What is Macintosh System Enablers?

System Enablers are system patches which purpose was to expand the System software so that it makes otherwise unsupported Macintosh models boot.  System Enablers are only useful for Mac OS 7.6.  Back in the 80's, every time a new Macintosh model was released, Apple had to add information to the System file about how to operate this model, so it resulted in a System software update release every time.  The use of System Enablers allowed to reuse the older System software without having to release a new one.  So, some versions of Mac OS require a System Enabler to run on certain hardware.

From Apple's old website:

This tables in this article list Macintosh computers and the versions of System 7.1 through Mac OS 7.6 that can be used with them. It also lists versions of any required enablers. To search the Technical Information Library for information on system software previous to 7.1 use the search string "system software and 7.0.1."
Use the following chart to determine which version of system software you should be using on your Macintosh computer:
