Contrary to the other commenters rose colored glasses, as someone who ran OS9 at the time, it was indeed very unstable.

The entire MacOS classic line of OS’s were horrible for stability. Any small bug in any program could knock out the entire OS, and they did multiple times a day. Don’t get me wrong, the love put into the OS was palpable. That’s why you used it. It just crashed all day every day.

I want to counter the idea that OS 9 was either stable or not stable. I made money in grad school fixing people's Mac OS 9 setups, and I had many satisfied customers. Basically, one bad Apple spoils the barrel. If you add "crazy media network extension from hell" alongside all your dozens of working apps, then yes, the whole OS becomes unstable. Similarly with low-quality Photoshop plugins, OS startup services, odd hardware drivers or even corrupt font files.. yes, the whole OS can crash "daily".

On the other hand, like a great day at a public theater act, when it goes well, it really does go well. I have OS disks and applications saved to this day, in their own filing system in a drawer, that run great, look great, and are a joy to use. And so you know, months of daily, extensive use, with no crashes.

OS9 was very stable, but some apps weren't e.g. photoshop would crash a lot, and as there was no protected memory space for processes every app crash balked the entire system. Happy days.

go is one of the rare language i can imagine using on a 20+ yo hardware / software stack. The whole go tooling is so much focused on simple and performant design that i think it wouldn't be too bad of an experience.

The iBook G4 only officially supports Mac OS X and Classic (a Mac OS 9 virtual machine), don’t waste your time ordering old CDs that won’t work. If someone has managed to get Mac OS 9 running, they’ll probably post instructions or a download on a forum like Mac OS 9 Lives.

CodeWarrior wasn't an Apple product; it was a third-party IDE made by a company called Metrowerks.

CodeWarrior was commercial software, Apple's pre-OS X developer tools were called "Macintosh Programmer's Workshop".

It was bought up by Motorola/Freescale around the turn of the century and lived on as tools for embedded processors until fairly recently, although the later releases were based on Eclipse.

And now it does :)

nice, wish I had seen it earlier. :D
