Halo: Combat Evolved for Macintosh

Halo: Combat Evolved for Macintosh is a port of Halo: Combat Evolved for Apple Macintosh computers. It features all of the additional weapons, vehicles and maps included in the Windows PC port of Halo: Combat Evolved.

System requirements
Note: Halo will run normally on Intel-based Macs. However, due to having to run in the Rosetta PPC emulator, there is an impact on performance.

Trivia

 * Halo was originally for the Mac, until Microsoft's acquisition of Bungie, which prompted the Xbox, and later, PC version. The game was intended for use on PowerPC Macs, and will crash if used on a newer Intel Mac. Bungie and MacSoft have since released a patch allowing for universal use of the game.
 * With macOS Catalina and newer releases, 32bit apps like Combat Evolved are no longer supported.
