Starting in 1989, following the release of Apple’s first CD-ROM drive in 1988 (the AppleCD SC), Apple began distributing software updates and technical information about it’s products on CD. In addition to downloading these for my own use, I am including links to online sources to make it easier for others to find these CDs and I’ve included links to the relevant Apple Direct/Directions articles that describe the contents of each CD. I have found these CDs incredibly useful for learning about and setting up these old systems.
Tag: Macintosh System Enablers
In the past when Apple released new computers the system software was revised. To get around this problem system enablers were written which contained information necessary for newer computers to start up. All Apple computers released since system software 7.1 (September 1992) require a system enabler to start up.
The information in this post was taken from an the Apple knowledge base (TA28948) with the assumption that the source article may be removed in the future (like many other articles that dealt with the vintage systems). I have updated the table to link to copies of the System Enablers that are currently being hosted by the Internet Archive. For additional information on how to use these enablers see: Selecting your System Software
As I mentioned in my Setting up your vintage (classic) 68k Macintosh not every Macintosh System can run every OS, for example System 7.5.5 was the last version to support the original Macintosh Systems with their Motorola 68000 (68k) processors, 7.6 required Systems with a 68030 and 32bit clean ROMs, with support for 68k processors ending with System 8.1. I also include some information about PPC systems, but my main focus for this page is 68k systems.
