Macintosh Application Environment is a software application that provides a virtual Macintosh environment in an X window to users of HP workstations running HP-UX or later SPARCstations running Solaris.
Through 68LC040 emulation and native extensions, MAE lets users run off-the-shelf Mac OS-compatible, 680x0-based business productivity applications. MAE provides interoperability with other Mac OS-based systems in the enterprise, with the ability to easily manipulate UNIX files and execute UNIX applications from within a Macintosh environment. Users can also copy and paste text and graphics between UNIX and Mac OS-compatible applications
