Mac compatibility
Can you play Tom Clancy's Rainbow Six Siege on a Mac?
Short answer: No. Rainbow Six Siege uses BattlEye, and Ubisoft has not enabled BattlEye's Wine/Proton mode — so the game refuses to start on Wine-based tools like Grapple.
What we know
Steam's requirements for Rainbow Six Siege state that the game contains BattlEye anti-cheat technology, and Ubisoft's own help pages describe BattlEye as the anti-cheat protecting Siege.
BattlEye installs a kernel-mode driver on Windows. Grapple is built on Wine, which runs Windows programs in user space with no Windows kernel, so that driver has nothing to load into.
BattlEye does offer a mode that works under Proton (the Wine-based layer on Linux), but each developer has to switch it on. Ubisoft has not done so for Siege: AreWeAntiCheatYet lists Rainbow Six Siege X as denied.
Steam lists the game for Windows only, with DirectX 12 in its requirements. Only Ubisoft can change this answer — no Grapple setting can.
Steam lists Rainbow Six Siege for Windows only. There is no Mac version.
What to do instead
There are no Grapple settings that get around a kernel-level anti-cheat block, and we won't suggest workarounds that could get your account banned. If the publisher offers cloud streaming, that runs on a Mac; otherwise it needs a Windows PC.

Test record
Not tested by us: the block is documented by the publisher or anti-cheat maker (see sources), and we don't try to bypass anti-cheat.
FAQ
Can I play Tom Clancy's Rainbow Six Siege on a Mac?
No. Rainbow Six Siege uses BattlEye, and Ubisoft has not enabled BattlEye's Wine/Proton mode — so the game refuses to start on Wine-based tools like Grapple.
Why doesn't Tom Clancy's Rainbow Six Siege work with Grapple?
Tom Clancy's Rainbow Six Siege relies on BattlEye, which uses a kernel-mode driver on Windows. Grapple is built on Wine, which runs Windows programs in user space without a Windows kernel, so that driver can't load — and the publisher doesn't allow Wine-based layers. The same applies to CrossOver and other Wine-based tools. Only the game's developer can change that.
Will a future Grapple update make Tom Clancy's Rainbow Six Siege work?
Not by itself. Anti-cheat blocks like this are decided by the publisher, not by compatibility tools. If the publisher changes its policy, we'll re-test and update this page.
Is there a Mac version of Tom Clancy's Rainbow Six Siege?
Steam lists Rainbow Six Siege for Windows only. There is no Mac version.
