Doom (Apple Macintosh)

The Apple Macintosh line of -based computers received ports of Doom, Doom II, and Final Doom between 1994 and 1996, each of which were sold as separate products. The porting work was performed by Lion Entertainment, Inc., under license from id Software and with as distributor.

Features
The Macintosh port of Doom, unlike the equivalent Doom95 for PCs, was integrated tightly with the operating system, with ability to be launched from the Finder, a menu bar, and custom control key shortcuts for various in-game menu options. Messages given by the game, such as the question asked when the player requests to quit, are actual Mac OS dialogs with the Doomguy's face for an icon.

System Requirements
The Macintosh port had the following minimum system requirements:
 * 68040 PowerPC processor
 * Mac OS 7.1 or up (not compatible with, requires emulation).
 * 8 MB RAM
 * 18 MB hard drive space for optimal performance; the games could run off the CD-ROM, but without music and with framerate issues.
 * 8-bit graphics mode
 * 2x CD-ROM drive for installation
