A new Sound Manager API, version 2.0, replaces the older ad hoc APIs. ![]() In the theme of the "blue" project, improvements in System 7 are significant but incremental. : 96–98 ĭevelopment of the ideas contained on the blue and pink cards proceeded in parallel under different teams, with the "blue" project leading to the release of System 7 in 1991 the "pink" project was eventually spun off into a dedicated company, Taligent. : 96 Improvements that seemed achievable in the short term were written on blue index cards, longer-term goals like true multitasking on pink cards, and more ambitious ideas like an object-oriented file system on red cards. In March 1988, : XXIII–XXIV shortly before the release of System 6, a group of senior technical staff and managers at Apple held an offsite meeting to plan the future course of Mac OS development. : 133 Many of the assumptions of the System software architecture were obsolete – mainly, the single-tasking model, the replacement of which had first been examined in 1986's Switcher and then replaced with MultiFinder in System 5. The operating system was beginning to fall behind competitors like Microsoft.
