Mac compatibility
Can you play Arma 3 on a Mac?
Short answer: There is a macOS version on Steam, which Bohemia calls experimental — that's the first thing to try. The Windows version uses BattlEye's kernel driver, which Grapple can't load.
What we know
Steam lists Arma 3 for Windows and macOS. Bohemia's own note on the store page says the macOS port is considered experimental and has various limitations, and lists macOS Big Sur 11 with an Apple M1 or a 2-core Intel Core i5 as its minimum.
The Windows version's minimum requirements call for DirectX 10 and the recommended ones DirectX 11 — both inside what Grapple's DXMT layer translates to Metal. The anti-cheat is the harder part.
Steam's store page discloses that the Windows build uses a kernel level anti-cheat, BattlEye, which must be removed manually after uninstalling. Grapple runs Windows programs without a Windows kernel, so that driver has nothing to load into.
AreWeAntiCheatYet lists Arma 3 as supported on Linux/Proton — Bohemia activated BattlEye for Proton in 2021. 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 for this game yet — but here's where to start, based on its DirectX version. If you get somewhere, tell us and we'll put the real settings here. You can change the same options in the app; from the command line, replace <bottle> with the name of the Windows environment the game runs in — bottle is the CLI's technical term for it.
- 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 <bottle> graphics dxmt - To see frame rates, turn on the Metal HUD:
grapple set <bottle> hud on
Heads-up: this game uses BattlEye. Anti-cheat support can differ between Linux and macOS, so treat online play as unverified until someone has run it.

FAQ
Can I play Arma 3 on a Mac?
Bohemia Interactive sells a macOS version of Arma 3 on Steam, and calls the port experimental with various limitations — read Bohemia's list before buying it for that platform. Won't run. BattlEye loads a kernel-mode driver on Windows, and Grapple runs Windows programs without a Windows kernel — there's nothing for that driver to load into. No setting changes this; only the game's developer can. That's what the game's published facts suggest, not a result. We publish a verified status only after running the game on a real Mac.
What might stop Arma 3 from working?
It uses BattlEye. The developer enabled it for Linux/Proton, but we know of nothing equivalent for Wine on macOS, so treat online play as unverified. There is a native Mac version — that's the way to play it on a Mac.
Is there a Mac version of Arma 3?
Bohemia Interactive sells a macOS version of Arma 3 on Steam, and calls the port experimental with various limitations — read Bohemia's list before buying it for that platform.
How can I try Arma 3 myself?
Grapple's Free plan runs one game, forever — enough to settle this one. Add Steam in one click (launchers and Windows tools never count as your game), install the game and launch it: that first launch is what claims it, and you can swap it for a different game once every 30 days. If it won't start, try the other graphics layer in the game's settings. Then send us the result — the game and where you bought it, your Mac model and macOS version, the engine and graphics layer it ran on (grapple info <bottle>), your in-game settings, the frame rate from the Metal HUD, and screenshots of any error or a diagnostics report (grapple report <bottle>) — and we'll publish it here once it's a real test run.

Try Arma 3 yourself — and tell us
Grapple's Free plan runs one game, forever — exactly enough to settle Arma 3. It's claimed the first time you play it, launchers and Windows tools don't count towards it, and you can swap it for another game once every 30 days. Install it, play for a bit, and send us what you saw. Every result — working or broken — decides what we test next, and verified results get published here with credit if you want it.
What to send
- The game and where you bought it (Steam, GOG, Epic…)
- Your Mac model, chip and macOS version
- The engine and graphics layer the game ran on —
grapple info <bottle> - The resolution and graphics preset you played at
- Frame rate from the Metal HUD, and the scene you measured it in —
grapple set <bottle> hud on - Screenshots of any error, plus a diagnostics report —
grapple report <bottle>
In those commands, <bottle> is the CLI's term for the Windows environment the game runs in — type its name instead. How to create a diagnostics report — it collects the game's settings, versions and logs into one zip, with your username removed.
