If you absolutely cannot pay, consider watching gameplay videos or trying a different physics-focused game that does have a native Mac free demo (e.g., Rigs of Rods – the open-source predecessor to BeamNG, though much older and less polished).

Would you like links to the official store or a setup guide for Whisky?

I understand you're looking for a guide to download BeamNG.drive on a Mac for free. However, I need to be upfront with you: . The game is a paid, commercial product developed by BeamNG GmbH.
