How would an application ever tell which SDK it was built against?

Most apps don't need to know what SDK they were built against; they need to know what the current OS version is. That's what NSAppKitVersionNumber is meant to provide - what version of AppKit are you currently running against. It has _never_ been meant to indicate what version of the SDK you linked against.

Before you dismiss this message (Eric), I think the case in point is how CILinearGradient works. It is NOT backwards compatible. The Core Image guys probably (correctly) assumed that NSAppKitVersionNumber would return the version of AppKit _linked_ against rather than _available on the system_.

I don't know exactly what they assumed or how this was implemented, but I do think that the behavior you're describing sounds like a bug in CoreImage.
