Out of all the Aladdin StuffIt products, StuffIt Expander is the only free one. StuffIt Expander 3.0, the first version, was a combination of BinHex 5.0's "Download -> Application", the original only StuffIt product that was free, the UnStuffIt application, and Compact Pro's "Desktop-Expand" feature. As soon as the first version of the all-in-one StuffIt Expander was released, it became a "must-have" for Macintosh users to use Macintosh files from BBS or Internet. With the release of StuffIt Deluxe 2.0, Aladdin introduced the "Expander Enhancer" (a System Control Panel named: "StuffIt Engine") which was bundled with all later version releases of StuffIt Deluxe and DropStuff, allowing StuffIt Expander and other programs that supported the Engine to utilize archives created by other programs such as .zip and .tar.

When running from a classic Mac OS desktop, this is one of those "must-have" utilities to use when extracting classic Macintosh ".sit" archived software downloaded from the Internet, and to be able to "Un-Stuff" many of archives accessed from the Macintosh Garden.

Architecture: 68k PPC

FAT binary, 68k & PPC native. Requires a 68020 CPU (Mac II) or later.

Mac OS 7.1.1 or newer - it will complain about installing on Mac OS 7.1 or earlier, but will allow you to install anyway and seems to run OK.

Not compatible with the earliest Macintosh 68000 CPU's such as those found in the Mac Classic, SE, Plus, or used by Mini vMac (Mac Plus ROM), etc.

The .md5 contains the checksum of the file, useful if you want to verify the file you download for instance.

The actual software, you get that from downloading by clicking "www", "ftp" or "mirror"

I downloaded the second DL and put it in my emulator folder, but since it’s a .md5 file and not a disk image I can’t get it to work. Anyone know a way I can get around this?

new install of 9.2.2 on a G4 PowerMac DA, DiskCopy v6.3.3 cannot recognize the .img file

Try dragging the "stuffit_expander_5.5.img" file over onto DiskCopy v6's icon and let the mouse go when the DiskCopy icon darkens in color. This action should see the .img file mount on the desktop.

Can somebody please upload this in a self-extracting archive format?

No, not as a raw self-extracting-archive (.sea). Classic Macintosh .sea files have executable data inside of the resource fork of the file, only. This resource fork is lost (discarded) when travelling over the internet from one location to another. This renders the self extracting part useless. The only way to send .sea files across the internet safely, is to place the .sea inside of a .zip or .sit, etc, archive and extract it at the receiving end. You already have those on this page.

But on a brand-new install of 9.2.2, you should already have a copy of StuffIt Expander, as it is included in with the install files. If it didn't get installed by default it will be located on the install media. Mac OS 9.2.2 installs carry StuffIt Expander & DropStuff version 6.0 on the install media. It will be located inside of an Aladdin folder.

I can't verify the md5sum because the CheckSum 1.3 utility is in .sit format.

As with the drag and drop method described for Disk Copy above, if the CheckSum utility's .sit file doesn't open by double-clicking it's icon, drag it over onto StuffIt Expander's icon and let the mouse go when StuffIt's icon darkens.

On a brand-new install of 9.2.2 on a G4 PowerMac DA, DiskCopy v6.3.3 cannot recognize the .img file downloaded from the www or ftp, and the mirror no longer works. I can't verify the md5sum because the CheckSum 1.3 utility is in .sit format.

Can somebody please upload this in a self-extracting archive format?

How to install .img file?

If you are wanting this for SheepShaver. Add the .img's name to the list of disks (in the SheepShaver Launcher). That will cause it to be mounted on the Classic Mac desktop once it boots up.

Run the installer from the mounted disk image.

".img" files simply to be opened with Disk Copy 6.
These files act like drives connected to the computer.

The archive I originally uploaded to this page (specifically intended for users without a working copy of StuffIt Expander installed) has long since been removed and replaced by other users...

I will amend this situation in due course.

In the short term and if you don't mind DL'ing large files, grab the Mac OS 9.1 install CD toast image (3rd DL in page) and burn it to CD.

It has StuffIt Expander 5.5 and Aladdin DropStuff 5.5 which you can access easily and install from.
The installer is located in: "Mac OS 9.1:Software Installers:Aladdin Software:Install Aladdin Software".
You don't need to install the 9.1 OS but its there if you ever need it Smile

Also install DropStuff 5.5 even if you don't intend on creating ".sit" files yourself, as it installs the StuffIt Engine into the System folder, giving StuffIt Expander much more functionality.

I uploaded a zipped toast version from the Old Mac Archive which is suitable for bootstrapping an emulator.

This saved my life. Cannot use CD/DVD under Win7_64bit. No way to get files across intact (my install was very minimal). This is a VERY useful post!

sheepmyshaver123 - I am *impressed*!!! Laughing out loud

How did you do that? I wonder if you could find in the Apps "C" page for "Color It! 3.0 LE" and post a DL link for that one too? It also gets the XML "NoSuchKey" error and it has been bugging me no end. Anyway. You are a genius. Much thanks.

Someone mixed up my first upload of Stuffit Expander, which has been enclosed in a file, which is also useable in Mac OS X systems. So my first upload was useable by Windows users, too.

I believe I've to re-create the stuffit deluxe download file as again...
(if so, I've to remember to initialize the .cdr file in Mini vMac first to make it readable by Mini vMac/System 6.)

Please, read the Description *before* you jump to conclusions.

This is *not* a duplicate. It is an installer for Stuffit Expander 5.5 in a zipped .HFV file. It is (primarily) for Windows users running Basilisk II or Sheepshaver. It gives them an easy method to install the Expander by simply mounting the .HFV as a secondary drive and running the installer. Once they have done that they are welcome to *upgrade* to Stuffit Deluxe from the link you provided as that happens to be in a .sit archive and they will then be at last able to expand it without having to futz around with HFVExplorer, or worse - run Stuffit on a Windows box!

This may be a moot point anyway as at this point in time if I try to DL Stuffit Expander 5.5 - I get the dreaded XML "NoSuchKey" error which seems to be prevalent Sad
