Mac compatibility
Can you play Crusader Kings III on a Mac?
Short answer: There's a native Mac version on Steam — the easy route. The Windows version doesn't list a DirectX version, and nobody has run it with Grapple yet.
What we know
Steam ships a macOS build of Crusader Kings III with the same purchase as the Windows version. Steam's Mac requirements list macOS Sequoia 15 or newer and an Apple M1 or Intel Core i5-6500 or newer. If your Mac meets those requirements, the native version is the better route — nothing is being translated.
The Windows version is what Grapple would run. Its requirements name GPUs but no DirectX version.
With no DirectX version published there is nothing for us to reason from, and we won't guess. Running it once would tell us more than any spec sheet.
