Stuffit has officially been discontinued, so this expander is somewhat kept alive to expand old files. If you have olf SIT/SITx files - uncompress them NOW.

That being said, about hald my old SIT files are given an error "Implementation required for this operation is missing". Since there is no support from SmithMicro, I'm just hosed. (as you may be).

So when it works, it works well. When it doesn't, you are out of luck.

A historical archive expander but maintained

Way back in the day when computer storage was extremely limited and very expensive, compression archivers like ZIP were practically essential. In the late 1980s, StuffIt was invented and became one of the major players, esp. on Mac. While the current owner of Stuffit (Smith Micro) determined that StuffIt had reached end of life in 2019, they still maintain this expander application to open any StuffIt archives (typically with a SIT or SITX extension) plus it will open common formats like ZIP., RAR, and TAR. A tip of the hat to Smith Micro for not only maintaining the expander but optimizing it for the new M1.

You had one job!

I hadn’t needed to extract much else than zip files so never needed a utility like this until today where I needed to extract a .rar file someone sent me. I remembered the name Stuffit from back in the day and go figure, they’re still around with a version 16 product. I gave it a try and it fails to do the one thing I downloaded this program for. It said there was something wrong with the .rar file and couldn’t open it. Reading some of the other reviews, I go and download The Unarchiver and guess what? It opens right away with no issues.

Stuffit, you had one job. You’re at version 16! No time for you, the nostalgia isn’t going to cut it. Unistalled.
