MultiFinder

MultiFinder is a software application that was part of Apple's Macintosh operating system in the 1980s, specifically designed for the Mac OS System Software 7 and earlier versions. It enabled users to run multiple applications simultaneously on their Macintosh computers, providing a more multitasking-friendly environment. Prior to the introduction of MultiFinder, Macintosh systems operated in a single-tasking mode, meaning that only one application could be active at a time.
