When I run an offline game and click "Start LAN Play" I get that same message. But, if I hit just Play, everything works.

Getting the exact same message even after the Halloween Update.

I would only expect to see this message when running on an Intel HD 3000 GPU. These GPUs are extremely slow and their OS X hardware driver is feature deficient, so it does not run UE4 games like UT properly. To try and make the editor usable we experimented with forcing these GPUs to use the simpler forward renderer, which has then caused this problem in UT. Unfortunately even when this is fixed you probably wouldn't be able to play the game at an acceptable frame rate on these GPUs.

Seeing this message under any other circumstance is definitely a bug.
