Can you play Once Human on a Mac?
Short answer: Likely to work, but not tested yet — Once Human 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 Once Human for Windows only. Its minimum requirements call for DirectX 11, with DirectX 12 in the recommended specs.
Grapple translates DirectX 10 and 11 to Metal through Apple's D3DMetal or the open-source DXMT, and runs the DirectX 12 path through D3DMetal. That's an expectation, not a result — we haven't tested it yet.
AreWeAntiCheatYet lists NEAC Protect as Once Human's anti-cheat and records the game as "Running" on Linux/Proton rather than officially supported. Proton is built on Wine like Grapple, but whether that carries over to Wine on macOS is exactly what a test has to show.
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 - 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:
grapple set Steam hud on
Heads-up: this game uses NEAC Protect. Anti-cheat support can differ between Linux and macOS, so treat online play as unverified until someone has run it.

FAQ
Can I play Once Human 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 Once Human from working?
It uses NEAC Protect. Whether it accepts a Wine-based layer on macOS isn't documented anywhere we can cite, so online play may still be blocked. It also lists DirectX 12, which Grapple runs through D3DMetal. If the DirectX 12 renderer misbehaves, pick the DirectX 11 one in the game's settings.
Which DirectX does Once Human use?
Once Human's requirements list DirectX 11 and 12. 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 Once Human?
Steam doesn't offer a macOS build of Once Human; it's listed for Windows only.
