System 4.2
From WikiMac, Everyone's Mac Knowledgebase
System 4.2, which was also termed System Software 5.0 (not to be confused with System 5, which never really existed), incorporated Finder 6.0. It met the Macintosh public in October 1987.
Apple started to use "System Software" versions with this release of the Macintosh system software. Users were confused into tracking the System and Finder versions separately, and thus a "packaged" name for the OS was a lot easier on the users.
Several dramatic changes came with System 4.2:
- The About the Finder dialog box was improved to display memory usage. The mountain scene, previously there, would be re-located -- as a famous easter egg.
- On Macs that supported color, the Color menu made its debut. (However, it was not available for the "classic" all-in-one Macs.
- Finder copying dialog boxes now sported a progress bar and a cancel button.
- Several new utlities, including Backgrounder, DA Handler, Easy Access and Print Monitor, as well as Background Printing with the LaserWriter, were introduced.
- The Control Panel was updated.
- MultiFinder and thus the era of multitasking on the Macintosh debuted. (Though it is true that multitasking capabilities were available before then using Mac ROM author Andy Hertzfeld's app "Servant", it was not officially endorsed by Apple.)
- To go with MultiFinder was the Set Startup menu command in the Special menu, which allowed users to choose between the regular (single-task) Finder and MultiFinder.
- MiniFinder was done away with.
Of course, along with the additions also came the massive increase in size. System 4.2 was over 5 times larger than the previous Macintosh system version!
