The Macintosh Application Environment (MAE) is a software package introduced by Apple Computer in 1994 which allows users of certain Unix-based computer workstations to run application software designed for classic Mac OS.
MAE uses the X Window System to provide the Macintosh Finder graphical user interface in a window. The final version, MAE 3.0, is compatible with System 7.5.3.
MAE was designed for Sun Microsystems SPARCstation and Hewlett-Packard systems. It was discontinued on May 14, 1998.
