[Vm-dev] MacOS vs MacOSX?

[Casey Ransberger]

Okay. Going to try to address this tersely. (I'm bad at terse!)

The original Mac OS ran on the Motorola 68000. When that platform went the
way of the way of the dodo, Apple switched to the PowerPC architecture.
During the period of time when Macintosh computers used PowerPC
microprocessors, Apple introduced Mac OS X. When the PowerPC platform went
the way of the dodo, Apple switched to x86 (we call this The Year Hell
Froze Over.)

While I'd reckon that that vast majority of Mac users are running above
ia64 now, you'll still find people running older Macs (the Macs have
historically retained their value and kept on kicking a bit longer than
most of the IBM PC clones.) You'll find some of those people here, in the
Squeak community, so I think there's a strong argument for keeping those
folks in mind.

Hope this helps!
