So, without further ado, hereвЂ™s a picture of a Swift Toolbox app running on Mac OSВ 9.2, on my friend NadineвЂ™s Power Mac G4. Is this useful? No! Absolutely not! But neither was ROSE-8, and yet I still learned a lot doing it.ДЄs you probably guessed, I managed to accomplish this, or I wouldnвЂ™t be writing this blog post.

I package it up as necessary for Mac OSВ 9.I compile it for PowerPC with (a version of) the Swift compiler.

I write Swift source code that calls Carbon / Toolbox APIs.

Since I learned to program on Classic Mac OS, and years later spent a good chunk of my career working on Swift, IвЂ™ve had the tantalizing thought that IвЂ™d like to write a program in Swift and run it on Mac OSВ 9. Apple never released a 64-bit version of Carbon, presumably to encourage developers to move to Cocoa, and with last yearвЂ™s macOS Catalina, support for 32-bit apps was dropped entirely with very few exceptions. (h/t Marshall Elfstrand for the video link.)Д¬lassic ended with the switch to Intel processors back in the 2000s, but Carbon worked all the way up to last year, macOS Mojave. ( Sound familiar? 7) Fun aside: This is the reason (one of the reasons?) Core Foundation exists-to provide a common interface between Carbon and Cocoa. You basically just recompiled your app and added an extra annotation saying you were вЂњCarbonizedвЂќ.

6Д¬arbon was a packaged-up version of the old Mac OS Toolbox APIs so that you could write Mac OSВ X apps the same way you always had.

Think of it like Wine / CrossOver rather than VirtualBox / Parallels.

But its life ended with the switch to Intel-powered Macs-Classic was built on running the instructions in the original apps directly, only having to provide compatibility shims for libraries. It really was quite effective, and actually survived longer than booting into Mac OSВ 9 (which never received support for newer PowerPC processors). Because the Classic environment was itself an app, all the programs that ran inside it were protected from interfering with other Mac OSВ X programs and vice versa. The Classic environment set up a sandbox that looked enough like Mac OSВ 9 to run Classic Mac OS programs directly in Mac OSВ X. But Apple didnвЂ™t want to just leave OSВ 9 programs behind, so they did two things: Mac OSВ X was a huge step forward from Mac OSВ 9 in a number of ways, including preemptive multitasking so that you could actually run multiple things at once. Its successor Mac OSВ X 5 also ran on PowerPC when it first launched it wasnвЂ™t until 10.4 that Apple began to switch to Intel processors instead, and 10.6 when PowerPC was finally dropped. Mac OSВ 9 ran on PowerPC processors, which were also used in the GameCube, PS3, and Xbox 360 earlier versions of the OS had started on MotorolaвЂ™s 68k CPU series. 4 If a program crashed or overwrote memory it wasnвЂ™t supposed to, there was a good chance youвЂ™d have to restart the whole system.

It also dates from the days when only one program could run at a time because of that, even the latest version uses cooperative multitasking to run multiple programs-that is, a program has to yield its time to let others run. 3 It was one of the first OSs to use a GUI at all, something that we pretty much take for granted these days. Twenty (!) years ago, before the macOS 2 we know today, there was another operating system known as вЂњMac OSвЂќ. This year I decided to seriously attempt something that IвЂ™d thought about in the past: getting a Swift program to run on Mac OSВ 9. Last year I implemented the worldвЂ™s best code visualizer. And while pranks on April FoolsвЂ™ seem less and less fun 1, obvious jokes and whimsy, not at anyoneвЂ™s expense, are still something I believe inвЂ¦and even better if they actually work. While this year is a sober one due to current events, I think a lot of people still appreciate what people are creating and sharing to keep spirits up, whether that be music or art orвЂ¦impractical programming projects. ItвЂ™s April 1, and that means itвЂ™s both April FoolsвЂ™ Day and the anniversary of the founding of Apple Inc.
