Blue Box

(operating system)
The complete implementation of the Mac OS run-time environment on the more modern Rhapsody operating system. Blue Box is not an emulation layer; at any given time it will be based on the same source code and ROM image as the current version of Mac OS and will thus incorporate future Mac OS improvements.

Blue Box

A programming interface (API) for Apple's Rhapsody operating system, which later became Mac OS X. The Blue Box was the Mac Toolbox API, which enabled a Mac OS 9 or previous Mac application to run without modification. The Blue Box was renamed Classic in OS X. See Mac OS X, Classic Environment and Yellow Box.
