The behavior dates back to the original Mac, which could only context switch between applications via a hack that simulated multitasking (the days of 128K memory, etc.)

Not really, no. Having >1 app at once only appeared with Multifinder, which appeared in System 5. https://en.wikipedia.org/wiki/MultiFinder https://en.wikipedia.org/wiki/MultiFinder So that came along in 1987 alongside Macs with 1MB RAM. It built upon Switcher, which appeared with the 512kB Mac in 1985. The reason all OSes now have file open/save dialog boxes is that the original Mac didn't have enough RAM to show a finder window alongside an app, so apps had to provide their own.

  I was referring to Switcher, from 1985, which I believe ran on 128k Mac's. I was referring to Switcher because it set the user experience patterns and expectations for how app switching should work that led to multifinder and OSX per-app switching patterns. The Mac OS has always been an app-first experience (leading users to tend to talk about the name of the app they are using) where Windows has always been a document-first experience (leading users to talk about the file type of the document they are opening). Apps and Documents are obviously both important, so this is a big of a ying and yang thing where it's clearly two sides of the same coin, and yet they lead to a bias to talking about, for example, keynote, which is an app, and to talking about PowerPoint decks, which are documents (again, a bias, not a totality).

    Thanks for the reply. > I was referring to Switcher, from 1985 Ah, OK. You didn't _say_ that, though. > which I believe ran on 128k Mac's. I don't think so, no. The story of its development is here: https://www.folklore.org/Switcher.html https://www.folklore.org/Switcher.html It mentions needing the RAM, but not what system version. MultiFinder came in with System 5: https://www.folklore.org/Switcher.html https://www.folklore.org/Switcher.html ... so, before that. I would guess System 2, which was contemporaneous, but I don't know. https://en.wikipedia.org/wiki/Classic_Mac_OS#Release_history https://en.wikipedia.org/wiki/Classic_Mac_OS#Release_history > I was referring to Switcher because it set the user experience patterns and expectations for how app switching should work that led to multifinder and OSX per-app switching patterns. Huh. OK. I had never considered that before.
