The CFM-68K Runtime Enabler is an extension which makes it easier for developers of applications to design their programs to run on both 680x0 and PowerPC computers without having to write separate programs for both processor families. On a more technical level, the Code Fragment Manager ("CFM") was originally introduced by Apple only for Macintosh and Mac OS-compatible computers based on the PowerPC processor. It allows applications to share their programming code through special files known as shared libraries. In addition to being able to share programming code, applications which are programmed to use shared libraries can reduce their memory requirements. In response to the success of the PowerPC version of CFM, Apple introduced a version of CFM for Macintosh computers based on the 680x0 processor. This version of CFM for 680x0-based Macintosh computers is the CFM-68K Runtime Enabler extension. Version 4.0 fixes a problem with earlier versions of this extension which could result in application instability and loss of data. Because of the potential quality impact of this problem, Apple strongly recommends that customers with earlier versions of this extension upgrade to version 4.0. You must have 680x0 computer running System 7.1, 7.5, 7.5.1, 7.5.2, 7.5.3, 7.5.5, or Mac OS 7.6 to install this
