QuickTime Settings control panel

The QuickTime Settings control panel was provided by Apple Computer to allow users to manage the settings of QuickTime in classic Mac OS.

Early development
A Things! control panel was in development for QuickTime 1.x in 1992. It was intended to manage QuickTime components, called "things" at the time, but was never publicly released. The ability to manage these features later emerged on a per-file basis in QuickTime Player 2.5 and Pro.

A QuickTime Music control panel and Macintosh MIDI Manager were in development in 1995 for QuickTime 2.1, but were also never released.

Releases
The QuickTime Settings control panel was first introduced on July 22, 1996 as part of QuickTime 2.5, to manage CD autoplay and MIDI synthesizer settings.

With the introduction of QuickTime 3.0 in March 1998, it could also be used to manage registrations of QuickTime Pro accounts, which unlocked additional features.

Deprecation and replacement
QuickTime 6.0.3, released on April 25, 2003, was the last version supported by classic Mac OS. This control panel was superseded by the QuickTime pane of the System Preferences in Mac OS X.
