OK, you've answered my question. I'll just repair the errors when I see them, and go on my merry way.
However, the URL document you cited is outdated. It says Mac OS X supports Classic, but it doesn't specify which *levels* of Mac OS X. That article was published 2 years ago, and since then, Mac OS X has abandoned Classic and replaced it with Rosetta.
For the future education of you and your colleagues, see the following references:
"Mac OS X 10.4 Tiger supports Classic Environment"
"Classic applications do not work on Intel processor-based Macs, or with Mac OS X 10.5."
"The last time that Apple switched CPU families—from the Motorola 68K CPU to the IBM/Motorola PowerPC—Apple included a Motorola 68K emulator in the new OS that made almost all 68K software work automatically on the new hardware. Apple has supported the 68K emulator for 11 years, but stopped supporting it during the transition to Intel CPUs. Included instead in the new OS for the Intel-based Macs is Rosetta. However, Apple dropped support for Classic mode on the new Intel Macs."
"Rosetta does not support Mac OS 9/Classic applications, or those applications requiring a G4 or G5
"Mac OS Classic currently only runs on the PowerPC (PPC) platform and will not be ported to run on the new Intel based Macintosh computers."
Thanks for your help.
