Stuffit Expander 5.5

Stuffit Expander, from Aladdin Systems, is a freely redistributable tool for extracting Stuffit "SIT" archives on Apple Macintosh computers. Most Macintosh file archives are in this format. Unlike ZIP, Stuffit preserves special resource fork and creator type information required by Macintosh file systems. For the Microsoft Windows version, please see Aladdin Expander.

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.
