If you're asking how Apple created masters, in the early days you'd literally ship a 650MB-ish HD off to the duplicator that contained all the data, and they'd take it from HD to a pressed CD, since it's trivial to convert an HFS volume to an HFS CD-ROM. The layout on the HD matched the CD, so you needed to re-order the data on the HD, grouping together files that would be accessed at the same time to be close to each other (the Sony PS2 system was notorious for lazy masters, which caused the CD to sit there seeking endlessly, because they skipped this optimization step).
Once CD-R drives were available for under $20,000 they probably adopted more reasonable methods. I recall seeing some MPW projects on Apple developer CDs, but since it was a scriptable environment suitable for damn near everything, it's no surprise they used it. Around this time I started mastering on Toast, back before Adaptec bought it, when it was still being made by Astarte, simply because it could handle everything I needed and was easy to boot. Though the PS2 projects were still mastered on those god-awful component-sized 2x burners (that required burning at 1x to get the error rate down to reasonable levels)...
I fired up the oldest copy of Toast I still had, which was 6, and in the advanced tab that slides out you can choose what type of disc (Mac, Mac/PC, Custom Hybrid, etc.) and on that tab you can choose to create it as HFS Standard with a simple checkbox. I don't recall there being huge functional differences between 5 & 6, 6 just organized things a little better. In 5 I think the options were buried off the menu that pops up off "Mac OS CD" in this image
