Editing System 6 (section)

===Multitasking===
Macintosh gained cooperative multitasking in March 1985 with [[Andy Hertzfeld]]'s Switcher, which can switch between multiple full-screen applications.<ref>{{Cite book |last=Hertzfeld |first=Andy |title=Revolution in the Valley |publisher=[[O'Reilly Media|O'Reilly]] |year=2005 |isbn=0-596-00719-1 |pages=243–251}}</ref> It was not integrated, and was only sold separately by Apple. Not many programs and features function correctly with Switcher, and it does not share the screen between applications simultaneously. Systems 5 and 6 have [[MultiFinder]] instead,<ref name=":0">{{Cite magazine |last=Wiggins |first=Robert R. |date=March 1988 |title=All systems go (System Tools 5.0 with MultiFinder) |magazine=MacUser |pages=126}}</ref> which is much more mature and widely used in System 6. With MultiFinder, the Finder does not quit to free resources, and the system behaves as in the still-familiar multitasking fashion, with the desktop and other applications' windows in the background.<ref>{{Cite web |date=September 1, 1987 |title=Apple Talks About Multifinder |url=https://www.savetz.com/ku/ku/applelink_apple_talks_about_multifinder_september_1987.html |access-date=December 2, 2024 |website=Known Users}}</ref>
