OSC is not working on Pd-0.39.2-extended-test4.app. This is JUST the OSC external; OSCroute, sendOSC, and dumpOSC all work fine. Is OSC deprecated? If so, then the help files should not include it!
OSC is just the library, you need to load it before using the OSCroute etc objects, but it doesn't do anything on its own.
