StuffIt soon became very popular and Aladdin Systems was formed to market it the last shareware release by Lau was version 1. Deluxe added a variety of additional functions, including additional compression methods and integration into the Mac Finder to allow files to be compressed from a "Magic Menu" without opening StuffIt itself. StuffIt was upgraded several times, and Lau removed himself from direct development as major upgrades to the "internal machinery" were rare.

Because new features and techniques appeared regularly on the Macintosh platform, the shareware utility Compact Pro emerged as a competitor to StuffIt in the early s. A major competitive upgrade followed, accompanied by the release of the freeware StuffIt Expander , to make the format more universally readable, as well as the shareware StuffIt Lite which made it easier to produce.

Prior to this anyone attempting to use the format needed to buy StuffIt, making Compact Pro more attractive. This move was a success, and Compact Pro subsequently fell out of use. Several other Mac compression utilities appeared and disappeared during the s, but none became a real threat to StuffIt's dominance. The only ones to see any widespread use were special-purpose "disk expanders" like DiskDoubler and SuperDisk! Apparently as a side-effect, StuffIt once again saw few upgrades.

The file format changed in a number of major revisions, leading to incompatible updates.

These had little impact on the Mac market, as most of these never appeared in an easy-to-use program on the Mac. With the introduction of Mac OS X , newer Mac software lost their forks and no longer needed anything except the built-in Unix utilities like gzip and tar. Numerous programs "wrapping" these utilities were distributed, and since these files could be opened on any machine, they were considerably more practical than StuffIt in an era when most data is cross-platform. It was designed to be extendable, support more compression methods, support long file names, and support Unix and Windows file attributes.

It also added a "block mode" option and several encryption options. Although Mac files generally did not use filename extensions , one of StuffIt's primary uses was to allow Mac files to be stored on non-Mac systems where extensions were required. So, StuffIt-compressed files save the resource forks of the Macintosh files inside them, and typically have the extension. Newer non-backwards compatible Stuffit X -compressed files carry the file extension.
