Concerning detecting Rosetta:

This is not the recommended way; for a better way, see http://
developer.apple.com/documentation/MacOSX/Conceptual/universal_binary/
universal_binary_exec_a/chapter_7_section_7.html

The sample code is a little more elaborate than necessary because
it's designed around the idea of testing any PID to see if it's
running in Rosetta, not just your own PID. In listing A-4, change
sysctlbyname_with_pid to a plain sysctlbyname to simplify it. Or if
you don't mind either way, just copy all the code and pass a PID of 0.

Shouldn't gestaltNativeCPUfamily or gestaltNativeCPUfamily selectors be used to detect if application is running under Rosetta? E.g. gestaltProcessorType gives 'PPC' and gestaltNativeCPUfamily gives 'i86'. Just an idea, I didn't test that.

The only supported way to detect whether an application is running in Rosetta is the one at the URL mentioned above. Other things which may work today are not supported.


Hope this helps,
Eric
