= SUMMARY =

This article lists the current versions of the Macintosh System Enablers, and change history information.

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 the release of system 7.5.3 or later, the listed computers in this article do not require a System Enabler.
