I didn't take this to mean that an app compiled with Carbon/Appearance Compliant can't run in OS 9. Isn't the Appearance Manager also in System 9? I haven't tried it because I rarely boot into OS 9 anymore, but I'm of the understanding that an app compiled with this combination would run in both OSs.
