Appearance Manager

In the classic Mac OS, the Appearance Manager controlled the overall look of the Mac GUI widgets and supported several themes. The Appearance Manager was originally developed for Apple's failed Copland project, but with the cancellation of this project the system was moved into newer versions of the Mac OS, notably bundled with Mac OS 8 and 9. However, the Appearance Manager is also available free as part of a downloadable SDK for System 7. The current version of the operating system, macOS, no longer directly supports the Appearance Manager.
