Wouldn't that make all applications run on OSX faster on a dual processor?
Or is it still only for applications that were specifically designed for
multiple processors?
In 9 only the "main processor" was used for everything unless an application was written to use 2 processors. Basically, the second processor was idle most of the time.
In X, Apps will run on only one processor unless they are written to run on 2.
Which, as it's a fairly simple compile-time switch in many cases, a minor re-write in others, most CPU-intensive apps do, in fact use both.
What X does is allow apps to run on either processor. ie; processor 1 can run your web browser while you surf the web, while processor 2 is running toast and burning a CD.
Many parts of OSX itself, particularly the Finder are themselves multi-thread compliant, meaning they use both processors as needed. This is what makes a dual-processor system not quite the black/white decision you make it seem to be.
