Can you play MORDHAU on a Mac?
Short answer: Likely to work, but not tested yet — MORDHAU lists DirectX 11, which Grapple's DXMT layer translates to Metal. Try it on the Free plan and tell us how it went.
What we know
Steam lists MORDHAU for Windows only. Its minimum and recommended requirements both call for DirectX 11.
Grapple translates DirectX 10 and 11 to Metal — through Apple's D3DMetal or the open-source DXMT — so on paper this is a reasonable candidate. That's an expectation, not a result — we haven't tested it yet.
AreWeAntiCheatYet lists MORDHAU as supported on Linux/Proton, with VAC — Valve's anti-cheat, which doesn't use a kernel driver.
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 10/11: a new install is set to Automatic, which picks D3DMetal or DXMT for you. If the game won't start or renders wrongly, naming a layer is the usual next try:
grapple set Steam graphics dxmt - To see frame rates, turn on the Metal HUD:
grapple set Steam hud on
Heads-up: this game uses VAC. Anti-cheat support can differ between Linux and macOS, so treat online play as unverified until someone has run it.

FAQ
Can I play MORDHAU on a Mac?
Likely to work — not tested yet, but nobody has tested it with Grapple yet. That's what the game's published facts suggest, not a result. The page changes to Works once players report it working.
What might stop MORDHAU from working?
It uses VAC. The developer enabled it for Linux/Proton, but we know of nothing equivalent for Wine on macOS, so treat online play as unverified.
Which DirectX does MORDHAU use?
MORDHAU's requirements list DirectX 11. Grapple starts it on D3DMetal, Apple's DirectX 11 and 12 translator, which Grapple includes and uses by default.
Is there a Mac version of MORDHAU?
Steam doesn't offer a macOS build of MORDHAU; it's listed for Windows only.
