System Enablers: Current Versions & Change History (12/94)

Article Created: 4 February 1993

Article Reviewed/Updated: 13 December 1994

TOPIC -----------------------------------------------------------

This article lists the current versions of the Macintosh System Enablers,
and what the changes were made to past version.

DISCUSSION ------------------------------------------------------

In the past, when Apple has come out with new computers, Apple has also
revised the system software so it knows how to start up these new
computers. Revising the whole system software, however, is a very
time-consuming process, and Apple has been releasing new computers much
more rapidly than it did in the past.

The solution to this dilemma is the System Enabler file. A System Enabler
contains everything that is needed to boot (start up) a new computer (or
computers). All of the computers that have come out since system software
7.1 (September 1992) require a System Enabler to start up.

With System 7.5 a universal enabler, which supports all computers
introduced up to the introduction of System 7.5, has been developed. Future
computers will have an enhanced enabler shipped with them.

With System 7.5 a universal enabler has been developed which will support
all computers introduced up to the introduction of System 7.5. Future
