System 7 Tune-Up 1.0

System 7 Tune-Up 1.0 was released on January 13, 1992. It is not a complete system upgrade, but a patch in the form of an extension along with updated printer software provided by Apple Computer for Macs running System 7.0, 7.0.1, or 7.0.1P to handle low memory situations better.
If there isn't enough memory to run an application, Tune-Up was supposed to quit other applications not in use. It also switched to foreground printing automatically if there wasn't enough memory available for background printing. Tune-Up also fixed known bugs with File Sharing and PrintMonitor corruption.
Besides these features, the tune-up freed system resources from memory that weren't currently enabled -- notably AppleTalk. It also sped up network related activities, printing and, file copying.
It was quickly superseded by System 7 Tune-Up 1.1 and 1.1.1 to address other critical bugs.
