Mac download missing its Metal shaders
Your Mac download was missing Luduvo's Metal shaders, so it couldn't start.
What you see
The Mac client aborts straight away.
Who's affected

What to do
- Download Luduvo again from luduvo.com. Build 43 fixed the missing shaders.
Status
Fixed in build 43. If you still see it, update Luduvo first.
