On my Late 2013 MacBook Pro, launching Aperture as a test case causes gfxCardStatus to notify me of a switch in graphics cards. On my Late 2013 Mac Pro, it does not. But I haven't yet determined whether that is because gfxCardStatus doesn't work on a Mac Pro or because the Mac Pro doesn't switch graphics cards.
Launching my application on the Mac Pro doesn't give me a gfxCardStatus notification, either, but again I don't yet know why. I haven't tried it yet on the MacBook Pro -- later today.
