardware would be a problem unless Area lights were not working on Mac (they do, right?)

I’m having the same problem! I’m on Windows so it can’t be just a Mac thing.
