ExecutablePPC 32-bit 64-bit Notes
macOS (OS X)
In 2006, the game received Intel support - rather than making it a universal binary, however; the developers decided to use Cider for this new app.
As a result, the game may be unplayable after 10.7 "Lion" due to this.
Even if it does work, it is still 32-bit only.
