Release notes

Stuffit Expander Mac Os 9

Version 5.5 requires MacOS 7.1.1 or later with a minimum hardware requirement of a Mac II (68020 CPU). Supports PPC Macs.

Version 5.5 is the last that will run on m68k based Macs, and is the most popular version for vintage Macintosh abandonware.

Installation instructions

The 'bin' file is primarily for use with virtual Mac hard drive image management tools. Inserting this file in to a Mac volume will automatically create the required resource fork and creator information. On a real mac, bin files can be extracted with BinHex.

The 1.44mb disk image may be written with a USB floppy drive (the target Mac must also have a 1.44mb drive), and the ISO may be written to a CD-ROM or mounted in an emulator.
