I myself don't understand why it is so difficult to understand. I want Rosetta off my machine so that I know positively if an app I open is PPC or not.

Nobody seems to have mentioned the easy way to determine which apps are PPC native (or Universal or whatever):

1. Open System Profiler & click "Applications" in the list on the left, under "Software." Wait a few seconds for your startup drive to be searched.

2. When the list of apps appears, sort by "Kind" & scroll down to the "PowerPC" entries in the alphabetized list

Advantages:

• Every item of kind "PowerPC" is positively an PPC app
• All PPC apps are listed in one place
• No need to mess with trying to launch anything to see what type of app it is
• The path to each item, version number, etc. can be seen by clicking on its entry
• For Terminal users there is command line version (system_profiler) with filtering options, one of which outputs only app info: system_profiler SPApplicationsDataType. (See Mac OS X Manual Page For system_profiler(8) for the details.)

Disadvantages:

• Only checks startup drive

If you have deleted or removed the file [ /usr/libexec/oah/RosettaNonGrata ] then it would complain about the file not being there. Put it back in the "oah" directory and all should be well. (Provided all the other rosetta files that are buried in other places around your disk are still where they were.)

If you've already deleted the file and can't simply put it back, restore it from a backup or copy it from the OS Install package files on the 10.6 install DVD.

Interestingly, the [ kern.exec.archhandler.powerpc= ] variable could be set to ANY unix program. Even one that you custom wrote yourself that, for example, asks you "hey, you've got a PPC only app. you sure you want to run it? [Yes] [No]". Food for thought.

Yup, that's what it was. I assumed reinstalling Rosetta would put the file RosettaNonGrata back. It doesn't. Restored it with Pacifist and now the Terminal commands work perfectly.
