Building Lighting

i build alwayd failed on mac,i turn off the firewall ,it is no effect.

Hi,

I am having a problem building even the smallest scene. The build process does not get passed Building Lighting. It sits on 0% and never moves. It feels like something is blocking the build. Apart from placing a light and adding some basic geometry are there any additional steps that must be done to achieve a build?

I am running on a MacBook Pro i7 16 GB Ram, geforce 650M

I have tagged the latest version but have also tried older version to know avail.

Any help. much appreciated

I seem to have fixed this problem by turning off the firewall.

Does anyone know why the build process needs to contact the internet?

Its not a huge problem but I Ould like to know so I can configure the firewall correctly.
