Mac compatibility
Can you play Killing Floor 3 on a Mac?
Short answer: Probably not — Killing Floor 3 ships Easy Anti-Cheat, a kernel-level anti-cheat, and no Wine-based tool can load a Windows kernel driver. Untested, but the anti-cheat decides this one, not the graphics layer.
What we know
Steam lists Killing Floor 3 for Windows only. Its requirements call for DirectX 12, which Grapple runs through D3DMetal — but the anti-cheat decides this one, not the graphics layer.
Steam's store page discloses that it uses a kernel level anti-cheat, Easy Anti-Cheat.
Grapple is built on Wine, which runs Windows programs in user space without a Windows kernel. A kernel-mode anti-cheat driver has nothing to load into, and no Grapple setting changes that — only the game's developer can.
AreWeAntiCheatYet's entry for Killing Floor 3 was written before release and is marked speculative, so it tells us nothing reliable about Wine-based layers yet.
Grapple settings
Nothing verified yet. Where to start, based on its DirectX version (in the app, the same options are in the game's settings):
- DirectX 12 runs through D3DMetal, which comes with Grapple — a new install already uses it, and nothing needs downloading. See the Game Porting Toolkit guide.
- To see frame rates, turn on the Metal HUD:

Heads-up: this game uses Easy Anti-Cheat. Anti-cheat support can differ between Linux and macOS, so treat online play as unverified until someone has run it.
