Classic Environment

Classic, or Classic Environment, is a hardware and software abstraction layer in early versions of Mac OS X that allows applications compatible with Mac OS 9 to run on the Mac OS X operating system. The name "Classic" is also sometimes used by software vendors to refer to the application programming interface available to "classic" applications, to differentiate between programming for Mac OS X and the previous version of the Mac OS. Classic is supported on PowerPC-based Macs running versions of Mac OS X up to v10.4 Tiger, but is not supported on v10.5 Leopard and later, nor on Intel-based Macs running any version of Mac OS X.

Famous quotes containing the words classic and/or environment:

    A classic is a book that doesn’t have to be written again.
    Carl Van Doren (1885–1950)

    In a land which is fully settled, most men must accept their local environment or try to change it by political means; only the exceptionally gifted or adventurous can leave to seek his fortune elsewhere. In America, on the other hand, to move on and make a fresh start somewhere else is still the normal reaction to dissatisfaction and failure.
    —W.H. (Wystan Hugh)
