Macintosh System Software 0.3 & 0.5: Release Details

Apple’s Macintosh System Software 0.3 & 0.5 was a revolutionary operating system that was released alongside the Macintosh computer in 1985. The software was designed and developed by Apple to provide users with an intuitive and easy-to-use interface.

On March 2, 1985, Apple released the Macintosh System Software 0.3, which introduced multiple folders, a new “Shut Down” command, and the installation of a “MiniFinder” application for quickly launching any chosen applications. The software also introduced new screenshots functionality using ⌘Command + ⇧Shift + 3.

Just six months later, on September 17, 1985, Apple released a new version of System Software, which included support for Macintosh Hard Disk 20. This version of the software was a significant upgrade from the previous version, providing users with more storage options and increased performance.
