System 7 Tune-Up 1.1.1

System 7 Tune-Up 1.1.1 is a minor OS upgrade Macs running System 7.0 or System 7.0.1.

Version 1.1.1 of the System 7 Tune-Up corrects a mysterious situation where folders, after having files dragged from floppy drives that underwent several complex and random operations, started disappearing (or becoming invisible), taking all other folders further down the alphabet (in terms of name) victim.

System 7 Tune-Up 1.1.1 installs the System 7 Tuner 1.1 extension, the LaserWriter 7.1.1 and StyleWriter 7.2.2 printer drivers, and Chooser 7.1. It also installs an invisible extension -- Tuna Helper -- directly into the System file.

Recommendations

 * System 7 Tune-Up 1.1.1 should be installed only after all printer and network updates and extensions are installed successfully.
