High Quality Content by WIKIPEDIA articles! PackIt is a software data compression utility for archiving and compressing files on the Apple Macintosh platform. It was the first such program to see widespread use on the Mac, and most Mac software archives accepted uploads only in PackIt format for some time. StuffIt, introduced in the summer of 1987, offered much improved compression, and PackIt quickly disappeared.
