Mac compatibility
Can you play Crusader Kings II on a Mac?
Short answer: There's a native Mac version on Steam — the easy route. The Windows version lists DirectX 9, so it's a reasonable Grapple candidate, but we haven't tested it.
What we know
Steam ships a macOS build of Crusader Kings II with the same purchase as the Windows version. Steam's Mac requirements list OS X 10.11 (El Capitan) and an Intel Core Duo, so check it against your Mac first. 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 minimum requirements call for DirectX 9.0c.
DirectX 9 goes through WineD3D, Wine's long-standing graphics layer. That's an expectation, not a result — nobody has run this one with Grapple yet.
Steam lists the base game as free to play.

Nothing verified yet. Where to start, based on its DirectX version (in the app, the same options are in the game's settings):
- DirectX 9 runs through WineD3D, Wine's own graphics layer, which Grapple picks for older games by itself. Nothing to set.
- To see frame rates, turn on the Metal HUD:
