The SDK's AUBase classes will I think work with 10.2.8 even - we've tried not to build in linkage dependencies with the basic AUBase implementation. The compiler and the SDK that you use to build your AU determines your compatibility - I'm surprised that a 10.4 build works with 10.3.7 because of the C++ changes between 10.4 and earlier. There is a compatible way of building C++ for 10.4 that I thought required 10.3.9

Other AU developers have built against 10.2.8 and that is still compatible to existing 10.4 systems... But this is getting harder to maintain given the changes for universal binaries.

The XCode documentation on both:
MACOSX_DEPLOYMENT_TARGET
SDKROOT

I just released a beta of several audio units that were compiled for 10.4 ("Current Mac OS"). However people have been able to open them with OSes as early as 10.3.7, which I didn't expect. Is there a reference for the earliest OS that each version of the coreaudio SDK supports?

Thanks, Tom
