Beta 22 - OSX/Windows lighting inconsistency

I have a scene using GI, deffered rendering with HDR enabled and light probes. On Windows everything looks correct, light bounces as expected, non-static objects are lit perfectly. No problems.

When i copy the project to my iMac and let it bake lighting etc, all objects in the scene not marked as static are incredibly dark even when next to a very bright point light. The static objects in the scene seem better but somewhat darker than when on Windows.

Only thing different to a standard setup is that I'm using the procedural skybox with a nighttime sky.

Anyone else experiencing similar issues?

Thanks
