To the best of my knowledge the only telemetry that OSX provides is crash logs, and only if you opt into it. You could argue that spotlight's (and Safari's) web search should be included, but I disagree.
I'm curious, why wouldn't you include Safari and Spotlight?
Because they aren't metrics, but search integration. So as I understand it, they equivalent to google instant (safari literally; spotlight on the same vein) and they claim not to retain data on them.
