Kingdom Rush 6 on Mac and Steam Deck

Yes, it runs on Mac. The Steam version supports macOS, and one $19.99 purchase covers both Mac and Windows. Apple Silicon Macs are in the minimum spec, and Valve rates it Playable on Steam Deck.

Minimum requirements

These are the store’s minimum figures; Steam lists no recommended specification for either.

If the resolution comes up wrong

Hold Option (Alt on Windows) as the game starts: when the splash screen finishes, a window opens where you pick the resolution. If it does not appear, close the game, open ~/Library/Application Support/kingdom_rush_genesis on Mac (on Windows, AppData\Roaming\kingdom_rush_genesis in your user folder), delete settings.lua and global.lua, and try again. If it crashes instead, see the crash fixes; if it runs slowly, set FPS to 30 or turn off VSYNC on page 5 of Options.

Steam Deck: Playable

Valve’s own test passed two checks and flagged two:

• The default controller configuration works.
• Performance is fine at the default settings.
• Some button icons shown are not the Steam Deck's.
• Some text is small enough to be hard to read.

There is no native Linux build; the Deck runs the Windows version. The game is also on iPad through the App Store, which is a separate purchase: see mobile.
